Thank you for the response. I fully understand the position now, and retract
my previous Bah Humbug attitude. It does make sense that if one vendor
got free support on the site, the others would instantly pull their support
and the site would be high and dry.

I made second-order comments in a later post referring to profiteering by
the IAC, because I had seen no response and that "confirmed my suspicions",
but it turns out a news reader/server configuration prevented responses
from arriving in a timely manner.

Thanks for the clarification, I will continue to submit modules. Besides,
there aren't any Cray-4 binaries on the site, are there??? One day soon,
perhaps :)

Have any of the alternatives proven to be particularly wonderful
(or terrible) for you? Feedback from users would be greatly appreciated. 
A summary of replys will be posted.

Hope this question isn't insulting (nor stupid!) ...

I'm not pleased with the postscript output I get with AVS. I have tried both
the "write postscript" module (or whatever it is called) that feeds from the
the geometry viewer, and the "geom_write_postcript" (or whatever it is called)
CLI coomand.

In either case, the image on the screen (SGI) seems much better than the 
printout (HP). Now I'm no expert, but it seems that the postscript file
is just an X image. Is it possible to get a postscript file that has just 
postscript commands? (or is this a stupid question?)

It's almost impossible to convert a picture to PS with only PS
commands (unless *you* -- as in you, the program -- generated it, in
which case, you can generate PS code the same way.) But 99% of the
time, you will have to produce a PS pixmap. If you don't like AVS's PS
module, try ImageMagick (available at ftp://ftp.x.org). You will also
need Ghostscript (ftp://prep.ai.mit.edu). Among many other things,
ImageMagic lets you convert almost any format to/from any other,
including (Encapsulated) PostScript. I produce jpeg's and then simply
type

 % convert asdf.jpg asdf.eps

and voil! A pretty good quality encapsulated ps image that I can
include in my LaTeX document with \epsfbox.

Hello fellow AVS'ers!

We here at SAIC are entering the new field of oil reservoir modelling
and oil well simulation (new to us), and would greatly appreciate a
few pointers from those of you who have already done this type of
visualization.  By pointers I mean any demos and/or literature
combining AVS and the petroleum industry.  Have you had to develop
a completely independent set of tools (modules) to do your
visualization, or has the bulk been AVS supplied?  Basically, we'd
like to see what others have done, and learn from them.  Any help
would be appreciated.  Please send responses directly to me.  Thanks!

The postscript produced by the postscript module "image to postscript"
is as good as the picture on screen (or better if your screen cannot 
show colours using 24 bits). 

To verify this try: assuming that ghostscript and the PPM image tools exist

gs -sDEVICE=ppm -sOutputFile=tst.ppm tst.ps
ppmtogif tst.ppm > tst.gif

If you have an image viewer that can view .ppm or .gif you should be able
view your original image without loss of information.

Your problem is probably that the printer does not handle the postscript
good enough. If you have a color/greyscale printer you should get good 
results, but if your printer makes a monochrome version of the image you 
may get problems. 

If conversion to monochrome (dithering) is handled poorly by your printer
try to dither the image with an image processing tool. (f.ex the program xv).

Also remember that the resolution of a printer exceeds that of a computer
screen. You may get better result if you make AVS generate a postscript
version with higher resolution. To do the turn the "show image" button in 
the camera choice of geometry viewer OFF, and then increase the "width" and 
"height" of the camera. Note that AVS will ensure that "width" and "height" 
stays smaller than screen resolution if "show image" is on.

SUBJECT:  Re-organization at the IAC

Dear AVS Community,

        We are announcing an organizational change in the International AVS
Center, located at the North Carolina Supercomputing Center, a division of
MCNC.  As most of you are aware the center was founded in 1991 and David
Bennett has been the Director since that time.  David left NCSC in December
of 1994 to announce his new Virtual Environment company called Alternate 
Realities Corporation at the end of this year.  David had been half time for 
several months and has worked to transition all related activities to Chuck 
Mosher who will be the new Program Director of the IAC at NCSC.  We would like 
to thank David for his dedication, hard work, and enthusiam in building the 
International AVS Center into what is is today, and we wish him the best of 
luck in his new venture.  We also extend a Welcome to Chuck Mosher who we feel 
will take the IAC through the next phase of continued growth.  Chuck will be 
the Technical Program Co-chair at AVS '95 this year, sharing that task with 
David who will be helping him with the transition.

