I think you are linking a wrong library file. 
libflow_f.a is made for subroutine module, thus contains main routine. Try
to link libsim_f.a instead.

Hi,

I'm developing an visualization tool using x/motif. It'll be used to
visualize the internal activities of an multithreading operating system
called nachos. I'm planning to visualize things like semaphore queues,
memory map, multiple address spaces etc.

Does anyone know how to make nachos communicate with the motif
visualization tool? For example, when nachos brings a page from disk
to memory how does it "tell" the visualizer to update the relevant
graphics? 


Please, please reply by email (aleung@das.harvard.edu) since I'm
spending all my time working on the visualizer.

We use AVS routinely for processing confocal data from a Leica CLSM. 
I have heard of several groups that have built convertrs for Bio-Rad confocal
data to AVS, but I don't know who off hand. You may wish to direct your 
question to the confocal listserv list which has been discussing AVS of
late. The address is: confocal@ubvm.cc.buffalo.edu (this is for messages
to the list, not for subscription.)
However I can tell you that there is a general purpose Bio-Rad file reader
and converter (to formats readable with READ_ANY_IMAGE in the IAC ftp
site) available as part of the Net-PBM-plus package. This is available by ftp
from: ikaros.fysik4.kth.se in dir /pub/pbmplus. This routine will sput out
individual images, which can be collected together with I belive the 
"glue" module, also at the IAC. (I can't remember, I renamed it when I 
compiled it here). Alternately, you could spit the images out as raw,
and cat them together into one big scalar byte field. 

Alternately, there is a routine that was written for the NIH image
program on the mac available as a binhex document from Barney.cals.wisc.edu
in pub/mac/image/IMR_MACROS

Anyway, once you have the images together in one big field, there are
a number of things you can do in AVS. My preferred
method of visualization involves the following:

read field
   |
crop (->x-ray ->image viewer to see what I'm doing)
   |
compute shade (req's colormap)
   |
tracer
   |
display tracker

Alternately, I send crop ->x-ray ->colorizer -> image viewer to get a 
feel for the noise level. If it's bad and I dont want to remove opacity
with the colormap, I use histogram stretch to segment the noise out, and 
expand the dynamic range. 
If you want to get real fancy, you could take the crop output and send 
to two branches:

            crop
         /        \
hist. stretch ip threshold
       |           |
       |        ip edge
       \          /
        ip logical   generate colormap
          |         /
        compute shade
          |
        tracer
          |
        display tracker

This network uses
Ip threshold (to make it all 0 or 255, and threshold the noise)
and then to ip edge (I use unweighted line, or gaussian, with kernel 1.4)
to pull out a surface (cell membrane, organelles, etc),
ip logical to combine the two fields with the "or" operator
and on to the tracer, using the colormap to make the surface partly 
transparent so the high intensity staining in the cells is visible within.

Using the virtual trackball of display tracker, one can rotate the 
object around for viewing from different sides. To move the lighting
in tandem with the rotations, make the display tracker output port
visible (4x4 transform) and plug it into the far left input on compute
shade. 
That's one set of networks. I am sure there are other that work quite well
for confocal data. Some users like to do isosurface on the field and run the 
output to the geometry viewer, but I have had bad luck with that as the
data from confocal tends to be too complex, and the machine bogs down doing
the isosurface and eventually runs out of memory. With ray tracing the 
memory useage is more predictable, though the output takes much more
massaging to get good looking images.

FOR IMMEDIATE RELEASE


ADVANCED VISUAL SYSTEMS ANNOUNCES AVS/EXPRESS 

 
Extensible Development Environment for Technical Applications 
Speeds Software Development 

WALTHAM, Mass., May 3, 1994 -- Advanced Visual Systems Inc. (AVS
Inc.), a leading developer of 3D visualization and software
development products for technical professionals, today announced
the availability of AVS/ExpressTM.  AVS/Express is a multi-
platform application development environment that provides
component technology to enable rapid prototyping and building of
technical applications.

