While going through the read_vol.c routine provided as an example
module by AVS, I noticed that the output port is defined as field 3D
scalar byte while the actual data is allocated as field 3D scalar byte
uniform.

Does anyone know why the declaration is not identical to the allocation?

Thanks,

o SUBMISSIONS OF DIGITAL ART NEEDED

Stream magazine, a new CD-ROM publication with a huge international 
distribution, is seeking submissions from artists who use the digital 
medium, in whole or in part, to create works of art. Stream focuses on 
the impact of technology on modern culture in a variety of areas. One of 
the most remarkable impacts of cheaper and more accessable technology can 
be seen in contemporary art. Reknowned artists like Laurie Anderson rely 
on advanced technology to make their statements. Print publications 
reflect the way computers are changing traditional design philosophies. 
Desktop publishing tools are	Wtting the power to create in the hands 
of the general populace, without requiring a huge investment in either 
time or money. However, a paint brush alone does not a Picasso make. 
Without a doubt, blossoming digital Picassos do exist though, and Stream 
intends to use its Gallery section to give them the exposure they 
deserve. 

Submissions may be of any style or process. The sole requirement is that 
the art reflects digital culture in some manner. Submissions may be sent 
to Stream via the Internet or by mail. Mail-in pieces may be on 44 Mb 
Syqyest, 128 MO, CD-ROM, Betacam SP, Umatic 3/4, or floppy disks. Maximum 
image size is 640x480, 16-bit color depth. Stream will publish as many 
images as possible within its space constraints.

Further information may be obtained by contacting Stream directly.

Hi AVSers!

I'm writing a module in AVS 5 that opens up a 'panel' no which the widgets
are placed. The panel is created using

 AVSadd_parameter_prop(param, "layout", "string_block",
 "panel Panel_Name -w panel -p ui -xy 271,0 -wh 747,524" );

in the description function. The Developers Guide says that you can use a
destruction function to close such windows. But... I can't get the panel
to vanish when the module is 'hammered'.

The destruction function issues the command:

    AVScommand("kernel", "delete_widget Panel_Name\n", &Outbuf, &Errbuf);

But the panel stays put. loading a network with the same CLI command in
causes the panel to disappear, and 'clear network' also gets rid of it, but
I want the panel to go away when I hammer the MODULE.

Does anyone know anything about this? Has anyone solved it? All help
gratefully received. Please email as I don't read news that regularly.

I am looking for a module equivalent to read_Flow3D which handles
data from FLUENT (a commercial cfd code).That is a module which reads 
a FLUENT solution file and stores the cfd data as a ucd data set 
(or in another data format which enables me to post-process the data in AVS).

Could anybody help me out with this one?

is really describing a rectilinear field, not a uniform one.  You
have a resolution specified in the third direction.  There are 
(unfortunately) a bunch of modules which require a uniform field,
but if you define your data a rectilinear, you should be able 
to use most modules and have the geometry in the third direction
look right.

I'm trying to make an animation of an isosurace which changes
shape over time. So far my attempts have been disrupted by having
the surface change position spontaneously (ie, between frames the
apparent viewpoint changes).

This phenonmenon is described in the User's Guide on pg 5-8:
  Some mapper modules elect to mormalize an object within the view 
  volume themselves. By making an additional call to the libgeom 
  library, they instruct the Geometry Viewer to "rescale and translate"
  the Top level object's coordinate system so that the object will fit 
  within the display viewport. ... On rare occasions, this advantage can
  be a disadvantage if you are, for example, creating an animation. The
  scene in the display window may jump each time a new geometry enters
  as the Top level coordinates are normalized.

The manual offers no suggestions on how to keep this from happening. 
Since I can't believe that animation is as "rare" as the manual passage
suggests, someone must have found a work-around. Anybody want to share
their method for making objects stay put?

I am posting this for someone without direct news access:

Hi there

We have been trying to plot flow vectors and streamlines of a 2d
vector field in 2d space (i.e., (vx(x,y), vy(x,y)), say). 
Unfortunately, AVS does not provide a supported module to do
this.  Does anyone know of one?

Instead, there are the HEDGEHOG and STREAMLINE modules which only
accept a 3d vector field in 3d space (i.e., (vx(x,y,z),
vy(x,y,z), vz(x,y,z)).  In order to use these modules we have had
play a couple of tricks:  (1)  Since the spatial field is
actually part of a time series, we have used the time axis as the
z axis.  This gives a 2d vector in 3d space (vx(x,y,t),
vy(x,y,t)).  (2)  We have made a null array for the vz component
to get the desired 3d vector in 3d space.  This should then allow
one to get a hedgehog or streamline plot out in geometry viewer. 
One chooses the PLANE option for sampling to get a 2d cut of the
vectors/streamlines at a given time.  However, one then hits more
problems:

1.  In general, the time axis has very different dimensions to
the spatial axes.  This results in a thin slab geometry.  This
makes it very difficult to select with the mouse the time step
at which the plane cut is being made.  We have written an AVS
module to scale up the rectilinear coordinates of the time axis
to the same magnitude as the spatial axes.  This gives a more
cubic geometry.  However, when one moves with the mouse the cut
plane with the hedgehog vectors in it the vectors either remain
unchanged despite the cut plane having moved or the hedgehog
vectors disappear altogether, never to be seen again.

2.  Instead, if one tries to precisely place the cut plane using
the transform object options similar effects are encountered.

Does anyone understand where we're going wrong?  Does anyone know
of a way to precisely position the hedgehog/streamline cut plane
in physical or grid cell coordinates that also updates the
streamlines or hedgehog vectors in the geometry viewer?

Cheers

I have just such a filter program. (And as a bonus, a module to visualize
time-dependent FLUENT data). My company is distributor of FLUENT in
Japan and it sells the stuff as part of AVS/FLUENT program. That is
why I cannot make it as pds though I want to.

