I'm using AVS to display WSR-88D radar data in 2-D and 3-D.  Not a fun chore
since AVS only allows cartesian coordinates.  

Any of you AVS guys know of any plans to include the ability to specify data
in spherical or polar coordinates in AVS 6?  It would make lots of
meteorologists really happy....

This module will hopefully do the trick.

Name        : irreg_2_reg     Version      : 1.000     Mod Number : 1047
Author      : Wes Bethel, Lawrence Berkeley Laboratory
Submitted   : 10/10/91        Last Updated : 10/10/91  Language   : C
Module path : avs.ncsc.org:avs_modules/filters/irreg_2_reg
Ported to   : Sun HP DEC IBM Kubota
Description : Converts an irregular field to one which is uniform by
              removing the coordinate information from the irregular
              field. Converting an irregular field to one which is
              uniform is useful when one wants to create a "scalar mesh"
              (using field2mesh) where the elevation is derived from an
              associated scalar value in the field. Field 2 mesh creates a
              "scalar mesh" only when the input field is uniform (not when
              rectilinear or irregular).

Enjoy,

-Steve

Well, I obtained and compiled the module, and it seems to work.  I've
developed a problem with the entire system though, which is shown above.
WRITE seems to write every image _twice_ while the animation is running,
which not only slows it down (presumably) but creates a real problem in
that a lot of the secondary files are smaller and missing parts of
themselves.  I've checked carefully from the Unix prompt -- all the
files are fine the first time around, but the second ones are easily
screwed.  So it'll write anim2.001 (42 Kbytes), then again (27 Kbytes)
then go on to anim2.002.  Help?

Hi Folks,

The International AVS Center is implementing an
official Preventative Maintenance (PM) time on the
machine avs.ncsc.org.  Beginning this week, this
PM time will be every Thursday, from 6-8 AM E.S.T.

During PM times, it is possible that avs.ncsc.org
will go offline for hardware and/or software
maintenance purposes.  Most of the time the machine
will probably provide uninterrupted service, but
in the event service is scheduled we will do our
best to limit it to these hours.

Thank you for your understanding.

The answer is that Write any image fires any time any input or param is
updated, this can mean twice per cycle. How to fix this......

Well, there's a couple of neat code fragments in the write_compressed
modules, and I borrowed some of them to write a module that fixes this 
as well as a whole list of shortcomings of the READ/WRITE ANY IMAGE 
modules, but it is not yet available from the IAC. Undoubtedly this is 
because it requires quite a bit of ancillary stuff (like WRITE ANY IMAGE
does), and Steve et al. haven't gotten a chance to slog through it all.
If the thing passes muster, I'm sure they will release it soon. (hint hint)
 

Anyway, if you feel like doing a bit of C hacking, you can set it up
such that the module only fires whenever AVSparameter_changed returns 1
for lets say the filename string being changed. (Otherwise have the module
return 0), or something like that. 
Not too much code to be inserted. 
Good luck,
A.J.

steve thorpe made reference to a module which will throw away all the
coordinate information, thus making a "uniform" field.  this is a hack,
to be sure, but often useful.

i suspect that there is a deeper problem here, though i could be wrong
in my interpretation.  "isosurface" indeed can process a 3d field with
irregular coordinates.  the fact that you're posting this question leads
me to believe that you have a field with 3d coordinate information, 
and a computational space which is NOT 3 dimensional.  in which case
you're hosed, sort of.

if the data is 1 dimensional, but with 3D coordinates (a scatter field),
you can compute a 3d, 3-space field using one of trivar or scat3d (from
the IAC), or you can try converting the scatter field to a UCD (which
uses delauney triangluation) and then use some UCD tools on that.

