We had a perhaps similar problem using NCD 17-inch X terminals where
various control panels and such would be placed such that they hang
off the edge of the screen. The .avsrc file setting

ScreenSize       1024x768

caused AVS to place things such that we could see them. Perhaps a
similar setting in your .avsrc will help AVS draw your main panel the
right size too. Also, there's another setting which tells AVS your
window manager:

WindowMgr        mwm

It doesn't seem to do anything earthshaking but it probably can't hurt
to tell AVS everything about your environment.

Hey Allen,

You can start up AVS with a size option (like: "avs -size 500x400") 
which produces a scaled down interfacei (widgets and all.  It's like 
a "mini AVS".  Unless you reset the viewer windows (as you indicated
in your message), they will continue to come up their default sizes.

Does this do the trick for you?

Does anyone have a module to calculate evolutive (3-D) power spectra.  Labview
has something for the Mac close to what I am looking for which produces a Gabor Spectrogram.

My data are time series which look something like this:

Time	Value
1	60
2	62
3	59
4	53
5	58	
6	62
7	61
8	65
etc.
for up to 2000 - 3000 data points.

I would like to calculate the power spectra in a moving window (the data should be 
detrended and clipped), normalize and smooth the results and plot as a contour map
with the x-axis = frequency, y-axis = time, and z-axis = power.

Any suggestions or information would be greatly appreciated.

Many thanks,

David

I am looking for a module that will produce contour lines at more than one
level. The currently available modules ALL have a single threshold or level
parameter, ie. they produce contour lines at ONE level only. It is somewhat
anoying to have to instantiate 30 modules if you want to produce a contour map
with 30 contour levels.

Is there a module that can produce contours at more than one level, or is there
a way to this with the current modules?

I am writing a module that orients three clip planes to cut away a
portion of the geometry, but I keep getting a rather bizarre error when
executing the appropriate portion of my code.  I get:

   error clip plane in perspective hell

in the window I booted AVS from for each of the three clip planes
once that part of the module is reached.  I get this whether I use the
geom_edit_set_matrix routine or the geom_edit_concat_matrix routine. 
I'm fairly certain I have the clip planes positioned properly, and all
my variations of my code and transformation matrices produce the same
error.  

Has anyone ever seen this before?  Can someone explain what may causing
this?

Thanks,

Steve

I have the same question. We need contour lines or a contour plot surface
that consists of geom objects so that they can coexist with other geom
objects in a complete display.

if you want to contour a 2D field, try out the contour_field module at
the IAC, we have found it to work fairly well with our 2D fields.  for
3D fields, the macro module construct simplifies instantiation, but it
doesn't simplify setting the levels.

I am working with a grided bathymetric data set (output from MBGRID)
with many missing elements.  These elements are flagged as "-99999.9"
and the "good" elements are positive values.  How can I mask out these
bad data points when I create a contour plot, calculate statistics,
etc?  I have tried the 'threshold' module to change the bad data values
to zero but this is certainly not the solution to the problem -
skewness prevails.  Does AVS have the IEEE arithmetic representation
for Not-a-Number like MATLAB?  And, if so, how does AVS handle such a
number?

Please keep in mind that I am new to AVS having only recevied my
evaluation copy a few days ago and I can't RTFM because I don't have
TFM.

Any hints would be greatly appreciated.  Thanx.

Greetings,  I have a question about creating short animations without the AVS
animator using the GEOMETRY or IMAGE viewer.  Is there any other way to 
animate a scene with multiple objects in the geometry viewer without transfer-
ring the scene to the image viewer and appending frames in the image viewer
menu?  I occasionally get weird results using this method and would like an
alternative.  Thank you 'a priori'.

Hello,

I would like to write a AVS module on CM5. This module will be
implemented by C plus CMMD message passing library and programmed 
as the host-node programming model.

Is there any example that can shows me how to write down the 'make'
file of this program? I already get the make files of 'pure' AVS 
module and 'pure' CMMD program. But, I get some trouble to merge them
together. Any idea? Thanks for your help.

Has anyone seen a data input module for AVS that will import an XVIFF

(N.B. I've looked through the avskhoros directory at the IAC, and 
      there is a couple of C routines, however they are not AVS modules.
      I have an end-user who is not wanting to cut code, and just effectively
      wants to read a VIFF file directly into AVS.)

Replies preferably by email.

Thanks

ADVANCED VISUAL SYSTEMS ACQUIRES UNIRAS 

Acquisition Benefits Customers of Both Companies by Providing Greater
Breadth of Graphics and Visualization Solutions Worldwide

Waltham, Mass., September 7, 1993 -- Advanced Visual Systems Inc., a
leading developer of visualization and software development products for
technical professionals, announced the acquisition of UNIRAS, a
Denmark-based supplier of visual data analysis and presentation graphics
software and software development tools for scientists, engineers and

has been a leading supplier of advanced 2D graphics tools for data
analysis, display and presentation since 1980. As a result of the
acquisition, the company will now be able to offer customers a
comprehensive range of application development tools and graphics solutions
through expanded worldwide support and distribution channels.

"We are very excited about working with the high caliber of technical and
sales professionals we have met at UNIRAS. This acquisition will allow us
to provide to customers of both companies an outstanding range of graphics
solutions -- from GUI builders and 2D graphing and plotting software to
state-of-the-art 3D visualization and application development frameworks,"
said George Brandt, president and CEO of Advanced Visual Systems.  "The
acquisition of UNIRAS immediately doubles the revenues of AVS Inc., the
installed customer base and the size of the company, which translates to
more market share, resources and products. We have enhanced our ability to 
both meet the needs of our customers and maintain global leadership in the

Dear AVS User,

I am pleased to inform you that, as of today, we have acquired the assets
and assumed immediate ownership of UNIRAS, a Denmark-based software company
well respected for its graphics tools. UNIRAS supplies visual data analysis
and presentation graphics software and software development tools for
scientists, engineers and programmers around the world, and we have admired
them for many years. When the opportunity arose to purchase the company, we
acted quickly.

There are a number of reasons why the UNIRAS acquisition appealed to us,
and why we think you will appreciate these advantages as well:  

Both companies provide excellent products and technology in similar
markets. We both have strong R&D teams and our distribution and support
channels complement each other. AVS has established strong distribution and
support capabilities in the U.S., Japan and parts of Europe -- UNIRAS'
distribution and support in Europe and the U.S. augments our coverage.

The acquisition immediately doubles the revenues, installed base and
size of AVS, giving us more market share, resources and products with which
to better serve your future needs. We were able to complete the transaction
from our cash reserves; no outside financing was required.

Both companies provide solutions to end-users and application developers
in technical and business markets. UNIRAS has been marketing and delivering
developer solutions for years and this expertise is of significant value to
AVS as we increasingly focus on selling application development frameworks
for visual application development.

UNIRAS brings a host of well-proven products that are natural extensions to
AVS Inc.'s own successful products. These include the agX/Toolmaster suite
of graphics tools and Motif widgets; FGL/AGL Fortran graphics libraries;
the Unigraph+2000 interactive visual data analysis product; and a large
collection of software drivers for more than 400 hardcopy output devices.

Users of UNIRAS products include major petroleum companies, automotive and
aerospace organizations, oceanographers, educational institutions,

AVS plans to continue to sell and support AVS and UNIRAS products on a
worldwide basis through both existing distribution channels. We will
combine sales operations in the U.S. and the United Kingdom, and we plan to
continue to operate the UNIRAS subsidiaries located in Germany, France and
Italy, as well as establishing a new sales subsidiary in Denmark. We also
plan to maintain a significant R&D and customer support organization in
Denmark. All European operations will use the name AVS/UNIRAS.

In summary, we view the combination of AVS and UNIRAS as one that increases
the value of the corporation to customers and employees, and are truly
excited about the prospects ahead.

We'll be in touch with many of you in the next few weeks. In the meantime,
if we can answer any questions, please feel free to contact me directly.

I will likely be using AVS or a comparable visualization package
soon, probably by remote.  I am trying determine what would be the
best hardware configuration for me to use.  I have seen AVS run
remotely on a DECstation 5000/25 with 256pseudocolor monitor (19in?)... 
it seemed to run quite slowly. I am considering Silicon Graphics 
machines, Sun's, DEC's, etc... in the price range of $5000-20,000.  
If you have any ideas about platforms, graphics accelerators, etc... 
I should be considering, or know of a good place for me to find out
this information, please let me know (dhloughl@eos.ncsu.edu).
Thank you - Dan Loughlin.

The buy-out of UNIRAS by AVS is certainly interesting news.  But I
wonder if AVS Inc have shot themselves in the foot a little.  They are
just about to release a graph plotting module (AVS/Graph) bought from
another company which has already come through beta test.  But this is
exactly the sphere in which UNIRAS excels, and it would seem to make
sense to base their "plotting" graphics on UNIRAS instead.

Does this mean that AVS/Graph will be withdrawn or will we see yet
another choice of graph output?

It was not mentioned in any of the previous AVS/UNIRAS posts, but
UNIRAS just came out with their own visualization software called
DirectInsight.  I saw it at SIGGRAPH and was pretty impressed.
It is a turnkey systems so there is nothing to program.  What is
going to be the status of DirectInsight relative to AVS?

Hi,

I have a few beginners questions about avs.