For people outside Japan, you can get it free if you drop me a line,
provided you do not help anybody re-importing it in Japan.

To follow up on Mike's message, the exact locations for hog and streamline 
can be specified by the sampler input port of these modules.  The sampler
module is not very useful though.  I have used output from slicers and my own
filter module.  They work well.  As regards 2D hog and streamline, I did a
similar hack to zero out the 3rd component.  Somehow that didn't work too well.  
So I wrote my hog2d and am now working on a streamline that works for both 2D
and 3D.   If you like to try out the hog2d, email me.  

On the streamline module, can someone explain the meaning of the length
and time parameter?  The streamline is an instantaneous notion.  I don't
understand the role of time here.  Does time mean arc length here?  And length
mean number of steps?  

Also, regarding the integration method, is Euler = forward Euler, and Runge
Kutta = midpoint method = RK2?  What is the interpolation routine?  trilinear
or something better?

Anyway, if someone has the source for streamline module, I'd like to get a copy. 
I want to make a more accurate integrator with step size control.

Hi again,

   Can someone give me a reasonable explanation of the transformation
matrix sent to GEOMedit_set_matrix(*list,"camera1",matrix);?

I was under the impression it was something like this:

       --             --
       | t1  t2  t3  0 |  /* Third vector = U x V */
       | u1  u2  u3  0 |  /* Up vector            */
       | v1  v2  v3  0 |  /* View Vector          */
       | f1  f2  f3  1 |  /* "From"               */
       --             --

But there's definitely something different when you apply this to a camera
by using GEOMedit_set_matrix. Obviously a piece of the transformation chain
is escaping me.

I've worked around this by doing my own extraction of at, from, and up from
the matrix and using GEOMedit_camera_orient, but I'd really like to do it
the way AVS does it just for my own understanding.

I've tried some trial-and-error of inversing/transposing before and after
sticking "from" into the matrix, but I always seem to be looking at the
origin.

Thanks an uncorrupted heap,
Scott

If anyone has noticed there is a hog_2D module sitting over at
ftp://avs.ncsc.org written by some unknown author.  Unfortunatly,
this module sucks eggs.  Something better would certainly be 
of benefit to all of us trying to do 2-D vector stuff.  

BTW: has anyone made a 2-D gradient module like 'vector grad'? I'm

Please correct me if I am wrong!!

thanks,

Hello!

Polygons and pollylines were generated by AVS, using Arc/Info Moss data file.
How to colorize these polygons and polylines?

Your suggestions are highly appreciated. 

Thanks,

Vijay

How do I get help from IAC! I e-mail them and all I get back is automail.
I want them to check out a module they have known as glue...it doesnt work!

Can anyone suggest a module that would take a number of 2-d files and stack them into a 3-d volume!

Hi Sandy,

The automail account(s) you mention are probably avsemail@ncsc.org, and/or
avsorder@ncsc.org.   I don't see any messages from you to our regular
"people" email address (listed below).

Any message sent to avsemail@ncsc.org will automatically send you back a
copy of the latest catalog of modules, the IAC's AVS_README file, and info
on joining the International AVS UG.

Once you have the catalog of modules returned automatically from 
avsemail@ncsc.org, you can send messages of the form
#1234
to avsorder@ncsc.org, and you will automatically receive (via email)
all of the files associated with module #1234.  This is useful for
folks without ftp access, who do have email access.

If you want to check with PEOPLE at the IAC (as opposed to computers)
please send your message to avs@ncsc.org.  Sometimes it may take us
a few days to respond, but often we'll get back to you that day.

Regarding your question on the glue module - it can be a bit tricky to
use at first, but actually that is a favorite module of mine and I have
used it successfully a number of times.  What platform are you running
on, and how specifically is it not working?

Take care,

-Steve

PS:  Would you be interested in sharing your AVS work with the
scientific visualization community worldwide via a short article 
and / or slides in an upcoming issue of AVS Network News?  This 
is the IAC's quarterly magazine made up of user contributed 
articles.   

PPS: The IAC is supported in large part by the dues it
receives from memberships at $36.00 per year.  This
includes quarterly publications, $50.00 discounts at

How you visualize high-D data depends a lot on the nature of your data. If,
for instance, you have 3-space 3-vector data (i.e. position + velocity), you
could map an arrow to the velocity components, and the magnitude of the 
velocity to the length of the arrow. The root of the arrow is determined by
the position. Beyond that level, if you wish to have a higher-dimensional view,
or if your data isn't that straightforward, you'll probably need to use some 
sort of glyph to encode the extra dimensionality.

Alternatively, you could try a projection pursuit method in which certain
dimensions are held constant and only 2 or 3 are varied dynamically on the 
display.

Good luck,
Loren

 ___________________________________________________________________ 

1.	 What is the International AVS Center ?

        The International AVS Center serves as a catalyst
for expanding the AVS user base and for increasing AVS
functionality by fostering discipline-specific module
development and new AVS uses.  Located at the North Carolina
Supercomputing Center, the worldwide clearinghouse collects,
ports, and distributes user-contributed, public-domain
modules and acts as liason between users and vendors.
The International AVS Center also publishes a quarterly
magazine called AVS Network News and a yearly module
catalog.  It also hosts the yearly International AVS
User Group conference and coordinates User Group activities.