  _ 'choose_file' CLI command
  _ 'net_flow' CLI command
  _ 'net_group' CLI command  (i.e. Module Tags)
  _ 'net_map' CLI command  (i.e. Module Maps)



Rank these Geometry Viewer features using the following scheme:
(1 = use frequently, 2 = use sometimes, 3 = never use)

  _ transform camera
  _ transform light
  _ object transform mode
  _ sphere sub-division level
  _ metal property
  _ axes for scene

Anyway my question:

I want to produce videos from an animation.  Yes I read the "animating

1. what videos equipments (type of vcr, cables) I need
2. more detailed instructions to accomplish this

I have a Sparc 10/51 running SunOS 4.1.x.  Many thanks.

Dear AVSers,

Has someone implemented a sort of 3-way orthogonal slicer?
That is, it simultaneously displays 3 cross sections: (X, *, *),
(*, Y, *), and (*, *, Z).  The user can then click on any one
of the cross sections, e.g. (X, *, *), to locate a point, say
(X, Y', Z'). Then, the other 2 cross sections automatically
become (*, Y', *) and (*, *, Z').
Thanks.

	       1994 Symposium on Volume Visualization

		 October 17-18, 1994 Washington, DC
				   
	        ====>>>>  CALL FOR VIDEO  <<<====

The Volume Visualization Symposium, sponsored by ACM-SIGGRAPH and the IEEE
Computer Society Technical Committee on Computer Graphics, seeks 
entries to its Video Session and tape.  In the Video Session authors will
present recent results shown in the video. Presented contributions will be
collected in a tape and distributed to all the participants of the symposium.

Submissions to the video session and tape should include a VHS tape
(NTSC or PAL) accompanied by a short abstract with explanatory text or
narration. Please submit, on or before September 20, 1994 to:

	Holly Rushmeier
	Rm. B-146, Bldg. 225
	NIST
	Gaithersburg, MD 20899
	Telephone: 301-975-3918
	Fax:       301-963-9137
	Email:     holly@cam.nist.gov

Please label both the videotape and its container with the contact 
person's name, affiliation, address, telephone number, title of piece,
and runtime.

Although we prefer reviewing the video clip itself, due to the short notice
we will also consider abstracts accompanied by snapshots taken from the 
video clip to be presented. Accepted contribution of the latter type will
be presented in the symposium but not included in the distributed tape.

Suggested topics include, but are not limited to:

* Volume visualization of unstructured and irregular grids.
* Discipline-specific application of volume visualization.
* Parallel and distributed volume visualization.
* Hardware and software systems.
* Analysis and control of rendering quality. 
* Volume segmentation and analysis. 
* Rendering of large datasets.
* User interfacing for volume visualization systems.
* Acceleration algorithms for volume rendering.
* Fusion and visualization of multimodal and multidimensional datasets.
* Visualization of non-scalar volumetric information.
* Modeling and realistic rendering with volumes.

Note that VMS is NOT an OLD operating system (Unix is older).
Also note that VMS is definitely supported by DEC on VAX and Alpha's both.
Then again, I may be the only AVS for VMS licensee.  So 5.01 is the last
I'll see.

I do thank AVS for actually shipping a usable AVS 5 for VMS before junking
it.  Works quite well, thank you.

Exactly.  Let me quote from DEC's two-page ad which appeared three weeks
ago in the major newspapers (New York Times, Wall Street Journal, etc.)
     We offer OpenVMS(TM) because millions need it, as it provides
     the best clustering capabilities on the market for high-security,
     high-throughput, business-critical work. We plan to support it,
     invest in it, keep customers fully operational with it, and
     introduce it to new customers as well.

I would definitely like to see AVS supporting and investing in VMS too.

>Then again, I may be the only AVS for VMS licensee.
Well, here is another one.

I'm a bit confused. Is AVS removing support for VMS or not. WE were about
to buy AVS as the base of a large instrument,data analysis programme. We would
have a fairly large user base who would also buy the packages, but we and our
users are VMS based. I noted before I saw this thread that the VMS version of
AVS was considerably (1000 pounds) more expensive than the UNIX version. THat
should have warned me. Would anyone care to suggest a similar tool which will
maintain support for VMS. I already know about IDL.