- Does a FAQ for this newsgroup exist ?
- Where is an ftp site for modules ?
- What avs data format is the best choice to read data which is block 
  structured. In each field the data is represented as curvilinear fields.
  Is the ucd format suited for really big data-sets (1.000.000 cells)?
- How can I change the backgound color in the geometry viewer for postscript
  output?

Thanks in advance for your help.

I have a program that generates a sequence of HDF image files
and I use AVS to record them on videotape.  To record them,
I use this network, Read_Seq_Anim -> READ_ANY_IMAGE -> OutputVideoCreator.

I'd like to be able to add text to my images before I record them.
I've tried a couple of methods that were not ideal or did not
work.

The first was to use Label -> Geometry Viewer -> Composite
with the other input to Composite being my HDF image from
READ_ANY_IMAGE.  This did not work because the image coming out
of READ_ANY_IMAGE was not the same size as the image coming out
of the Geometry Viewer.  Is there anyway to adjust the size of
the image coming from the GV to an exact dimension?

The second method was to put the Image_Viewer module after
READ_ANY_IMAGE and before OutputVideoCreator.  I could easily
add titles, etc. in Image_Viewer but as I sequence through the
HDF files, OutputVideoCreator was never updated.  The only way
to update OutputVideoCreator was to use 'Save Image' in Image_Viewer.
'Save Image' would have to be used once for every image in the
sequence.  This is not an acceptable solution.

Does anybody have any suggestions, help, etc.?

Thanks in advance,

Could anyone with any information on any project management
software available over the net please give me any info.

This is a wide brief, right now I am extremely interested in anything 
related to tools to assist in groups working in the analysis, design
or implementation stages of a project.

The software is necessary for a new course being set up here, and
we are interested in seeing whats available.

The course is hands on, and will probably lead to a team working 
on a C implementation.

We are interested in looking at an object-oriented approace, so
anything that helps here is also interesting.

So key words might be software management in its broadest sense, 
project management, Computer Aided Software Engineering and so on

platforms include dos, alpha/OSF, and linux ...

Please post all responses to this to me, and all followups to me 
(dave@odyssey.ucc.ie), I will post a summary of any responses I get
to the newsgroups ..

thanks in advance

p.s. I tried x-archie for manage, mgmnt,plan,project with no success

The input to the module is READ_ANY_IMAGE and another module that

There is a typein at the bottom of the geometry viewer window to set the size
of the geometry viewer ( and therefore the image). It's on the Cameras menu.
There is also a Show Camera just above the type in which hides the window
from the screen (saves a bit of time).

You can also do this via the CLI.  

Hope this helps

Since many of the specific file formats already have either their own
newsgroup or mailing list for in-depth discussion, there doesn't seem
to be a lot of merit to having a group where the discussions would
almost certainly bifurcate into the general classes...

HOWEVER, the idea of having a FAQ consisting of a lot of useful file
format FAQ summaries/pointers, and ftp-archive-for-sourcecode lists
does sound like a very good idea, indeed.

If *you* would like to edit the FAQ (don't look at *me* -- the
alt.comedy.firesgn-thtre FAQ's already eat up too much (all) of my time :-)
Here's a starter outline just to give you an idea of what you're
up against (and this is *just* a starter outline, no answers!)

This outline will also serve as an example for how *unwieldy* a
comp.file-formats group would get!

NB: I fully expect others will start adding on lots of other stuff
(not to mention providing the newsgroup/mailing list/ftp archive
 pointers, preferably in URL format for all those HTML browsers
out there (heh, heh--look 'em up). )

PS: Dont send the answers to Me !!!! I'm not touching this!

Greetings,

   I know that this is not proper material for the newsgroup, but these
are rare enough that it is uncertain how to proceed.

   I presently own a Stardent Vistra 800 machine with the entry-level
graphics adapter.  I realize that this is a discontinued hardware line,
and that Stardent transformed into a software company working with AVS
(and now called AVS).

   I am looking for three items from/for a Stardent Vistra:

     1)  either just the 24-bit true-color graphics adapter, or, in addition,
          the Stardent ARM (Advanced Rendering Module) that can be piggy-
          backed on the 24-bit adapter.  ..i.e. a graphics accelerator!
         (actually, I may be interested in two accelerators!)

     2)  A newer release of PEX/PHIGS than I currently have (although I
          suspect that I may be out of luck here).

     3)  4 MB SIMMs that work in a Vistra (I think these are 60ns static-
          column SIMMs), in sets of 8 SIMMs.  (I need 8 per bank).

   I am notably more interested in the former, especially the ARM, as it
improves graphics performance by a multiple of about 6 times or so.

   The PEX/PHIGS software as it is is nice, but there were several features
(like Data Mapping) that had manual pages but were unimplemented.  This, as
well as some others, leaves an itch to get them to work.  It would be
REALLY nice if I could somehow get hold of some source code...  but I realize
this is unlikely.

   If someone is willing to sell a whole Stardent Vistra with the full
graphics accelerator configuration in it, I will also be interested.
Anyway, it comes down to my being very interested in aquiring one.  I
know that several installations have them, and as they are a discontinued
product line, perhaps someone or some place is willing to part with it for
a reasonable price?

   I'm willing to deal, so let me know if you're looking to get rid of one
or might be willing to!

   Thanks for your time.

(sorry for the previous uncomplete posting. This is the right one)

I have some geometry files in a format called "3D Studio".
I heard that this may be connected to Autodesk Animator.
Has anyone information regarding how to read this files, internal format
or any translator to AVS-geom format ?
Any pointers will be appreciated.

Use field to ucd to convert the field into an  ucd structure, and ucd threshold 
to extract the appropriate elements. They can be displayed with ucd to geom the ucd
structure can be examined with ucd print.

Subject:    Image -> Postscript in AVS 4 ?
Lines: 21

Hello,

I have created some nice animations in AVS of the compressible flow and now
I would like to print some of the most interesting frames.  However, I would
like to have several (say 8) frames on the single sheet of paper. The modules
that exist for converting AVS images into postscript files can save only one
image per sheet and often blow up the image to full size therefore the printed
image is somehow "blocky" with evident loss in resolution. I have tried the
"write_to_postscript" module and other that comes with the AVS 4. None of them
can deliver quality output, unfortunately.

I'm looking for help in that matter.

I'm using AVS 4 on Kubota Pacific Stardent.

Thanks for any suggestions.

  I'm currently using the "image to postscript" on a Stardent with AVS 4,
given the right image and printer the results can be very stunning.  There are 
a few things to consider.  First you are generating a postscript image at the 
resoution of the screen (100 dpi) and not of the printer (300 dpi).  Thus the 
bigger the image is on the screen at the time you save to a postscript file 
the better it will appear when you print.  This is explained the best in the 
"User's Guide" at the end of the section on the geometry viewer.  Next for a 
grey scale image, at least for me, the toner tends to smear producing images 
that are dark and have bands or lines.  So try to use losts of "white" space.  
Or color! :)) I've just gained access to a Tecktronics 4511 color printer on 
our network.  The color is beautifull!  But beware these are huge files 
anywhere from 3 to 5 meg for me ( your milage may vary ).  Last check out the 
CLI commands.  It's possable to save images to postscript from the command 
line with an incress in resolution.

  As to putting several images on a page try one of following:

    Save the images in a form the AVS image viewer can read.  Then put 
    several scaled images in a single scene. You can even add text
    but don't look for a great selection of fonts. 

    Save the images as encapsulated postscript files and paste them into
    your favorite word processer etc.  This is great for vu-graphs.

Hope this helps and I would be interested to here what others do.

Hello

When I exit the network editor, it takes about 10-20 seconds until
the AVS main menu appears.  This is true on all platforms we have
independent of the compute or graphics power of the machines
(SGI, Sun, Convex).
Anybody knows what is going on?  Is it a configuration problem?

Thanks for any suggestions or help

I am having problems using the routine

	int CHEMatom_of_index( CHEMatom **root, int n);


The way I've used it in my program is as follows:

	CHEMmolecule *mol;
	CHEMatom *rootatom, *atom;
	CHEMcandb *cnb;
	int conn;
	double x,y,z;

	CHEMmolecule_get_atom(mol, &rootatom)
	CHEMatom_get_candb(rootatom, &cnb);
	:
	:
	CHEMcandb_get_conn(cnb, &conn);

	atom = CHEMatom_of_index(&rootatom, conn);
	CHEMatom_get_xyz(atom, &x, &y, &z);

This method seems to obtain the correct number of connections, 
however, the x,y,z locations of the connections are not always
correct.  I've checked the AVS Chemistry Developer's Guide but it was
not of much help.

If anyone can spot the problem or point me to an example program
which uses this routine, I'd much 'preciate it !

Nihar S. Gokhale (gokhale@amenhotep.mcs.anl.gov) recently posted about
a problem he was having with CHEMatom_of_index.  While I'm not sure,
looking at old code from my Stardent days suggests that the problem might
be one of indexing - internal indices are 0-based and external indices
are 1-based.  If it's an "off-by-1" error, and the structure's "typical"
the connectivity of adjacent atoms might be the same (thus masking the
error).

I suggest playing with the return of the function (with the debugger).