Chuck comes to us from Sun Microsystems, where for the past 6 years he worked 
on a variety of projects involving visualization and multimedia.  He was 
responsible for the first commerically-marketed volume renderer, Voxvu,
and worked on the SunVision product; some of whose components have now been
incorporated into AVS modules.  More recently, he was involved in the design
and implementation of the XIL imaging and XAL audio foundation libraries.
Before working at Sun, Chuck was at the Department of Radiation Oncology at
North Carolina Memorial Hospital, where he helped design and implement 3D CAD
tools for radiation therapy treatment planning.  He is excited to be working
again with the visualization community, and is looking forward to meeting many
of you at AVS '95.

Steve Thorpe has been a part of the IAC for the last 2 1/2 years and has been 
an extremely valuable asset to the AVS Community.  Steve has a strong back-
ground in the environmentally related areas of visualization, and has recently
accepted a position in NCSC's Environmental Program.  This is a nice
promotion Steve, and rewards all of his hard work in helping make the IAC 
a success.  We thank him and wish him the best of luck.  A new employee,
Mickael King, will be helping Chuck in taking over Dave's and Steve's duties.  

Michael received his undergraduate degree from North Carolina Agricultural 
and Technical State University this past December, where his major was in 
Electrical Engineering.  As an undergraduate research assistant in the Machine 
Intelligence and Power Associated Research Laboratory he has been actively 
involved in developing new ideas and concepts in such areas as Artificial 
Intelligence and Power Systems and Control.  For the past three summers he
has worked as a research for the Duke University Engineering Research Center 
for Emerging Cardiovascular Technologies.  As a research intern, Michael has 
worked directly with a variety of academic and private industry researchers 
to develop the next generation of computing tools for investigating 
cardiovascular events.  As a result of his past research experience, he adds 
three professional publications to his name.  

The IAC was initially founded for a period of three years and has delivered 
on all activities above and beyond what was hoped for in it's infancy.  
The contracts all ended September 30, 1994 and we have renewed that agreement 
for an additional three years just this week.  We have a strong core group of 
sponsors and many new ones that have joined in over the years.  We have also 
lost a few.  The current sponsors are AVS, Inc, Digital Equipment Corporation, 
Fujitsu, Hewlett-Packard Company, IBM, Kubota Graphics Technologies Inc., and 
Sun Microsystems.  Affiliates are Mobil Research and Development Corporation
and OKI Electric Industy, Co., Ltd.  Over the years we lost WaveTracer and 
Convex as sponsors, but their early help was greatly appreciated.  We hope to 
add many more over the coming years.

You can contact Chuck Mosher at chuck@ncsc.org or through the standard IAC
email at avs@ncsc.org as well as by phone at 919 248 1100.  David can still
be reached at davidb@ncsc.org and at 919 558 0060 at his new company if you 
need to contact him for personal reasons.  Steve Thorpe maintains his previous 
email of thorpe@ncsc.org, he has just moved to another department.  If you have 
any concerns or questions regarding the reorganization, you can contact either 
Jim Aucoin at AVS, Inc, 617 890 4300 or Chuck Mosher, NCSC, 919 248 9290.

Hi,
       I have some problem with avs animator.
I have a sequence of files that represent different position of a molecule 
I'd like represent and save each of them as keyframe sequence for animation. 
I try it but avs animator consider each frame as different images so it doesn't
genereate any keyframe between frames, interpolating  my key values. 
Is there any way to do it with avs or I must use another tool (like 
ImageMagick) ?
Can anyone suggest something about it?
                                         Thanks.

"Directional, Point, Bi-Directional, Spot", as displayed
on Page 5-43 of AVS User's Guide. Now, after upgrating my machine's
system, when I press the "Light" button, I only get two different
kinds of lights. They are: "Directional, Bi-DIrectional". The
spot and point lights have gone!

Could somebody give me some hints on how to get those two lights back?

Your help will be greatly appreciated!

