I'm trying to find a way to run AVS without displaying anything, so that
I can set up a script to read in data, render, and write the geom file
without me having to sit there waiting for it.  (I use the software
renderer, unfortunately.)  I seem to recall reading something here a
while back about a -nodisplay flag when booting AVS, or perhaps
something in the CLI.  Does anyone know of something like this?

Steve,
Yes, use "-nodisplay" on the AVS command line.  Our experience on a
GS-1000/2000 is that you also must specify "-display some-hostname:0" where
some-host is used as a dummy X display that must have X running on server
":0".  This was true even if the network running in this "batch" mode was
not displaying ANYTHING!  I'm interested if there is another way or if
later versions of AVS behave differently.  (Funny - neither the online nor
hardcopy doc on my DEC Alpha/OSF1 version of AVS mention "-nodisplay", but
it is accepted as a valid option!)

Dear AVS users,

Recently, I am considering to run avs on different systems at the same time.
Is there any method to run the computational intensive work on Silicon Graphics,
and the display processing work on the SPARC IPX workstations?  If you have
any idea about this, please follow-up, or send email to me.  Any advice will
be greatly appreciated. 

Many thanks!!

Hi Everyone,

I'm desperately looking for the source code of an AVS module called
'image viewer'. People here at the lab have trouble finding it and
avs.ncsc.org only has source codes of newly developed AVS modules.
Can someone send me the code I need or can someone tell me where I
can find this souce code? If so, please send me an E-mail at the
address above.

Thanx!

Alex.

Hi T. J.
   I do exactly what you are thinking of doing all the time.  I run part
of my modules on a DEC Alpha processor and part on a DEC Ultrix machine 
(I have also used a KPC Titan in this manner).  If you use remote modules
to do the heavy processing (up to the point of actual geometry creation)
and then the other machine to render the geometries, it seems to work
fairly well.  The remote machine doesn't actually run AVS, just the modules

you want to run remotely.  For the best performance you want to minimize
the amount of data that you need to transfer from one place to the other.


Hope this helps

Dear AVS User,

The IAC has been soliciting articles for the Summer 1994 issue
of AVS Network News, which is to hit the streets around late
July or so.

(If you would like to subscribe, please email avsemail@ncsc.org, to
receive an automated reply with info on how to join the International
AVS Users Group.  Please do so to help support the ongoing IAC
activities).

Summer 1994 AVS Net News submissions are due at IAC Monday 6/20/94
				                    --------------

Please consider contributing to this or a future issue of AVS Network
News.

There has been a growing interest by AVS users in publishing articles
for this magazine, which has resulted in an increasing number of
pieces submitted.  We generally try to include as many submitted pieces as
possible in each magazine, although please be advised that quite possibly
will not be able to include every submission in that issue.  However 
for any pieces not included, there is a good chance of inclusion in
a future issue.  Factors to be considered in making the tough decision
about which pieces to include are 

	1) level of interest by the general AVS User 
	   community in the topic[s] covered in your article.

	2) size of the article (more that about 10-15K of text 
	   can take up a LOT of an issue, so please try to keep 
	   submissions to this length or shorter), and 

	3) date of submission (the earlier the better) 

Note:  authors should include all trademarks, and copyrights
associated with their submission.  They should also
list all 3rd party hardware/software listed in their article.  This
can be included on a separate unformatted sheet at the end of the
article.

Also, please feel free to give me a call at (919) 248-1161
if you have any questions or thoughts about AVS Network News.

Thank you very much for your interest in contributing.  Your work
can make a very valuble contribution to the Scientific Visualization 
community worldwide. 

Hope to see you at AVS '94!

Unfortunately, the "image viewer" is a "built-in" module - that is, 
it is linked directly into the AVS kernel, so the source code for
it (a) is only delivered to source code customers of AVS (and there are
not that many of them!) and (b) probably wouldn't help you that much
since you couldn't modify, relink, and run it as a separate module.

What are you trying to accomplish that you feel you need the source
code for?

I am new to avs.  If the answers to questions below are in faqs, please
let me know too.