Also, there should be a chunk of chemistry demo code in the avs distribution
area... For more specific answers, contact Ed Bagdonas (epb@avs.com)

Hello folks,

This group is probably my best shot at finding Stardent GS users,
apologies to the rest of the group.

I have a few specific questions about part compatibility between
GS1000 and GS2000 systems.  If anyone has the experience to offer
answers, I'd appreciate some email.

I know about GS Services; is the old Stardent email list still around, or
achieved at an ftp site? 

Thanks.

In-reply-to: JHHARDE@erenj.com's message of Thu, 16 Sep 1993 21:48:46 GMT

	I've found that for producing collections of postscript, it's
much easier to use a package called the PBMPLUS package.  It doesn't
come with AVS, but it's freely available from a number of ftp sites
worldwide (use Archie to find the one nearest you.).  To create a
collection of 6 images on a page, I followed the following proceedure:

For each image I wanted to use, use xwd to create an x window dump of
the image on disk.

For each xwd file, run xwdtoppm to convert the xwd files into portable
pixmap files, which the pbmplus package can manipulate.  The best way
to do this is to use:
%>xwdtopnm <xwdfile> | pnmcrop | pnmmargin -white 50 > <file>.ppm

Then run pnmindex in the following way:
%>pnmindex -accross 2 <files>.ppm > index.ppm

The images are all pasted together, 2 images wide and 4 long.  The
pnmmargin command in the first pipeline is to make sure that there's
some space between the images on the sheet.  You may also want to pipe
the output of pnmindex through pnmmargin -white 50 to be sure that the
margins are adequate.

The result of this last step is a single, HUGE portable Pixmap file.
If your image window is 500 pixels by 500 pixels, the resulting PPM is
about 1200x2400 pixels.  If you then run: %>pnmtops -dpi x index.ppm
where x is the resolution of your printer, the index image will be
scaled appropraitely for the resolution of your printer.  When pnmtops
tells you what scale factor it's using, be sure the number is less
than one.  If it is not, the image is being enlarged and it'll apprear
blocky. The scaling algorithm is very good and I believe does
antialiasing for you, so the resulting images are as good as you'll be
able to get.

One last note: When I did this, I made sure that my individual images
were enormous, to be sure that they I gave pnmtops too much
information, so that I'd get the maximum resolution out of the
printer.  I think each of my images were 1200x1200, without the
margin.  The whole proccess took about an hour and a half, using a
local hard drive.

If any of this is confusing, please send me email and I'll try to
clarify.

Can anyone give me some advice about possible methods of visualising
Molecular dynamics type ouput in AVS5 (running on an SGI Indigo R4000 Elan)?
(68MB memory, similar swap space)


I have been playing with some of the chemistry modules with mixed results.
It would seem that Read Structure file (reads in .con files) has a limit
to how many atoms are read in (a 1-2 hundred?). It also complains (not every
time) about some error with symmetry. I also get frequent freezing of AVS.
I have looked at the Chemistry manual but to be quite frank it is not
talking to me at all.

What I am after is a way of viewing 'atoms' scattered in a box, with the number
and positions of atoms changing with each timestep. Total number of atoms
varies from  one to a few thousand. The atoms do not form a molecule so I do
not want sticks drawn between them, (although this has worked quite well
for forming the edges of a box, 8 'dummy atoms' at the corners).
So far I have only managed to look at single frames with what I call a few
atoms (spheres whatever) so even if I could improve this to single timeframes
with any number (say upto 2000 or within memory bounds) I would be chuffed.

Perhaps using bubbleviz would be a better route? Perhaps there is module to do
this out there? Please note that I am using an SGI system so if you point
me towards libraries of SUN, HP and IBM modules ..... well I have no idea
how to convert these to work on an SGI Indigo (running IRIX 4.05f).

I know this sounds as if I am being lazy but I have been playing with this
for weeks off and on. I thought I had it cracked but.... well parts of
the computer are about to take flying lessons. 

Thanx.

Andy Calder.

Michael,

AVS' sometimes seems to be TOO flexible and things that you'd think 
should be easy to do seem confusing until you get into the "AVS 
Gestalt" - a mindset where all is clear and the logic underlying 
the apparently bizarre contrivences is laid out and understandable.  
When I get there - I'll let you know...

Until then, here is a field file demonstrating how to read in a matrix
of integers and a network file showing how to use it to create a 
colored image.  Save the field file as test.fld, the network file as
test.net, and then read the network file in.

Good luck and let us know how it works out!

Hello,

I have one coroutine module M which can not be read into 'Module 
Palette'. Module M is a local module and is compiled okay. In the 
network editor, I can read any other subroutine modules that are
written by myself. 

Module M is readable at the beginning and works fine. But, it can 
not be read after I pull it out from network at run time. I try to
modify the program, recompile it, and read it again. However, it 
still doesn't work. Any suggestion?! Thanks for your help.

Frank

I don't think than any current supported AVS module can help you in this
regurd. What I think you need is a kind of time-based simulation coroutine
that will feed the atom geometry into the geometry viewer and will control
their position and visibility through calls to the geom_* routines.

As far as I understand even the AVS/Animator module is not suitable for
this purpose, since it is frame based and not time based.

We have created such a coroutine module, called "time_anim", but right now
it is too hooked to the application to be usefull for you (we do plan to
clean it up in the near future and submit it to the AVS center). what we
done was to get a stream of position and rotation vectors as a function of
time and change the transformation matrix in the geomlist by calling
GEOM_edit_set_matrix.

The tricks were to initilize the geomlist in each time step so it won't repeat
all the previous steps every time, and to update the scene once for all the
bodies in each time step. In a medium performance machine (DECstation/PXG)
we succeeded in moving several handreds of spheres and about a thousand
"boxes" in a reasonable rate (several frames per second, it was quiet smooth).

If all you need is quasi-dynamic, by controlling manualy the time steps
then all you need is to create a lot of atoms from the (suggested) same
geom sphere files, give each object at creation a distinct name (counter)
and control the position of each by modifying the matrix in geometry
list. Since the transformation matrix structure is not well documented
I am posting at the end of this message a code fragment (in fortran ...).


Good luck

Here is a very simple method to animate time dependent molecular 
dynamics data.

Put all your time steps in a file.

Read the data as a 2D scatter field (this would be a "2D 1-vector 
3-coordinate irregular field") using read field module. You can use radii for
the scalar value at each coordinate.

Use orthogonal slicer to slice along the time axis. (You have to use
Wes Bethel's "new ortho slicer" module from IAC since orthogonal slicer 
module does not slice scatter data correctly.)
I call this technique "time axis orthogonal slicing".

Scatter dots and geometry viewer module to display the atoms.

Then animated integer module to animate along the time axis to see
the animation. 

(You are not going to have much luck with the speed on your indigo without 
hardware spheres.)

This is the most convenient method.  There is module called read macatom3D
that read MacAtom format data which you can use. And we also have a suite of
functions and modules under development using HDF (DFMD data type) for such 
animations.

I wish I had more time go into details.

	(217) 244-2909 (fax)

Workshop Description:

As the use of visualization increases, education about the field 
becomes more and more important.  In this full day workshop, we 
will discuss approaches to formal and informal education in 
visualization.  Teaching visualization is challenging because of 
the breadth of topic, the multi-disciplinary nature of the area, the 
mixed backgrounds of potential student audiences, and the relative 
scarcity of the types of instructional resources that are usually 
available for more well-established areas.  This workshop presents 
an opportunity for participants to share their solutions to these 
problems, discuss related issues, and learn what their counterparts 
are doing in the area of visualization education.  The primary goal 
of the workshop is information exchange among a diverse group 
of providers of visualization education.

The workshop will address the following issues:
% What are the essential topics to teach about visualization?
% Who are the target audiences for visualization education?  
Researchers and students? Disciplines?
% What are different strategies for developing expertise in 
visualization? Topics or Project Emphasis?
% What are the tradeoffs among different strategies?
% What resources are available for visualization education?
% What hardware, software, output are necessary to support 
visualization education?

Workshop Description:

Visualization is a powerful method for performing data analysis in 
many disciplines, and like other data analysis tasks requires 
different levels of decision-making processes. These decision-
making processes require knowledge and experience from 
interdisciplinary areas such as data and visual representation, as 
well as knowledge  of the functional characteristics of data 
manipulation and visualization procedures, and software packages 
that perform these procedures. Due to the heavy knowledge 
requirements of current visualization systems, data analysis has 
required a level of expertise that exceeds the qualifications of 
ordinary data analysts or scientists.  Ideally, a visualization 
analysis scenario must go through the steps of relevant data search 
and retrieval, acquistion of user's task requirements, and then 
production of useful data display plans or designs.  The three 
fundamental areas that visualization systems inadequately handle 
are: (1) Data Access, (2) Task Understanding, and (3) Visualization 
Design processes. The design of  visualization systems that 
intelligently handle these three issues is the focus of this one day 
workshop.



Workshop 3 (Full Day)
Tuesday, 8:30 am - 5:00 pm

Workshop Description:

This workshop will bring together researchers from a number of 
fields to share work on supporting the human decision maker under 
conditions of less than perfect knowledge and less than perfect 
criteria for a decision.  Its primary focus will be on visualization 
methods that support this process.  The emphasis will be on visual 
representations of problem sets that facilitate the perception of 
patterns, relations, and exceptions in the representation itself. 
Statistical or AI heuristic methods that present results in novel 
graphic form will be considered.  


