Hi.

 I am now setting up a MRC Electron Microscope analysis softwares
on the Convex. And I want to use AVS as the visualization tools.
So, does anyone have a module that incorporate MRC format into 
AVS ?

 Thanks in advance.

Does anyone have a module that would take a sequence of 
AVS images and create 8-bit images on disk that all use the
same colormap?   The images could be TIFF, GIF, RLE, SUN,
FBM, but not (sadly) HDF.  I know I can output the 24 bit
images and postprocess with a quantization routine from
pbm or fbm, but I would like to find (or build) a module
much like Chas Williams hdf_mod that writes 8-bit images
on the fly (so as to save disk space for mongo animations).

The reason I have a need for this is that
I got the fbm2fli02.tar.Z package, which lets me create 
FLI/FLC animations from 8-bit images on a UNIX platform.
It needs the same palette for each image, however.

The FLI/FLC format is ideal for animations where a fair amound
of the stuff in the animation stays the same, since it stores
only inter-frame changes.

What is your field - uniform or rectilinear?  I've found that all my
uniform fields scale i,j.  I set extents, but I'm not sure I really
understand all the fine points associated with the extents.  My
rectilinear fields all scale just fine using x,y.  So that I'm using
rectilinear fields for my data -- and if I find I need to used uniform
fields, I'll whip up a uniform to rectilinear field filter, unless
some one already has one for me.

Nothing is wrong, you're using an ortogonal slicer to slice into a 3D
plan which has only on slice along one of the axis.  I just found this
last night and am now calling AVS about it.

Nothing is wrong, you're using an orthogonal slicer to slice into a 3D

I am in need of digitizing documents, photos, and "live" pictures (people).
Preferrably I'd like a clear color image, but I may have to settle for a clear

I believe I need something like the Canon Xapshot (with digitizer board),  Logitech Fotoman, or a video digitizer such as ComputerEyes.  If ANYONE could

I would be most grateful.

We are designing an instrument with a very large multidetector and are
interested in programmes which can be used for analysis, visualisation and
simulation of the acquired data set. On the the final instrument the data set
may be as large as 100 MB of integer data. The data is 4 or 5 dimensional and
we will require the analysis software to extract various slices/planes as well
as perform operation on large regions. We are planning to use a DEC Alpha 400
with about 128 MB of RAM as the computer system (running under VMS). The
software which has been suggested for this project is either AVS or IDL. From
the brief technical literature I have bothe are possible. Of course AVS
cost ~5 times as much as IDL. But It looks as if I'd have to do a lot more
work to get IDL to solve my problems.

Does anyone have experience of the two programmes and care to comment on
the advantages/ disadvantages, ease of use, value for money or anything else.
Once I get the new Alpha we should be able to play with demos of the
programmes but I'd like some input from other sources before that.

Hello all:
 I am a new AVS user and need some help .
 I met two problems as follows:

 (1)I made up a network in order to read a set of .pdb files continuously
    and then processed by pdb_to_geom and Geometry_viewer modules one by one.
    Finally the resulting
    image is saved by 'write image' module. But I encountered a problem that
    the former image will not be cleaned and the latter image will overlap
    with the former one. Is there any module that can remove the image of the
    former frame when showing the latter image frame?
 (2)We can use mouse to control the viewing position and direction when
    using Geometry_viewer. Now I wish to show a set of continuous frames. In
    order to obtain an animation feeling, the viewing position and direction
    should be fixed. But it is very difficult to select the same viewing
    position and direction by using mouse for different image frames.
    Is there any method that I can specify the viewing position and direction?


 ANY HELP WOULD BE APPRECIATED,THANKS A LOT .

Ah, I just love quoting myself!  AVS basically "accused" me of having
a "fake" 3D field.  Obviously, no one there ever thought a 3D field
could be extremely thin in a direction.  Anyway the gist of it all is
that the error message is harmless -- of course if your users are like
ours, and are concerned that the output they are seeing is accurate,
they will not like the "Illegal value" message.  

I've asked AVS how to dump this to /dev/null.  I've also pointed out
to them that my data is real measured data, and that we do wish to
view it, and that they should fix the orthogonal slicer.  We'll see
what comes of it.

I'm new to AVS. I'm looking for a 3D map of the world for use in 
AVS. I've been able to convert some data from the program
xearth (which got its data from the CIA worldmap database) so that
I have an outline of continents, major islands, and major inland
bodies of water (about 400K of data). What I would really like is
to have the continents filled (in green) and water in blue.  
The individual polylines that make up the continent outlines 
for closed "polygons".  There about 700 (or so) close polygons.

So, who out there has a world map in 3D.  I don't have the hardware
to efficiently handle a texture map wrapped on a sphere. :(


BTW, is there a FAQ for this group. My question must certainly come up
with regularity.