        The AVS Consortium is made up of eight AVS vendors
who are funding and providing direction for the International
AVS Center.  The eight vendors are Advanced Visual Systems Inc.,
CONVEX Computer Corporation, Digital Equipment Corporation,
IBM, Hewlett Packard Company, Kubota Pacific, Sun Microsystems,
and Wavetracer, Inc.
 ___________________________________________________________________ 

2.	 Where is the International AVS Center ?

        The International AVS Center is located at the
North Carolina Supercomputing Center.  The anonymous ftp
site for the center is located on the internet at avs.ncsc.org
with an IP address of 128.109.178.23 .  The main email alias
for the center is avs@ncsc.org .
 ___________________________________________________________________ 

3.	 What is AVS ?

        Using anonymous ftp to avs.ncsc.org, you can then
get the file What_is_AVS.  Take a look at this file
for a good summary of what AVS does.
 ___________________________________________________________________ 

4.	 Where can I get more information on AVS ?

        If this file and other files available via anonymous
ftp to avs.ncsc.org do not answer your questions, you can
send mail to avs@ncsc.org.  The International AVS Center
will do its best to help you out.  You also may want to
monitor and/or post articles to the Internet newsgroup
comp.graphics.avs, which has an ongoing dialog between
various AVS users.  Or you can contact AVS Inc. directly at:

ULTRIX V4.2A includes a PEX V5.0 server.  For compatiblitiy with
that server, DEC AVS V3.0A has been released.  Note that
PEX V5.0 provides (two pass) transparency.  Also note that
the ULTRIX V4.2A distribution does include a PEX compatibility
kit which is essentially a PEX V4.0 server.  There is no support
for runing both PEX V4.0 and PEX V5.0 servers concurrently.  Only
one such server can be run at any one time.

Hewlett-Packard - Available now - HP 9000 series 700,
CRX graphics (call for information on other graphic configurations),
OS release 8.01 or later ( 'uname -r' to get OS level), Phigs runtime
will be required for systems using H/W rendering, 16 MB memory

command 'lslpp -h bos.obj' which should show release
03.01.0006.0008 as active, use command 'lsdev -C -c adapter' to see
graphics configuration, 16 MB memory minimum, 32 MB
recommended, installation uses about 40 MB disk, hardware
rendering is only on 24-bit Z buffered systems, specify SW
renderer on all systems without 24-bit Z buffering, AIX 3.1.5
X server is limited to 8-bit pseudocolor visuals, images are then dithered.

SUN - Available now - Sun SPARC workstations 1, 1+, 2 supporting
the sun4/sun4c applications architecture, 8-bit frame buffers (GX,
CG3, etc), GS and GT graphics after OpenWindows version 3 is

render also available

Wavetracer - to provide users with logical and uniform access
to Wavetracer's three-dimensional and massively parallel Data
Transport Computer (DTC) and advanced software tools, AVS modules
are currently being ported to make use of the DTC.  The DTC
is a three dimensional, massively parallel computer.  It has
a 3D computing architecture, high data capacity and bandwidth,
high I/O bandwidth, ultra finegrained parallellism and low cost
of ownership.  It easily connects to a host UNIX workstation
via an industry-standard SCSI interface.  The processing
resources of the DTC are integrated into the host's software
and network environment by multiC, a powerful data-parallel
extension of ANSI C.
 ___________________________________________________________________ 

6.	 How do I download modules from the International AVS Center,
	 or submit modules, or get a list of the currently available
	 modules ?

        There is an AVS_README file which should answer
these and many other questions for you.  To obtain a
copy of this file, there are two methods currently
available and a third method under development.  Mail
sent to avsemail@ncsc.org will automatically retrieve
a response which includes the AVS_README file and
also a current module catalog.  Or you can ftp to
avs.ncsc.org, login with anonymous as your userid and
your own userid as the password, and get the AVS_README
file and the AVS_CATALOG file from there.  For those users
without ftp capability, there is a tape ordering system
being developed at the International AVS Center.
 ___________________________________________________________________ 

7.	 When I try to run AVS on a remote machine and display the output
	 on an X server, I get a message saying Client unauthorized to
	 connect to server. How do I fix this ?

        The xhost command will let your server know its
OK for your remote machine to display there.  In the
file read in when you boot up X (for example, on a Titan
.xsession, on a Sun .xinitrc), add the line:

        xhost <Client1 machine name> <Client2 machine name> ...
 ___________________________________________________________________ 

8.	 Is there sample AVS data available ?

        Using anonymous ftp to avs.ncsc.org, you can then
cd to AVS_SAMP_DATA.  This directory is for sample data that
has been donated without any modules.  No tests have been made
on this data, so use it at your own risk.  This is simply to
allow you to get your hands on a variety of different data types
for experimentation purposes.
 ___________________________________________________________________ 

9.	 When I try to ftp to avs.ncsc.org, I get terminated before I get
	 connected. What am I doing wrong ?

        Possibly your host machine isn't a registered
internet site.  In such a case, the IP address can't be
mapped by our machine into a valid hostname.  Speak to the
person in charge of your network about making sure it is
correctly registered.
 ___________________________________________________________________ 

10.	 What is the procedure to add a question to this FAQ file ?

        Please submit your suggestion for this FAQ file via
email to avs@ncsc.org.  Your question and answer will quite possibly
show up in this file shortly thereafter.
 ___________________________________________________________________ 

11.	 Why should I submit a module to the International AVS Center ?

        Donating a module to the International AVS Center benefits
the entire AVS user community by facilitating further use of AVS to
visualize complex scientific phenomena.  Any module that is not
donated may be rewritten elsewhere - wasting someone's
valuble time - hindering further development of other module
capabilities for everyone's benefit.

13.	 What is WAIS ?

There is now a WAIS (Wide Area Information Servers) server running
at the International AVS Center.  WAIS allows a user to ask
a question to a server, which provides a ranked list of documents
that may help answer that question.  The user can then peruse
through the documents that seem useful.  