My avs version is:
  AVS version: 5.01 (50.55 DAO)
and my unix system is:
  OSF1 V3.0 347 alpha

Help             

     I will be working with large multi-spectral data sets.   A typical data set will contain 
three dimensional information for ~200 elements.  I am looking for display software to help 
visualize the concentration information.   It would be nice to have software that could be run 
on both PC's and MAC's.  A typical data set will be on the order of 512 MBytes.  We plan to 
write the data to a CDROM.  We would prefer to transfer basic display software for both 
platforms to the same CDROM.   The data will be in a 4 dimensional array, x, y, z plus elemental 
concentration (8 bit ).  Each plane will have a maximum 256 (x) X 256 (y) X 200 (elemental).  In 
most cases, their will be far less than 200 elements analyzed.   The type of software we have in 
mind would be capable of "Slicing and dicing" through the 3 D data set.  It should provide 
multiple windows showing the different elemental concentrations cued into the fist widows view. 
 It should be able to provide raytracing (voxel raytracing) through a semitransparent parent 
volume to help visually locate the distribution of trace contaminates in the volume.  An ideal 
system would have the capability to display milti-spectral images, "false color if you will",  
indicating the apparent locations of more than one element at a time.  I have seen some software 
AVS running on a Silicon Graphics workstation that meets most of these goals.  Also spyglass has 
some of these capabilities as will. Your input as to possible software solutions would be 
greatly appreciated. In particular, any C source code that may be around, freeware or otherwise. 


Thanks

Has anyone created a module, or netwrok, that will read a file,
(1D, 3-space, n-vector) and will use this to create cylinders
to represent well-bores.  I looked at the MAPPERS directory and
didn't seem to find anything.

Thanks for the help,

-eric

Is it possible to draw arbitrary images in the graph viewer?  If not, how
do you create two dimensional images?  I've tried using the geometry viewer,
but if the user puts any Z motion on the image while he is looking at it it 
is very annoying.

Thanks.

The documentation says that you cannot change the color of the black
background but replace it with a AVS image file.

I am trying to combine a previously written Motif program with AVS, by
making the program a coroutine module.

The AVScorout_X_wait routine seems ideal for my purposes.  However, when
I call it, I get a message to FIRST call AVScorout_X_init.  There is NO 
documentation for AVScorout_X_init that I can find, and it is not in the
include files.  Anyone have a clue?

Also, any help on getting my custom color map to be acceptable to AVS would
be appreciated.  I HATE screen flashing, and I don't need lots of colors in
AVS, but need lots of gray values in my tracing program.

Could anyone please help me out with this problem:

I've been trying to write a module which takes an unspecified number of
inputs (UCD's).  I envisioned something like the geometry viewer's multiple
connection geometry input.

I tried declaring a ucd input port using the MULTIPLE flag, and then
experimented a bit with the AVSinput_changed(in_port_name, connection)
call, but I couldn't make that work.  Also, there doesn't seem to be a way
to select input values from the various possible connections.

Am I hoping for something that just isn't there, or have I missed something
along the way?  Any help or suggestions would be much appreciated.

Perspectives on Computer Vision

Presented by Azriel Rosenfeld

Wednesday, February 1, 1995
11:00 am - 5:00 pm

Computer vision is concerned with obtaining information about
 scene by computer analysis of images of that scene.  It has
applications in document processing, medicine, remote sensing,
industrial inspection, robot control and many other areas.  The
course will provide a broad introduction to the fundamental
principles of computer vision.  It will emphasize basic concepts
and techniques, and will stress intuitive understanding rather
than mathematical details.

Benefits:
This course will provide new perspectives and insights, as well
as conceptual foundations, that will be valuable.

Intended Audience:
Managers, engineers, scientists and support staff who are interested
in the basics of image computer analysis will be especially interested
in Dr. Rosenfeld's practical approach.

About the presenter:
Azriel Rosenfeld is a tenured professor and director of the Center
for Automation Research at the University of Maryland.  He is an
editor of the journal, Computer Graphics and Image Processing,
a fellow of the IEEE, a director of the Machine Vision Association
of ASME, and a past president of the International Association
for Pattern Recognition.  He has published about 20 books and
nearly 400 papers, most of them dealing with the computer analysis
of pictorial information.  Dr. Rosenfeld received his Ph.D. in
mathematics from Columbia University.

gif files are 8 bit and so inherantly poo. it might be better to try
tiffs. (you can still get compression).

just select key advance in the top left of the animator control panel.
I think this should work.

alternatively it would be dead easy to create a co routine module that
outputted the 2 filenames. but this is a little hacky.

If anyone could please help me out with this problem I would really appreciate it.