Thanks,

AVS 93 Video Review Theater


AVS 93 Video Theater Introduction
Chris Landreth, MCNC

Finite Element and Finite Difference Results
John Mareda and colleagues, Sandia National Labs

Sandia is using video animation and AVS to help them solve 
problems in engineering science. Applications are based on 
finite element and finite difference calculations in the 
areas of high velocity impact physics, shock wave physics, 
structural dynamics, structural mechanics, thermodynamics, 
and fluid mechanics. 

Silicon Band Structure
Franklin Bodine, National Center for Computational 
Electronics, Beckman Institute

This animation shows the first conduction band of silicon in 
momentum space.  An energy isosurface is colored according 
to the phonon scattering rate at that point.  The isosurface 
level is varied to show the energy range from 0.5 to 2.8 eV.  
A slice plane also shows the variation of energy in momentum 
space.  This conduction band data is vital to producing 
accurate simulations of transistors with high energy 
electrons.

Simulation of Hyperthermia-Induced Power Depositions Using 
FEM
Scott Clegg, Duke  University Medical Center

The essence of this video is a demonstration of the use of 
AVS to visualize the simulated power deposition induced in 
hyperthermia cancer patients.  The first part shows basic 
anatomical features of a patient whose treatment will be 
simulated.  The anatomical features (skin and bone) were 
obtained from a serial CT scan, which then had those 
features outlined for each CT slice.  The outline data was 
used to generate the surface rendered data seen in the first 
part of the video.  The second part of the video shows the 
finite element mesh that we constructed to simulate this 
patient; note the attempt to conform the mesh to the skin 
surface of the patient. The final portion of the video 
illustrates via isosurface renderings, the simulated power 
deposition.


Microburst
James V. Aanstoos and R. Jorge Montoya, Research Triangle 
Institute
Dave Bock, MCNC

Low-altitude wind shear poses a major hazard to aircraft 
during takeoff and landing and has been blamed for the loss 
of hundreds of lives in airplane crashes.  The NASA Wind 
Shear Model, also known as TASS/Terminal Area Simulation 
System, has been used to study this phenomenon as part of an 
effort to develop detection systems for these hazards.  The 
data used in the accompanying visualization was generated by 
TASS and initialized with meteorological conditions existing 
at the time of an actual microburst event, which caused an 
air transport crash near Dallas-Fort Worth Airport.

CM/AVS Sampler
Thinking Machines Corporation

CM/AVS is an extension of AVS that allows modules to run on 
the massively parallel connection machine CM-5 
supercomputer.  A module running on the CM-5 behaves like 
any other remote module and may be freely interconnected 
with standard AVS modules.

This video shows applications run with CM/AVS.  All were 
computed on the CM-5 and visualized with modules running on 
the CM-5 and various workstations.

Direct Methods in Crystallography
This video demonstrates the determination of molecular 
structure from experimentally determined X-ray amplitudes.  
Relationships between groups of phases can be minimized 
iteratively to modify random starting structures to produce 
correct final structures.

We show convergence first on a small molecule and then on a 
larger one.  Atoms in the unit cell are shown as spheres.  
Lines indicate possible chemical bonds.  As the structures 
are not fully refined, some spurious bonds are drawn; but 
the major features of the underlying molecular structures 
are readily apparent.

Interactive Flow Visualization
An interactive environment on the CM-5 aids visualization of 
results of 3-D fluid flow simulations.  The input is a set 
of precomputed time-discreet 3-D velocity vectors on a grid.  
In this case, data is from a numerical approximation of flow 
over and airfoil at a 50 degree angle of attack.
Tools provided mimic those in experimental apparatus 
(passive advection of tracer particles, bubble wire 
injection, and dye/smoke injection).

These four excerpts are taken from four chemistry animation 
sequences done using AVS.  The first two segments were made 
with the help of a module written by Roger Edberg.  The 
third and fourth segments were produced using some modules 
from AVS Chemistry Viewer (MSI).  All of the sequences were 
produced on a DECstation 5000/240 running AVS 4.0.  The 
above excerpts were produced in a collaborative project with 
Fujitsu Ltd.

Front Range Blizzard
Paula McCaslin, National Oceanic and Atmospheric 
Administration, Forecast Systems Laboratory

This segment shows an application of the use of AVS at NOAA 
Forecast Systems Laboratory.  It is a three-dimensional 
model forecast of the Colorado Front Range blizzard that 
occurred on March 8, 1992, and is viewed from southeast 
Colorado.  Each object used to investigate the data appears 
separately on the screen to emphasize the complexity of the 
end product.  The white isosurface depicts liquid water at 
0.6 g/kg and represents the area of significant clouds.  The 
red area within the cloud represents significant icing 
threat for small aircraft.  The script simulates a flight 
landing as Stapleton International Airport.  We approach 
from the northeast toward the southeast into Denver and are 
redirected south for a second approach.  The colored cross 
section depicts surface temperatures.  The white wind barbs 
indicate direction and speed of the surface winds.  The 
solid purple line shows the approximate location of the 
surface front.  Upper-level winds are displayed on two 
vertical line probes.  The station plots display actual 
observations and serve as verification for the model 
forecast.  The second approach is successful.  We fly 
through the red zone of ice, change the transparency of both 
isosurfaces, and land at Stapleton.