Workshop 4 (Full Day)
Tuesday, 8:30 am - 5:00 pm

	(508) 452-4298

Workshop Description:

Data Visualization deals with the effective portrayal of data with a 
goal towards insight about the data. Typically, the data is of high 
volume,  multidimensional in nature, and does not lend itself to 
easy display. The data is also often spatial and temporal in nature. 

Database issues for data visualization have become increasingly important as
ever-larger data set sizes and dimensionality create problems that present-day 
systems cannot handle. Collaborative computing requires multiple users
accessing multiple, heterogeneous databases. To explore relationships between
many data variables, researchers must be able to query data in meaningful
ways. Currently, visualization system users are only given minimal querying
support, limited in most cases to interaction with output data represent-
ations, or single-valued data probes. This workshop intends to deal with
issues specifically related to the integration of database management sys-
tems with data visualization in hopes of determining methods for supplying
end users with the data interaction support they require, and overcoming
performance impediments related to the integration.

Tutorial 7
Tuesday, 8:30 am - 5:00 pm
Visualizing Statistical Data
Instructor:
W.S. Cleveland, AT&T Bell Labs

Course Description:
There are two components to visualizing the structure of 
statistical data - graphing and fitting. Just graphing raw data - 
without fitting mathematical structures to them and without 
graphing the fits and residual - often leaves important aspects 
of the data undiscovered. This full day tutorial presents 
methods for graphing and fitting. The material is organized 
around applications of the visualization methods to data from 
scientific studies.

Who Should Attend:
This tutorial and the book on which it is based, Visualizing Data,
are meant for those who analyze statistical data. A knowledge of
very basic statistics is suggested although much of the tutorial 
does not require it.

Instructor:
William S. Cleveland is a member of the Mathematics 
Research Center at AT&T Bell Laboratories. 



Tutorial 8

Visualization '93 Special Sessions:


Date and Times to be announced

1.	Panel: Data Visualization: Research Issues,
	Applications, and Future Directions

Vis'93 presents a panel of visualization experts as a special
evening session. These panel members participated in a Office of
Naval Research Workshop on State of the Art in Data
Visualization in Darmstadt, Germany.  This Special Session will
report the major findings of the workshop to you and continue the
lively discussion from that workshop.

Panel Chair: Rae A. Earnshaw,University of Leeds, UK

Panelists:
Steve Bryson, CSC/NASA Ames, USA
Jose L. Encarnacao, TH Darmstadt, FRG
Hans Hagen, University of Kaiserslautern, FRG
Lambertus Hesselink, Stanford University, USA



2.	Workshop Findings:

The Workshop Organizers, participants and the Workshop Co-
Chairs will discuss and review the results of the Monday and
Tuesday workshops on Visualization Education, Intelligent
Visualization Systems, Visualization in Decision-Support, and
Database Issues for Data Visualization. This session is open to
all workshop, tutorial, symposia, and conference attendees.



3.	Research Problems in Visualization 

This is an informal meeting to provide attendees the 
new problems collected over the past year, discuss 
results on any of the 1991-2 research problems, or 
to present new research questions to be included in 
the 1993 research problem set.  These problems will 
be published in the IEEE Technical Committee on 
Computer Graphics Newsletter. Presenters should 
send their one page descriptions of results or the 
new research problem to grinstein@cs.ulowell.edu 
by October 10, 1993.




4.	How to Lie and Confuse with Visualization
    
People have lied with statistics and maps for 
years.  Now it's time to look into lying and confusing 
in the field of visualization.  Your once-a-year big 
chance to do just that, in the open, will be in this 
special session on Tuesday, October 26, 1993 at 7:00 
pm.  You are invited to bring with you visualization 
lies and confusing articles, yours or others, on 35 
mm slides or video.  During this evening, it will be 
allowed to lie but not to borrow credit, so please do 
not forget to mention the producers' names.  After 
the informal presentations and truthful debates, the 
audience will choose the biggest (visualization) lie 
for 1993.  When the evening is over, lying will be 
outlawed again.  Then, we will be all able to benefit 
from this teaching of what it takes to produce 
realistic and faithful visualizations.

    Reservations and advance submissions are now 
being accepted (c/o Nahum Gershon, The MITRE 
Corporation, 7525 Colshire Drive, McLean, VA 
22102).  Both are not required but are strongly 
recommended.  For more information    (genuine!), 
please contact gershon@mitre.org.

great opportunity to be a part of the cutting edge in computer graphics
and data visualization. 

The conference is relatively small (up to 500 attendees), and will
draw on noted researchers in a number of disciplines. There are plenty
of opportunities to interact with the best and most prominent people
in the field !!!

This year's Visualization Conference will include papers on all aspects of
scientific data visualization, as well as symposia on Virtual Reality
and Parallel Rendering, Case Studies of Visualization techniques and
applications, and demonstrations of state-of-the-art hardware and
software products. Complete conference information can be found via 
anonymous ftp to ftp.uml.edu, in the "vis93" directory.

		^_________________________________
this may be your problem... I couldn't get this "library" routine
to work correctly on the GS architecture.  I violated the dev. kit 
advice (since I _had_ spent 2+ hrs playing with my non-functioning
module and get_xyz) and did this instead:

      current = (CHEMatom *) CHEMatom_of_index(&atom_head,j+1);
      coord[j][0]=current->x; coord[j][1]=current->y; coord[j][2]=current->z;

hope this is useful.

You may want to check your library to make sure it isn't pointing to
something bogus. Another quick check is to trash the module directly
from the library area to the hammer before dropping it in the network
editor, and then reading in the module in from where you know you just
built it.

just a suggestion,

Hello!!

I was happy, to found ucd_extract_new. I got it, install it, all very
fine. It is working too, but not in the way, I hope.
If have ucd-structure with e.q. 10 scalar values at each node.
The description of the ucd_extract_new modul I understood in this way,
that, if I connect it with animated integer, the modul will extract
first scalar 1 for all nodes, then scalar 2 and so on.
But it does'nt do this!! 10 times the button of scalar 1 at ucd contour
is blipping, but it changes not to scalar 2, 3 and so on!!
Is it my failure or is perhaps something wrong with the module???
(I tried it under AVS 5 on an IBM/RISC 6000)

Thanx for any help, regards
Astrid Kuhr

Hi there.

The University of Oslo is planning to set up a small lab for data 
visualisation. Here we hope to view different kinds of data 
graphically and capture it on video. This is a pilot project which 
should point out what we can do at affordable prices. So far we know 
we are going to use both AVS and SGI's Explorer, and at present we 
have an Indigo 2 with a Galileo Video 24 bit graphics card at our 
disposal. We have not yet decided on the way we are going to capture 
the output onto video.

What we would like is some input from the net, primarily about getting 
it out on video, and also about data visualisation in general. 

Are there video solutions that are better than others, but still in 
the lower price range? What are the viable alternatives?

Our main problem is finding a relatively cheap way of getting a slow 
"once a second if we're lucky, but don't count on it" animation speeded 
up to an acceptable number of frames per second on video.

Are there any labs out there in a similar situation that perhaps have
come a bit further and have gained some experience they can share with us?

We'd also like to get in touch with other labs for possible further 
exchange of information and experiences, so do not hesitate to drop 
us a line and tell us a bit about what you are doing. We hope to also
have contact with labs that are aiming higher than we are currently
doing. Should this pilot project be a success and there is a market for 
it here, we are definitely interested in going further.

Hope to hear from many of you!

Followup is set to my email address (hope that is possible :-) as this
posting is crossposted to several newsgroups.

Greetings, is there a module which filters a string to return a "sub-string"?
For example, I want to extract the sub-string "NGM" from the string 
"latest_NGM00.fld".  What module does this, if any?

well as a workshop, tutorial or symposia of their choice. This is a 
great opportunity to be a part of the cutting edge in computer graphics
and data visualization. 

The conference is relatively small (up to 500 attendees), and will
draw on noted researchers in a number of disciplines. There are plenty
of opportunities to interact with the best and most prominent people
in the field !!!

This year's Visualization Conference will include papers on all aspects of
scientific data visualization, as well as symposia on Virtual Reality
and Parallel Rendering, Case Studies of Visualization techniques and
applications, and demonstrations of state-of-the-art hardware and
software products. Complete conference information can be found via 
anonymous ftp to ftp.uml.edu, in the "vis93" directory.

Ported to   : IBM Convex Kubota Sun HP
Description : CROP2 crops 2-D fields by selecting a window of the input
              field. It differs from CROP in two ways. The more obvious
              difference is that the output field is defined by the
              position of a centre pixel, and a field width. The limits of
              the parameters are interdependent, and so are updated
              according to the current selections. The other reason for
              the creation of this module is that CROP limits the minimum
              dimension to 2. This is unacceptable when a 2-D field is
              required having one dimension set to 1. (ORTHOGONAL SLICER
              will produce the correct data, but reduces the
              dimensionality of the output field, which makes it
              unacceptable as input to many modules.)

              pipe, with options to flush, etc. It outputs the full

              modules to use for the communication.

              pixel values in the range 1 to n where n is the number of
              distinguishable categories of pixels. Such images arise
              from multispectral classification operations. COLOR
              PALETTE creates a colormap in which the hue values are
              equally spaced, and an amount of "jitter" may be introduced
              to the saturation and value in order to improve the
              differentiation of similar hues. The saturation
              alternates between 1. and 1. - satn_jitter. The value is
              successively 1., 1. - val_jitter/2, 1. - val_jitter.