All of the .txt files for AVS modules freely available on the 
International AVS Center's anonymous ftp site have been indexed, 
as well as informational files such as AVS_README and FAQ.  
WAIS should prove more and more useful as the AVS module repository
becomes larger.  It provides a convienient interface to large amounts
of data.

There is also an archive of all postings to comp.graphics.avs 
beginning with May 1992.

For a more thorough discussion of WAIS and how you can use it
to peruse the files at the International AVS Center, please check 
the file WHAT_IS_WAIS on avs.ncsc.org.
 ___________________________________________________________________

Summary: Who makes AVS?  Is there a FAQ?

EASY question:

	Who makes AVS?

I searched the newsgroup for a FAQ  (is there one??)  or
reference to the company's name, but nothing.  If you are
a user/lover of AVS, could you tell me how it contrasts
with IDL, which is what I am considering buying (unless
AVS is better/cheaper...).  IDL runs on a bunch of machines,
which is attractive, and is publicly available to ftp a
demo version.

Avs makes Avs...helps ya hugh?   Well actually Avs was a software package put out by a joint company known as Stardent (made up of Stellar and Ardent) Now Stardent is out of business and the software people formed AVS International
The e-mail address is avs.ncsc.org
Ftp site is avs.ncsc.org
It costs about 6 thousand...Everyone...is that right?

The hardware people are still in business, they're Kubota Pacific Computer,
and they make the Kenai/Denali graphics subsystem for DEC Alpha workstations.
It's not a whole workstation, but it's one heck of a powerful graphics machine.
It fills a price and performance gap between SGI's Extreme graphics and SGI's 
Reality Engine, with scalable price and performance based on how you configure
it.

Not affiliated, just thought it should be mentioned.

Except that KPC has, as of last week, has withdrawn from the UNIX 
market in favor of the PC market, and will stop selling Denali.  
 
I recieved a letter that began:

"Dear Mr. Signell, 
  We would like to share with you a change in our business direction..."

Just 90 days after I recieved *my* Denali!!

Hi,

   I beg someone-who-is-familiar-with-UCD's help. I'm embrassed with the mid-
edge-nodes information.
   As you know, one of sample data of UCD `tet.me.inp' contains that. In it, a
tetrahedron cell with every mid-edge-node is described. Its node-list line is:

1 1 tet 3  4  2  1  0  0  0  0  0  10.

Since No.0 node doesn't exist, it may mean that only the last mid-edge-node is
valid (isn't it?). But, once this is read by the `read ucd' module, the node
list appears as minused by 1 form:

2 3 1 0 0 0 0 0 0 9.

   I think this maybe because of C-like-indexing (begins with 0), but, in this
form, I cannot distinguish `0-th node' from `non-existent node'. Does anyone
know how?

Actually, they changed their name a couple of months ago to "Kubota
Graphics Corporation."

Not to mention they laid off the majority of their work force...

Aloha,

I downloaded read_tiff_image from AVS, but libraries do not seem updated to
Solaris 2 operating systems for Sun Sparcstations.  Does anybody know if and
when this will be upgraded (mainly talking to the author here).  If not, is it
possible to free all source code so us users can compile everything from
scratch?

Thanks anyway.

Koen Janssens.

Russ,
	AVS the product (Application Visualization System) is from 
AVS Inc. the company (Advanced Visual System, Inc).  They're located
at 300 Fifth Ave, Waltham MA, 02154 (617) 890-4300, email to avs.com.  

This is not to be confused with the International AVS Center (IAC) located
at the North Carolina SuperComputing Center (NCSC), a division of
MCNC.  This is where the free goodies from the AVS user community is kept.
You can reach the IAC via ftp at avs.ncsc.org (128.109.178.23)

Hello!
I've got the READ_ANY_IMAGE and WRITE_ANY_IMAGE module from avs.ncsc.org.
Most of the formats work quite well. I only get trouble with images written
as TIFF. I've tried to import those files in COREL DRAW 4.0 or to read them
with a DOS TIFF-Viewer. But I always got a format error. AVS is able to
read the files with the READ_ANY_IMAGE module.
Does AVS use another TIFF format than COREL DRAW, or is there a bug in the
AVS TIFF format?

	Hi

I try to build a module who take 1-7 chanel and build a image.
But my module have 7 input of exactly the same type.

The fuction "AVSinput_changed" seems to have a parameter to choice which
connections are looking for. I think it's may be possible to define a multi
input port of the same type. But I don't have find such information on the
AVS documentation.

May somebody help me for this small problem?
(Small because my module works well, but it may be much pretty to not have
7 time the same input port, when it doesn't matter for me to have a order
for the input port)

Please email directly:

Hi, sorry that I cannot give you any information.
I also wish to know how to accomplish multi-input-port, just for curiosity. 
(Internal modules, image viewer & geometry viewer, actually DO it!)

                   ******  Announcement  ********

          AVS and Uniras Users Conferences 6-8 September 1994

               Uniras UK User Group and UK AVS User Group

                    University of Kent at Canterbury

The UK's AVS and Uniras User Groups are holding their
conferences in parallel at the University of Kent at
Canterbury. This comes almost one year after the new company
AVS/UNIRAS was formed and provides an opportunity for AVS and
Uniras novices and experts, suppliers and customers to meet
in pleasant surroundings and share their knowledge of the
software. Key AVS and Uniras experts from AVS/Uniras are
coming from their bases in USA, UK and Denmark to give us the
latest information on releases of the software. Leading users
of AVS and Uniras, commercial and academic, will offer their
experience on these products.
 
To give delegates more time for travelling to and from
Canterbury, the programme itself will begin with an evening
meal on Tuesday 6th September. Delegates may, of course,
arrive earlier on Tuesday to explore Canterbury and the
Cathedral or to attend the workshops described below. The main
conference sessions are planned for Wednesday 7th September
and tutorials will be held on Thursday 8th September. The
programme will close at about 14:30 on Thursday.
 
