AVS4, DEC5000/240PXG, Ultrix 4.2A.

i am trying to advect some particles around in a velocity field, and it
seemed to me like the 'particle advector' module would be a good choice
for this.  i am providing the particle starting locations with the
'samplers' module, and therein lies the rub.

i want a small plane of starting points at the bottom of my velocity field.
the avs manual leads me to believe that if i wish to generate a plane
smaller in extent than the data set, i need to pass the field through crop
prior to samplers.

i've done this, net follows.  it doesn't work.  the sampled
plane/volume/circle/line always extends over the full extent of the volume
bounds (the particle advetor's 'show bounds' is set on).  has anyone else used
this kind of setup?  anyone have any idea why this might not work?

  I'm trying to control camera motion in the geometry viewer from the
CLI.  Unfortunately I find the documentation on the geometry viewer CLI
interface largely incomplete.  Can anyone provide advice on the following?

    I want the camera to swoop down on a volume rendering (produced by
the "render volume" module), enter and pass through the volume, and out
the other side.

   Can anyone suggest specific CLI command sequences to make this happen?

I'm writting a coroutine module that has two outputs.  The first is 
designed to provide a control line to signal the start of the computation loop 
while the second is the data output and is sent to the port each time thru the 
loop.  

Example:

    while true do
      AVScorout_mark_changed()
      AVScorout_wait()
      AVScorout_input(a_param) 
      if a_param = 1 then
        control_line = 1
        AVScorout_output(control_line, data_output)
        do n=1,100
          data_output = random
          AVScorout_output(control_line, data_output)
        end do
      end if
      control_line = 0
      AVScorout_output(control_line, data_output)
    end while

The problem is that this will cause the network exec to ding the module 
connected to the control line port each time thru the loop.  Is there anyway 
to stop this and just output to the data port or to suppress the network 
executive from passing the control line while still allowing the data piece of 
the network to execute?

I'm interested in looking into using
systems such as AVS on civil engineering monitoring data.  We
have several gigabytes of data stored as time histories from
multiple instruments.  It would be very interesting and
hopefully illuminating to superimpose this on an image of the 
structure (possibly but not necessarily from an FE model).

My questions are:

1.  My impressions are that one of the main problems is getting
the data into the system - is this correct?

2.  Is this merely a trivial problem anyway?

3.  Has anyone done it already?

Thanks,

Andy Vann.

	I am putting together case studies and examples for a
scientific visualization book along with several other authors.
The approach will be from a data perspective with demonstrations
of visualization techniques useful dependent upon data type.  For
example, it will start with 1D, then 2D,3D...nD, scalar, vector, tensor,
uniform, rectilinear, scattered, and so forth with as many combinations
of data types as possible.  The first questions most users as are,
how do I get my data in a form that I can visualize, or here is my
data, how do I visualize it?  Rather than a discipline specific approach,
this will be a data specific approach.

	I am interested in getting as many participants as possible with
as many data types as possible.  Lots of example images will be requested
for each data format, and an explanation of how it was accomplished and
the value of this particular visualization method on this type of data.

	Please send me some email if you are interested in providing some
data, images, short writeups of your work with focus on vis techniques, 
tips and tricks, etc.  More detail will be provided to those interested in
being published.  This will be the 3rd part of a large scientific
visualization users guide that should be done by spring.  Credit will be
given to participants as appropriate to their organization.  We hope to
make this the primary guidebook for users interested in scientific 
visualization.

Greetings,

	We have been visualizing various weather data with AVS and are pleased
with its performance.  However, we cant seem to get good geographic maps mapped
onto our "surface".  Anyone out there who could give us some good ideas on how to 
incorporate geographic maps into a 3D data set with the geometry viewer?  We 
already have elevation data meshed as our surface, we just need the map "mapped"
onto the surface!
	I've experimented with converting customized gif maps into x format, then
texture mapping it onto the surface.  This is time consuming and doesnt show up
well unless the map has very thick, dark lines.  Is there a way to plot the 
lat/lon map data to match up with our data set?  Example networks and datasets
are welcome.  Please respond to me directly if possible.