Hi all,

I am trying to locate a gradient module that will work with a variety
of data set types.  The problem I'm having with the Compute Gradient
module in the standard libraries is that it appears to normalize the
data before it gives an output.  I need something that will only
compute the gradient.  I unfortunately do not have Khoros running so
I cannot use any of those modules.

Thanks,
Rob

Maybe this module could be used as is or modified to do the job?

Name        : vec_mag_2d_v    Version      : 1.000     Mod Number : 1090
Author      : Wes Bethel, Lawrence Berkeley Laboratory
Submitted   : 10/10/91        Last Updated : 10/10/91  Language   : C
Module path : avs.ncsc.org:avs_modules/filters/vec_mag_2d_v
Ported to   : Sun HP DEC IBM Kubota
Description : Computes a two dimensional gradient from a two dimensional
              scalar, floating point field (image). This operation is
              useful in many image processing applications. There are no
              parameters with this module. The documentation
              accompanying the module shows a network that reads in an
              image (a good test case is the "stardent.x" image), then
              extracts one of the rgba fields from the image, then
              computes a 2d gradient from the resulting gray image. Next,
              they extract either the x- or y-component from the gradient
              field and display the result as a grayscale image.
              Switching from channel 0 to channel 1 in extract scalar
              shows the y-component of the gradient.

Good luck with it.

Information on the WASHINGTON D.C. area:
****************************************

With the nation's capital at its heart, metropolitan Washington spreads into
Maryland and Northern Virginia.  More than 3 million people make this the
eighth largest metropolitan area in the country.  The conference itself will be
held in Tysons Corner, in Vienna, Virginia, just 20 minutes from downtown
Washington, DC.

Tysons Corner's strategic location between Dulles International Airport and the
Washington Beltway has not only made it one of the Washington areas fastest
growing employment areas, but also a popular entertainment center, with
restaurants, movie theaters, and some of the finest shopping in the Washington
metropolitan area.  Enjoy cultural events, concerts, opera, musicals and
theater at Wolf Trap, America's national park for the performing arts, only one
mile from the hotel.

Washington, DC, attracts millions of visitors each year to its monuments and
museums.  The Smithsonian Institution alone draws more visitors than any other
tourist attraction in the country, including Disneyland.  In this city of
tree-lined avenues laid out nearly 200 years ago by French surveyor Pierre
L'Enfant, there is much to see and do, from sightseeing, to picknicking on the
Mall, to attending cultural activities.

In response to my post about Stardent Computers in comp.sys.mips, I got
a nice reply from an individual in the Engineering Department at Kubota
Computers, Inc.

He suggested that I contact someone in sales at "Kubota Graphics
Corporation",  formerly Kubota Pacific Computer, Inc., which took over
the TITAN  hardware from Stardent.  He also said that the operating
system which our Stardent 3000 runs, currently Unix Release 3.0.3, was
revised to version 4.2, but that the final release (version 4.2) was in
1992. Which tells you how long we haven't really paid attention to this puppy.

So I guess I'm looking for contact(s) about Titan Hardware which was 
supportted by Kubota Graphics in 1992.

If anyone out there has tapes or sources for this equipment they want 
to dump or sell for cheap, please let me know.  We're looking to make 
this a simple enduser machine, especially since it is no longer 
actively supportted.  Of course, I'm not asking anyone to violate a 
licensing agreement on the operating system software.

If you can help or point out a site, I'd appreciate the help.

we are running avs on a data general aviion and having all kinds of minor

I am running AVS on a Kubota workstation, and having a bit of a problem. I want
to make multiple images of different views of objects in the geometry viewer.
I have the views I want images of saved as a .scr file, via save scene in the
cameras menu. I want to use the module write image to get my images. When I go
into the network editor, I connect the geometry viewer to write image, and I get
the usual display window for the geometry viewer. But when I tell the viewer to
load one of my .scr's, it pops up a new window, titled merely 'AVS', that 
contains the scene I want. The write image module takes its image from the
original geometry viewer window, which remains blank. I cannot get it to write
the image I want in the new window, even when there is a red border in it to
indicate it is active. Is there some way around this problem?