Here is a summary of the programme:
 
 * Uniras and AVS parallel sessions (Wednesday morning). No
   restrictions on which sessions you may attend. There will
   be further AVS user sessions on Thursday morning.
 * Combined session of interest to AVS and Uniras users
   (Wednesday afternoon).
 * AGMs of both user groups (Wednesday).
 * Conference dinner at the beautiful Chilham Castle
   (Wednesday evening). 
 * Tutorials (Thursday morning) - Graphics via World Wide Web,
   PostScript Graphics, AVS module writing.
 
Cross-attendance is allowed, even encouraged. However if you
are interested in only one of the product ranges, you will
find a complete set of sessions of interest to you.
 
The standard charge (155 pounds) includes accommodation on campus
for Tuesday and Wednesday nights; attendance at all sessions
on Wednesday and Thursday and all meals and refreshments from
Tuesday dinner to Thursday lunch, including the conference
dinner at Chilham Castle.
 
With this full programme, fine conference dinner, and the
first opportunity to find out more about AVS and Uniras at one
venue, we expect this year's conference to be very popular.
So to avoid disappointment fill in your booking form and
return it as soon as possible.
 
A programme and booking form are enclosed. Feel free to make
copies to distribute to colleagues who might be interested in
attending.

Preceding the conferences, but not part of them, hands on
Unigraph and AVS/Express optional workshops will be held on
Tuesday afternoon (including lunch). Space and access to
workstations is limited, making registration for a workshop
essential - get your booking form in early! 
  
       -  The workshop "UNIGRAPH beyond the Workbook" is free
          to Uniras UK User Group members attending the conference.
  
       -  For the AVS/Express workshop, an additional charge
          will be made.

Unfortunately I think this is not possible. I also tried it :-(

In the AVS 5 Update Manual, it says on page 11-1 that multiple connections
to a single iput port are only available to the buildin modules and
not to user modules, so the the connection number in the "AVSiput_changed"
function should always be 0. Too bad.

Hi,
   I am having a problem sending upstream_geom info from ONE geometry viewer module
to TWO different upstream modules. Only one of them, at any one time, thinks their
input port has changed. They both work individually, but not when both are hooked
up to the geom viewer. Shouldn't they be able to share the info?

Thanks,
Loren

Hi Folks,

Just an advance warning - the IAC's ftp site (avs.ncsc.org)
will very likely be going temporarily off-line sometime
on Friday, for up to several hours.  One of this disks
is going to be replaced, due to a bunch of failures
it has had.

Take care all,

Hi there,
As I think I've got similar experience, I write about it.

I once tried to trigger two input ports simultaneously (I expected parallel execution.) using downpstream data flow, but failed.
They are triggered individually and occasionally worked in parrallel.
These two modules are both remote modules and located at defferent machines each other.
It seemed that the trigger depened upon the connection order and the execution order of modules was not controllable.
I consulted the Kubota Computer Japan office (They are resposible to AVS in Japan.) and they said controlling these was impossible.

I think that the inter-process communication procedure in AVS gives us an exact answer.
Do you have any information of it?

**************************************************
Welcome & Hotel Info.

Welcome to IEEE Visualization 94: This fifth annual IEEE 
Visualization conference promises to be our strongest 
technical program yet.  As with previous VIS conferences, our 
focus is devoted to visualization and its applications.  We will 
offer you tutorials on Sunday, Monday and Tuesday. In addition, 
we offer you a Symposium on Volume Visuaization.  The 
symposium is a two-day program scheduled for Monday and 
Tuesday.  Wednesday morning begins with Keynote Address and 
Panel, followed by our three track concurrent sessions and 
demonstrations.  You will have your choice of papers, panels 
and case studies on a wide variety of visualization topics.  
Demonstrations of visualization products, tools, and 
applications begin mid-day Wednesday and continue through 
Thursday afternoon.  Birds of a Feather sessions are scheduled 
for late afternoon on Wednesday and Thursday evening.  The 
conference concludes with the Capstone Address on Friday 
afternoon.  Our Advance Announcement describes the general 
program content and gives you registration and hotel 
information as well.  In another month, we will be sending out 
our Advance Program which will describe the complete 
schedule with paper, symposium, panel and case study titles, 
speakers, and their affiliations.

We encourage you to join us in Washington, D.C. the week of 
October 17 - 21, 1994 for IEEE Visualization '94.  The 
conference is an important forum in the area of data 
visualization and a unique opportunity for interactions with 
researchers, developers, and colleagues.

This BoF will invoke an in depth discussion on the 
integration of multi-platform data analysis software and 
an advanced database system with virtual environment 
generation software.  Ideally, the resulting combination 
would enable the various programs to respond 
to calls from each other allowing automation of data storage, 
analysis and display. A primary discipline focus prompting this 
juncture includes visualization of waste site characterizations 
and remediation using immersive environments.  We would like 
to promote a
discussion on this topic that will address such issues as 
strategy, potential problems and solutions, 
hardware/software, and implementation.   Activities 
proposed include an open discussion and a short video 
presentation of work to date.

Education and Visualization are often focused on a narrow 
aspect, namely the use of visual techniques for education.  
Within the education community, the interest in visual and 
interactive techniques for teaching constantly increases.  
The gain for the students is rooted in increased motivation, 
improved intuition for complex problems, and better 
communication and collaboration skills.  While the use of 
visualization for teaching is important, visualization 
utilizes new methods and tools that also need to be 
taught in order to be used correctly.  The correct use of 
visualization is not inherent in a person, but needs to be trained 
similarly to the use of statistics or the design of user 
interfaces.  This BoF will therefore focus on  teaching 
visualization at the university level. Education in visualization 
will benefit professionals in areas such as the sciences, 
technology, business and education.