Ported to   : Convex Kubota Sun HP
Description : This module navigates a menu structure which can be
              designed and configured by the user. Each menu level is
              described by a single ASCII text file. A menu level contains
              several buttons with user-configurable names. Each
              button results in one of three basic kinds of action in the
              module - (1) load a new menu level (2) pass a command to
              downstream modules (3) go to a file to find a series of
              commands to be passed to down stream modules. Option 3
              allows multiple commands to be played in background as the
              result of a single button press. The file containing the
              commands to be played in background is the second type of
              file associated with this system. Thus there are two types
              of file - (1) the MENU FILE to define a menu level (2) the
              AUTOMATIC FILE which contains a series of commands to be
              executed

Ported to   : IBM Sun HP
Description : The ChairPlot module is another alternative way of
              visualizing 3D volume data. The volume is displayed with 3
              orthogonal slice planes, with the exterior boundary
              filled in behind, so it looks like a section has been removed
              from a corner of the volume. It is similar to excavate brick,
              except that it makes 2D polygons, with UV texture
              coordinates and resamples the input data into 2D images
              that glue onto the slice sections. This way, 2D texture map
              facilities are used, rather than 3D texture. Several
              hardware vendors, notably E&S, SGI, Kubota, Vistra, etc.,
              have hardware support for this type of texture mapping. The
              software renderer also has support for this mode, where no
              accelerator is available. The controls are virtually
              identical to excavate brick.

students will be permitted to attend papers and panel sessions, as
well as a workshop, tutorial or symposia of their choice. This is a 
great opportunity to be a part of the cutting edge in computer graphics
and data visualization. 

The conference is relatively small (up to 500 attendees), and will
draw on noted researchers in a number of disciplines. There are plenty
of opportunities to interact with the best and most prominent people
in the field !!!

This year's Visualization Conference will include papers on all aspects of
scientific data visualization, as well as symposia on Virtual Reality
and Parallel Rendering, Case Studies of Visualization techniques and
applications, and demonstrations of state-of-the-art hardware and
software products. Complete conference information can be found via 
anonymous ftp to ftp.uml.edu, in the "vis93" directory.

Module path : avs.ncsc.org:avs_modules/filters/crop2
Ported to   : IBM Convex Kubota Sun HP
Description : CROP2 crops 2-D fields by selecting a window of the input
              field. It differs from CROP in two ways. The more obvious
              difference is that the output field is defined by the
              position of a centre pixel, and a field width. The limits of
              the parameters are interdependent, and so are updated
              according to the current selections. The other reason for
              the creation of this module is that CROP limits the minimum
              dimension to 2. This is unacceptable when a 2-D field is
              required having one dimension set to 1. (ORTHOGONAL SLICER
              will produce the correct data, but reduces the
              dimensionality of the output field, which makes it
              unacceptable as input to many modules.)

Description : This module creates and sets up a unix pipe file, for
              communication between an AVS module and an external
              application. It makes unix system calls to create the pipe
              file, based on a typein name. It helps manage the use of the
              pipe, with options to flush, etc. It outputs the full
              pathname of the pipe, once established, for downstream
              modules to use for the communication.

Description : COLOR PALETTE is used to create a colormap suitable for the
              display of "label" images, ie scalar fields containing
              pixel values in the range 1 to n where n is the number of
              distinguishable categories of pixels. Such images arise
              from multispectral classification operations. COLOR
              PALETTE creates a colormap in which the hue values are
              equally spaced, and an amount of "jitter" may be introduced
              to the saturation and value in order to improve the
              differentiation of similar hues. The saturation
              alternates between 1. and 1. - satn_jitter. The value is
              successively 1., 1. - val_jitter/2, 1. - val_jitter.

Description : This module navigates a menu structure which can be
              designed and configured by the user. Each menu level is
              described by a single ASCII text file. A menu level contains
              several buttons with user-configurable names. Each
              button results in one of three basic kinds of action in the
              module - (1) load a new menu level (2) pass a command to
              downstream modules (3) go to a file to find a series of
              commands to be passed to down stream modules. Option 3
              allows multiple commands to be played in background as the
              result of a single button press. The file containing the
              commands to be played in background is the second type of
              file associated with this system. Thus there are two types
              of file - (1) the MENU FILE to define a menu level (2) the
              AUTOMATIC FILE which contains a series of commands to be
              executed

Ported to   : IBM Sun HP
Description : The ChairPlot module is another alternative way of
              visualizing 3D volume data. The volume is displayed with 3
              orthogonal slice planes, with the exterior boundary
              filled in behind, so it looks like a section has been removed
              from a corner of the volume. It is similar to excavate brick,
              except that it makes 2D polygons, with UV texture
              coordinates and resamples the input data into 2D images
              that glue onto the slice sections. This way, 2D texture map
              facilities are used, rather than 3D texture. Several
              hardware vendors, notably E&S, SGI, Kubota, Vistra, etc.,
              have hardware support for this type of texture mapping. The
              software renderer also has support for this mode, where no
              accelerator is available. The controls are virtually
              identical to excavate brick.

                       N.E. 6th St. & 112th Ave. N.E.
                       Bellevue, Washington
                       October 5,6, & 7, 1993


The Washington Technology Access ( WTA ) center, in conjunction with the Human
Interface Technology  laboratory on th University of Washington campus,
and the Virtual Worlds Society cordially invites you to attend the first
Virtual Reality-Virtual Freedom conference to be held October 5,6 & 7,
1993. We encourage to actively participate in the first  WTA conference in
virtual reality and special need technology.


The goal of this conference is to bring together individuals with
disabilities, and researchers & developers in the many diverse technical
disciplines contributing to both the VR and assistive technology fields,
and provide a forum for the interchange of timely/quality ideas,
experimental results, and technical developments.


Virtual Reality has grown in recent years into an active,interdisciplinary 
field of research, development, and applications prototyping. It  goes by
several names including virtual environments, virtual worlds, artificial
reality, and advanced human-computer interfaces. Whatever it is called,
there exist many challenges to overcome in science, engineering, and
research; and have it applied to the field of assistive technology and to
those individuals who will benefit from this development.


Presentations will examine current research and development in the field
VR and how this new technology can be, and is presently being adapted and
applied to persons with special needs in the world community. (The term
"special needs" includes physical, learning, attention, sensory,
cognitive, and communicative impairment that a person might experience at
any age.


The Meydenbauer center, an accessible, multi-purpose event facility
located in downtown Bellevue, Washington will be the sight for the annual
Virtual Reality-Virtual Freedom conference. This facility also has the
capability for satellite uplink transmission of the conference proceedings
to remote locations which are currently being negotiated. The conference
is being heavily advertised on radio, electronic networks, and in the
newspapers and newsletters.


Information and development from this event will be utilized at the WTA
center's  research and development group where individuals with disabilities
will learn from and test virtual reality technology equipment. The WTA
research and development group will continue to explore and investigate
hoe new technology can be applied and intergrated into the lives of all
individuals.

Hello!

I want to visualize 1D field data.
Means, I have data with 3 coordinates (x, y, z) and 1 variable.
The data is irregular.
This I want to visualize, e.g. that I have a box at the screen with
a surface, which represents the data of the variable at each point
x-y-z.
How can I do this??

Thanx and regards,
Astrid Kuhr

I found that none of the "core" modules really handled this very well
at all.  Certainly you should avoid the "Chemistry" modules.

I wrote modules to do just this visualization, which are all available
from the IAC.  "Fast Animate" reads in a numbered sequence of ".geom"
files and animates them to the screen.  These can be any kind of
geometry at all.

You can create the geometries using "shak_to_geom", an offline filter
version of my "read_shak" module which comes as part of its distribution
at the IAC.  It will do exactly what you are looking for and you can
wrap it up in a shell script to generate thousands of geometries
automatically.  Or you may be able to use "pdb_to_geom" which comes
as standard with AVS.  But "Shal_to_geom" definitely has options
for getting rid of the bonds.

Hope this helps

I don't know if this is the proper forum for the following request but 
this group seems to be my best bet for a solution to a problem I'm having 
with my Vistra 800b workstation.

The Vistra's eathernet `card' is on it's last legs.  It's having severe 
intermittent power loss troubles.  When it's down I'm gettting a lot 
of : "LAN : 82596 board 0 No carrier" messages, and when it's working, I 
get a tremendous amount of collisions.  To repair this problem, the `card'
must be replaced.  Upon further investigation though, we discovered 
the eathernet `card' is part of the motherboard.  No matter how you look
at it, this can be a very costly fix for a virtually nonexistent machine.

I was hoping someone out there might know of a neglected Vistra machine
that could be `pieced out' or scavenged.  Any information and/or suggestions 
will be greatly appreciated.

Sincerely,

Can anyone help me with a `-postpend/-unpend' problem? 

It seems when I `-postpend' a filter module (or a module with an output 
port), it is easily `-unpend'ed.  On the other hand, when I `-postpend' 
an output module (or a module with no output port) and I try to `-unpend' 
it, AVS crashes.