Summary: Quickie questions, large data file concerns.

Hi, All.

I have been reading about AVS (and IDL), as I prepare to choose
between them for an image processing application involving 
electrophoretic gels from a DNA sequencer.  May I ask a few questions?

1) LARGE data files.

Our data files run between 12 and 20 Mgb in size, and they are 16-
bit values.  I located an AVS module on the ftp server which seems
perfect for helping me get the images into AVS:  

DESCRIPTION  (excerpt from module description)
  READ 16 BIT IMAGE reads a 16 bit integer binary image (2D collection
  of bytes) off of disk and into an AVS integer (32 bit) field. It does
  this by reading the 16 bit intsinto a 'short' buffer and then casting
  them into 32-bit integers. If you don't know what the resolution of

QUESTION: Must I load them as 32-bits?  Can't they remain 16 bit values?
          I *know* I don't want to go down to 8 bits, but the doubling
          in size of the 16->32 conversion will make my already huge data
          file even huger! I have 64Mg of RAM, but...I am skeptical.

          What are the practical limits on image file size?

2) PV-WAVE

I read a lot about it in the like-named newsgroup.  If I *don't* have it,
will I still be able to do symbolic math, array operations, curve-fitting,
etc?  

3) ALA CARTE AVS

If I find that certain of the main capabilities of AVS, e.g. 3-D support,
are never used, can I remove them from my installation and thus save
space and/or memory during execution?

4) LEARNING CURVE

Can an experienced C programmer / Unix person get going and, say,
load an image into AVS and perform a few manipulations within a day or
two of installing AVS? (generally)   Do you agree that IDL has a gentler
learning curve, but is less rigorous and lends itself to sloppy programming?

5) VERSIONS

What is the difference between AVS Express and AVS? 

6) SUPPORT

Do you get good support?  I can't seem to get anyone at their 617-890-4300
number.  I left a message and have not heard back.  They have a "local dist-
ributor", who is a nice guy, but it makes me wonder if they lack a corporate
identity.

Thanks for any responses on these questions, or any insights/advice you may
offer.  And if there is an archive site I should know about, 
sorry... I try to be good about reading FAQs and such before posting.

Sincerely,

I am creating some animations of various senarios of a simulation,
for which I have created networks, but I would like to pan smoothly
around my visualization along the *same* path for each senario.  I've
had two difficulties:

	i) setting up the smooth path initially.  Setting the camera
	   positions manually and recording key frames in Animator tends
	   to produce wobbly rotations, while setting the from/to/up
	   vectors manually can be tedious, particulary since "up" must
	   be maintained perpendicular to the from-to vector.

	ii) I would like to be able to save the camera path and load it
	   into another network.

I've looked briefly at the flight_path and place_camera modules from the
Submitted modules, but they haven't been too much help.  Both still
requires the accurate computation of "up" normal to from/to (as far as
I understand it), and flight_path requires the creation of a scatter field
of camera positions (is there a tool for creating this conveniently?).

Are there existing solutions to this problem that I don't know about or
can someone suggest a simple/convenient way to approach it?

Thanks!

Hi.

This may be a real stupid question. Is there an analog to optimal 
control using stochastic differential equations in discrete time? In 
continuous time one works regulated Brownian motions. What would be such 
a thing in discrete time, and what would be a good reference?
(Please reply by email)

Hello,

I just started using AVS and I had some questions that I hope can be answered.  
First, if there is a FAQ out there somewhere which answers my questions, I humbly 
apologize.  I'm trying some simple graphing using the Graph Viewer's read_field module
but I'm a bit confused among ndim, nspace, and veclen.  The manuals did not clear up my
confusion so I hope someone out there can answer this in simple terms.  Also, what is 
the difference between 'coord' and 'variable' in the field files?  If anyone is kind
enough to respond, please do so by e-mail (pnohalty@fourier.oac.uci.edu)  Thanks!