Thanks "a priori",

There is a cli command within the Geometry Viewer called "geom_save_postscript"
that can save a view into a ps file with PostScript objects.  You have to 
use the Software Renderer to use this command.  Reference is in pp 5-32 of the 
AVS Developer's Guide.  One thing you have to be careful about is the 
background color of the geometry viewer window.  Default black color will 
produce a black background in the print.

Is there an option in the Geometry Viewer for antialiased lines? Usually
you have a choice of goraud or flat shading, wireframe, or antialiased 
lines, but I guess the antialiased lines will only work on systems with
hardware antialiasing (at least it was that way back in AVS 3, don't know
if they've added anything for software antialiasing since then).

There are two modules on the ftp site (avs.ncsc.org, 128.109.178.23)
that should help with this:

Name        : cylinders       Version      : 1.000     Mod Number : 1298
Author      : Eric Sills, North Carolina Supercomputing Center
Submitted   : 08/26/92        Last Updated : 08/26/92  Language   : C
Module path : avs.ncsc.org:avs_modules/data_input/cylinders
Ported to   : Convex Sun DEC HP
Description : Cylinders reads a file containing cylinder center point
              coordinates (x,y,z), cylinder radius, and cylinder
              height, one per line of the input file. Cylinders builds a
              polyhedron object for each cylinder (surface normals are
              computed for shading).

Ported to   : IBM Convex Kubota DEC HP
Description : This module maps a 2D input field along a (portion of a)
              cylinder. If the input field is UNIFORM, the y dimension
              gives the number of subdivisons of the circle and the x
              dimension is the depth of the cylinder. If the input field is
              rectilinear, the x positions are taken along the cylinder
              axis, while the y values are positions around the circle,
              given in degrees. direction give the sphere subdivison.

Good luck with it...

I have written a coroutine that needs a filename at startup
I start AVS with the script command :

avs -cli "script -play script.scr"

and I want something like this :

avs -cli "var_set filename name"; "script -play menu.scr"

but AVS does not accept that.

The problem is : How to start up AVS with two CLI-commands ?

Hello.

I am a new user and am having trouble getting AVS
to perform the following task.

I have irregular data in the form (X,Y,Z,value).
I want to display this data as a 3D image, so I
need to map this data to some kind of regular 
array prior to displaying it.  It is sufficient
to simply impose a regular grid in the same volume
as the data and merely assign the irregular data
points to the nearest point in the new regular mesh,
averaging multiple values mapped to the same point.

HOW DO I DO THIS IN AVS????  More generally, what
modules are useful for viewing 3D irregular data
(besides the scatter dots/bubbleviz combination.)



I would greatly appreciate any clues to help me
solve this problem!!!

Thanks much.

Chris Lanczycki

There have been some recent postings to this newsgroup about an
ongoing project at Advanced Visual Systems called "IVAN".

"IVAN" is the next major release of AVS, and is an internal project
name for this development effort.  The name is not an acronym, it
is just a name.  The official name of the new release will be AVS6.

AVS6 has many exciting new and improved features, including:
        + Motif support
        + PEX and OpenGL support
        + Windows support
        + extensible and modifiable viewers
        + improved user defined data
        + volume rendering enhancements

Advanced Visual Systems has a proven track record of releasing major
new versions of our software every year.  AVS6 will maintain this
tradition.

Please understand that this message is not a product announcement,
but rather an attempt to quell curiosity about our current development
initiatives.  More details about availability and specific features
will be made public at the time of product announcement.

I want to read sun raster images into AVS. In particular I want to convert
raster files from sceen captures to TIFF or PICT fromat. After compiling the
user subscribed module "read_sunras" abtained from avs.ncsa.org, I have
not been able to open a screen capture made with "snapshot".
The module links OK in the network editor, but clicking on a filename
in its browser doesn't seem to do anything. There is no read
button in its panel to activate the choice of file in the browser.
I note there is an alternative module called "read_ras_image". It
requires for compilation certain library files at an ftp site
that is not currently responding (ftp.sdsc.edu).

Any suggestions?

Does that mean that AVS will be less of a memory hog?

  Version 1.2 of our Line Integral Convolution (LIC) software is now
available.  This supercedes the version which was released on the
SIGGRAPH '93 conference CD-ROM.  It also supercedes the version which
has been available informally for about two months via anonymous ftp.
This is the final version that we plan to release.  We hope that
vendors supplying image processing software systems will take over
from here.