		TUESDAY EVENING SPECIAL SESSION
Tuesday 7:00pm
How to Lie and Confuse with Visualization (VizLies '94)

People have lied with statistics and maps for years.  Now it's 
time to look again into lying and confusing in the field of 
visualization. Your once-a-year big chance to do just that, in the 
open, will be in this special session on Tuesday, October 18, 1994 
at 7:00 pm.  You are invited to bring with you visualization lies 
and confusing articles, yours or others, on 35 mm slides or video.  
During this evening, it will be allowed to lie but not to borrow 
credit, so please do not forget to mention the producers' names.  
After the informal presentations and truthful debates, the 
audience will choose the biggest (visualization) lie for 1994.  
When the evening is over, lying will be outlawed again (for 
another year).  Then, we will be all able to benefit from this 
teaching of what it takes to produce realistic and faithful 
visualizations.

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

How to present color images to color deficient viewers? How to 
deal with distributed environments where color resolutions, 
capabilities, and specifications differ from one location to 
another. The objective of this tutorial is to answer these 
questions, but even more so, provide students with the tools to 
answer these questions themselves. The tutorial will introduce 
basic color theory and will continue to address the specific 
needs of those who put images on computer screens.

the software engineering process to include all members of the 
work group; the visualization end-user, the visual language 
programmer, the toolbox programmer, and the infrastructure 
programmer. The tutorial will concentrate more on issues 
related to the productive creation of visualization software by 
the visual language and toolbox programmer.

TUTORIAL 8
Monday 1:30-5:30
Visualizing Multi-Dimensional Geometry & Applications to 
Multi-Variate Problems
Alfred Inselberg, IBM T.J. Watson Research Center
K. Esbensen, SINTEF
A. Chatterjee, University of Southern California
Level:       Beginning/Intermediate

The desire to augment our 3-dimensional perception and the 
need to understand multi-variate problems has attracted 
considerable attention and motivated several visualization 
methodologies. Starting with a review of the field, the 
connection between multi-variate problems and multi-
dimensional geometry will be established. Understanding the 
underlying geometry of a multi-variate problem provides 
important insights into what is possible and what is not. 
With this motivation, the visualization of multi-dimensional 
Geometry and multi-variate relations using Parallel 
Coordinates will be rigorously developed. Relations among N 
real variables are mapped uniquely into subsets of 2-space 
having geometrical properties enabling the visualization of 
the corresponding N-dimensional hypersurfaces. After the 
basic representation results, associated algorithms for 
constructions, intersections, transformations, containment 
queries, proximity and others will be given. The theoretical 
material will then be applied to a variety of application 
areas.

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 
downtownWashington, 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.

Two recent IAC modules, "Mouse Trap" and
"Mouse_Trap_IV" catch mouse input events just in front
of the Geometry and Image Viewer, respectively.
They are designed for special purpose interaction,
just as you describe.

They do not get the private X resource from LUI as you
suggest, they reparent a new input-only X-window as a child
of the geometry viewer, always the same size and mapped in
front of the viewer.

	If it any use I guess you could stop the flow executive with a
CLI and then send the output and then start the flow executive
again. I think this should work.

	I guess you would need a co-routine for this to work.

Best of luck,

You should be able to get the modules to run in parallel if you start avs
with the -parallel option AND the modules are in separate processes.  If they
are on the same machine, then parallel execution will be simulated using UNIX
multitasking, if they are on separate machines then true parallel execution
should occur.

As far as controlling the order in which modules get fired, its a bit 
difficult to predict.  Connection order probably does play a part, and 
ultimately, the height of the module icon in the network editor.  We have had
some problems here predicting execution order when using upstream data.

If anyone does have more info about this we'd find it useful

Well, close but not quite...

Advanced Visual Systems Inc. (AVS Inc.) makes and sells AVS (the
Application Visualization System).  

The International AVS Center (IAC) located in the North Carolina 
Supercomputing Center manages the anonymous ftp site of 
user-contributed modules as well as the International AVS Users 
Groups.  

The price for a non-educational node-locked license starts at 
$6500, but volume and academic discounts can be applied.

Here is some contact information:

I hope this helps - I know that it is confusing having both AVS Inc.

some of the differences up.  Please feel free to contact me for other

We are interested in producing true 3D hardcopy of some seismic
derived geometric structures. I talked to the folks at Laserform Inc
of Auburn Hills Mich, and they say to get it into an STL format. A lot
of the CAD design packages can do STL now (IDEAS, UniGraphics, CAD
Key, etc) I am wondering if there is some way to migrate AVS geometry
data via AVS + (?) to produce an STL format file. I do know that there
are geometrical (hehe) considerations for producing stereo-lithography
products, some of which we can deal with up front in AVS -- others
Laserform deals with. For instance, we have disconnected blobs, and
Laserform has a way of carrying the blobs on a fabric-like mesh.

Has anybody done this before in AVS?

AVS 5.01 was compiled with the UNBUNDLED (spoken with angst, I must be
part of generation X) ANSI C compiler. 

We're using gcc to get ANSI compatibility and not having any problems,
mainly because we're still at 4.0.3, and not planning on upgrading any
further.

To get around it, put this in somewhere:

#include <stdio.h>

void __ansi_fflush (fp)
FILE *fp;
{
	fflush(fp);
}

Does anyone know if there is a way, in AVS, for the user to choose
multiple entries from a list, where the number of entries is dynamic
and can be large (tens to hundreds)?

I'm looking for something like the following widget design: Present a
text window scrollable in the vertical.  Get, from the associated
module, a text block of N lines and a reference to an array of N
marks, one per line, indicating which lines are selected.  Allow the
user to select zero or more lines with selected lines highlighted.
Include a "done" button indicating that the selection is complete and
the module may process it.  The mark array would be modified to
reflect the selections.