Anton,
	I have encountered the same problem you described and I worked around
it like this:
	
	First, use your favorite editor and change the .scr file itself.  The
first line will look something like:

geom_create_scene -scene "geometry viewer.user.0" \
                -view "Camera 1" 17 212 600 600

Comment this out with a # and add the following lines to replace it:

present "Network Editor"
module "geometry viewer"
geom_set_view
geom_set_camera_name "Camera 1"   # Note - make this name match the one in the
				  #        commented line above

Now the modified .scr file is run from the AVS CLI.  Start up AVS
with the -cli option, and then simply source your file:

avs> source filename.scr

The scene appears in your geom-viewer window and you can tack on the write
image module in the regular way.

Incidentally, if there IS a quicker way I'd like to hear it too! :)

Hope this helps.

Here is one data point.  It took me a day to skim over the manuals. 
Several hours to go over most demos and find out what the modules do.
Playing with the geom and image viewer takes a few hours.  Network 
programming takes a few days to be comfortable with.  The most time
consuming part is learning to write modules.  It took me a few weeks to
be able to write some useful modules for my applications.  I'd like
to hear how other newcomers break in.

Support?  What support?  My sales rep is helpful and responsive.  But once
the ball goes to the support group, forget it.  I had a minor
problem in installing avs.  A request for help was sent.  Never
heard from it again.  Meanwhile I manage to solve the problem on
my own.  First impression does matter ....

 my experience was just the opposite. I used the avs support email address
 and got lots of good response on all kinds of topics. 
 General stupid learner questions, 
 through programing a couple dozen modules, 
over a 6 month or so period.

Yep, there is, and it makes the previously horrendous (impossible?)
task of smooth camera motion easy as clicking a few buttons.  It's
called the Spline Animator, and it was created by Mitch Roth and
Mark Astley.  If you were at AVS 94, you saw an awesome fly-by of
Mt. Redoubt eruption using the Spline Animator.  We've used it here
at the USGS for serveral fly-bys, and it works great.  Contact
Mitch at roth@acad5.alaska.edu for info on the module.

I heavily use the support from AVS, and I have always gotten 
very good assistance.  I almost always communicate through 
e-mail, however, so I don't know what their phone supporet is like.

The "short int" data type is what you want.  Since the source code is
available, you may be able to modify this module to output short ints. 
Also, consider ADIA as a way of importing data.  (I'm starting to look into
it just now for something I need to do, so I can't yet comment on how well
this works!)

Probably not too much.  Many of the modules execute from a BIG executable
called mongo rather than as separate pieces.  You can always delete the
data files that the demos use, but I find them rather useful.

Ask your sales person to send you info on Express.  It is quite different
in many ways, but somewhat similar in others.

It's a little sporadic.  Sometimes I get an answer in a few hours
(support@avs.com), most often in a day or two, and occasionally things seem
to get lost.

Good luck,

I have had very good luck and relationships with the support 
personnel at AVS.  I've needed chunks of code and some debugging
help and have always gotten what I needed in a very timely
manner.  I guess I could always wish for faster turnaround, but
I generally have what I need in a day or so.  I almost always
use e-mail for my communications, since it seems to be a bit
faster than the phone, but my phone response has been good, too.

Don't know if this helps.....

I've been experimenting with writing some of my own geometry creation
subroutines and have a question.  Is there any way to assign a color to
an individual polytriangle/mesh component/etc. rather than to the vertices?
This seems like an obvious thing that people would want to do; however, the AVS
manual says that you can assign data to each primitive but the geometry
viewer doesn't use it.

Why?  Or am I missing something obvious?