AVS/Express is an extensible, standards-based software
environment optimized for developing technical applications with
interactive visualization and graphics functions.  Typical
application areas for AVS/Express include medical imaging,
geographical information systems, seismic interpretation,
engineering analysis, environmental studies, financial modeling
and telecommunications.  AVS/Express lets developers easily
prototype, build and maintain applications.  In addition, the
product's component technology enables end users, ISVs and other
developers to easily add user interfaces, graphics, imaging or
visualization features to applications.  

"AVS/Express brings technical developers the benefits that
client/server development tools brought to MIS and commercial
developers," said George Brandt, president and CEO, Advanced
Visual Systems.  "Like client/server tools, AVS/Express provides
broad-based, integrated application building features, such as
visual programming and rapid prototyping.  AVS/Express combines
these capabilities with state-of-the-art component technology for
graphics and visualization.  This combination addresses the
unique requirements of technical applications -- those which
involve very complex or large data sets, require interactivity
and incorporate graphics and visualization functions."

Visual Programming Speeds Software Development 
AVS/Express employs an object-oriented visual programming
environment, called the Network Editor, which displays an
application's structure in a flowchart-type graphic.  This chart
gives developers quick insight into the data and functional
relationships between the components, or objects, of the
application.  This simplifies development and speeds the writing
of production code by allowing users to bypass traditional linear
programming and quickly and interactively prototype applications. 
AVS/Express includes libraries of objects for user interface,
graphics, imaging and visualization functions, which can easily
be added to an application through the Network Editor, without
requiring specialized graphics programming skills.

Using traditional programming techniques, new objects can be
created by the developer and easily added to the application.  In
addition, a developer's legacy code, be it C structures and
functions, Fortran subroutines or C++ classes, can be quickly
encapsulated as components and integrated for use within the
Network Editor.  This process provides the developer with the
primary benefit of software reuse, which is the ability to
develop higher quality software more quickly.   AVS/Express also
supports leading standards for user interface, graphics libraries
and data communications, adding to its usability and protecting
developers' technology investments.

The central control in AVS/Express is the Object Manager, which
manages an application by defining data, functions and data
access, as well as scheduling and executing functions.  The
Object Manager provides the run-time environment for an
application while insulating the application from platform and
system differences.

"Our company concentrates on developing algorithms for the
medical imaging industry, and rapidly prototyping and visualizing
the algorithm results is critical to meeting our customers'
requirements," said Johan Brag, president and CEO, Focus
Graphics.  "AVS/Express enables us to accomplish this goal. 
Additionally, by encapsulating our algorithms as AVS/Express
components, we are able to leverage the application development
environment and deliver our technology across a wide range of
platforms and operating systems.  AVS/Express has dramatically
simplified our cross-platform development process."

Kits Provide Tested, Extensible Components   
AVS/Express also includes a Data Visualization Kit, an Image Kit
and a Graphics Display Kit.  These kits contain complete suites
of objects for data visualization and analysis, image processing
and data display, all of which are flexible and reconfigurable,
and can be incorporated into an AVS/Express application through
the Network Editor.  The Graphics Display Kit allows users to
display, render and manipulate text, images, 2D and 3D geometries
and volumes.  It is also optimized for the types of data most
frequently found in data- and graphics-intensive applications. 
The Graphics Display Kit is designed for maximum efficiency when
paired with a wide variety of graphics hardware adapters. 
Specialized graphics hardware is not required to take advantage
of AVS/Express.  As a state-of-the-art software renderer, it
provides superior rendering capabilities, even on standard
workstations and PCs.    

The Data Visualization Kit contains a broad suite of functions
for the visualization and analysis of technical data types,
including image, volume, finite element, scattered and geometric
data.  The Image Kit provides more than 65 high-level image
processing functions.  The functions in the Data Visualization
and Image Kits are based on the same proven technology found in
AVS Inc.'s Application Visualization System (AVS), which has been
a standard for visualization since 1988. 