  The new software is available via anonymous ftp from the machine
LLL-CRG.LLNL.GOV in the tar'ed compress'ed file pub/lic.1.2.tar.Z.

  The copyright terms are very liberal.  They basically amount to: ``You
have to give the Regents of the University of California credit if you
use the software and you can't blame us if anything goes wrong.'' Other
than that, have at it.  See the copyright notices for all the standard
legalese.

  This new version has lots of little fixes all over the place.  The
biggest single change is the fix to make ``variable speed''
convolutions work (it basically didn't work at all in version 1.0).
These changes that make it worth while to pick up this new version.
See the file CHANGES in the top level directory for more information
on what's changed since the first release.

  For those of you who are unaware of what Line Integral Convolution is,
here's a brief blurb:

    The LLNL LIC software distribution is an implementation of the
    Line Integral Convolution algorithm.  Line Integral Convolution
    can be used to visualize vector fields and generate a variety of
    unique special effects.

    Vectors are visualized by convolving an input image along vector
    stream lines in an input vector field.  The result is an image that
    looks like the input image, but blurred in the directions of the
    vectors in the vector field.  For a thorough explanation of Line
    Integral Convolutions see ``Imaging Vector Fields Using Line Integral
    Convolution'' by Brian Cabral and Casey Leedom in the SIGGRAPH '93
    proceedings.

    This software system consists of a library that implements the LIC
    algorithm, a command line interface and an AVS coroutine module
    interface.

    Where possible, this software has been written to conform to ANSI C
    as defined in ANSI X3.159-1989 and POSIX 1003.1 as defined in IEEE
    Std 1003.1-1990. ...  At the time of this writing the software has
    been compiled and tested on HP Snakes running HP-UX 9.01, IBM RS6000s
    running AIX 3.2, SGIs running IRIX 4.0.5 and Sun Sparcs running SunOS
    4.1.1.  The previous version of the software also ran on DEC Alphas
    running OSF1; the current version should port to the Alpha platform
    without any major problems.

  We hope that this software proves useful to you.  If you have any
problems, feel free to contact us.  While we don't plan on making any
more formal releases, if there's interest we'll set up a LIC interest
mailing list for people to exchange information, problems, etc.  If
interest is low, we'll just put your name down and contact you with any
news, bug reports, etc.  Please send mail to Brian Cabral if you're
interested in this.

Hello,

Do any of you AVS programmers out there have a "cookbook" type recipe for 
allocating output port memory?  I have written a couple of modules and am
able to do this using AVSinitialize_output for some cases, but for the case
that my output port has a different size field array than the input array
I can't seem to get anything to work.  I can actually create the output
field and write data to it (and print data out from it), and it compiles
OK, but when I try to connect the output port to something (like "print field"
or "statistics") it crashes the network (not just one module), and in some
cases AVS.  It receives and processes the input just fine.

Thanks,

Have you tried using the UCD modules in AVS?  This seems
like a perfect match for the field to UCD module.
Just look in the help for that module, and it will
describe how to convert your 3-D field data into 
UCD and display it on the Geometry Viewer.

There are two modules by Wes Bethel at IAC called scat 3D and trivar
that maps irregular data into a regular grid.  This might be what you
want.

This isn't a direct solution to your question, but here goes anyway:  How
about starting avs with the server option and using avs_client (see
/usr/avs/examples/avs_client.c - at least that's where it is on our
GS-2000) to pass cli commands to the avs kernel?  It does involve an extra
process and some extra coordination, but it gives you plenty of
flexibility.

I'm trying to write a network to generate an animation by driving
the camera around over some topography and data.  The end of my network
looks like this:

             -----------------       
             | geom viewer   | 
             -----------------
              |            |

       -------------    -------------------
       | Camscript |    | write frame seq |
       -------------    -------------------

where Camscript is a coroutine I wrote to send CLI commands to move
the camera around and is connected to the trigger output of the
geom_viewer.  The problem is that Camscript generates a new frame 
asynchronously and too quickly for write frame seq to finish outputing
the frame.  Is there any way to get Camscript to execute after write
frame seq?  Unfortunately, write frame seq doesn't have a trigger output...