Here's what I want to do.  I have several networks that run fine, but I would like to
have them all be accessable at the same time.  I was hoping to just have all the
network modules and their displays, such as sliders and dials, etc.. be all wrapped
up into one window, so that I just have to push the dial on the data-viewer
to which ever network I want.

This is difficult to explain.  I've worked with the Create Stack and Create Page but
for some reason I just don't get it the way I want.  With more detail, this is what I
want it to look like.  When you create a stack you get a window that can be named
anything, in the data viewer. For example I want to be able to have 5 or so, created stacks named: net1, net2, net3, net4, and net5.  Ok so these now appear on the left,
fine. Now I want to be able to push any one of those buttons, and have the
necessary info. that comes with each network appear.  This way I can toggle back and forth without having to clear the network or merging netwroks.  In particular what I want to come up when I push the button, is something like a Page, from Create Page.  This page should just have the slider and input windows that the modules need to run.  I do not want the modules to appear.

I'm doing this in order to have users that are not familiar with AVS modules, be
able to run the networks.  It should just be a push of a button for non-AVS users.
Users would only have to run AVS with the option of this entire network, and just
have the data-viewer with the stacks (net1, etc.) come up.  From there they
would just click on which ever network they want without having to see/deal
with modules.

If anyone has any ideas that they would like to send my way, I would appreciate
it if you could mail me directly at:

Can't you use the geometry viewer instead of the image viewer ?

I remember I personnaly visualized some images in 3D by converting
them into a field and then visualizing the field in 3D via the
geometry-viewer.

There is a file /usr/avs/runtime/AVS.applns

if you add the paths to your Networks, start AVS and click on
AVS applications, you will get a Button which load
your Applications (not bringing up the network editor)

(I did not check in the doc if you can have your personal AVS.applns file)

the problem in doing this kind of thing is that support for "ragged"
arrays is very limited.  you can't do it (easily) with fields.  instead,
you have to go straight to geometry.

so, you will have a bunch of 1D, 3-space, n-vector clusters of data,
one for each well.  there's a pair of modules, plot_xyz and plot_xyz_color,
(at the IAC) which read in data of this form and create polyline objects.
you can then feed these to tubeness (also at IAC) to replace the line
segments with cylinders.

a slight restriction - you'll be stuck imaging 1D, 3-space,1-vector or 0-vector
data with these modules. plot_xyz_color will take a colormap and create
colored segments.

if your colors represent lithology, then you probably don't need a 256-length
colormap.  if so, you can create your own colormap and grab the module
"read colormap" (IAC) as the stock generate colormap module does strange things
to colormaps that aren't 256 items in length.

Dear AVS users:

I have a C++ application that uses Motif, and an external DBMS. I'm looking
at using AVS to handle the visualization. I have an evolving data format,
along with various kinds of metadata thet describe it and hold other system
objects. I have access to AVS, but am relatively unfamiliar with it's innards.
I'd appreciate some help with the questions posed below. Please forgive any
naivety on my part.

Questions on Using AVS:


1. Can AVS be used as a library for my application code? I am not sure I
   want to integrate my C++ code into AVS, but want to take advantage of
   AVS's capabilities to perform visualization. What would be involved to
   enable such a setup? Or rather, what is the minimal amount of code I'd
   have to write / rewrite to get my app talking to AVS?

2. Can I integrate my own modules that include Motif widgets? What happens
   between the X Event Manager and AVSs? Any problems?

3. Has anyone written modules to access a DBMS? I'm looking at AVS/SQL now, 
   but would also like to know if there are others who have written modules
   that interact with DBMSs. What are your experiences with this marriage?

4. Is there any way of catching all AVS system interactions? I'd like to 
   be able to record each user-initiated interaction (such as data select-
   ion, rendering specification, geometry re-orientation, etc.). Can int-
   erations be trapped and written to a file?



That's about it for now. Thanks in advance!

I am trying to simulate contraction/expansion of an object.  I have the
X,Y,& Z coordinates,on the surface, for the static or initial object.
However, I only have selected x,y, & z points which shows the
contraction/expansion of the object's surface.

        For example, I have 100 (X,Y,Z) points which defines the
static surface of an object.  Then I connect 10 sensors on the object's
surface to detect the dynamic (x,y,z) coordinates as the object
contracts/expands.

Question:

1) How can I simulate the contraction/expansion of the object from its
static position if I only have 10 dynamic coordinates and 100 static
coordinates?????