A User Interface Kit is also included in AVS/Express for complete
Graphical User Interface (GUI) builder capabilities.  This kit
provides the developer with the components necessary to specify
the construction and layout of an application's user interface in
both native Motif and Windows environments.  Applications
developed with the kit are portable across UNIX workstations and
Windows-based PCs.  Because the User Interface kit is tightly
integrated with the Network Editor, application development is
streamlined by the elimination of the edit-compile-link process
found in traditional GUI builders.  

Pricing and Availability
AVS/Express will be available in the second quarter of 1994 for
all major UNIX workstations, including Sun, Hewlett-Packard, IBM,
Silicon Graphics and Digital Alpha running OSF/1.  Pricing for
AVS/Express developer packages begins at $18,000, with subsequent
seats priced from $4,500.  AVS/Express for Windows NT on Digital
Alpha and Intel-based PCs will be available later this year.  

Advanced Visual Systems Inc., headquartered in Waltham, Mass., is
a leader in the development and delivery of visualization and
software development products for technical professionals and
application developers.  AVS, the company's flagship product, has
emerged as the industry-standard, platform-independent 3D
visualization application software and development environment,
with thousands of users worldwide.  AVS also sells and supports
the Uniras product line, which since 1980 has provided visual
data analysis and presentation graphics software for scientists,
engineers and programmers. Advanced Visual Systems provides
visualization and software development solutions on more than 20
computing platforms from supercomputers to workstations to PCs.

I have developed a set of networks for a researcher.  I have tried to give
the networks descriptive names, however, a picture is worth a thousand words.

I am looking for a UNIX based program to create a contact sheet of rendered
images.  I would like to generate an image which contains 'thumbnail' images
of my networks.  The researcher can then look at the contact sheet and choose
a network that does what he wants.

If enough interest is generated, I will post a summary of programs and ftp

Thank you,

I'm having terrible difficulty in writing a module which makes use of
an upstream transform connection to the geometry viewer, and I wonder
if somebody knowledgable/ experienced could help. 

I'm trying to write a module which slices a geometry (actually a
ball-and-stick representation of a crystal structure) by a plane
and want to allow the plane to be moved either by controls on the
panel or by transofrming it within the geometry viewier.  My prototype
attempts aren't meeting with a lot of success, mainly because I don't
understand the basic design strategy.  This in turn is because I don't
know exactly how the geometry viewer handles upstream transform data -
it isn't documented anywhere that I can find.

Basically what I am doing is

a) generatying my crystal structure geometry 
b) generating the slice plane in a standard orientation
c) Adding them to a single edit list (ie I have 1 output port)
d) Calling GEOMedit_set_matrix() & GEOMedit_set_position() and
   GEOMedit_center() on the plane object to rotate and move it to the
   specified position.  The rotation etc is determined from the
   controls, ie the values of the AVS parameters.
e) I set the transform mode to "notify".

If I get an transform event I

f) Calculate the parameter values corresponding to the received
   transform matrix.
g) Set the controls using AVSmodify_parameter()
h) Go to (a)

That is, I am *replacing* the existing geometries on each invocation,
and on each upstream transform event I recalculate the parameter
values, (resetting the AVS parameters at the same time) and generate
the new slice plane (and resulting crystal geometry) from these values.

The trouble is that the geom viewer seems always to flag a
transformation at this point and worse, it returns the matrix of the
PREVIOUS incarnation of the plane, not the one I just set.  Can this
be due to my replacing the geometry and setting the matrix in a single
function?  In any case, it leads to a looping network with the plane
flipping between two positions/rotations.

Now I can kludge the code to ignore the first upstream transform
invocation but this isn't satisfactory as it leaves no way of making
the "redirect" mode work - which I want to do.  Furthermore, the
geometry viewer doesn't seem to be consistent (ie I can't identify the
systematics - I'm sure it's really deterministic) about when it
generates upstream transform events.  For example it SOMETIMES sends
one when I transform the "top" object and sometimes doesn't!

And is this model a good one in any case?  It kind of assumes serial
and alternating execution of my module and the geometry viewer.  That
can't be right since the geometry viewer can act asynchronously, eg
an object in constant motion.  How do others handle this?  Should I be
using a second output port for the slice plane geometry?