Exploring Dynamical Systems of 2-D and 3-D Ordinary 
Differential Equations (ODEs) with AVS
Alan Barnum-Scrivener, Advanced Visual Systems (AVS), Inc.

Since reading Chaos -- Making a New Science by James 
Gleick, I have been interested in visualizing ODEs (or 
change rules as Dr. Alan Garfinkel of UCLA calls them).  
After several false starts writing my own mappers to display 
a single trajectory of a system, I realized that the 
particle advector module in AVS allows display of many 
trajectories at once, giving a more global view of a 
systems behavior.  All I needed was a way to create a 
vector field based on the ODEs.  The elegant solution to 
this would to be to write a module that parses equations 
from an input text string and then generates the field.  (In 
fact, a student at University of California, Irvine, has 
done this, and the staff there have promised to donate it to 
the IAC.)  But meanwhile, I didnt want to have to write my 
own parser, so I used this kludge: I put the equations in a 
file in C syntax and then use a script to concatenate this 
file with pieces of code to create the source to an input 
module, which I then compile and read into a simple network.  
For example:

	xdot = y;     ydot = -x;

are the equations for a simple harmonic oscillator.  With 
this method, I can visualize any 2-D or 3-D system of ODEs 
in minutes.  Armed with this tool, I sat down with some 
books, including Dynamics -- The Geometry of Behavior by 
Abraham and Shaw, and just typed in equations and visualized 
them.  This technique allows me to reach an intuitive 
understanding of equations I cannot solve (often equations 
nobody can solve).

AVS Trial and Error
Joachim Biercamp, German Center for Climate Computation

This sequence is a compilation of geological and earth 
sciences data, particle traces, satellite data, and ocean 
wave spectra data from an ERS - 1 SAR wave mode image 
spectra.

Lubricating Air Flow Between Magnetic Head Slider and Hard 
Disk
Bunichiro Fujii, Sony Corporation

We visualized the numerically simulated lubricating flow 
between the hard disk and the magnetic head slider using 
AVS. The flow generates the pressure to keep the distance 
constancy between them. The distances are less than one 
micron in general hard disk drive systems. It is super low 
altitude. 

Carbon Monoxide Distribution in Los Angeles
Ruiyan Lin, Atmospheric Sciences Department, UCLA

This is a one-day time sequence of images displaying carbon 
monoxide distribution in Los Angeles.

Tracer Trajectory
Ruiyan Lin, Atmospheric Sciences Department, UCLA

This sequence includes two trajectories and their 
projections on the earth in different seasons.  The 
trajectory method is one of the most important methods used 
in atmospheric science research.

Mantle Convection
Lee Silverman, Brown University
Sea Surface Temperature
Lee Silverman, Brown University
Dans Head: A Late-Night Graphics Lab Hack
Dan Robbins and Lee Silverman, Brown University

The first video is a compilation of a series of test 
visualizations for the project that I described in the AVS 
newsletter (Volume 1, issue 4). The visualization is of 
motion in a volumetrically heated, turbulently convecting 
(Rayleigh number = 10e7), infinite Prandtl number fluid 
cooling from the top of a confining box.  In this situation, 
temperature is advected with the fluid, so visualizing 
temperature is a good way to see the motion in the fluid. 
The green surface represents an isothermal sheet drawn at a 
low-range temperature, the movement of which through time 
indicates that columns of cold fluid form at the top of the 
box and fall to the bottom, their descent unchecked by the 
volumetric heating.  The central plane shows warm halos 
around these cold columns, which indicate that hot fluid is 
being drawn down by the falling cold fluid. The bottom plane 
shows that the average temperature at the bottom of the box 
is lower than the average temperature of the middle of the 
box.  In this video, blue is the coolest and red is the 
hottest; but blue is only found in the centers of the 
columns, so the lowest temperatures are represented by 
green. 

The second video shows an animation of sea surface 
temperature data.

The third animation was created as the title suggests-- as a 
late-night hack.

CFD Simulation Using AVS-FLOW
ADAM NET, Ltd.

This video segment demonstrates the AVS-FLOW tool, which is 
used to visualize CFD results calculated by differential 
methods.  

Simulations Using AVS-Structure
ADAM NET, Ltd.

AVS-STRUCTURE is a powerful post processor system for 
complex structural analysis results.  It supports ABAQUS and 
NASTRAN data formats, in addition to its own.  Both AVS-FLOW 
and AVS-STRUCTURE run on top of AVS and were developed 
jointly by ADAM NET, Ltd. and TOSHIBA Corporation.