If you delete an object in the geometry viewer, is there a way to notify an 
upstream module that the object was deleted?  You can get the geometry viewer 
to notify if an object has been transformed or picked, but I don't know about 
deletion.

I'm asking this because I have a geometry producing upstream module that keeps 
a data structure of the objects it creates.  If the user deletes an object, 
then my module needs to know about it.

A (2nd class) solution to the problem is adding a delete function to the 
upstream module.  If the user wants to (properly) delete an object, he or she 
must use the module's delete instead of the geometry viewer's.  The module is 
still able to delete the object from the geometry viewer by calling:

	GEOMedit_visibility (*edit_list, "<object name>", -1);

Of course, this solution is bad since the user can still improperly delete an 
object.

If anybody knows of a solution (or knows there is no solution) to the original 
problem, please let me know.

a morphing question...

if you make the following assumptions, then your problem is becomes trivial:

1. you have a polyhedron object.  it is composed of vertices, faces and edges.
	the vertices are either 100 or 110 in number (not clear from your
	description).  let's say that you have 100 "static" points, 10 of which
	correspond to values returned from your sensor at time=0.

2. the topology of the object doesn't change over time.  that is, the
	ordering of edges about a face, etc. don't change as the object
	expands/contracts.

so, all you have to do is to write a coroutine which creates a polyhedron
object.  it takes an array of vertices, and info about faces.  each face has
a list of vertices which form the edges of that face.  the vertex on each face
is specified as an index into this table.

so, at each time step, you update the 10 locations in the array of vertices
and blast off a new object, in which only the vertex information changes.

easy, eh?

I won't be able to get my hands on the AVS devoper's manual until sometime

here.  

I've managed to install some modules I've compiled, but can't get the
manual pages for them to come up correctly.  (You know, when you right click
on the module button to pop up its little window, then select "view manual"
or whatever.)  I think I've got the help path in .avsrc set up properly.
What's the trick?

What you have to do is this:
 avs -reindex /pathname
where /pathname is the full name of the Directory for your new help files.
After this command is run, it will create a .topics file that it will use 
to find out which helpfiles go to what modules.  Sometimes, the helpfile 
will still not be accessible after this.  That probably means that you have
to change the formatting of your helpfile so that it looks more like the
standard helpfiles because the reindexing and .topics file is very picky
about the format you use.

Is it possible to have the geometry viewer notify an upstream module that an 
object has been deleted?

I have a suituation where a geometry producing module needs to be notified if 
the user deleted a geometry.

Please post if you have ideas.

Thanks,

Hello!

I have a question to AVS 2D-fields. I think, for AVS-perfects it is
simply to answer, but I by myself can not find a solution.
I have a 2D irregular grid. Perhaps x=1,4,8,11 and y=2,6,14
and a table of values.
Is the field-header
# AVS

ndim = 2
dim1 = 4
dim2 = 3
nspace = 2
veclen = 1
data = float
field = irregular
label = testdat

variable 1 file=./test.dat filetype=ascii skip=2

coord 1 file=./test.dat filetype=ascii
coord 2 file=./test.dat filetype=ascii skip=1
coord 3 file=./test.dat filetype=ascii skip=2

correct?

But then how I can build a network, that shows me a colored plane, the colors
interpolated between the points corresponding to the values in the table.

Any help is welcome.

Regards, Astrid Kuhr

We would like to use imageprobe and sketchROI both in imageviewer. 
The problem is that sketchROI works but changing to imageprobe via
"set pick mode"-Button doesn't work. This might be due to a synchronisation
problem in the network (input of imageprobe in the network lies before input
of sketchROI-module).
Suggestions how to use both modules in the same imageviewer are greatly
appreciated.

Thanks in advance,
Helmut

We want to mark different regions in an imageviewer-window which stand
for different classes/clusters of data. The results should be written
to a file which reflects the distribution of the different classes in
a 2D/1vector field (ASCII). Classes should have distinct numeric values.

Does anyone have experience in related problems?