Thank you in advance (and afterward too, unless I get ten thousand
replies :)

There is a routine called "AVScorout_set_sync" (pp. A-29 AVS Developer's
Guide) that you can use to force a coroutine to execute synchronously.

Hello...

I was waiting for the installing of DEC AVS 5 from AVS, Inc. to post this message
to see if anyone has noticed the following problem and maybe found a work around.
Maybe also to stimulate some revisions on AVS, Inc.'s part:

We are running DEC AVS 5.0 on our DEC 5200 PXG machines.  I noticed in the past that most of the fonts in the label part of the geometry viewer didn't work.
Now with 5.0 I notice that they continue to be un-usable for example with
symbol fonts.  Since this is important to people wanting greek letters..

Anyway, unlike before I can get to these fonts if I use the software
renderer.  However, there is still a problem with the size of the fonts.
Using the symbol font under the software renderer I get cut-off letters
(like b -beta) unless I choose certain fornt sizes only.

Is there a workaround to either problem:  I want hardware rendered greek letters
or at least the ability to choose the size of the software rendered letters.

CALL FOR ATTENDANCE.


ADVANCED TECHNIQUES FOR UNDERSTANDING, PROFILING, AND DEBUGGING OO SYSTEMS

A one-day workshop to be held at OOPSLA '93
Sunday, September 26, 1993
12:30 - 8:00 PM
Washington, D.C.
U.S.A.


PURPOSE AND GOALS FOR THE WORKSHOP

As object-oriented systems become larger and more complex, it is
becoming increasingly important to leverage audio and visual techniques
in tools for program understanding, debugging, and tuning.  When
profiling a given OO system, visual techniques become valuable, even
indispensable, when determining clusters of instances or classes that
appear to consume most processing power. The majority of the
relationships between object instances are naturally expressed in a
visual fashion.  Therefore, it seems logical to use visual techniques
for monitoring and debugging OO systems. Another potentially
appropriate technique is sound. Sound might have a wider information
bandwidth than text, at the very least it has an attention getting
power that is quite useful.  Other techniques might very well included
virtual reality or sensory inputs other than visual or audio.

This workshop will bring together people that have developed advanced
techniques other than textual to enhance the understanding of an OO
system, or to improve its execution or correctness.  The different
techniques will be presented to the other attendees and their
individual applicability, strengths, and limitations will be
discussed.

We are convinced that this topic is exciting. It is an interesting AND
necessary area to explore.  Displaying networks of object instances,
maybe customized representations of objects that are normally difficult
to trace as they are manipulated during the execution of the system?
These are all definitely important issues. Discussions should be
started to gain ideas about how to obtain generally applicable tools to
be added to existing object browsers and debuggers to equip them with
more powerful visualization techniques.

PARTICIPANTS

The proposed attendees are researchers that have developed advanced
techniques for investigating running OO applications. People who have
been actively involved in the implementation of such techniques and
have experience with applying the techniques in "real-live"
applications are especially welcome.

WORKSHOP FORMAT AND LENGTH

The position papers for the workshop will be sent by email to the
attendees prior to the workshop so everyone will have the possibility
of preparing themselves in advance for the workshop. During the
workshop, a limited number of presentations will be given by attendees
that have been invited to do so by the organizers. Of course, visual
presentation techniques such as video could be used. The presentations
will serve as a catalyst for discussion. The workshop will have a
limited number of presentations to ensure that subjects can be
discussed in depth and that discussions do not get dispersed over too
many aspects.

POSITION PAPERS

All participants must submit short (2 page) position papers to the
workshop organizers.  The paper should briefly describe your specific
techniques and how they enhance the understanding of OO systems or
contribute in profiling or debugging them.  Papers must be submitted by
August 20, 1993.  Participants will be selected and notified by Sept.
15, 1993.  Position papers MUST be submitted by email, in ASCII.  It is
highly recommended that position papers be accompanied by relevant
technical papers. The distribution of these papers at the workshop is
left to the attendants.

Here we go - take 2...

Are you interested in stereo pair image generation, using a stereo
device hooked up to the monitor, or something like red/blue or random
dot stereogram images?