1. How do I plot 2d vector fields and streamlines?  The module
   vec2_to_vec3 dresses up a 2d vector field for hedgehog but is
   still not exactly what I want.

2. Is there a way to specify the exact location for a point or plane
   as input to hedgehog and streamline?  Right now one can move
   the sampler point or plane in the geometry viewer by mouse but
   is very hard to get to exact locations that way  (e.g., the plane
   z=0).

3. A related question on moving a point or plane by geometry viewer:
   how do one display its location in text on the window while the
   object is moving.

4. In using the integer module to control the slice plane for
   the slicers, I find it useful to have the integer value
   displayed automatically in the title of a window of the image viewer
   as I change the integer.  How do I do that?

5. How do I specify the choice parameter port (I,J,K) for the orthogonal
   slicer?  I already tried oneshot,tristate,...

Thanks, Ken

Example 1:

A program (C or Lisp) that calls the edge detector module, supplies it with an

Example 2:

A program that calls the isosurface (or ip contour) module and gets back a
representation of the surfaces (or contours).

If the answers are in the AVS developer's guide, let me know.  I just haven't

Yes, we run AVS on an HP 720 and often when the console is in use I
end up sitting at a PC with an X server.

I must say that sitting at the console is mighty preferable, but I think
this is true whether the remote X server is on a PC or on something like
a Sun or DECstation.  The graphics card in the HP is a CRX-24 and AVS is
(understandably) nicer when using it than when remotely displaying.

That said, however, I find the PC based X to be OK as much as anything.
We run eXceed under DOS, on a 66 MHz machine with a 17 in monitor at
1024x768 I think and this is perfectly nice.  I think it works better than
any of the other X servers I have used, ie, under Windoze, or the smaller
X packages out there.  I don't know what kind of memory it needs - if
you want me to I can check next time...

Another option for X on a PC is Linux, which we run a lot around here but
I don't have much firsthand experience with it for AVS displaying.  But
without question you want a capable PC if you run X either way.

Hope that helps without being longwinded  :)

Hi all (especially Ken Yip),

  I have used this technique often to input exact points for the
sample locations for the hog and streamline modules.  What you 
need to do is create a field containing the locations, the pass it
in to the sampler port.  Here is an example of the header file
for the 'read field' module:


%more seed.fld
# AVS field file
#    seed locations for the particle advector
#
ndim=1
dim1=19
nspace=3
veclen=1
data=float
field=irregular

I don't think the data vector is necessary, but I included it anyway in
the sample field.  You could accomplish the same thing with a custom
module that created a  "1d 3space irregular float" field from a set of
typein values or in a file (it should be easy to write a module like that, 
but the 'read field' module does it already.)


Hope this helps

Summary: need to extract scaling information
Keyword: AVS, geometrical transformations


Hi all (hopefully Jeff Vroom or Larry Gelberg),
  Have encountered a problem to which I can't find an answer.
Here goes...
I'm trying to annotate a display with a scaling vector.  I don't
want this vector to move with respect to the display window
so I use the GEOMedit_transform_mode()  call to set the 
transformation mode to "locked".  This fixes the annotation
with respect to the window, but causes a couple of problems.
My displayed vector is then in window coordinates and what 
I want is to display it with the same scaling as the vectors
in a 'hog' type of display.  I can force this matching when 
the annotation is first created, but if the displayed object is
scaled through the geometry viewer, the annotation vector
is not affected (due to the 'locked' transformation mode).
  I need to extract the scaling (really only the x-dimension 
scaling) from the transformation matrix of the "top" object, 
then unlock the annotation vector, apply the scaling and 
relock the annotation vector.  Has anyone done this type of
extraction (is there a utility routine to extract scaling 
values from transformation matrices?)


I'd appreciate any input/info...

I'm trying to write a module that 'tubes' a disjoint line. 

I want a module that can create several lines, each with a different
controllable width. 

I've collected the 'tubeness' module from the ncsc site, and it 
looks like the right thing (Thankyou Wes for commenting your code)
Unfortunately, it died on me! I'm running AVS on a Sparc10.