Hi,

  I am relatively new to avs, and am trying to use avs to generate
tracers of particles.  Meaning that at each time step I want to connect
a line between the current position of every particle and its last
position.  But I also want the width of the line to be dependent on
certain dynamic parameters.  I was just going to continue to add
polylines to a created object of type GEOM_POLYTRI, but at least in the
developer's guide there doesn't seem to be any way to change the width
of the line.  This is in 3-d, so I was thinking of somehow integrating
the tube module into my network, though the limitations seem to imply
that this can't be used with polylines, only disjoint lines, which
considering the size of my data set I would really prefer to avoid.
  Also every new segment for every particle will almost definitely have
a different "width", meaning that I need the ability to draw a polyline
made of connecting segments with different widths.  Any help would be
greatly appreciated.
    thanks,
      Joshua Weitz

The trick is that the short help that is popped-up when you click

Hi,

We did some work (based on work by Breen, House et al.) on modeling cloth
using a coupled particle system, in our case, on a parallel machine.

You can see the latest Breen/House paper in the proceedings of SIGGRAPH
'94. This will probably give you the starting points you require.

If you need any more details, please let me know,
	-G.

       USGS DIGITAL MAPPING AND IMAGE DATA IS ON THE INTERNET

   The U.S. Geological Survey USGS is making information about its vast 
collection of digital mapping and image data accessible by the public via 
the Internet. In a ceremony at USGS Headquarters in Reston, Virginia, 
today, USGS Director Gordon Eaton clicked a "mouse" on an image of a 
ribbon to open the USGS Node of the National Geospatial Data Clearinghouse, 
part of the National Information Infrastructure. Said Director Eaton, 
"USGS holds the premier collection of Federal geospatial data. We are 
committed to making that resource easily available to everyone."

   The opening of the Clearinghouse is important to the growing community 
of Geographic Information System (GIS) users. GIS, which allows drawing 
and analyzing maps with a computer, has many commercial and environmental 
applications. The availability of accurate data -- particularly digital 
versions of USGS maps -- is critical to the success of GIS.

   Internet users with one of the popular software applications such as 
Mosaic can browse descriptions of the different USGS data collections. 
When a user finds a data set of particular interest, they can click on 
a symbol and see more details, including instructions on how to order it. 
Alternately, keywords and latitude/longitude bounds can be used in a 
powerful searching mode to scan the entire USGS collection. Some of the 
data sets are on-line for immediate transfer. The Clearinghouse address is:
             <URL:http://nsdi.usgs.gov/nsdi>

   The National Geospatial Data Clearinghouse is part of a government-wide 
effort, led by the Federal Geographic Data Committee, to make all Federal 
geospatial data available to the public.

Hi.

There are plenty of papers in SIGGRAPH and IEEE journals on Computer Graphics
on cloth modeling and animation. I would suggest you start with the older
journals (about '88) and work from there on up to the present. The older
journals may be a bit old but I have found them usefull as a starting point.

By the way, the e-mail address above didn't work. My mail was returned.

Go and have look at the avs-ftp server:

avs.ncsc.org (128.109.178.23)

or via WWW: http://avs.ncsc.org/HTML/ITD/IAC/IAC.html

I do not remember in which category I found it but there is a module
called tubeness which convert any line into a tube :)

Your field should be:
# AVS Field File
#
ndim = 2
dim1 = 4
dim2 = 3
nspace = 2
veclen = 1
data = float
field = irregular
label = testdat
variable 1 file=./test.dat filetype=ascii skip=1 offset=2 stride=3
coord 1 file=./test.dat filetype=ascii skip=1 offset=0 stride=3
coord 2 file=./test.dat filetype=ascii skip=1 offset=1 stride=3

This means the data file test.dat should be:
X     Y    Value -Header line
1     2    10
4     2    12
8     2    14
11    2    16

4     6    22
8     6    24
11    6    26
1     14   0
4     14   5
8     14   10
11    14   15

Skip = number of lines to skip from top of file
offset = number of values to ignore on the first data line
stride = how many values you have to read to get to the
         next valid number.

A Sample netowrk for displaying this field is:

Those of us who have ever recorded an animation from AVS to video tape
(interlaced video, like a normal old VHS) are painfully aware of this
missing feature in AVS. It's been a missing feature for close to 5 years
now, that's how long ago I first whined about it, back when AVS became
a Stardent product instead of a Stellar product.

Here's a good poke in the ribs for the AVS developers: Iris Explorer supports
line width... (I only make such jabs because I used to do it to the
Explorer developers too, a little competetion can be good for the consumer)

Anyway, if you're looking in 3 space, you'll have to end up making them
cylinders. If you'll always be looking from one direction, you could make
them rectangles by taking the slope of the line segment, and computing 
the four corners. Of course, the tube module is already built-in to avs,
and there are variations of it at the IAC, so if expediency is more important
than computational efficiency, tube is the way to go.