The following is an exact script of the CLI commands entered and the fatal
error messages when I attempt to `-unpend' the `write field' module from the 
`read field' module.  As you can see the `-postpend/-unpend' operation on
the `downsize' module works just fine.  Is this normal?

Is there an undocumented CLI command which will `port_disconnect' all
connections to a module by just giving the module name and port.  For 
example is there something like : "CUT foo:0", which will disconnect all
connections to port 0 of the foo module.  This would be pretty darn 
helpful!

Thanks for any help you can give me!

We recently needed to do this too, we were able to work around the
fact that hedgehog wants a 3D field by just adding in a fake 3rd
dimension.  Just make sure that this dimension has vector values
of 0 and coordinate values of 0.

Using the file descriptor, select the number of dimensions to be 3,
rather than 2, the same goes for the physical space. Then, set 
the value for dimension3 to 1.  Parse the data for vectors 1 and 2
as usual and then do user-defined values of 0 for component 3.

We did this with a rectilinear 2-d orignal data set and were pleased
to see hedgehog happily draw 2-d arrows.  Be advised that this fake
3D field may not work well with some other AVS modules, expecially
ortho slicer.  I can dig up a sample data form if it would help...

If I use one module twice in a network, it is difficult to distinguish

I've had a similar problem - what system are you using? I'm using
an HP, and have been porting my avs modules to many different platforms.
I've found that if you use AVScreate_float_parameter and don't explicitly
put the arguements as FP numbers (ie append .0 to anything that happens to
be integer) then it assumes that they ARE integers and compiles as such.

Naturally it is good programming practice to do this anyway, but this was
my problem. Funny... it worked O.K. on the HP, but not on anything else
that I tried.

Hope this helps,

Chris Beauchamp

There is a module at the FTP site (I don't remember it off hand) that
converts a 2d field to a 3d field (with a third dimension that exists, but
is only 'imaginary').  This will allow you to use the modules that can
only be used for 3d fields (i.e. hedgehog).  You can add the module to
the 'submitted' Library.

Or how about using Phil McDonald's show_flow module
from the IAC, which takes 2D vector data just fine (as well as 1D and
3D).  It has lots of other great features, too -- so many, in fact, that
I *never* use hedgehog!.

Hi folks-

  Sorry if this is a FAQ, but I've checked on here a couple of times and haven't
seen it.  

   I have ascii x,y,z data that I have read in as a 3D irregular field.  I want
to display it as a 3-dimensional shape that can be rotated etc in the geometry
viewer, only it resists becoming a geometry.  I can get the graph viewer to
display the contours of the bathymetry correctly.  I've tried "field to mesh" 
and "contour to geom" and haven't had any success getting what I expect as
an output geometry.  None of the examples I found did quite the right thing. 
I put "extract scalar" in there, and that allows the network to go, but the
output to the geometry viewer isn't what I expect.

   Any hints or solutions will be greatly appreciated, and again, sorry if this
has often been addressed before.

I would like to thank those who responded to my question. 

These are my summary:

1. Use a 3-d filed instead of 2-d field and use hedgehog module. 

2. Use show_flow module from avs.ncsc.org

Description : uv_sector - Create a mesh over a sector of an annulus.
              UV_SECTOR generates a geometry which is a sector of a
              circular annulus, with UV coordinates> The geometry of the
              mesh is determined by the input parameters. The Resolution
              parameter determines the number of mesh nodes in both
              directions. The UV coordinates are set from 0,0 to 1,1 over
              the extremities of the mesh. The purpose of the module is to
              demonstrate the ability to warp an image (eg cartographic
              dataa) by texture mapping it to a geometry whose shape can be
              varied.

Description : This module takes an input field, such as a 1D n-vector
              uniform field, and interactively decide which "column" or
              channel should be used for each of X, Y, and Z coordinates of a
              scatter field. Any remaining quantities, if the field had
              more than 3-vectors, are placed on the output field as an n-3
              vector field. This can be used to create multidimensional
              scatter plots, showing channel correlation by spatial
              clustering. It is much easier to import uniform fields
              using read_field or the ADIA, then use this module to create
              a scatter, than to define a scatter based on the external
              file format. This module will work with byte, float, int,
              double, or short data types.

Description : This is a UCD filter to extrude 2D triangle UCD's to 3D
              prisms. Given triangular 2D UCD elements and a 2D field,
              loft the elements into 3D prism elements, with information
              for the 3rd dimension coming from a 2D field, where the first
              dimension matches the input UCD node list, the second
              dimension replicates the structure, adding a Z offset and
              new data. The control field contains all information to
              create the structure, both coordinates and data, except
              for cell topology, which comes from the input 2D ucd. This is
              intended to be generated by a module like scat_to_tri
              (delaunay triangulation). Each "row" of the input field
              represents one 2D surface, where the 4-vector information
              is - 1) X-Loc, 2) Y-Loc, 3) Time (depth), and 4) Velocity. The
              X-Y pairs are un-ordered, and represent random surface
              positions.

Description : This is a UCD filter to convert node data, component lists,
              node id's to AVS field and string structures for external
              processing. The data on the nodes of the UCD model are
              brought out to a floating field port, where the data can be
              further processed such as with extract scalar, field math,
              or statistics, or sent to a graph viewer. The difference
              between the nodal values on two different UCD structures
              could be computed, for instance. In "irregular" mode, the
              output value field is in "scatter" form, so spheres can be
              placed at node positions with bubbleviz and scatter dots.
              In addition, the node id's are converted to an integer
              field, and the component list is converted to and integer
              field, with component names and units converted to string
              output ports. This is very handy for debugging UCD
              applications, for processing UCD data using field
              modules, or other user written modules. Note that this is
              not the compliment of field_to_ucd, as this is
              topologicall y impossible.

              hairs are pickable, and change colour. The node number and
              x-y coordinate value of the picked node is shown and can be
              controlled with the an integer typein, and are output on one
              integer and two float output ports. This can be used to
              control modules that use position dials, perhaps to create
              a cutting sheet or a graph plot of the selected data section.
              Downsize control allows a subset of node positions to be

Ported to   : Sun HP
Description : This is a display module, it takes a 2D floating point field,
              treats each row as a 1D signal, and draws the signal traces
              next to each other. The offset, amplitude, signal spacing,
              etc. can be controlled for any range of data. The signals can
              be plotted vertically, horizontally, or in 180 degree
              polar configurations. Additional controls allow for
              Seismic moveout interpretation, given an Time Offset (T0)
              and a Velocity, linear or hyperbolic moveout functions may
              be overlayed and optionally applied to the trace data. The
              display is like wiggle trace, but the areas under the curve
              are not filled in. The module catches mouse events in the
              window, but these are currently commented out. One
              possibility is to provide dynamic pan and zoom under mouse
              control, or allow signal picking. If the input is 1D only, it
              will draw one signal line, and may be used like a real-time
              oscilliscope display.

Ported to   : IBM Convex Sun HP
Description : sysModuleName - given the alias name of any module in the
              network this utility outputs the system's name for the
              module. This will return the system name for the module when
              its alias is typed into the parameter. For example if you use
              AVS CLI - "avs> module "geometry_viewer" -alias geomV",
              the system might name the instance of the geometry viewer as
              "geometry viewer".user.17. The module can be referenced
              by this name or by its alias "geomV" for most purposes, but
              some commands will only accept the system name. This module
              will get the system name from the alias which makes an
              application more robust. Thus in the example, if "geomV" is
              entered into the parameter, "geometry viewer".user.17 is
              output from the module.

Module path : avs.ncsc.org:avs_modules/filters/scat_to_tri
Ported to   : Convex Kubota Sun HP
Description : This is a 2D grid generation routine, that takes random
              scatter data in a plane, and creates a delaunay
              triangulation from them. It sends node position data and
              connectivity information out via a UCD structure,
              containing only the 2D elements. It only grids based on the X
              and Y coordinates of the input data, but preserves the Z
              values on the UCD, so irregular 3D sheets may be generated.
              The core algorithm is from a public domain library for
              voronoi and delaunay triangulation at "netlib", called
              "sweep2". The only modifications to the package from
              netlib is the re-write of "main.c" and "output.c" to create
              AVS coroutine structures, and to pass data from shared
              memory rather than file I/O. All data stored at each point in
              the input field is transfered unchanged to the UCD, for
              further interpretation or processing.

Module path : avs.ncsc.org:avs_modules/data_input/Read_EJ65
Ported to   : HP
Description : The EJ65 file format interface is for 3D body fitted
              coordinate flowfield and mesh data. This module is a Reader
              for the EJ65 geometry and field data, in FORTRAN. It
              accesses the files via interactive browsers, and reads the
              binary files directly into the AVS session. The two
              browsers are for the mesh and flow field files. They are
              combined on one output port. The module is automatic, and
              follow the input array dimensions, but must be compiled
              with an interal array size to match the largest expected
              field. Two types of input are supported, native floating
              point format of the host machine (double precision), and if
              the host is bigendian, then native CONVEX non-IEEE binary
              input is supported, using the optional mode. By default,
              the flow solution data is moved 1/2 a cell to the node
              positions. If requested, it is left at the cell centers, and
              nodal values are calculated by nearest cell
              interpolation. The interpolation mode is untested. The
              Freeze button us used to set new flow or mesh files, or other
              parameters on the module, before attempting the read. Both
              files are accessed, regardless of the parameter change.
              The EJ65 file format is in use at a number of sites, including
              British Aerospace, PLC, UK

Module path : avs.ncsc.org:avs_modules/mappers/Polyline
Ported to   : IBM Sun HP
Description : The polyline module interacts with the AVS5 image viewer,
              to allow interactive line drawing on top of an image. Points
              inside the image can be picked, and line segments are drawn
              with "rubber banding" along the pick sequence. "Undo" will
              back up the line segments, and clear will erase all lines. If
              multiple image viewer "views" are open, the rubber banding
              can be seen in each window at the same time. The resulting
              picked polyline list is output on a scatter field port, for
              external processing by other modules.