NRL Video Gallery
Upul Obeysekare and colleagues, Naval Research Laboratory

The four segments in this video sequence are as follows.
1. Volume visualization technique using ray-tracing is being 
used to visualize the time dependent results from a 
numerically simulated square jet.  
2. Computer simulation of a 3-D underwater explosion bubble 
broaching the free surface.
3. Results from a molecular dynamics simulation are being 
used to examine the momentum transfer and the associated 
relative motion between an atom and its immediate 
surroundings in dilute atomic mixtures.  
4. Molecular dynamics simulation of detonation in a solid 
high explosive with crystal defects.

Mount Redoubt Volcano Eruption Visualization
Dr. Mitch Roth and Charles S. Jones, University of Alaska, 
Fairbanks

The visualization portrays the eruption of Mount Redoubt, a 
volcano near Anchorage, Alaska, and the subsequent movement 
of clouds of airborne ash.  An eruption on the morning of 
December 15, 1989, sent ash particles more than 40,000 feet 
into the atmosphere. The animation combines the motion of 
the viewer with the time evolution of the ash cloud over a 
digital terrain model.  The ash cloud is rendered using 
volume texture mapping.   High particle densities are 
colored dark gray, and lower densities are light gray. The 
opacity of the cloud varies from opaque for high densities 
to transparent for zero densities. The rendering obtained 
through this texture mapping technique gives the viewer a 
visual effect corresponding to the particle densities 
involved. Details of the plume shape are highlighted through 
lighting effects, and the resulting geometry can be 
manipulated interactively to view the ash cloud from any 
desired direction.

The visualization is based on the output of a model 
developed by Dr. Hiroshi Tanaka of the Geophysical Institute 
of the University of Alaska and Tsukuba University in Japan. 
Using meteorological data and eruption parameters for input, 
the model predicts the density of volcanic ash particles in 
the atmosphere as a function of time.  The three-dimensional 
lagrangian form of the diffusion equation is employed to 
model particle diffusion, taking into account the size 
distribution of the ash particles and gravitational settling 
described by Stokes law.

The eruption animation of Mount Redoubt Volcano was produced 
using AVS on the University of Alaska Arctic Region 
Supercomputing Center CRAY-MP in a collaborative effort by 
Geophysical Institute and Arctic Region Supercomputing 
Center staff.

Molecular Orbital Studies
Douglas A. Smith, Department of Chemistry, University of 
Toledo

We have been studying the quantum structure-property 
relationships relevant to opto-electronic materials, more 
specifically the relationships of chemical and electronic 
structure to nonlinear optical properties of molecules.  
Through molecular orbital calculations and visualization, we 
have observed and cataloged specific changes in total 
polarizability, molecular orbital polarizability, and 
perturbations in the molecular orbitals themselves (shown in 
this video) as a function of a static electric field vector.  
Correlation of these observations with molecular structure 
in order to achieve a predictive capability is our current 
goal.

Molecular Dynamics Simulations of Granular Materials 
Hans J. Herrmann and Gerald H. Ristow, Research Centre 
Juelich, Central Institute for Applied Mathematics

This is a simulation of behavior of granular materials like 
lead beads, pills, powders, or grains of sand. Vertical 
vibrations (on a vibrating table with and without walls), 
outflow from a hopper, outflow from an upper chamber through 
a hole into a lower chamber of equal size, and flow through 
a pipe was investigated. Velocities of particles are color-
coded (blue - low velocity, red - high velocity). Fluid-like 
behavior, size segregation, and formation of density waves 
can be observed.

Molecular Dynamics Simulations of Polymer Systems
Kurt Kremer, Ralph Everaers, Norbert Attig, and Zenon 
Zowierucha, Research Centre Juelich, Central Institute for 
Applied Mathematics

Polymer networks are constructed of crosslinked chain 
molecules. The video shows the stretching and swelling of a 
model consisting of several interpenetrating polymer 
networks. A polymer is modeled as a chain of spheres. It can 
be observed that only a few chains take up most of the 
stress. The radii of the spheres are proportional to the 
amount of the bond tension acting on them. This is supported 
also by color coding (blue - low tension, red - high 
tension). When the tension exceeds a certain threshold, the 
monomers are connected by a tube. It can be seen that the 
tension is built up along a small number of paths through 
the system.

Dynamic Enhanced Recovery Technologies
Robin Reynolds and Roger N. Anderson, Global Basins Research 
Network, Lamont-Doherty Earth Observatory

The images depict hydrocarbon migration pathways in the 
subsurface of the Gulf Coast of the United States.  These 
streams represent a whole new production target, or PLAY, 
that could greatly influence our U.S. oil reserves estimates 
in the future.  At the present time, only the pools or 
reservoirs filled by these streams are produced.  The data 
sets used in this study are 3-D multichannel seismic 
reflection and well data.  The visualization techniques 
evolve from Supercomputer-generated Wavefront Technologies 
images, through IBM Power Visualization images, to the much 
more interactive and useful workstation/AVS imaging 
technologies.