I'd appreciate some help with either getting this module working,
or the vector maths needed to create a prism, given a disjoint line.

thanks in advance.

David & Vinod,

This module should do the trick:

Name        : glue            Version      : 1.000     Mod Number : 1612
Author      : James Pipe, University of Michigan Medical School
Submitted   : 04/10/93        Last Updated : 04/10/93  Language   : FORTRAN
Module path : avs.ncsc.org:avs_modules/mappers/glue
Ported to   : IBM Kubota
Description : Continually pastes on incoming data onto the end of a
              growing output data set - always checking to make sure that
              the dimension lengths of the input and output data sets are
              identical EXCEPT for the dimension in which the glue
              operation is proceeding (also checks vector lengths). The
              parameter 'total sets' is used ONLY for reporting the total
              number of data sets glued together in the current output
              data set - changing its value manually will do nothing.

Good luck with it.

-Steve

   Hello,

   We are trying to import some images on AVS 5.01 (Sparc
   Sun-OS_4.1.3), it can be almost in any format (eps, tiff, giff).
   We want to include our logo for a demo. We have the logo on
   various PC formats, and can also convert it to various bitmap
   formats.

   I know that at avs.ncsc.org there are various modules that can
   read eps files, but the problem I have is that to make them run
   I need the libraries sdsc and im. The first one I already have
   it, but the the tar file where the second one seems to be is 11
   Mbytes big, and I don't have direct FTP access.

   Are there any other modules which do not require those libraries
   to read an image? or can I find the second library in any
   smaller file?

    Thanks in advance.

    Agustin.

At the ftp site at ncsc there is a bianry of imconv.sun.exe which will 
run on the sun. You can use this to convert the images either as part of the 
read_any_image module, or as stand alone command line converter to avs.x 
images, for use with the read image module. (Binary ftp imconv.sun.exe
and run it with -help option for the right details on what it will do.)
Alternately, you could use the ImageMagick conversion tools which are
available through gnu (You could use archie to find exactly where).
Another option is the PBM+ package which has quite a lot of conversion
options in it. Again, try archie to see where it is on the net.

Has anyone here used the Keyframe Animator?  I'm a beginner to it and
am having a hell of a time getting it to preserve the scaling
information on my objects.  I'm trying to animate the top-level object,
which always needs to be scaled along the z-axis to preserve the proper
aspect ratio.  *Anytime* I save a keyframe, the next time I call the
frame back, the z-scaling is back to 1.  I've tried saving keyframes
with and without the SCALE transformation button selected, but either
way the Keyframe Animator refuses to preserve the scale factor of my
object.

Does anyone know what my problem might be?

Thanks,

The module at the IAC ftp site
  mappers/ucd_cell_geom
allows cell hi-light, selection, by mouse clicking,
and editing the node positions of cells by
interactive dragging. It would be a simple addition
to this module to also allow changing node values
as well as coordinate position.

Hi AVS'ers

I'm trying to write a concept demonstrator, and it was suggested that a
fly-through demo would look really good on video.

I heard rumour that someone has done some 'flying' work, where the
zooming and rotating is done automatically, rather than by hand using the
mouse.

Now, the acid test for a flight path is to get it to fly through the inside
of the teapot!

Please email me as well as posting.

I agree. We use Explorer at the University of Guelph, a nearby University uses
AVS, and it would be nice to know which one is "better" for "which applications".

I would definitely like to see such a BOF.

the first rev of the module had a stupid programming error in
it.  i think it had to do with an errant pointer when color info
is processed, or when color info is absent.  i can't remember.
anyway, i fixed it and it works great for me.  chances are, i spaced
out updating the iac site.  i'll double check and get back with you.

there are plenty of volume rendering modules, some that come with the system
and others available at the IAC site.  grep for volume in the catalog listing.

marching cubes is NOT volume rendering.  it is a technique for visualizing,
ie, an algorithm which constructs a geometric representation of an abstract
concept -- a 3d contour.

i did submit a marching cubes module to the IAC sometime last year, but
i don't know if it ever showed up.  i believe there is another one at the
IAC from some folks in the PRC.

