I want to debug AVS-Modules. If I want to run the
module during debugging it fails with
Bad adress AVS_TMPFILE!
AVS_TMPFILE seems to be an environment-variable.
How do I have to set this, or are there other
things to do?

Thanks

The problem is that you are not waiting long enough after you start
running avs_dbx before you type 'run'.  You must wait for the message
"file instance waiting, fire when ready..." to appear before you
type run.  Give that a try and see if it works better for you.

(thanks to Jacque Caldwell for this answer - I didn't know, but she
says that she runs into this all the time because she gets impatient)

AVS CAMPUS PROGRAM 

Program Description

The AVS Campus Program is designed to allow wide use of AVS  and SunVision
in universities, colleges and schools at affordable prices. Under the
program, students and educators may purchase permanent AVS licenses for
under $1000. Special provision can be made for  teachers who wish to use
AVS for classroom tuition purposes and require a large number of licenses
for a course.

Advanced Visual Systems makes these very low-cost AVS licenses available to
any educational institution which joins the program and agrees to provide
central distribution, support and training services to their AVS user
community.  

Who can apply ? 

The AVS Campus Program is available to any non-profit educational
institution, faculty or department with a primary mission of education.. 
The program does not apply to organizations administered by a university
which do not have an educational mission. Licenses purchased under the
program may not be used for commercial purposes.

Individuals at institutions which do not enter this program can continue to
buy at the standard educational discount prices. 

Who can buy under the program? 

Anyone in the institution who is covered by the central support &
distribution services. In joining the program, an organization commits to
providing software distribution, support and training to their AVS users.
Anyone who is covered by these services can order licenses at the low
program prices.


 PRICING


Annual Fee:
up to 50 licenses	$12,500/yr 
up to 250 licenses	$25,000/yr

This annual fee covers program membership and support costs and must be
paid in advance for each year. It does not include any licenses, which must
be purchased separately at the prices listed below. AVS will bill the
institution on the anniversary date according to the number of installed
licenses. If the institution drops out of the program, the licenses remain
valid but users lose support coverage and must sign up individually for
support at standard rates.

Licenses:
AVS Fixed (up to 5 users)	  $750
AVS Floating		  	  $950
Animator Floating	 	  $500
Cray AVS			$2,500
SunVision			  $600

These are permanent licenses. Support is provided centrally under the terms
of the program. These are US prices. International pricing will differ.

(For comparison, standard list prices are:

AVS Fixed 			  $6500
AVS Floating		          $8000
Animator Floating	 	  $2600
Cray AVS			$30,000
SunVision			  $3600

These standard prices include only the first year's support.  There are
also standard educational discounts on these prices starting at 35% for
quantity 1)
 

CAMPUS PROGRAM OUTLINE

Program Contacts must be designated for business matters (contracts, P.O.s,
billing, etc) and technical matters (installation, training, license keys,
updates, support contact).

Distribution: AVS will send one update media kit and one set of
documentation. The institution agrees to duplicate and distribute all
software and documentation for all products and updates.

Documentation:	For each product, AVS provides one complete bound
documentation set and a master copy in Postscript and camera-ready form for
duplication. Additional bound sets may be purchased directly from AVS Inc.

Ordering: All orders must go through the Program Contacts and be on an
institutional purchase order. 

License Keying: AVS will issue license keys to the technical contact. 

Updates:	Program members can obtain all updates for products purchased
under the program from the technical program contact. Advanced Visual
Systems may introduce new products or extra-cost options which may or may
not be included under the program.

Support: 	The AVS technical contact must agree to act as single point of
contact to AVS for support. Two back-up contacts may be identified to cover
vacations and other absences. These technical contacts will have full email
and telephone access to AVS support staff. The campus end-users will have
no direct access and must go through the technical contacts.
	If a campus has multiple locations, each separate location participating
in the program must designate a local support person for end-users. This is to
ensure that beginning users have access to local expert assistance.

Training:	The institution must provide end-user training and 'getting
started' support. This training must include at least one 'Introduction to
AVS' class per semester.

What if I already have AVS ?

Your individual support agreement can be transitioned into support under
the Campus Program when your support agreement expires.  Customers who
purchased AVS from Digital Equipment or SunVision from Sun under these
vendors' academic programs can take advantage of the AVS Campus Program
when their institution joins. They become fully supported under the program
and can purchase new licenses at the low prices.

How can I apply ?
 
Designate a technical contact and a business contact to coordinate your
application, address the program requirements and act as the liaison to AVS
Inc. Then simply call your local sales representative or contact Kathy
McKone at 617-890-4300 or send an email message to kathym@avs.com.