Analysis of Doppler Radar Data By 3-D Computer Graphics
Hideo Miyachi, Kubota Corporation
Masayuki Maki and Hiroshi Ohkura, National Research 
Institute for Earth Science and Disaster Prevention

The recent development of 3DCG, the increase in speed and 
capacity, and the decrease in cost provide us many 
advantages in the analysis of the volume scan data od 
Doppler radar.  The sophisticated man-machine processing of 
3DCG releases us from tedious work such as programming and 
debugging  The perspective representation of radar data 
enable us to interpret the radar echoes more effectively and 
more intuitively.  We can call this type of display three-
dimensional indicator (TDI) corresponding to the naming of 
PPI and RHI.  When the time required for the image data 
processing performed in the present study will be shortened, 
TDI will be a standard display method of radar data.

Impact of Tunneling on the Groundwater Table
Harald Mayer and George Thallinger, Joanneum Research

The video contains live video sequences and four animations 
generated with the help of AVS. The four animations are as 
follows.

1. Isolines of pressure in a vertical cross section.
2. The groundwater table color coded by height during an 8 
week construction stop.
3. The moving groundwater table during the 20 week 
construction period of the tunnel.  Here the use of a 
traditional grouting method is simulated.  The groundwater 
table is color coded by height, additionally a gray bar 
shows the construction progress.  Particles on the water 
table show velocity and direction of the groundwater table.
4. This sequence shows with the same as above the impact of 
the advance grouting method.

Hi, 
	I was wondering if anyone can help me with a problem I am having
with the scat2d module.  I have x-y data plus a variable (in this case
elevation data) and I wish to plot a topographical map.  The data is
on an irregular grid.  I have read the data in as a 1D, 2space field,
and the scat2d module should be able to convert to a 2d-2space field.
(if I understand things correctly).  However, the variable (elevation)
is not transferred through the scat2d module (all I get out are zeros)
Any help would be greatly appreciated.

Thanks in advance,
Steve

Hi Folks,  here is a posting forwarded on for drk@curie.mda.uth.tmc.edu:

as a new user, my problems include
-comprehending the wealth of AVS options for analysing and displaying data,  
-picking the best way to do something;
-finding ANY available way to do it.

Typical questions...
		is there a module available?
		is there a combo of modules available?
		must a new one be written?

An NCSC index of AVS and NCSC modules sure would be nice?
One of those "in context" indexes would be even better.
Did I miss an complete index that already exists? 
The catalog and AVS .txt files are a start.



So...a specific problem for which I can not find a simple answer...


whats best way to extract one subvolume from another, 
so it can be used  by other modules?

Consider a simple 3D rect solid of data, 
	eg- organs in a body, intrusions in a geology model,
		clouds in the sky, gyres in the ocean

The problem is to extract and pass on the volume 
represented by a single data value (or range).

Possible approaches...

eg - an "iso-volume" module, like Isosurface, that will display surface 
of user selected data elements, and extract the voxels that would be
enclosed by that isosurface?

eg- an "iso-shell" , or "threshold-surface" module, 
that is iso-surface with controllable min and max values
which spits out all the voxels within the given limits.


and maybe after these, a manual way to "fill voxels in" or "erase voxels"
to take care of ....

those real world sub-volumes that are not "nice"?

eg- those volumes that would "leak", having holes in the surface.
patch over those one voxel wide?  two voxels wide?
User controllable?

eg- filaments extending from the surface.
Keep them?  ignore those one voxel wide?  two voxels wide?
User controllable?

eg- multiple subvolumes.
combine them?  extract separately?


(Once these tools are available, 
sub-sub-volumes can then be extracted from a subvolume
as necessary.)
-----------------------------------------

And how big is this subvolume?  
some of the stat modules look like they might simply count voxels, 
which would be ok once the holes/filaments/multiples were taken care of.

-------------------------------------------

what about a divide and conquer approach?

eg- contour slices of the volume, 
accept the smoothing done by the contouring to "kill" holes and filaments,
then stack them up to make desired volume shell.


is there an available  module to "fill in" inside 2D contours
so we could stack and make the volume?

a manual 2D erase/redraw?

---------------------------------------

Is there an AVS way already available to do this/these?  
What is your favorite approach?
I will summarize.

thanx

[Note: I posted a variation on this before]

Greetings,

I know that this is not proper material for the newsgroup, but these
are rare enough that it is uncertain how to proceed.

I presently own a Stardent Vistra 800 machine with the entry-level
graphics adapter and a 19" (60Hz refresh) monitor.  I realize that this
is a discontinued hardware line, and that Stardent transformed into a
software company working with AVS (and now called AVS).

   1) I am looking to upgrade my graphics subsystem from the '800b' to
      '800e' or '800ex' versions, i.e. to 24-bit color and possibly an
      accelerator.  (if available, maybe two such subsystems!)