I am sure this has been brought up many times, but I missed
them, so here goes:

I need a module that will place spheres at each vertex and cylinders
between vertices.  I could use two modules separately, sphere_to_geom
and cylinders, but I would prefer to use one so that changes and
manipulations are much easier.  I tried read_shak, but it doesn't
compile on my system, stardent 3000.

Hi all,

We make a program that produces 3D models from photographs.
To make a 3D model of an object or scene, you take
overlapping pairs of photos, digitize them, read them into
our program, trace the features that you want in your model,
and hit the *Solve* button.  After a few minutes an accurate
xyz coordinate will be produced for every marked point.  You
can export the models as 3D DXF and use them in CAD or other
graphics software.  If anyone is interested I'll be happy to
send details.

------------
Is there any way to do transparent spheres with AVS 4.0 (SGI) ?

The vertex transparency calls appear to be supported only for
polyhedron and polytri objects.
-------------
Two ways:
>From the geom viewer, edit properties of the object and use the transparency slider.

In code:
Use GEOMcreate_sphere to get the geometry going. Then use GEOMedit_properties 
to set the alpha to whatever you need. The last argument to GEOMedit_properties is
an array of three -1's, BTW.

Also, transparency of spheres on AVS on the SGI platform behaves oddly--- you get
weird effects. To get aroud this, you have to select software renderer instead of hardware
from the geom viewer module. It's slow but correct.

Maybe all the previously mentioned groups could be joined by others involved
in developing things to give a short description, and then more of an informal
panel type session ???

Thoughts ? I think this would be of interest to many people and users of
MVEs, but perhaps I'm biased - ARE there many people who would want to attend a 
panel-type thing where people from all the main groups could discuss in general
terms how they see things going, and not just specifically talk about their
own product ? Would anyone from the groups be interested in doing this ?

Hi Gordon,

I think you have a great idea. But if you can't get any commitments from the 
MVE developers why not have an informal panel-type thing where some power 
users of one or more MVE's discuss their work, views etc.? Perhaps a couple 
of workstations could be on hand for demos. I think many people would attend, 
including the developers :-).

Omer

Hello,

As per a previous suggestion, I am trying to generate a geometry consisting
of several hundred ellipsoids of with different shapes.  I assume it is
possible to create one geometry object consisting of one sphere then apply
a transformation matrix to this one sphere.   This would result in several
hundred separate geometry objects.  Is it possible to apply separate trans-
formations to each sphere, and create ONE object consisting of all the
resulting ellipsoids?  If so, how?

Thanks,

   -Tim

In this example, I have one socket connection called "sock". The 
event_wait will return if any ONE of the AVS inputs have changed or if 
data has arrived on the socket. For multiple sockets, just use FD_SET more 
than once. Of course the event wait will return for any ONE of the possible 
events, so you'll have to do your own processing to decide if all 4 
inputs have changed.


	/*===========Code Fragment=================================*/
	fd_set readfds, writefds, exceptfds;
	int mask, sock;

	FD_ZERO(&readfds);
	FD_ZERO(&writefds);
	FD_ZERO(&exceptfds);

	while (1) {
		mask = COROUT_WAIT;
		if (sock > 0) FD_SET(sock,&readfds);
		AVScorout_event_wait(getdtablesize(),&readfds,&writefds,&exceptfds,
			NULL,&mask);

		/* If data has arrived on the socket, do something with it */
		if (sock > 0 && FD_ISSET(sock,&readfds)) {
			......
		}

		/* If some AVS parameters have been changed, figure them out */
		if (mask) {
			AVScorout_input(....);
		}
	}
	/*===========End of Code Fragment==========================*/

If you're just dealing with AVS inputs/parameters, the usual 
AVScorout_wait will work fine, if you structure your event loop with
some flags to check for all four things to wait for.