I need to write a module that acts like a very simple image viewer -
it takes a 4-vector byte input and opens an X window displaying that
image. It also needs an output port that acts something like image
viewer's mouse info port, to send mouse events upstream.

Before I reinvent the wheel, does anyone have source for something
similar? Any sort of module that opens and displays in an X window
would be useful.

I don't think I can use the existing image viewer, because I need to
get events from all of the mouse buttons (image viewer will only let
me get at the left button).

Hi Mike,

I would recommend checking into these modules, maybe you can
use them or modify them to suit your purposes, or at least get
some ideas from them.

Good luck with it!

Author      : Ian Curington, Advanced Visual Systems
Submitted   : 08/31/92        Last Updated : 08/31/92  Language   : C
Module path : avs.ncsc.org:avs_modules/data_output/display_tracker
Description : Track 2D cursor motion over displayed image. This module
              takes an input image and displays it in an X-window. Inputs
              an image and allows the user create mouse clicks and moves in
              the image window, with event information passed to other
              AVS modules using the "upstream data" concept. This module
              acts similarly to "display image" or "display tracker" in
              that it accepts an input image and displays this in an
              X-window. It also then accepts asynchronous mouse events
              in the window, and passes these mouse events ( in an upstream
              transform structure ) to an output port. This allows
              applications to be built using this module to do all the X
              dependent code, leaving the actual operation (such as pan,
              draw, etc.) to an upstream module, with no concern of X
              events.

Submitted   : 10/10/91        Last Updated : 10/10/91  Language   : C
Module path : avs.ncsc.org:avs_modules/filters/draw_pixel
Description : Draws pixels into an image. Uses upstream transform
              information to draw pixels over an input image (paint). It
              is designed to take an input image, and copy it to the output
              port. This is a straight pass-through. If, however, once
              and image is passed, it can scribble on top of the image with a
              square-block brush in light grey. The mouse (brush)
              position is fed externally from this module, getting the
              current mouse position and button state from the "struct
              upstream transform" input port. This is designed to be used
              with "track_cursor", which displays the image and catches
              the X events.

Module path : avs.ncsc.org:avs_modules/filters/panel_pan
Description : Uses upstream transform information to crop an input image
              and display one panel at a time. It is designed to take an
              input image, and copy it to the output port. This is a
              straight pass-through. The size of the output image is
              1/panel_res of the input image. The module sensed mouse
              activity in borders near the edge of the window, and will
              flip to the next panel in that direction. The mouse position
              is fed externally from this module, getting the current
              mouse position and button state from the "struct upstream
              transform" input port. This module is designed to be used
              with "track_cursor", which displays the image and catches

I have an ascii-file with x, y, z points, which I want to display as surface.

The points are aranged in this way:
71500.04   275500.03   1011.06
71500.23   275520.03   1017.86

71500.80   275580.44   1016.70
...

I can read these points as "field 1D 0-vector irregular float" and
display them in a 'geometry view' using the module 'scatter dots'.

Is there any possibility to triangulate these points into a "field 2D",
so that I can display them as shaded surface? 

Thanks for any help or hints,

Hallo,

perhaps this is a real stupid question and the answer will be 'read page xxx 
of the manual', but it is an important one for me.

We are using the NAG Fortran-90 Compiler for programming in signal processing 
(medical ultrasound). Up to now we are using the AVS for visualisation with 
standard routines and routines we write in C. 
Now we want to write AVS-modules in Fortran. Unfortunately this shows to be
quite difficult: The AVS-part of the source file is generated correctly (though in 
FORTRAN 77, but ok). So I fill in my part, compile, (everything is ok up to now)
and link, and then it happens: Lots of unresolved externals populate my shell 
window, things like 

     __ansi_fflush
     __f77_init
     __f77_end 
etc..

I tried to compile with a FORTRAN 77 compiler, but with the same result. 
So does anybody has experience with programming AVS in Fortran-90 or
FORTRAN 77? Can you tell me how to link my file correctly?
Many thanks,
      Kai Eck