What I am really looking for is some guidance about the correct
paradigm for doing this kind of thing, rather than code, but some
examples would be nice too!

Thanks

Is the following a known bug in the "contrast" module???

The doc for this module states that input data values between the input min
& max are transformed according to the equation "new_value = ...". 
Further, it says that input values OUTSIDE the input min & max are clamped
to the output min & max.  However, this clamping is NOT done on a GS-2000
or a DEC Alpha (OSF/1 version).  Instead the transform that is REALLY done
is simply the line defined by the "new_value" equation extended over the
domain of the input data.  Our usual MO is to follow the contrast module
with the "display image"; we never saw the error since the lookup table in
essence does the clamping.

Any comments?  This seems like a big bug!  (Sorry if this has been
discussed before.)  I bet it is happening on other machines, too.  Is there
a correctly working contrast module out there?  Is there a bug fix for
this?  (I really like AVS, but this kind of thing drives me crazy!)

Hello all,
	First off, thanks to all who helped me with read field.  I
meant to reply thanks but deleted my mail one day by accident.  
But now more questions. Sorry, but there doesn't seem to another 
site using AVS around this .edu. 
	I'm read fielding (gr?) rectilinear field data that looks like this
.fld ======>

	# AVS field file
	#
	ndim = 3
	dim1 = 6
	dim2 = 6
	dim3 = 6
	nspace = 3
	veclen = 1
	data = double
	field = rectilinear
	coord 1 file=Tfield.crd filetype=ascii skip=0 stride=1
	coord 2 file=Tfield.crd filetype=ascii skip=1 stride=1
	coord 3 file=Tfield.crd filetype=ascii skip=2 stride=1
	variable 1 file=Tfield.dat filetype=binary skip=0 stride=1

Don't ask why the coord files are ascii, haven't figured out how to 
make them work as binary.  Anyway the data seems to be read in correctly,
checked out with 'write data' and 'print data' mods.  I'm pretty new at
this so I'm using the network editor right now.  Unfortunaly, with
this data I don't get any pictures with any .net(s) I've tried.  These
are the standard example nets given in the manual.  The rendering mods are
disp. pixmap or render geom. if I rememeber correctly.  The question is,
does anyone got any small .net files which will render this data or any
idea why these standard .nets ain't showing noth'n. 

BTW the display opens and color legend will display the correct range.


Any help would be very much appreciated.

it works in a subroutine, but in a coroutine with the same code I get
the following Runtime ERROR:

The data accessing works and the data are correct available at the outputport.

Can anybody give me a hint?

Is anyone aware of any home-grown graph viewers that are better than
the standard AVS viewer?  I checked the ftp site, but couldn't find
any.  All advice/pointers are appreciated.

Apologies if this is an FAQ. Are there any molecular biology related
modules or networks out there. A colleague here at the USGS does
16SrRNA sequencing and probe design and we're wondering if there're
any AVS tools the would be useful in the visualization of such things
as secondary structures. Any suggestions, ideas? Thanks.

Use the standard "write image" module, which writes in the AVS image format,
with a ".x" suffix on the filename. This format is described in the manual,
but is simple enough to post here:

First  4 bytes, X-dimension of image.
Second 4 bytes, Y-dimension of image.

Then, Xdim*Ydim sets of 4-byte pixels. Each pixel is in the order of
one byte called alpha (numerous uses in blending, or other), one byte for 
red, one byte for green, one byte for blue.

The 4th byte, although sometimes useless, preserves 32-bit word alignment for
the pixels, which is on some computers the length of integer data types.

Howdy AVSers,
Some time ago Richard P. Signell (rsignell@crusty.er.usgs.gov)
put out a call for benchmarks of AVS rendering, suggesting the use of several
fairly standardizable tests. In the process of evaluating demo hardware here 
at UCLA, Dr. Phoebe Stewart and I ran these tests on a Sun and some DEC 
machines with various Kubota graphics options. As these results may be useful 
to others in this field, I am posting them here. All tests were with the 
latest version of AVS (5.1) on otherwise unloaded systems. The Dec machines
ran DEC OSF/1 V1.3 Rev. 111, the Sun ran SunOS 4.1.3 (most patches installed).
All machines had at least 128Mb swap space allocated.