Also, the AVSparameter_changed and AVSinput_changed functions can tell 
you if parameters/inputs have changed, although I haven't tried them in
a coroutine they should work.

sdscconfig.h (which is not even close to where the README file says it will
be).  To get that to run, I need to select or create a configuration
for the following:
  CHAR_SIZE, SHORT_SIZE, INT_SIZE, LONG_SIZE, and FLOAT_TYPE.
My guesses for these would be 8, 32, 64, 128, IEEE_FLOAT, but
I'm just making educated guesses.

Any tips would be most welcome.

One way, which involves some module writing, probably, is to take three

Keywords: SIGGRAPH panel visual programming
X-Newsreader: NN version 6.5.0 #1 (NOV)


For What It's Worth, I pitched a proposal for an offical Panel at SIGGRAPH
entitled: "When and How is Data-Flow Visual Programming Useful?" but it was
not accepted.  The presenters were to be myself, Phillip J. Mercurio of
the Neursciences Institute (formerly of the San Diego Supercomputing Center
Visualization Lab) and Stephen H. Price of Rice University (formerly of
Lom Linda University Medical School).  The panels chairman, Mike Keeler of
SGI, was pushing for us, but the committee out-voted him.  He said they
wanted more leading edge topics.  I asked "like what?" and he said, "VR."

Here was the panel proposal:

    Data-flow visual programming is a method for software development in
    which the process of text-editing of source code in a computer
    language is replaced by a process of configuring relationships
    between software components by placing them in a visual field on the
    screen and interconnecting them with a mouse (or other pointing
    device).  Sometimes this new method can provide benefits such as
    rapid prototyping, code reusability, ease of testing, run-time
    reconfigurability, and ease of porting -- but only if the visual
    programming interface is robust, flexible and extensible enough for
    the job at hand.  All of the panelists have either implemented
    software projects using both methods, or have thoroghly examined
    both methods for project use, and will debate the relative merits of
    each.

We planned to talk about both AVS and Iris Explorer.

It is still possible to get a room and and a kiosk posting for a "birds
of a feather" session at SIGGRAPH; contact conference management at
(312) 321-6830 for info.  And be sure to tell anyone who will listen that
they should've taken our panel proposal!  (Maybe it will make a difference
next year.)

Has anybody else run into something similar or knows a fix?

I am new in this net newsgroup and my questions may be naive. Anyway, they trouble me a lot and I am asking help from your AVS hackers.
Basically, my problem is like this: I wrote a module and it run
correctly. Now I need to add a few more parameters to the module computation function as its parameter inputs (not creating any additional input ports).
I simply add the parameters to the computation function and declare them in
the  module description function part and then did nothing to the parameters.
The input and output ports are identical as the were. The module passed the compiling. The problem comes up when I connect it with other modules. I 
always get the message "Protocal failure: Assuming module dies". I did not
change its input and output ports and these parameters are simply declared and
are not used at all in the module.  What does really go wrong with my module?

Your help is greatly appreciated!

OK - `hands up' those who,
	a) would be interested in attending such a thing,
	b) know how to go about setting up anything of the kind at SIGGRAPH,
	c) are (other) volunteers for organising (other than me :-),
	d) are developers who would be interested (and perhaps talk ?),
	e) would be prepared to give demos, machine loans, people to talk etc...,
	f) have any other suggestions....

`hands up' should probably be emailing me at gordonc@epcc.ed.ac.uk, or posting
news.

At the moment only about four or so people have said anything, which is probably
not enough ;-}

I'm try to do morphological operations using AVS and
I'm trying to understand the mtables. I can't find any
documentation on how the mtables "work". The man page
describes the header - but what about the 1D byte stream?

I'm specifically, trying to figure out the CONVEX_HULL op 
which does not seem to work symmetrically.

Should I be looking in a manual other than the
Module Reference, User's Guide, or Developer's Guide?
Is there some documentation somewhere else?

Anyway help or comments would be appreciated.
Thanks,

I found that you couldn't use AVSadd_parameter if you wanted to create
a float parameter. You HAVE to use AVSadd_float_parameter instead, as
it (presumably) deals with memory allocation properly. This may help you.
failing that, try adding the parameters one at a time.