	Just a reminder to send in your registrations for the 
upcoming AVS conference.  We are trying to make room for everyone
in the tutorials and workshops and coordinate larger lecture rooms
as needed.  The sooner we have your registration the easier it will
make it for us to make your conference a success.  Remember, there
are only four of us and lots of logistics for a conference this
size, so please help us out by registering as early as possible.  We
want this to be the best conference we can provide for our AVS user
group community.

	We also need volunteers from attendees and speakers to sit
on several panels.  Please contact David Bennett at avs93@ncsc.org
for more information on how you can help out.  This is where we need
the most help right now everyone!

	We would like to get at least 3 more exhibitors.  If anyone
has any suggestions, this will help us break even this first year
out in the big world.  Send suggestions to me.

	Videos and poster sessions are filled to the brim.  Thanks to
all who responded.

Hi,
	Is there a FAQ to this newsgroup? I am new to this newsgroup -- so
is there any site I can ftp the FAQ from.

Now the technical question:
	The data I need to visualize is uniform 2-D scalar. i.e, if I need to
to define a data structure in C, I would do it as:

 float array[100][100];

The data should be visualized as 3-D bar charts. 
For each x, y, the height of the bar represents the value of array[x][y].

So, it is basically a X-Y grid with bars at each grid intersection.


AVS does not seem to provide such a visualization mechanism. 
I would appreciate any help from the AVS experts out there.
If there is any site from where I can ftp a module which will do this work,
can you send me mail.

Thanks a bunch,

Sounds easy doesn't it? Just connect the image output port of the
geometry viewer to something that eats images...

The problem is that I have a geometry that has been edited repeatedly
in the geometry viewer (adding textures, changing lights etc) and
between the sessions it was saved as a "Scene", since saving it as a
network doesn't preserve things like textures. Therefore I had no
geometry viewer module in a network to use to output port of. And, to
my considerable surprise I couldn't fix this by simply dragging down a
new geometry viewer to the workspace (which creates a new camera) and
then click on the old camera. No amount of clicking produced anything
on the output port. As a desperate last resort I manually edited the
scene script and replaced the initial "geom_create_scene" with a
"geom_set_scene" instead. But since those two take different
parameters I was a bit sceptical about whether it would work. But
apart from various warning messages (I just closed my eyes) it did!
So I did get hold of the image that is now at the printers to become
the cover picture for our yearly progress report. Clearly a happy
ending.

Now the questions: is this the right way to solve this problem or is
there a better one? Or was it a bug that bit me? I use DEC AVS4 and
have not yet got AVS5 up, so it _might_ be a fixed bug without me
knowing it.

Re: ucd read-only shared memory UCD_RO_SHM


I hope that someone out there can confirm this as an AVS bug and/or
suggest a workaround.

I have a module which has one ucd input port and one ucd output port,
and its function is to scale the node or cell data in place.  That is,
it malloc's a new block of data, and calls
UCDstructure_set_{node,cell}_data().  I did this to avoid multiple
storage of the rest of the (extremely large) ucd - e.g. the xyz and
connectivity data.

Unfortunately, some change in AVS since I first wrote this module has
rendered it inoperable.  (Now we're on AVS5.)  The problem seems to be
that the shared memory segment holding the ucd information is in an
read-only state (inucd->alloc_case==UCD_RO_SHM), so a SEGV occurs if
UCDstructure_set_{node,cell}_data() is called.  This should not be the
case since the input port is created using the MODIFY_IN flag.

Any input would be appreciated.

Thanks,
Ray

Hi,

We're looking into running AVS on a Sun Sparcstation 10 system (which
has not yet been purchased).  We're looking for advice on what would be
an appropriate hardware configuration of a Sparcstation 10 for AVS.  We will
be doing 3D visualizations (isosurface, cross-sections, etc.) of multiple
3D fields, perhaps 3 or 4 fields at a time that are 50x50x20 points with
full coordinate information (i.e. irregular fields).  We will be doing
time-sequence animations with perhaps 40 time-steps of data.

We are mostly concerned with the graphics performance.  There are several 
graphics options available with the Sun; obviously the most expensive will 
be the fastest, but is it feasible to use one of the lower-level graphics
options?  Is it practical to use the software renderer on the Sparcstation
10?  Any practical experience or advice would be appreciated.

Also, are there any suggestions on how much memory will be needed on the
machine to accommodate our AVS needs?

Thanks,

-john

Hello!