Workstation comparisons.

Machine M1: Dec Alpha 600 Kubota 620 graphics		128 MBytes RAM
Machine M2: Dec Alpha 600 Kubota 510 graphics		128 MBytes RAM
Machine M3: Dec Alpha 600 Dec ZLX-E1 2D-graphics	64 MBytes RAM
Machine M4: Dec Alpha 600 Dec HX 2D-graphics		128 MBytes RAM
Machine M5: Dec Alpha 500 Kubota 620 graphics		128 MBytes RAM
Machine M6: Dec Alpha 500 Dec HX 2D-graphics		128 MBytes RAM
Machine M7: Sun Sparc 10-41 GS graphics			64 MBytes RAM

Notes: Dec ZLX-E1 and Dec HX are software rendering(?). All other
timings are with hardware rendering on (Geom, cameras menu).

(from rsignell@crusty.er.usgs.gov)
THE TESTS ================================================
 
Test 1: Teapot. Invoke avs with "avs -timer".  
Bring up the geometry viewer.
Load the "teapot.geom" object from the /usr/avs/data/geometry directory.  
Leave window at default size.  Start it spinning.  Stop it.
In the window you invoked AVS, you will see the number of
frames per second (FPS) that your machine produced, and gives
you a solid number on 3D graphics performance to compare with 
other machines running AVS.
 
Test 2: Mandrill on Teapot.  In the geometry viewer, click on 
"edit texture", then select the "mandrill.x" image from the 
/usr/avs/data/image directory.  Click on "set dynamic texture".
(on machines without hardware texture mapping, you will need to 
change the "camera" setting from "hardware renderer" to "software renderer".
Start it spinning. Stop it.  The FPS this time gives you a solid number
of how well your machine does on 3D graphics performance with 
texture mapping. If your machine has a "Filter Texture" option, 
use "Point" (no filtering).
 
Test 3: Carib.  
Same as Test 1,  but with carib.geom.  Normalize carib.geom
so that it fills the default window.  Spin about the E-W axis.
This is a better test for high-end machines that are maxed out at 
the screen refresh rate with teapot.geom. 
 
Test 4: Mandrill on Carib.  
Same as Test 2,  but with carib.geom.  Normalize carib.geom
so that it fills the default window.  Might have to
tile mandrill if it doesn't cover the carib geom.
Spin about the E-W axis.  If your machine has a "Filter Texture" option, 
use "Point" (no filtering).
 
Test 5: Spheres.
Same as Test 1, but with /usr/avs/data/geometry/molecules/lysozyme.geom
This is to test spheres, and some machines do this in hardware.
Set "Subdivision" in the Geometry Viewer to 4 (this is irrelevent
on the machines with hardware sphere rendering).

=====================================================
TESTS:

Test T1: Spin teapot.geom
Test T2: Spin teapot.geom with mandrill.x textured mapped
Test T3: Spin Carib.geom
Test T4: Spin Carib.geom with mandrill.x textured mapped
Test T5: Spin normalized lysozyme.geom (subdivision 4)
-------------------------------------------------------
Our own tests:
Test T6: Calculate isosurface and display adenovirus averaged down by 2
Test T7: Spin adenovirus averaged down by 2
Test T8: Calculate isosurface and display full scale adenovirus
Test T9: Spin full adenovirus
-------------------------------------------------------

         M1	M2	M3	M4	M5	M6	M7
T1 (fps) 72	72	1.9	4	72	3	5.8
T2 (fps) 18	18	1.1	2.5	18	2	NF

T4 (fps) 4	3.4	0.2	0.7	4	0.6	NF
T5 (fps) 18	14	0.8	2.8	18	2.2	1.1

T7 (fps) 1.5	1.2		0.11	1.5	0.09	0.1
T8 (sec) ~205	~215			~366		NF
T9 (fps) 0.35	0.29			0.35		NF

Notes: 
Several tests produced rates of 72fps, which is the refresh rate
of the monitor, thus not compute performance.