Try the final linking step with the fortran compiler instead of the
C compiler to automatically pick up missing FORTRAN libraries.
For example:

f90 *.o $(AVSLIBS) -o a.out

I have not looked on the IAC ftp site to see if there is such a module,
but if there is not, then I would suggest using a group of image processing
utilities called imtools.  They are available from the San Diego 
Supercomputer Center (SDSC) via ftp at ftp.sdsc.edu, in the 
/pub/sdsc/graphics/imtools directory.  One of the programs in this package 
is called imconv, for 'image converter', and will convert from the Sun rasterfile 
format into an AVS x format.  

There is an AVS module called Read Any Image at the IAC ftp site, but what it
does is call the SDSC imconv program, so you will still have to get imtools first.

Hope this helps,

I'm creating an AVS-module for a comparison of several methods of handling some data.
In order not to confuse the user with too many parameters I am trying to create and
remove widgets from inside the module so as to show only those parameters that are
relevant for the method that is selected in a choice-parameter. So far I have tried
two things :
a) creating all parameters and widgets in the ModuleGenerator and using 
   AVSparameter_visible to put widgets on and off display from inside the
   module compute routine.
b) creating only the choice parameter for the methods in the ModuleGenerator
   and using AVSadd_parameter and AVSconnect_widget from inside the compute
   routine to create new parameters in accordance with the choice of method
   by the user.
Despite the fact that AVS runs through the whole module - or at least the
compute routine - whenever any parameter to that module is changed, neither of
the two methods described above seems to work.

Is there any other way of creating or hiding widgets on the fly ? 
I'm grateful for any hints...

Thanks, Axel

Subject: Lingering particle tails in Particle Advector
Date: 22 Sep 1994 16:17:26 -0600

I'm using the Particle Advector coroutine to move streak lines through a
vector field, much like the particle advector demo, except that I'm using the
"cycle" tracer style. This main difference is that the tracer is always n
previous values, so it stays attached to its particle, and is a moving line
segment rather than reaching its length and stopping.

I find it annoying that when a particle leaves the space that the vector 
data occupies, its tracer doesn't keep moving out of the volume, but it 
sits on the edge, cluttering the view. Does anyone else feel the same?

Has anyone done a workaround to this? Being a source licensee, I can probably
make a fix myself, but unless it gets incorporated into the real AVS
distribution, it'd be bad form for me to implement it and have the Cray-3
version produce different pictures than any other version.

Thanks,
Scott

	       1994 Symposium on Volume Visualization

		 October 17-18, 1994 Washington, DC
				   
	        ====>>>>  CALL FOR VIDEO  <<<====

The Volume Visualization Symposium, sponsored by ACM-SIGGRAPH and the IEEE
Computer Society Technical Committee on Computer Graphics, seeks 
entries to its Video Session and tape.  In the Video Session authors will
present recent results shown in the video. Presented contributions will be
collected in a tape and distributed to all the participants of the symposium.

Submissions to the video session and tape should include a VHS tape
(NTSC or PAL) accompanied by a short abstract with explanatory text or
narration. Please submit, on or before September 20, 1994 to:

	Holly Rushmeier
	Rm. B-146, Bldg. 225
	NIST
	Gaithersburg, MD 20899
	Telephone: 301-975-3918
	Fax:       301-963-9137
	Email:     holly@cam.nist.gov

Please label both the videotape and its container with the contact 
person's name, affiliation, address, telephone number, title of piece,
and runtime.

Although we prefer reviewing the video clip itself, due to the short notice
we will also consider abstracts accompanied by snapshots taken from the 
video clip to be presented. Accepted contribution of the latter type will
be presented in the symposium but not included in the distributed tape.