Description : The plumb_line module annotates the top surface of an
              irregular 3D field, with red cross hairs over each node. The
              cross hairs are pickable, and drive a line along the
              remaining axis, through the 3D space. The (I,J) index for
              the picked point is shown and can be controlled with the X-Y
              integer dials, and are output on two integer output ports.
              This can be used to control modules such as "orthogonal
              slicer" to create a cutting sheet or a graph plot of the
              selected data section. The picked cross hair changes color
              to white, and a polyline following the mesh is drawn below.

Module path : avs.ncsc.org:avs_modules/data_input/Mouse_Trap
Ported to   : HP
Description : The "Mouse Trap" module accesses the X-Window of the
              Geometry Viewer display, and changes the mouse button
              definitions. It is intended as an AVS application
              developers example, to create custom interface controls.
              It intercepts all mouse events, and then selectively sends
              commands on to AVS for action. At present, it ignores all
              except the right mouse button, which behaves as a "pick",
              like the normal AVS left mouse button, while ignoring
              rotation and translation requests. The implementation is
              to make an invisible input only window, exactly covering
              the geometry viewer window. Events from this invisible
              window are detected, masking the geometry viewer window
              native events. Commands are then sent via the CLI
              mechanism. As a coroutine, this module can also take events
              from user interface parameters, although none are present
              in this version.

              a polyline structure, so it can be used with cylinder or
              tube, to create solid arrows. The cone is sent on one geom
              output port, while the original polyline is sent on the
              second port, such that it may be sent to cylinder. Min and Max
              controls allow lines of only certain bounded length to have
              cones, shorter or longer lines do not get cones.

Ported to   : IBM Kubota
Description : LOCAL AREA STATS is an image processing module, similar to
              LOCAL AREA OPS, but including other measurements. For all
              choices, the pixel value is replaced by the appropriate
              statistical measurement of the local area around it, as
              determined by the kernel width parameter. The most useful
              measurement provided by this module is the standard
              deviation, which can be used to create adaptive
              thresholding fields. Skewness and Kurtosis are defined in
              the information for STATISTICS which calculates the
              global values of these parameters over an entire field. The
              kernel width is constrained to be an odd number, so that it
              can be centred on a pixel. The data type of the output field is
              the same as the input field in the cases of min, max, mean and
              median, but is always of float type for std dev, skewness and
              kurtosis.

Ported to   : IBM Convex Kubota Sun HP
Description : Jigsaw creates a simple geometric object of extruded

              AVS field controls the height, color, or visibility of each
              block. This module is similar to "Read Blokjes" at the IAC.
              Some degree of concave outline structure is allowed. Each
              piece has a unique name, and can be manipulated
              independenty in the geometry viewer, if lock mode is not
              selected. The color range is defined externally in the
              colormap data structure.

Module path : avs.ncsc.org:avs_modules/mappers/irreg2map
Ported to   : IBM Convex Kubota Sun HP
Description : IRREG2MAP is intended for applications in which data from
              scattered sensors is stored in irregular fields, and needs
              to be displayed, or processed , as uniform data. In
              particular, a time series of measurements may be stored in a
              2D irregular field, with the one compute dimension
              representing time, and the other dimension the data values
              recorded at that time. For the data to be displayed in the
              Image Viewer, or as a texture map in the Geometry Viewer,
              this module is needed to create the uniform field required.
              IRREG2MAP produces a uniform byte field in which the pixels
              are set to zero, except where data from a selected row or
              column of the input field exists. The resolution of the
              output field is determined by the X_start, Y_start,
              X_stop, Y_stop, X_step and Y_step parameters. The module
              ignores any Z data in a 3-space field. The X and Y limits
              determine the range of coordinates, present in the input
              field, that are mapped into the output field. Values which
              fall outside the range of coordinates selected for the
              output field are ignored.

Description : This module draws vector arrows on the lattice of a 2D field,
              at the node positions. It draws arrows in the 2D plane, given
              X-Y vector components. The downsize dial subsamples the
              mesh, so not all nodes get arrows, for clarity. There is
              never a Z component to the vectors, except that the arrow
              heads are 3D pyramids. Even if the input field is 3-vector or
              more, it only draws arrows assuming 2D vectors in first two
              vector components. The arrows are constructed from
              disjoint line segments.

              copies, and produce one geometric object out of many,

              "geom_duplicate.c" from Ian Curington (AVS Inc) as a basis
              to generate this module. Take up to 6 geom input ports,
              combine into 1 geometry then duplicate and mirror
              according to flags (can mirror in x and/or y and/or z and all
              3). Also allows the user to set transparency level for all
              objects being mirrored, can also - select wireframe mode,
              cause AVS to compute the normals, and hide probes (anything
              with "probe" in the name). Lighting, rendermode,
              perspective, are controlled by toggles. This was used in to
              represent a section of a magnetic field, showing the whole
              from the input of just one quadrant.

              experimental data. FIELD PARAMS returns the X and Y
              dimensions of a field as integer parameters, and the
              minimum and maximum values of the field as float
              parameters. It allows each of these parameters to be scaled
              by its own scale factor. FIELD PARAMS is used to provide the
              GENERATE COLORMAP module with the range of the data values
              (cf COLOR RANGE), while also allowing the user to modify the
              colour range. It also provides the X dimension ofthe field
              as an upper limit to the ANIMATE INT module which controls
              the position of the viewable window.

Ported to   : IBM Convex Kubota Sun HP
Description : DRAW TRACKS is a module provided to demonstrate the use of
              the geometry viewer to display two-dimensional track
              information provided as a floating point 2-vector (x,y)
              input field. If the input field has more than one dimension,
              multiple tracks are displayed. If the field is 3-vector, it
              uses the third vector component to color the lines, with the
              optional colormap input field. The hi-low dials of the
              colormap control the line color range. DRAW TRACKS also
              allows the user to select a track of interest by clicking the
              mouse on it. The selected track is highlighted by changing
              its colour, and the selected vertex is indicated by
              positioning a sphere over the vertex, and a line connecting
              the vertex to the sphere. The coordinates of the selected
              vertex are displayed in a text window.

I know this is graphics.avs, but I was wondering if anyone knows who teaches
AVS classes?  I kow that Clarity Learning teaches some, but I do not know the
relationship between Clarity and AVS.  For example, I recently attended the MPGS
5.0 class from Cray.  The MPGS development team taught the course, so any
questions you asked were answered by the experts.

If anyone knows how I can get in touch with AVS or knows of other places
offering AVS classes, I'd really appreciate it.

Thanks.

Matt.

Ported to   : IBM Convex Sun HP
Description : This module produces an arbitrary line of sampled node data
              from a 3D UCD mesh and outputs it as a field. This can be a
              conventional AVS 1D field with irregular 1D coordinates or
              a 2D field suitable for connection to the graph viewer
              module. It is also possible to output a uniformly spaced 1D
              field. Version 2 fixes bug concerning disappearing input
              ports. Ported to IBM 12/18/92 SRT. Version 3 changes - Code
              is ANSI C, therefore it requires AVS 5. Modules have been
              restructured to make them cooperative and reentrant. They
              are now designed to be compiled in a single executable. If
              you want to split them up on the FTP site refer to the README

Ported to   : IBM Convex Sun HP
Description : This module draws geometric representation of UCD input
              showing CELL data, CELL Material ID, or Cell Number
              Sequence. This is a special ucd mapper module designed to
              make representations based on CELL based values rather
              than the more typical NODE based values. If you have CELL
              based values, you should consider the ucd_cell_to_node
              module. This module colours each cell ONE color, without
              color interpolation, showing a single scalar quantity. If
              your cell data is n-vector, this module will only color the
              first one, so use ucd_extract to get the one you want. It will
              color the cells based on [1] the linear cell number, or
              cell_id tag. It maps this range onto the color input map. [2]
              cell scalar data. Use the "upper" and "lower" colormap
              dials to set the color to value mapping. [3] material id
              numbers. It maps the max material id to cover the input color
              map range. This module also has a direct SHADED/WIRE_FRAME
              toggle control, just to save time going to the viewer panel.
              This module is not like the standard ucd_to_geom, in that it
              - does not cache information about the ucd structure in
              between invocations, - does not have a color array input
              from ucd_legend, rather it colors directly with a colormap
              input, - does not have "external faces" mode - does not have
              "explode materials" mode - does not have "shrink" function
              - containes no calls to internal unsupported utilities -
              does not cache geometry for fast animation - does not
              process node data at all. This module is intended as a source
              example for other UCD module developers.