Thanks,

OK, here's a question related creating GEOM objects.  Let me try
to make some sense here.

I'm creating multiple objects using a module modified from the pick_cube
example routine.  My problem is that I want to create a series of objects
that have a sort of heirarchy.  Such that in the geometry viewer they
will appear as children of one common parent, and can be selected as a 
whole.  Is this possible?  

If anyone has examples of a modified pick_cube module I would certainly 
like to see the source code.

  I am using Chemstry Viewer to write avs applications. Recently some problems
are encountered. The problems are all around the user data.
  
   First, I could not allocate space for the user data by calling 
MSImolecule_alloc_user_data(mol) while "mol" has already got the momery;

   Second, I could not find where the return values ( MSI_MOL_OK, etc) are
defined.  It should be in "~/MSI/include/mol_udat.h" according to the
Programmer's Guide (version 1.0);
  
   Third, I actually found that the user data structures defined in "mol_udat.h"
and "atom_udat.h" are different from the ones in the Guide. New members are 
added. Is there any new version of Chemistry Viewer published?
  
   If anybody knows about these, please give me a help. Thanks.

It seems to me that the generate_colormap module restricts the user
to the range of hues that can be specified when customizing a colormap.
For instance, there isn't any way ( that I can see) to set up a colormap
that starts with blue at the low end of the  scale and gradually changes
to red at the high end of the scale without passing through the default
hue scale (blue-->green-->yellow-->orange-->red).  In other words, I can't
find a way to linearly interpolate between two colors.  Has anyone done this?


Thanks in advance,

Now there's a good idea! Can you let me know when you find out. Even better, 
post your findings here so we can all see!

I need to do a similar thing. I can generate dynamic radio buttons, but 
they're no good if you want the user to be able to select more than one
option.

Pete,
Check-out the "geom_parent" module under the data output directory in the

Tim,
Try this:  Press "edit" on the control panel of "generate colormap", and
change the "Max" parameter to 360 (its default is 240).  This controls the
range _in degrees_ over which the hue can vary.  Then set the "From value"
to 1.0 (for red) and the "To value" to .6666 (for blue); these numbers are
_not_ in degrees, by the way, but are instead the fraction of the way
arround the hue circle.  Then press "do interpolation".  Voila! - no greens
or yellows!  I assume other transitions could be made in a like manner.  I
find that the Edit Property widget under the geom viewer is invaluable for
experimenting with colors.

I've been working with avs geometry viewer feeding in 3-D fields
through isosurface filters, also using arbitrary slicer and volume
bounds. I sometimes encounter the following problem: I get an initial
view of the field but when I try to rotate the "box" it just
disappears and I have to click on Normalize button on Geometry Viewer
Panel to get back the view of the rotated field. When everything works
fine I can see the box contour as I rotate it with the mouse, but
when I get this problem it just disappears as I try to rotate it and
then the object vanishes too.
Has anyone encountered this problem? Could that be a bug in the
program or my data might be corrupted?

I'm interested in the opinions of users of explorer,
AVS version 5 and AVS/Express in regard to these issues;

       1) Why you use/choose Explorer / AVS5 / AVSExpress
       
       2) Your experience with limitations (eg, "I thought that
          getting control of INPUT ports of Explorer modules would be
          a very basic function.  It's not."
       
       3) If you have used more than one package, do you have a
preference?
       
       4) What type of system do you prefer to operate on.  Does
          Explorer / AVS5 / AVSexpress support that platform.
          
       5) What are your reps telling you about the future of the product.
       
       6) ... any other comments that would be useful in making an

If the center of rotation of the object displayed by the geometry viewer
is far outside the object's extents, a small mouse movement can let
it rotate out of the viewport. If you select the object and then 
click on "center" in the geometry viewer's control panel, the
center of rotation should be recalculated to be in the center of the
bounding box. Hope this helps.

Hello All,

who is using AVS for visualization of "stuff" underground.
I'm looking for anyone who is visualizing  3-D contaminant
plumes, velocity fields, head distributions, etc in 
geologic structures.  I guess anyone doing  
groundwater visualization, environmental pollutants transport could help.

I'm seeking ideas on how to represent this type of data with the most 
information and the least amount of confusion (i.e. represent pollutant
isosurface with key geologic features in the same view).
I know AVS can't not do this sort of thing. 

Any help would be very much appreciated.

A colleague of mine developed a multi selection system based upon the toggle
buttons.  I'm not sure exactly what he did, but you use toggle buttons in 
a column, and have two scroll buttons to go up and down (actually there were
4 buttons up, down top and bottom).  You need to maintain a separate list of
selected entries.  When scrolling, you change the title of each button
so that it looks like the buttons are moving down.  You'll also need to change
the setting of each button according to correspond to the setting of the object
they represent.  The most important thing to notice is that you only use 
(say) 10 toggles, and you map the list onto these buttons.  Don't try to 
dynamically move buttons etc 'cos it takes ages.

I'd post the code, but its part of some other stuff which is proprietry.

I've produced some ucd data that is composed of triangle cells.
Ucd print reports the same number off cells as my generating program.
However, when I feed the ucd data to "ucd to geom", the geometry viewer
says that there are almost 6 times as many triangles around.  Example:

   ucd_print:
	ncells: 1018 cell_veclen: 0
	nnodes: 531 node_veclen: 1

   geometry_viewer: Object Info
	Total Triangles: 6103

Now, for small data sets like the above, that's no problem.  However,
I've got a set with 144450 cells (aka triangles).  The resulting
865,000 triangle are quite a big problem for my system (SGI Indigo2 Extreme
with 64MB main memory only).  Even on a bigger machine (Onyx/RE2) where
I could try to visualize the data, it takes like half a minute until the
geometry viewer produces an image in its window.