If someone pulls a BOF together, please do let me know.  I'll be there from Monday evening
through Thursday evening and at least three of the other Explorer developers will be there most
of the week as well.  Since most of the people who have developed these packages - Explorer,
AVS, DX, Khoros - know each other already, it could be somewhat fun (heck, we always enjoy
these kinds of conversations in private anyway).

I believe there is an Explorer user's group meeting scheduled for sometime Wednesday
evening - stop by the SGI booth for a flyer containing details.

The burning question is: will there ever be a Khoros T-shirt?

Hi Everyone...

I am in a band call A.M. Prophecy.  We are a rock band and we currently have a 
CD out in local record stores.  We are based in State College, PA...Home of 
Penn State University (Wow?!).  Anyway, we are making another CD in the fall 
and I am very interested in using some really awesome computer graphics. We 
are also looking for a logo for the band name.

I have some ideas now, but I would be extremely interested in talking with 
some creative computer artists.  About the only compensation we could offer 
would be credit in the CD booklet and some free CD's...  

Anybody who is interested in giving it a go please send me some E-Mail...I 
check it very often.

Chris

PS: I would like to get started learning to use some of the graphics software 
out there..If somebody could point me in the right direction I would really 
appreciate it!  Thanks Again.

I would like to "scroll" through a very LARGE amount of time series data
with the graph viewer or some other module.  By LARGE I mean something that
will not fit into virtual memory.  So far I have a read data module 
that feeds successive overlapping windows (90+ percent overlap) of about 1000
data points to the graph viewer.  This is very slow.  Also, instead of
"scrolling" it's more like "flashing."  Is there a way to speed
this up or has anyone written a fast module to do this?

I am new to avs, but my present impression is that it is designed to do
complicated things to small to moderate amounts of data but not designed
to do simple fast things to large amounts of data.  Do I have the right
impression?

I am trying to run a network (it ist not important which components I use)
and an UCD file (node data only) on a hp 701 or
a Cray Ymp with AVS version 5.01.
The following things occurred:

- when generating the network and working immediately after the generation 
with it, everything seems to work normally.
- after saving  the network and re-reading it (READ_network) the following
error appears:
         Function: FLOWexec_remote_module
         Protocol failure: Assuming module died
         ....
   * choosing now "RESTART_SAME" leads again to the error,
   * choosing "RESTART" and reading afterwards the UCD-data-file by
     "read ucd" works without error. But in the ucd-cell-color module
     the (in the geometry viewer) displayed values are first incorrect.
     Changing to another data set (e.g. from density to veloci_u) cures this.
     Even by choosing now the density again, I get the right graph. After
     this "procedure" everything seems to work normally again. (until the
     next "READ_network").

Can anybody help? (If neccessary it is no problem to mail the data file and
the network).

Thanks in advance

Dear,

We currently (try to) run AVS 5.01 on a SUN Sparc10 Model 42 (2 processors) GT,
operating system Solaris 2.3.
When running the selftest script $AVS_HOME/test/RUNME the following happens:

At first the following messages appear several times:
	gterror-5: cannot allocate Z-buffer
	gterror-13: cannot allocate double buffer
Next thing that happens is the Xserver hangs or the machine crashes (kernel
faults). ... :-(

Somebody from SUN was friendly enough to tell us that the GT-driver does not
support multiprocessing systems (we still hope he ment "not yet"), so we take
out one of the processors to see what happens:

       gterror-5: cannot allocate Z-buffer
	gterror-13: cannot allocate double buffer  
	Next thing that happens is the Xserver hangs. ...  >:-(

Can anybody having experience with AVS and/or SUN GT's help us out or give us
some hints.

Thanks in advance,
Koen Janssens.

I am looking for some help on how to quickly find the closest
real node in a UCD structure to an arbitrarily chosen point.
In the AVS user's guide, it briefly mentions block tables,
which subdivide the data into regions that are easier to
search.  I am not sure if this is the answer, but it sounds 
helpful.  If anyone has an algorithm or module for creating/using
block tables, or for finding the nearest node, I'd appreciate
seeing it.