Suggested topics include, but are not limited to:

* Volume visualization of unstructured and irregular grids.
* Discipline-specific application of volume visualization.
* Parallel and distributed volume visualization.
* Hardware and software systems.
* Analysis and control of rendering quality. 
* Volume segmentation and analysis. 
* Rendering of large datasets.
* User interfacing for volume visualization systems.
* Acceleration algorithms for volume rendering.
* Fusion and visualization of multimodal and multidimensional datasets.
* Visualization of non-scalar volumetric information.
* Modeling and realistic rendering with volumes.

Got a possible fix for this.  I often use the streamlines module and
the 'ucd particle' module animate along the streamlines (since I
wrote it (with Ian Currington)).  The behavior right now is to 
eliminate the track completely once the particle exits the domain
or reaches the end of the track.  Don't know if this helps...

that the algorithm is so difficult, it's just that the lookup table is a

The function AVSparameter_visible also does the trick. If you did this:

param = AVSadd_parameter("Filename", "string", "", "", ":");

then you can make it appear or disappear like this:

AVSparameter_visible("Filename",0); /* Disappear */
AVSparameter_visible("Filename",1); /* re-appear */

These questions have come up before, and I'm sure they will come up again. 
It seems that providing this info on-line makes a lot of sense!  It would
save the folks at AVS, Inc. lots of time in answering the same question
over and over again.  (Is anybody at avs.com listening to this???)

Actually I learned recently about ftp.avs.com (which is, of course,
different from the AVS repository at NCSC).  They have several interesting
directories (e.g., pub/express/info ), but unfortunately they fall short in
answering Jacob's questions.  However, they are good for other things.  (I
got a bug-fixed copy of the AVS executable for our Alpha, for example. 
Very helpful!)

Also, there is information at http://www.avs.com for those who can access
this.  It includes a short non-technical blurb on Express (as well as a
panoramic picture of Larry Gelberg).

Yes use AVScommand with CLI calls, such as manipulator to create widgets
or create them all and hide them using AVSparameter_visible which will
hide and re-display widgets.

You can get the name of your module in the network editor using $Module 
in the AVScommand call.  You may need to enclose the whole lot in quotes
too (which need to be escaped in C).  Eg to use the above manipulator command
with a widget Move Up send the following string to AVScommand:

"manipulator \"$Module:Move Up\" -show \n"

Check out the network files for the syntax etc of manipulator when attatching
widgets to parameters.  NEVER connect a real widget to an integer parameter!!

Hope this sheds a little more light upon things.

We are thinking of purchasing a Spaceball and are wondering about compatibility
with AVS-5. I believe that AVS no longer supports the Spaceball, however it
seems like it should be simple to write a module which reads from the Spaceball
and sends transformation parameters to the geometry viewer.  Has any one tried
this? I would be interested in hearing from any one who has experience
interfacing the Spaceball (or other such 6-dof input device) to the geometry
viewer.

Friendly Greetings to everybody!

To make 3D Viz-tools like AVS more popular at our site, I need to provide
them with

       easy access to high quality low cost color hardcopy 

(pictures look as much as possible like a photography of a 24bit display,
 but not for the price of a dye-sublimation print).

Therefore I think about buying a

       CANON CLC 350 with EFI Fiery RIP

so PLEASE if anyone can comment on this issue I would greatly appreciate to
share your experience or know how. 

I heard about another RIP called 

      colorcue  (or colorcube ?) which might be a better choice

The plotter shall be centraly operated (situated in our computer hall)
                     accessed via ethernet TCP/IP
                     robust
                     make good overhead transparencys

Thanx very much for responding

I'm looking for a graph layout toolkit to visualize meshed network.
I have already checked several layout toolkit for large DIRECTED
graph, such as xgrab, edge, daVinci, etc. Unfortunately I feel these
toolkits are not proper to show UNDIRECTED graph like meshed network
or network topology. If anybody knows any other toolkit for this,
I will be glad to see it. Any comment or also any paper related with
this matter will be greatly appreciated and recognized. Thanks