Could anybody explain this mysterious data explosion or give me a hint
for how to visualize the 144450 cells in another way?

I'm using a demo copy of the AVS Animator, the goal being to make
animations to be downloaded to an Amiga.  I have the module "Write Any
Image" so I can turn AVS images into GIF, IFF, or anything else under
the Sun.  The problem is that "Write Any Image" seems able to take only
one filename at a time, while the Animator only saves its images into a
large sequence file.  Actually, there seems to be no way to easily make
AVS write a sequence of images as a sequence of files, named by frame
number, for example.  Am I wrong, or overlooking something?  My best
kludge at the moment is having "Write Any Image" generate a file with
input from "Read Squence" and to move the file out of the way in the few
seconds grace period.  This is rather gruesome.

You should be able to use the "Animate file name" module to
turn the frame number output by the read_frame_seq
module into a filename, which can then be pumped into 
WRITE_ANY_IMAGE along with the image itself.

So your network would look something like:

read frame seq
     |      |
     |      |__
     |        |
animate_file  |<-------- the image being passed
        |     |
        |     |
    --->|     |
    |   WRITE_ANY_IMAGE
    |
the frame number converted to a file name


All you'll have to do first is make the WRITE_ANY_IMAGE's
file name parameter port visible.  Just click on the
dimple on WRITE_ANY_IMAGE, then click on the file name parameter
port icon, then highlight the green string parameter port's
button to make it visible.  At that point you can connect
animage_file to WRITE_ANY_IMAGE, and you'll be all set.

I have changed the "Write Any Image" module in something like
"Write anim any image", which writes a sequence of images on disk.
De module will take as input an image and as parametres the base
name and the extension of the files which will be written on the
disk.

	     geometry viewer
		  |
          	  |
		  |
	Write anim any image

When the output of the "geometry viewer" will change the "Write anim
any image" module will generate the name of the new file in this
form :  base_name.xxxx.extension  .


If you want I can email you the module .

Regards,
 
 -Ion.

You should get from the IAC the "animate filename" module (in the inputs
directory I believe). It will take an integer input (use animate integer
perhaps) and feed a changing string output, which can be used as
filename input to the write any image module. This will allow you to save 
each frame as a different sequential filename. Another approach is to
use the "unix command" module to create a shell command that will move your 
output file to another (sequential) name. It as well takes integer (animated)
input allowing you to do the same basic thing.

VIS 1.0 Visualization System for X Window
=========================================

Looking for a free program to visualize 3D digitized images?

Here it is!

Brief list of features:
        * Allow interactive rotation, scaling, slicing, arbitrary clipping
          of the object geometry (the outline of the loaded volume).
        * Texture mapping of image slices onto the object geometry.
        * Distributed volume rendering
        * Isosurface extraction and rendering
        * Read NCSA's HDF 3D scientific datasets
        * Import Byte-stream data

The current release handles only 8-bit per voxel unsigned byte data
(i.e. 0 < value < 255).  We will be enhancing VIS to support other data
types soon.

VIS is now available in binaries only because it's not yet the
right time for us to release the source codes.  The binaries
compiled for SunOS 4.1.x and SGI IRIX 5.x are now available:

ftp.library.ucsf.edu
/pub/vis/vis-1.0.tar.Z

Binaries for other platforms will be available soon.

Since this is our first release, we don't expect it to work the way everyone
expects.  Please send any comments and suggestions to vis@ckm.ucsf.edu.

Thank you!

Hi there.

Is there a good way to do oblique projections using AVS ?
The standard projections appear to be only orthogonal
and perspective...

One possibility that occurred was to fiddle with the
projection matrix. This is settable by a GEOM library
call. Would this work ? If so, does anybody have a
suitable matrix ?

Thanks,

Vinod.

I have heard that there is an improved DisplacedLat
module out on the net somewhere which allows the
use of curvilinear lattices.  Can someone please give
me a pointer as to where to find it (either mosaic or
anonymous ftp site).

Thanks in advance,
Kel

I have data that I got from a CFD code that uses a domain
decomposition approach.  Each subdomain can be easily
described using an Explorer lattice, and I have been able
to build modules that can read the data for a specific
subdomain and output the lattice.  My question is this:
given a stream of lattices and the resulting geometries
from a given set of operations, how can I build a composite
geometry that can be displayed in render.  Because a large
number of subdomains are used I would rather not have to
build a group for the operations I want and load one of 
these groups for each subdomains.  

Sincerely,
Kel

I did almost the same thing with a couple of modules that I have
submitted to the IAC.  They are pictseq and rgbseq which output
sequences of PICT and SGI rgb files respectively.  I don't rely
on the firing of the geometry viewer, so they are really intended
to be used with the read_sequence module of the animator.  You
have to supply a base file name and a frame number, which the
read_sequence module does.  These modules use the 'old' way of
using the WRITE_ANY_IMAGE module.  The original version used the
SDSC libraries do the conversion, rather than the imconv program
itself.  This makes the code a bit easier to use (and adapt).  I
have also written a TARGA file sequence writer using the pbmplus
libraries (this one is all source, so it works on more machines).
Hope this helps...

I have just heard some details on AVS Express.  To say the least, it sounds
fantastic in capabilities and quite a departure from previous versions of
AVS.  We probably want the best of both worlds:  That is, we will want to
use Express but have lots of modules we have previously written to run
under the old AVS paradigm.  Can our old modules be mixed with Express
objects, etc. in a network without re-writing?  Are there other
compatibility issues?  What about data?  What about AVS 6.0?  Does it
continue the previous AVS paradigm?  Does it work better with Express (with
regard to the above questions) that AVS 5.0?