I need this capability because I want to create a module similar
UCD plot, but instaed of retrieving the values along a line, I
want to get the values along a circle or arc.

Any suggestions would be appreciated.

Thanks

Hi - thanks to everyone for responding to the idea of an informal panel
SIG at SIGGRAPH, based on trying to draw all those working on and with
MVEs (Modular Visualisation Environments like AVS, Explorer, apE, Data
Explorer, Khoros etc..) together to talk about current work, and future
directions.

I think that enough people have expressed an interest in seeing such a
thing, so I've decided to go ahead and try and put something together
(fingers crossed !).

I hope it will prove a good forum for users to meet with the people
developing the systems, and that this might prove useful for both
groups. I've had informal feedback from several developers, but IF YOU
ARE FROM ANY OF THE VENDORS of dataflow MVE-type systems, or have been
involved in their development at some time, then please get in touch,
as it would be nice to see you there. (Thanks to the Khoros people for
responding - its a pity that they can't be there...)

If ANYONE has any comments on the sorts of things they'd like to do,
talk about, or whatever, then also please get in touch. I think it
would be good if the thing was as non-vendor-specific as possible to
give the people a chance to chat about the things they see or want to
see.

I'll try and get a room organised, together with a time (again, if you

further details soon.....

In the meantime, some ideas for the meeting are below. Any feedback
would be most welcome,

Many thanks,

P.S. Apologies to those who cannot attend for wasting bandwidth. However,
I'm thinking that it may perhaps be possible to record what goes on,
and distribute this afterwards (if anyone turns up, and it works!).
Thoughts ?

Proposed SIGGRAPH MVE Meeting 

I propose that we do something informal like the following :

	1. Developers of MVEs (Past and Present !)
	------------------------------------------
	* Have a brief introduction of some of the people there
		( I hope we have quite a few people who are working, or have
		worked on developing MVEs in the past)

	* Let the relevant people *briefly* talk about their company's
		product ( this is useful in letting people know
		what is available, but I don't really want this to drag on !)

	* Each of the developer-y people might want to briefly state what
		they see of as the future of MVEs (in general terms)

	2. Informal Panel/Discussion
	----------------------------
	* Quick summary of what people in the audience are interested in,
		and their backgrounds

	* General questions and discussion between all those present on the
		present and future of data-flow toolkits, MVEs etc etc..
		I hope that this bit should take up the biggest proportion
		of the time. It could/should include things like :
			- what users want
			- what users can and can't do
			- what users like/dislike/use/don't use
			- how to make things portable
			- how to affect the future development 
			- advantages and limitations of MVEs
			- futures - parallel extensions/integration ?etc etc..

	3. Who's Best Discussion Between Developers 
	-------------------------------------------
		(only joking :-)))

Note that I don't think concentrating on individual products TOO much
will be useful, as there are SIGs for the specific products at this
SIGGRAPH and Vis' 94. I hope this sort of thing would be useful for
users and developers alike.

What does everyone think ? At present I am looking for :

	* Volunteers from the developer side of things ?
	* Comments on structure
	* Recommendations for a time/place
	* Expressions of interest :-)

Subject: help for contour to postscript, isolines
Message-ID: <1994Jun27.113324.1365@ibr.cs.tu-bs.de>

Hello,

I've some problems with the contour to postscript module. It stops or
breaks down after ten or sometime after hundred images without an
error message.

I produce a series of pictures for a video with an flow-simulation module.
For showing some isolines of the flow, I use the contour to postscript module,
connected to the output of an orthogonal slicer Module.