   2) I would also like to obtain a Stardent 21" monitor, which was
      72Hz refresh, which since I use it a lot, would be a great
      improvement over 60Hz.

Towards this end, I would be more than willing to do a kind of "swap"
to get the better whole system (say, 24-bit plus 21" monitor), for
my 16-bit 'b' option plus the 60Hz 19" monitor...  plus a bunch of cash
to the person downgrading, of course.  One reason I mention this is
that the 21" monitor only works on the 24-bit card, which can switch
scan rates.  I would also be willing to just trade said monitors plus
cash.

I am willing to perhaps purchase a whole system (even minus
hard drives and such) to get the big monitor and 24-bit color and
possibly accelerator.

Thanks for your time.

Hi,

I am wondering if someone out there has generated datasets and the
associated modules to run on parallelized AVS 5.0 that they can
share.  I apologize if I got some of these terms incorrect as I am 
just learning AVS.  

I am planning a 4-node cluster connected over a network for 
SuperComputing '93.  I have heard good reviews about AVS and would 
like to see some parallelized AVS datasets running over this cluster.  
If someone has suggestions, I would greatly appreciate it.  

Thanks,

   - what types of application areas you are working in
   - how you have integrated your database with AVS
   - what capabilities are needed in AVS to simplify the integration process

Do I remember seeing a "wais" module in the respository?  I don't know if

What about "threshold" in the supported library?  (However, if you are
working with medical data as suggested by your signature, thresholding
techniques are usually disappointing, even with seemingly high contrast
data.)  For viewing, you could try a network containing something like
"compute gradient", gradient shade", "tracer", and "display tracker".

I've often wanted something like this, too.  Interesting problem is the
user interface:  how do you interact easily with these volumes using the
usual tools like 2D monitors and mouse/trackball?  Maybe VR will help.

Consider that there are 32 particles in a 2-D sample space. Each  
particle will be positioned by a 3-tuple (id, x, y), where id = 1,
..., 32. A configuration of these particles refers to a set of
(id, x, y). The AVS network of this application consists of two
modules as follows.

  +--------+      +--------+
  | source | ---> | viewer |
  +--------+      +--------+ 

The 'source' module will be programmed as a coroutine and it produces
a configuration per cycle. We suppose that the 'viewer' should draw 32
curves in a single window and each curve stands for the traveling path
of one particle.

Our problems are:

 - What kind of viewer should be used? graphic view or ...
 - How can we draw 32 curves in a single window?
 - What kind of AVS data format should be used?
 - Is there existing module for such application?

I hope the global picture of this application is clear enough to you.
Any suggestion? Thanks in advance.

I'm supporting a faculty member who uses AVS on a Sparc-10 with a
CGTwelve Graphics Card (aka, a GS accelerator).  The X server we
use is from the X Consortium, patched with XSun24-3.1 so it'll
work with the CGTwelve.  AVS's Hardware Rendering doesn't quite
work with this configuration: displayed images don't persist on
the screen, they show up for a split-second and then blink off.
This problem doesn't occur when using Software Rendering, but,
of course, animation is unbearably slow.

Does anyone use AVS with this setup?  Have you seen similar
problems?  Have you overcome them?

Try setting up what you want, delete the object and save the network.
That will save the viewpoint, etc.

Unstructured grids are difficult things to visualize, and AVS promises a
well-thought and comprehensive collection of tools for doing so. This is
why I have put in a serious effort over the last year or so to make it happen.

I have produced ascii UCD files from several applications: triangles in
xy space and xyz space, tetrahedra, hexahedra; with cell and/or node data;
with scalar, vector and mixed data; with and without material id's.
We have AVS4 on Kubota, Convex and Sun platforms. Sometimes one works,
sometimes another, sometimes none of them. I've tried REALLY HARD to
make the input file of the correct format.

The problem is that when I put AVS up to the feeding trough, it seems to
reject my file much of the time. Sometimes the read_ucd module flashes 
briefly and nothing is passed down. Sometimes read_ucd puts up one of those
generalized failure notices. Sometimes read-ucd works ok (and ucd_print 
prints out the right stuff), but then ucd_to_geom gets a generalized
failure. I have not managed to visualize cell data by any of the tools.

Does anyone else have these problems? 
Are there any hints about what to avoid in ucd files? 
Is there any way to find out WHY a failure occurs, rather than just 
	this beeping notice?
Is it possible to get source code for ucd_read, ucd_write, ucd_to_geom so
	I can instrument them myself?

I had a similiar problem of having x-y data plus a variable which
originally came from a finite-element grid. I wanted to treat it as
scattered data, and have scat2d generate something appropriate for the
geometry viewer... NO WAY! I ended up (with help from AVS folkes)
using a new module available from the AVS repository called
scat_to_tri which creates ucd data that can be fed to ucd threshold
and finally to a geom viewer. This doen't create a surface plot but
with the appropriate colormap stuff you can see your data as colored
2-d image.