NF = non-functional

fps = frames per second

sec = seconds. Tests 6, 8 were "wall clock" (wristwatch) times, 
not generated by the computer. All other times were generated by AVS -timer.

I have an AVS model of the structure of a large radio telescope which
is being built in a valley in Pocahontas County, West Virginia. It
occurred to me that it would be nice if I could make the valley and
surrounding hills appear in the backgrounds of the AVS scenes, instead
of using the "grid" module to put a flat piece of symbolic ground
under the model. What sources of terrain data are available, at what
resolutions and at what prices? I would consider 1-200m horizontal
resolution and 10-20m vertical resolution over an area 10-20km square
to be quite nice, and I hope that such data are in the public domain!
If you are curious about my application, open your Mosaic tool on the

Sigh... there is a problem. The Khoros subdirectory at IAC is now
empty.  File avs_modules/KHOROS_README says:

"The International AVS Center is no longer a member of the Khoros
Consortium.  Therefore we do not have the rights to distribute the
Khoros source code.. the University of Manchester has picked up this
distribution.  Their location is
        ftp.mcc.ac.uk(130.88.203.12):/pub/cgu/avs/avs_modules/KHOROS"

This URL is not valid. I have searched the Manchester FTP archive, and
do not find Khoros code.

Is source for the AVS module "remote_gis" still available somewhere?

I'm trying to get the Create_MPEG module from the IAC to work on
an SGI workstation running IRIX 4.0.* without any success.  I can
compile the module without any problem.  However, the module always
dies whenever anything is done with any of the widgets and the module
starts running.  If I enter a file name to write the mpeg file to,
it dies.  If I toggle 'pause' it dies.  Also when I have it connected
to prepare video to do gamma correction, I get a message about a problem
with the direct data transfer between prepare video and create_mpeg.

Any suggestions?

Check out the 3 arc second digital elevation models at:

http://info.er.usgs.gov/data/cartographic/index.html

To find out if the USGS have more detailed DEMs for your region
you can call the standard USGS phone number for mapping info:

1-800-USA-MAPS

Once you've got the terrain data, you can use the "remote_gis"
module in the khoros directory at the IAC to read them into AVS.

Sorry, no real insight to lend.  
(I have picked up the module and run it on a HP successfully though.)

Did you pick and build "mpeg"?  (From your description, it doesn't
sound like the subroutine is getting that far, but ...).

It's all my fault!! sorry. I wrote the module an awful long time ago
and it was about the 5th module I had written and so there were a few
mistakes in it. I have sent off version 1.1 to AVS which works on an SG
I have been told. It was all to do with not declaring enough memory and
then running over the edge of an array(s) it should be all fixed now.

Sorry
	Alex.

Typically USGS data is the easiest to obtain... Call 1800 USA MAPS for more 
info. I just finished a piece using a 32 x 32 mile area (a total of 6.7 
polygons). As for price and detail info, you'll have to ask.

I think what you can use is the "isosurface" module.
Input: 3D scalar field (= sequence of 2D images)
Output: geometry

Hope this helps (?)

I am trying to translate one object within a hierarchy of several
objects.  Since the objects have their own coordinate system, I need
to move the objects to get a accurate total representation.

When I try to translate one object, the entire picture is moved instead
of one object.  I select one object to be the current object.  I then
select transform object and make changes to the translation portion.

Does anyone know what I am doing wrong?  How do I translate one object
without affected the other objects?

Thanks,

I would be very grateful for advice on how to achieve the following. I am
using the field-to-globe module to map scalar image data around the surface
of a sphere. Is it possible to also display a colour legend showing the
values of the data or better still enable to click at a point on the sphere
and be told the value of the scalar at that point.

Many thanks in advance.