We are looking for a possibility, to modify an ucd-structure at the screen.
Means, at example, you can klick a node and move it to another position
and automatically the coordinates in the ucd-structure will be changed.
Any help, how this can be realized, is welcome.

alpha based workstation to replace our aging and dying Stardent
GS1000.  One of the primary uses of the machine will be to run AVS.  I
would appreciate any replies from persons who are using one of the new

We use avs to view scientific data generated by 2-D and 3-D finite

G'Day

Is there any commercial or PD software for interfacing Matlab/IDL/AVS ?
I mean so that one can pass data structures as well as call the routines
from each package (eg call an AVS routine from Matlab or a Matlab routine
from IDL). I am sure we are not the only site which has all three packages,
given each has its strengths and weaknesses. Suppose I attempted to write 
such a beast. Would this breach any copyright or other regulations ?

Well, as sometimes happens, you ask a question and then figure out an answer.
I discovered what must be obvious to a seasoned AVS user, the module called
tracer.  It does ray traced volume visualizaiton on data of the form ARGB
(alpha red green blue).  I was able to flow one of the bricks into the
red channel and the other into the green using the combine scalar module.
You also have to include a brick of alpha values, since a tay in tracer
only stops when the sum of tha alpha along its path reaches 1.  I've
tried several different methods for generating an brick of alphas.

One person wrote to suggest I use isosurfaces.  I have done so with other
software, but I will try it with AVS as well.  The isosurfaces tend to
be pretty "lumpy".

Thanks for listening.

I know this question was asked a couple of months ago, but does anyone know of
any datasets of Earth images which are relatively public domain and are
configured or can be configured for viewing in AVS?

Thanks.  At this point, any reasonable resolution can be considered.

Major flaw in my opinion, AVS will only do linear contouring on UCD
data, which is not good enough for us, we need Quadratic isolines.
On the whole though, AVS on Alpha is impressive.

Mostly GIF format images of the earth at anonymous ftp ames.arc.nasa.gov cd pub/SPACE.
I don't know if there is a GIF reader for AVS these days.

              identical EXCEPT for the dimension in which the glue

G'Day

Is there any commercial or PD software for interfacing Matlab/IDL/AVS ?
I mean so that one can pass data structures as well as call the routines
from each package (eg call an AVS routine from Matlab or a Matlab routine
from IDL). I am sure we are not the only site which has all three packages,
given each has its strengths and weaknesses. Suppose I attempted to write
such a beast. Would this breach any copyright or other regulations ?

        best regard
                Ata <(|)>.

Here is some information from IDL>>>

Here is a little blurb about our new IDL-AVS interface that you could
send out via email to your user community. We are trying to gauge
user reaction and get some feedback about this before the AVS User
Group meeting in May. I really appreciate your help. Thanks.

*********************************************************
                        AVS-IDL Interface

Imagine, if you will, the perfect AVS module. What would it do? How
would you use it?

Maybe it would:

        * Evaluate complex mathematical expressions

        * Give you the capability of exploring your data interactively,
           in real-time.

        * Allow you to quickly prototype ideas--interactively--before
           you went to the trouble of coding them in C or Fortran.

        * Read and write *any* type of data format, including TIFF,
           GIF, Sun Rasterfiles, X Window Dump files, HDF, CDF, and
           net-CDF files.

        * Plot data as line plots, box plots, scatter plots, stacked 3D
           plots, polar plots, and histogram plots.

        * Display data as contour plots, surface plots, shaded surface plots,
           and images.

        * Allow you to display data as images or contours on a variety
           of map projections.

        * Allow you to create hardcopy output HPGL plotters, Laserjet
           printers, film recorders, and other types of hardcopy devices.

        * Allow you to build and prototype your own graphical user
            interfaces to AVS modules.

While the *perfect* AVS module probably doesn't exist, there is
something that we think comes close. IDL (Interactive Data Language)
from Research Systems, Inc. is now available as an AVS module. IDL
is an interactive command language for reducing, analyzing, and
visualizing scientific and technical data. It is an extremely powerful
array-oriented language, tailored specifically for scientific data. You
can use the high-level IDL language to create procedures, functions,
and entire applications (all of which run from within AVS), or you can
use IDL interactively to examine and display variables and pass results
to other AVS modules.

We are looking for experienced AVS users to test this new IDL
module and let us know what they think about it prior to the AVS User
Group Meeting in Orlando at the end of May. If you are interested in
helping us out, please contact:

extract the red channel from one volume, and the green channel from
the other volume.  that will give you the color information.  then
"OR" togehter the opacity channel from each volume.  

this will give you a volume in which you have something in the
red channel, something in the green channel and a combined opacity
in that channel.  in places where they overlap you will see yellow.

easy, eh?