     In our medical imaging group at the University Hospital Gasthuisberg,
  we must process large datasets (3D images resulting from CT or MR scans).
  We are currently evaluating AVS, but before actually buying it we need
  an answer on the following questions:

   - Each module in AVS allocates memory for its output nodes. In our case
     we are using images (fields) which are typically about 50 Mbyte large.
     Although our RS6000 has 192Mb RAM, this limits the number of modules
     we can use in a network. We only know about one way to 'reuse' the
     output field of a previous module, namely by using shared memory and
     by setting ReadOnlySharedMemory to 0. By doing this we can overwrite 
     the pixel values, however this can only be done for modules we have
     written ourselves. If we use other modules, how can we free/reuse the
     memory when it is no longer needed???

   - Another question concerns the lack of documentation of the built in
     modules/functionalities of AVS. e.g. We want to know how the 3D volume
     rendering is actually implemented (the algorithm used, what do we need 
     to define in the uniform field format when rendering medical images
     with different size along each dimension?, etc.). 

     How can we obtain this information?

  Please send your answers to me by E-mail,

Yes you can do this.  The easiest way is probably to do a Save Scene and then
alter the script created.  Save Scene creates a CLI script which you can alter
and add to.

The first few lines set the camera, lights and rotation/scaling
of "top".  The lines that follow are grouped for each object: they read, alter
properties etc of each object in the scene.  To remove these references, simply
get the scene script into an editor and remove all such blocks.  In my files,
everything after the geom_set_position is a referenc to an object, except
for the last line, geom_refresh (which you may or may not need !).

You'll want to delete the geom_create_scene from the top of the file to make the
script act on your current scene.

Check out the CLI section in the developer's guide.  There is, in fact a veiled
reference to your question on page 5-24 "saving/restoring scenes and objects".

Hope this helps

	About this time last year, I began working for a professor who
is doing fluid convection research, and started on a quest for an AVS
module that will allow me to visualize the motion of a particle within
the vector field generated by the flow.  If the flow were static, the
Particle Advect module would be fine.  However, the flow field changes
with time.  I can read the entire field in as a 4-dimensional
hypercube which can be "sliced" into 3-D vector fields representing
velocity, but I can only do advection in each of these fields
independently, not as a group.

Has *ANYONE* written a module to do this?  It seems like something
that a lot of people would want to do, so I can't understand why such
a module doesn't exist.

Thanks in advance for any information y'all can give.

Is this something to do with maybe having to have Sun's DGA extension to

this behavior results from one of two conditions (typically):

first, the scat2d module requires you, the user, to specify the
corners of the output grid.  if you specify a grid that doesn't
surround or enclose your data, you won't see anything but junk.
similarly, if you set the search radius size to something 
inappropriately small, you'll see junk.  chances are, this is
not the case because these two conditions generally produce
"junk", not zeros.

more likely is the condition where the numerical routine isn't
actually being executed.  there are some ifdef's in the code to
allow for the different naming conventions used by C compilers
when calling fortran code. 

the way to figure out what's going on is to use the debugger
and step through the code to make sure the parameters are ok
(the grid surrounds your data, the resolution and search
radius are such that some of your input data is actually
used by the numerical routine), and that the numerical routine
is actually being called.

I'm about to make what has become a tougher decison than I originally thought about
purchasing a visualization workstation.  To cut to the chase, the decision comes down to

		SGI "Jurassic Classic" Crimson (R4400 + VGXT)

					vs.

		Kubota Pacific Denali 4/10 / DEC Alpha 3000/500

The primary purpose of the machine is to use AVS to visualize 1-100Mb datasets.  (No, we
can't afford a Reality Engine.)

The two systems are almost equivalently priced (at least according to my quotes), and I
think the decision rests upon software stability vs. hardware performance.  That is to
say SGI seems to be a more stable platform, but the Kubota seems significantly faster.
Anything else I should be aware about?  Any opinions?  We'll make the decison next week?
I'll post it.

I need to make a raster image file which is higher spatial resolution
than the screen so that when I feed it to a Tektronix Dye-sub printer,
it results in full 300 dpi. Is there an AVS module which can produce
a such a file (in tiff, rgb, cgm or other) ? Postscript files produce
too much dithering.
Thanks

Subject: Leo (ZX) support in AVS story

This is the story with AVS support for Leo (aka ZX).  

We (AVS Inc) are currently working on AVS 5.01 on Solaris 2.3 (SunOS 5.3)
that will support hardware rendering for the following SUN graphic
accelerators:  ZX (Leo), GS, GT, and SX (Spam).  This will be
available before the end of December on CD-ROM .

BUT, please keep in mind that AVS will behave as good as SUNs XGL
library interface with the graphics board.  SUN made many XGL corrections
in Solaris 2.3, which is why we are strongly recommending a Solaris 2.3
upgrade before installing AVS 5.01 for ZX support.  Please plan 
ahead for our December release.