When I compile it first I got the following error messages (on a CONVEX C2):

     make -f Makefile_u
     /bin/cc -g -fi -tm c2 -float sp_const -string read_write -O1 -I. 
       -I/usr/avs/include   -c cont2post_u.c
     cc: Warning on line 180 of cont2post_u.c: actual and formal point 
       to different types
     cc: Warning on line 193 of cont2post_u.c warning: integer argument #2 
       lacks c ast to pointer
     cc: Warning on line 381 of cont2post_u.c: actual and formal point to 
       differen t t ypes
     /bin/cc -g -fi -tm c2 -float sp_const -string read_write -O1 -I. 
       -I/usr/avs/i ncl ude   -o cont2post_u cont2post_u.o -L/usr/avs/lib 
       -lflow_c -lgeom -lutil -lm
     strip cont2post_u

The problem in line 180 was, that the allocated memory could not be freed
again, so after a lot of pictures there was no hostmemory left.
In line 180 I added an cast operator:
     >     AVSfield_free((AVSfield *)IrFld);

Then, the first errormessage was gone, and it runs better, but now, it
stops again without error message.

The parameters I use are the following:

     min/max scale, 16 levels, min = 0.0, max = 0.6

The statistics of the momentary input field (from orthogonal slicer) are:
     Dimensions: 33  51
     Min: 0.0290; Max: 0.4786; Mean: 0.2281 

I use Version: 1.000 Last Updated : 02/11/93. with AVS 5.0 on a CONVEX C2.

Please help me! In fluid dynamics, isolines are very importend to show
the behaviour of a flow and I have to generate many more images with 
isolines now and in the future. 
 
Does anybody now some other modules, that I can use for visualisation of
isolines in a 3D-rectilinear!! field? 

Thanks in advance,

Hi,

	Does anybody know how to drag out a rubberband box on the geometry
viewer. We have a 2D map of the UK, with data spread across it, displayed in
3D in the geometry viewer, and need to be able to select a rectangular box
to zoom into.

	The problems that need to be resolved are:

	- Retrieving the coordinates of the selected point in respect to the
	  actual map, even when the point does not intersect the object, for
	  example when a box is taken near the coast.

	- Picking up button down events and dragging, and waiting for the
	  button up event.

	- Passing through of other events, such as clicking on a data tower
	  which is drawn on top of the map, to select vales, or other objects
	  present in the scene.

	I hopr this is clear enough, please let me know if you have any 
questions!!

Thanks in advance,

Paul

 Hello, 
   Pretty new to A.V.S and this group.

We want to do some animation where periodically we read in a new data set.

This can probably be done by "hand" but we have over 200 data sets to read in
for each animation. Is there any module written to do this? The avs animator
does not seem to support this. Is AVS shell script the answer? Is there a
module written to do this?

   Note: We read in two dimentional data with a scalar variable. The two
components stay the same, the scalar variable changes smoothly.

   I am missing something somewhere.

Does anyone have any experiences with the above transformation function?
In the developer's guide, it says that the function has two arguments as the following:

GEOMauto_transform_non_uniform_list(objs,n)
register GEOMobj  **obj;
register int n;

I understand that objs is the point to the object list. My confusion is in the
second argument n, What is n? the length of objs? or something else? The guide
does not say it explicitely.
Your help is appreciated!

Does anyone know whether it is possible to rotate fonts in the image and/or

Two simple questions on avs from a new user:

1. Saving a macro module.  How do I save a user-defined macro and use
it in later session?  The user's guide "Editing tools: macro modules"
page 8-13 purportedly explains how this is done.  But I never get a
prompt for file name after pressing Create Macro Module. 

2. Calling an avs module from other languages.  Is it possible to write
lisp code (or C if you will) that calls an avs module like isosurface
so that I can get hold of the points defining the surface for example?
I read a little bit of the avs developer's guide and is still not
clear how it can be done.

I am inquiring as to other's experiences licensing AVS. When we looked into the system last year, we we quoted $9500. for five users. The corporate machinery 
slowly turned and last we made new inquiries, we were quoted $32000. for five
users. It is more than a little disconcerting to see a product triple in price
within a year. What would happen next year if we tried to add more users?

Have others had this experience with AVS ? Does anyone have comments on whether
1) the price is fair and 2) whether animator is worth another $1800. As an
example, is AVS really worth more as software than SGI explorer with an Indy 
to run it? We were impressed with AVS last year, but I wonder if anyone can 
compare them from experience.