AVS5 can do stereo image generation on the Silicon Graphics workstations
directly (go into the Geometry Viewer window and hit Ctrl-Left Mouse
Button) which only helps if you have an appropriate stereo headset 
hooked up to the video display.

If you are generating images for 35mm slides (or whatever), you can
simulate this by creating two cameras offset from each other in the
X-direction about 4 cm (assuming that your world coordinates are in
centimeters...)

I recently wrote a module called 'stereogram' which uses the Z-buffer
output of the Software Renderer to drive the left/right eye separation
for the generation of a random dot stereogram.  I'll send this down to
the IAC (avs@ncsc.org) later today.  That might be interesting for you
as well.

If you don't want to take a hooked stereo device on your monitor, or for 
first experiments you can do it like this:

After computing the two stereo half-pictures with the objekt tunrned around 
a vertical axis with maybe about 10 degrees, you can place the pictures side 
by side and look at it on the screen through a stereo lens pair or a 
stereo viewer (with a mirror or prisma optik).
You maybe can get more information about it in a "photographik" newsgroup 
in connection with conventional stereo photography.

I am looking for a method for determining the points
where a 3d geometrical object intersects a 2d plane.
Hence, I want to extract a 2d contour from a 3d object.
Is there a reasonable way to do this using AVS?

Another possibility would be to give the lines some kind of priority in the

Try the "tube" module. I am not sure if its part of the standard AVS modules.
If not it will be available via ftp to IAC. This module converts lines to tubes
of a thickness that is user defineable.

The consensus is to use the "tube" module.  I have not tried it and
it hid from me when I scanned the module list!  If it does the trick, I
will be very grateful.  I have been warned that it ha a bug in AVS4.
We shall see.

Thanks to all who replied!

 AVS users:

    Please help me !
    I am a new user of AVS.

    I wrote a small program in C called cout.c which displays a 2d image by creating a
    module called "mat out" IT WORKS FINE.

    THEN I wrote an equivalent module in FORTRAN which is giving me trouble. If somebody
    could help me finding what I am missing in FORTRAN module, I will appreciate a lot.

    Both working C and not-working Fortran modules and their corresponding makefiles 
    are listed below:

                        mat out
                           |

                        field to byte

I want to animate some images computed by AVS on an Ultranet Frame Buffer from
a Convex C2 via Ultranet from UltraNetwork Technologies.
Does somebody here have experience with this subject or maybe a module,
which displays an image on another Frame Buffer System?

Is there a module available like the IMAGE MANAGER which has also a DELETE-

please send a mail, if you can help me.

My module assigns default colors to the objects it creates, and I would

If you set the colors to GEOM_NULL, the Render Geometry module can set the
colors without any problem.

One of our AVS users mentioned that she had been told by a person at AVS
on how to group two or more objects in the geomrty viewer into one new
obect that can then be transformed, etc.  as needed.  The command was
apparently given at the prompt.  Does any one know about this?

I have an application in which a 2D image is required to be displayed
and exported with a number of overlays: contours, motion vectors,
grids, axes and text annotation.  While I can obtain a display of all
these items in the image viewer, by extensive use of the CLI, I have
problems obtaining a hardcopy and output raster at the same resolution
as the input.  Starting with say a 1000x1000 image I want to create a
raster of the same size containing all the annotations, for export to
other (simple) display packages.

The image viewer output (which seems unreliable) is at viewer
resolution, i.e. my input 1000x1000 image will be smaller.  Linear
features can be created in raster, but text annotation seems to be
difficult.  I want to avoid creating special purpose X applications.
Anyone got any good ideas for producing a 2D field containing all the
annotation at input image dimensions? Many thanks.

The cli command you are looking for is:

   geom_set_parent {-object <name> } [-mod <module> ] parent_name

For instance, read in three objects: harmonic.0, dodec.1, teapot.2.
Then you can reparent the harmonic to be a child of the dodec:
	geom_set_parent -object harmonic.0 dodec.1
and then the dodec to be a child of the teapot:
	geom_set_parent -object dodec.1 teapot.2

and if you look at the Object Browser, you will see the hierarchy
expressed as:
    top
       teapot.2
	  dodec.1
	     harmonic.0

Selecting and Transforming any object will transform that object and
all its children.

I hope this helps,
larryg