              pipe.file p) to another application program, where
              command input has been redirected to the same pipe. This

              containing a description of the atomic co-ordinates of the
              structure or molecule to be visualized and output AVS
              geometry representing a ball-and-stick or space-filling
              model of it. The read shak module is suited to interactive
              viewing whereas the shak_to_geom filter is useful for off-
              line creation of a sequence of .geom files for animation by

              the cfd data as a ucd data set. The dummy nodes stored at the
              edges of each computational block are removed by the
              module. The n-vector data at each computational cell is
              stored as cell data, to use most of the ucd modules, this must
              be converted to nodal data. The cells of the ucd structure
              are all hexahedra. See the sample data directory on the
              International AVS Center's anonymous ftp site for two

Description : This module navigates a menu structure which can be
              designed and configured by the user. Each menu level is
              described by a single ASCII text file. A menu level contains
              several buttons with user-configurable names. Each
              button results in one of three basic kinds of action in the
              module - load a new menu level, pass a command to downstream
              modules, or go to a file to find a series of commands to be
              passed to down stream modules. Option 3 allows multiple
              commands to be played in background as the result of a single
              button press. The file containing the commands to be played
              in background is the second type of file associated with
              this system. Thus there are two types of file - the MENU FILE
              to define a menu level, and the AUTOMATIC FILE which
              contains a series of commands to be executed.

Submitted   : 09/30/93        Last Updated : 09/30/93  Language   : C
Module path : avs.ncsc.org:avs_modules/filters/ucd_select
Ported to   : HP
Description : The ucd select adjusts the minimum and maximum values of a
              colormap to those of a selected scalar component of UCD
              nodal data. The module is functionally similar to the color
              range module which performs the same operation for fields.
              However, as ucd contour already normalises the colormap
              this module is not required to correctly color ucd
              structures. Instead, it is intended that this module be
              used to provide a alternative mechanism for using the color
              legend and label modules with UCD data to that offered by the
              ucd minmax module. In this respect the ucd color range
              module offers a superset of the functionality of the ucd
              minmax module - filtering the ucd input. The ucd minmax
              module relies on network connections to the generate
              colormap module in order to set the bounds of the colormap.
              In contrast ucd select filters the colormap output. This
              colormap can then be passed to the color legend module.
              There are two principal advantages to using this module
              over ucd minmax. Firstly, the module offers more control
              over what type of changes in the ucd input cause the min/max
              values to be reset. The other major advantage is that the
              chosen component is made available on an output port. This
              can then be used to control the 'Node Data' parameters of
              other ucd modules. This makes it possible to select a
              component throughout a network at a single stroke. This
              makes it much easier to design ucd networks with a clean user
              interface. The other output of the module is a title string
              which can be used with the label module.

Description : The ucd comp module allows a component of model, cell or node
              data to be selected from a UCD structure. The selected
              component is made available on an output port. This output
              can be used to set the component parameters of other ucd
              modules via network connections. This allows a single set
              of radio buttons to control component selection in a number
              of UCD modules within a network. A component of model, cell
              or nodal data is to be selected. This is controlled through a
              choice widget. It is likely that in a network this parameter
              will be not be modified. Therefore, it is envisioned that
              the network editor will be used to delete this set of radio
              buttons in most networks. The module also outputs a
              suitable title string for the selected component.

              is the 3D analog to a Sierpinski Carpet which is can be poorly
              defined as a recursive 3x3 grid where the center square of
              each level of the recursion is missing. A more formal
              definition can be found in Benoit Mandelbrot's book "The
              Fractal Geometry of Nature" on page 144. You can see a
              Sierpinski Carpet if you orthoslice the sponge and look at
              slice 0 (any direction). CURDLE (at the IAC) is another

Module path : avs.ncsc.org:avs_modules/filters/slave_slicer
Ported to   : Kubota
Description : The slave slicer module extracts a 2D slice of a 3D scalar
              field. The slice to be extracted is specified by the
              slice_spec structure input. The slice_spec structure
              will usually be produced by a separate module that contains
              control widgets for specifying the slice in a way suitable
              for the given application. The "specify slice" module, for
              instance, creates a slice_spec scaled to the input data
              extents, and specified by Euler angles. Other modules
              could be written if another method of specification is
              desired. A module has been written, for instance, to take
              slices perpendicular to a beam of radiation used to treat
              cancer. The output is a 2D uniform field, with coordinates
              specified in the 2D coordinate system. The minimum and
              maximum X and Y coordinates correspond to the extents given
              in the slice_spec. This data type is the most
              space-efficient representation for image data. If the
              coordinates of the data in the original 3D system are
              desired, the "reconstruct slice" module will reverse the
              transformation and produce a 2D 3-space irregular scalar
              field, suitable for visualization with "field to mesh."
              The geometry output is a simple rectangular polygon
              corresponding to the size and position of the 2D slice in 3D
              space. It is useful for quickly depicting the slice in
              relation to other objects in 3D. The three modules in this
              package, "slave slicer," "specify slice," and
              "reconstruct slice," are a flexible and efficient
              alternative to "arbitrary slicer" and Wes Bethel's "new
              arbitrary slicer." Slice specifications are generated by
              a module separate from the actual slicing module. That
              permits a single specifying module to specify identical
              slices through multiple data sets, and also for users to
              create their own modules to specify slices. The slicing
              algorithm takes 2D slices of 3D scalar fields (uniform or
              rectilinear) and outputs them in the most space efficient
              format, 2D uniform. 2D 3-space irregular output, similar
              to that output by "new arbitrary slicer" can be generated,
              if needed, using "reconstruct slice."

Description : The specify slice module creates a slice_spec structure,
              suitable for use with the "slave slicer" module to extract
              2D fields from 3D scalar fields. The 3D field can be of any
              data type - the field is used only to scale the extents so that
              the 2D slice will cover the extents of the field. The slice
              orientation and resolution are controlled by the
              parameters. The X and Y resolutions are identical, and the
              scaling of the slice is selected to cover the "shadow" of the
              3D field in this orientation and maintain the "aspect
              ratio" of the input. That is, parallel slices made by
              varying the "Z Translate" parameter will all be the same
              size, and the geometrical proportions of the input are
              preserved. The three modules in this package, "slave
              slicer," "specify slice," and "reconstruct slice," are a
              flexible and efficient alternative to "arbitrary slicer"
              and Wes Bethel's "new arbitrary slicer." Slice
              specifications are generated by a module separate from the
              actual slicing module. That permits a single specifying
              module to specify identical slices through multiple data
              sets, and also for users to create their own modules to
              specify slices. The slicing algorithm takes 2D slices of 3D
              scalar fields (uniform or rectilinear) and outputs them in
              the most space efficient format, 2D uniform. 2D 3-space
              irregular output, similar to that output by "new arbitrary
              slicer" can be generated, if needed, using "reconstruct
              slice." The slicing algorithm is generally faster than
              "new arbitrary slicer," at least on the Kubota
              architecture. RELATED MODULES - slave slicer,
              reconstruct slice

Ported to   : IBM Convex Kubota Sun HP
Description : The module passes through any geometric input appending to
              its name a string uniquely describing each instance. When
              no additional input is supplied, the string is just the
              current number (increased by one at each call, when
              Increment button is on, reset to 0 when Reset button is
              pressed or alternatively set to the value typed in).
              Otherwise, the value at input is converted to string and
              appended to the name of the input object. This allows e.g. to
              obtain a series of isosurfaces named "isosurface_75.0",
              "isosurface_75.5", "isosurface_76.0" etc.

Description : The field to map module converts 2D scalar field into a
              surface in 3D space, represented as a GEOM-format mesh. The
              geometry is annotated with boundaries, tick marks and a
              colour scale, for geographic map visualisation. The input
              data must be a 2D field with a scalar data value at each
              element. The extents of the field are used to annotate the
              map.

Description : Field Concat concatenates Out Veclen instances of input
              scalar field into one vector field of dimensions and type
              same as the first scalar field (if a field of another
              dimensions and/or type occurs at the input, the module
              starts creation of a new vector field as in the case of
              changing of Out Veclen or resetting). If increment is on,
              neach new input increments the index parameter filling
              sunsequent components of the field. The user can control
              the index parameter manually usinf set button to fill in new
              components. If all components of the outfield are set, the
              module spits it downstream.

Description : STEREOGRAM produces a version of a "random dot stereogram"
              based on an image which represents distance to the eye. An
              easy way to get this kind of image is to use the Z-buffer
              output from the AVS geometry viewer's software renderer. A
              random dot stereogram is an image where if you diverge your
              eyes while looking at it, the left and right eyes will see a
              different image and a three-dimensional surface will
              appear. Two squares are drawn in the top of the display. One
              method of viewing the stereogram would have you stare
              "past" the image so that the squares appear to overlap. Hold
              that for a few seconds and (for some people!) a shape will
              appear to either protrude from or recede into the image
              plane.

Description : The cone module transforms an AVS geometry, replacing a set

              The cones are colored based on the colors of the input
              geomtry. Everytime the input geometry changes, cone tries
              to find a suitable radius by calculating the average length
              of a line segment. The min and max values of radius are set to
              1/10*r and 10*r (where r is the calculated radius).