In the meantime, we did release AVS 5.0 for Solaris 2.1 back in
June '93, that was tested for software rendering only.  However,
there is a switch that can do hardware rendering; enable by:

                    setenv AVS_USE_HW_RENDERER

But since this release was done in June (pre-Leo), you may find
some glitches.  

The rule-of-thumb is, when a system vendor releases software
(Solaris 2.3 + XGL) and hardware (ZX), it takes roughly 2-3 months
for us to port + test + release AVS to support the new system(s).
Over the past few months, we have been working with SUN to shake 
out some XGL bugs, now fixed in Solaris 2.3 (libxgl.so.3).

Let me know if you have other AVS concerns,

Lou.

I would like to know whether AVS is a suitable package to visualise
abstract geometric data.  At present my data consists of a large number
of nodes with directed connections between them.  The nodes and connections
are not related to any physical picture.  I would like to represent the
nodes and connections in 2D or 3D and then have modules that can 
isolate different patterns in the node data and highlight them (say by
colouring particular connections).  I would also like modules that could
identify sub classes of the nodes and connections and then represent them.

Is AVS suitable for this kind of visualisation?

     I'm trying to port a few modules to a DEC Alpha workstation
with a Kubota hardware renderer and am having trouble getting the
source to compile properly.  The modules I'm particularily interested
in are WRITE_ANY_IMAGE and contour_to_posts.  However the problems
I'm having seem to be universal and linked to the sdsc files required
for compilation (my own modules and those which do not use the sdsc
files compiled fine).  I have copied all the files from sdsc and put
them where the docs say.

     The compilation error I get regards unresolved functions
or variables:  ImVfbAlloc, TagTableAlloc, TagTableAppend, TagEntryAlloc,
ImFileFWrite and ImVfbFree.

     If anyone has successfully ported code which uses the sdsc
code to a DEC Alpha or knows what my problem may be I'd greatly
appreciate some input.

Thanks in advance,

The current version of AVS (AVS 5.0 for Solaris 2.1, revA) was
released in May, and partially supports Leo (ZX).  HOWEVER, we are
putting the final touches on AVS 5.01 for Solaris 2.3, revB, that
does support hardware rendering; Leo (ZX), GS, GT and SX.  The rule-of-thumb
is when a system vendor releases software to support a board (in this
case, Solaris 2.3 with XGL to support the ZX), we need several weeks
to port AVS, test it and release it. 

Until then, with the version you have now, you can:
    % setenv AVS_USE_HW_RENDERER

But be aware that AVS is as good (as fast) as the XGL library is;
on Solaris < (less than) 2.3, the XGL library underwent many changes,
which, in turn, effected AVS.  But XGL seems to be "stable" in 2.3 .
In general, we recommend Solaris 2.3 (SunOS 5.3) for AVS; not 2.2 .
Something to keep in mind for future OS upgrade planning.

So AVS 5.01 for Solaris 2.3 (with ZX support) will be released on CD-ROM
in December ( < 8 weeks); the tape will be available before then.  If you
have a valid AVS Support Contract, then it will automatically be sent 
to you.  Email to support@avs.com to assure that you're in our database.

Enjoy AVSing!

The AVS party-line line is that we support whatever the hardware
vendor supports.  In this case, SUN supports Openwindows, not X11,
so AVS supports Openwindows.  I believe SUN *will* support X11R5 in
SunOS 5.3 (Solaris 2.3), so this should resolve your AVS with X server
woes on the SUN.  We are releasing AVS 5.01 for Solaris 2.3 in December.

   Hi everybody,

 I'm trying to write a module that writes an AVS image (AVSfield_char *) in
the mac PICT2 format. I know some modules at ncsc.org do perform this
conversion, unfortunately the libs needed are not compiled for my platform
(a Stardent Vistra 800e) and the sources are not available.
 I already suceeded the conversion, but only with less than 256 colors. I
would like to keep the 16 millions (possible) original colors by using the
32-bits coding mode. I have a lot of information on this subject, but don't
suceed in doing things work. I don't want to waste my time on such down-to-
earth problems, so I'm looking for C sources or (very) precise informations
on the subject. Can you help me ?

   Thanks by advance.

Hi :
	I am new to avs and need to know how to compile and link a FORTRAN
	program using AVSCOMMAND.

	The test program is as following 	

	program test
        include '/usr/um/avs5.0/include/avs.inc'
	character*20 dest,commb
	character*500 outb,errb
	dest = 'kernel'
	commb = 'geom_refresh'
	i =  AVSCOMMAND(dest,commb,outb,errb)
	end


	the command I used to was (according from what I know from manual)
	f77 -o test.exe test.f /usr/um/avs5.0/lib/libflow_f.a

	The error signal was : 
  
	MAIN test:
        /bin/ld: Unsatisfied symbols:
        avscommand (code)

	What is the correct command I should use to compile and link this
	8 line program ? Which library is for AVSCOMMAND ?