I have a question on why the simple example "threshold" module
beginning on page C-4 of the AVS 5 Developer's Guide works...

In description routine of this module, the input and output field
ports are created, and then the following is executed:
    AVSinitialize_output(in_port, out_port);
which allocates space for the output field matching the input field.

The question is: why does this work? What if you disconnect the input
to the module, and hook it up to something outputting a larger field?
My understanding of the description function is that it's only called
once when the module is placed in the network, so the output field
would never change size based on changing input fields. Am I mistaken,
and if so, when exactly does the description routine get called? If
it's called more than once, isn't there a memory leak because the
previous output field never got freed?

The way I think the example should work is that at the beginning of
the computation routine, you should check if there's an existing
output field, and if there is, free it. Then use
AVSinitialize_output() to allocate a new one matching the input field.

So why does the example work?

Thanks!		Mike Blackwell		mkb@cs.cmu.edu

Hi,
  Is it possible to use the GEOMadd_polytriangle_vertex_trans function
call to create semi-transparent lines... not surfaces, but lines?
Essentially I am using a coloring scheme which creates a bunch of black
lines under some circumstances and I want to turn those transparent so
I can look at the usefull information.  But when I use the
GEOMadd_poltriangle_vertex_trans function call using the appropriate values for
n and alloc on each ith polyline within my object, it crashes on the first
polyline.  Any advice would be appreciated :)

Is there a way to create and delete annotations/labels in 
ImageViewer from an upstream module?  I can only create
labels, but don't know how to delete them.

My upstream module sends an image to ImageViewer through an
output port, and it also writes labels on the image by calling
CLI commands, such as image_label_name and image_label_transformation.
The problem is that I cannot find a way to delete those labels
once they are created.  Even the upstream module sends a second
image to ImagesViewer, those old labels are still there.
Your help is highly appreciately.

Hi everyone,
    I am very new to AVS and have a general question to all the gurus out there.  I am writing a module which has a parameter defined as radio buttons. Now I have three/four choices. Now these choices have different parameters which are relevant only to a particular choice I have picked. I can use  "-hide" to hide irrelavant parameters alright. But this only happens in 
the compute procedure after I have connected all the required inputs and the module starts execution. What I want is that when I pull down the module onto the workspace, the parameters should show or hide according to the choice selected without the module yet connected to the inputs or starting real execution. 

I have looked into the manual and also the examples but all of this is done in the compute procedure. Because of this restriction I have to show ALL the parameters in the initial screen including the ones which are irrelavant to the choice picked. This also causes confusion to those using the module and do not know which other parameters belong to a particular choice unless they start executing the module.

Is there a way I can do this without having a dummy parameter defined as "go" which really starts the actual computations. All other changes in parameters make the output unchanged!

Thanks to anyone who can help me out.

> The question is: why does this work?

The structure of a field contains pointers. One of these points to the
data. So when the output field is "allocated" it is just the structure
that is allocated, e.g. some memory for storing the pointers. These will
then be copied from the input-field to the output-field during execution.
So the size of the input field does not matter.

Well, memory management is up to you. The Threshold module only takes a
field as input, thresholds it and outputs the result. It is up to you
to free the memory allocated for the previous one, if required.
Moreover, the threshold module only copies pointer from the input
structure to the output one (that's why they must be the same), so no
allocated memory is leaked, only transferred.

You can get the functions provided by the middle mouse button

Dear Mr. Walker,

I had this problem, too. If you have a look on fin.fld which contains
the header to describe the field data, you will notice that the dimensions
are 10x10x8 whereas the data in fact is 10x8x8 (according to the
workbook description). Just replace dim2 = 10 by dim2 = 8.

We have AVS 5.01 running on a DEC Alpha. As we are very unpleased with the 
3D bar chart module we got through ftp the module city_scape.

After compiling and linking we try to run the module in the network 
city_scape.net. Unfortunately we get the following error message:

Fatal: Function: FLOWexec_remote_module
Protocol failure:Assuming model died. 

The AVS hotline said it might be because we have OSF Ver. 2.0 and it
should work with AVS 5.02. We tried this out and: we get the same errors. 

Any help is really appreciated !