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

  IBM Scientific & Technical Systems and Solutions (STSS) is pleased
  to announce the availability of the library DX/Runtime
  extending the IBM Visualization Data Explorer (DX/6000) for run time
  visualization of data. This library DX/Runtime has been developed 
  at the STSS International Center HDSTC in Heidelberg (Germany).

  This package addresses the needs of IBM customers to visualize their
  data generated by a simulation during run time (on line).
  HDSTC will distribute the software and provide maintenance to customers.


  MAIN FEATURES

  DX/Runtime consists of two parts:

  - DX/Runtime modules that allow the user applications to be started 
   dynamically from the Data Explorer/6000.

  - DX/Runtime modules for the communication with these applications
   (using the sockets interface).

  One of the key features of DX/Runtime is its ease to use, e.g. 
  the standard GUI of the IBM Visualization Data Explorer may be
  applied for programming the run time visualization. 


  PRICING CONDITIONS 

  Below are reported the prices of DX/Runtime (inclusive 
  of one year maintenance). All prices are in U.S. dollar per node.

HI-

I'm looking for a way to take all of the slices in a 3D data set and
add them to another image (I want to generate a 2D image, not another
3D data set).  I can do this manually, by using ip arithmatic saving
the result, reloading it and adding thenext slice, but this seems
awkward at best.  Does anybody know of a better way to do this?

Thanks,
Chris Tully

If you can represent them as a 3D uniform field, you can pass them into
the X-Ray module, which lets you sum slices along any axis, as a volume
rendering technique. It will only work on scalar (1-vector) fields though.
If you want to use color images or other non-scalar fields, I wrote a 
module to do the same thing but with n-vectors. Lemme know if you want it.

I am trying to write a program to display a mesh of a finite element(FE)
model. I am using the connectivity data to draw lines to connect nodes
and get a mesh. Quite easy. But one problem comes up:

Since an edge would appear multiple of times if it is shared by
more than one element, I would like to avoid plot such edges multiple of
times. My question is:

Is there an efficient method to avoid drawing edges multiple of times?

Any help would be mech appreciated. Thanks in advance.

You could do this by isolating the edges (sides) of the elements.
Then you could just plot each of the edges. However, this will take
a bit of cpu time, but not too much.  However, I plot my meshes
by drawing each triangle and so interior edges will be drawn twice.
But this is no problem and it doesn't take much cpu time either.
If you decide to store the edges, I can show you how.

I believe the Indigo2 Extreme is in the $40k-$50k price range and is
a pretty decent machine. The next step up would come close to $100k. 
I don't know what is SGI's educational discount schedule.

Hi Sally,
  There are ways to do this programmatically with the geom api's. From the
geometry user interface the way to do it is :

                1.) select the child object you wish to translate
                2.) above the "Transform Object" you see the
"Transform Selection" dimple, select it.
                3.) A "Transformation Options" panel appears, at the
                   bottom of this panel , choose the "Override" button

Now you can manipulate the child object without affect the rest of the objects.

An easy way to avoid plotting element edges more than once is to pack
both end nodes into a single word and use a simple sorting algorithm.

1. For each straight element edge pack the two nodes N1 and N2 into 
   LIST(II) = 32767*N1+N2 where N1 is the lowest numbered node. 

2. Sort your LIST in ascending or descending order. Duplicate edges
   now follow each other.

3. Unpack and plot only the first of each edge.

This scheme will only work with 32 bit words, no node numbers > 32767
and no higher order edges. It is however very fast and simple.

Does anybody have any more general algorithms ?

                                         ^^^^^^^^^^^^^^^^^^^^^^

Sorting carries unnecessary overhead. Since you're compiling a list of
edge info, why not just put it in a hash table where you construct the
hash key using the two node numbers? Edges which overflow their table
entry can be rejected (as these are duplicates) and those which remain
can be rendered/plotted; no sorting necessary.

Hello,

I am working with a fellow who is doing research in the area of
smoothed particle hydrodynamics.  The "particles" in his case are
3D ellipsoids.  Does anyone know of any module that would, given
a list of points in 3-space, create 3D ellipsoid geometries?

Does anyone know of an efficient way to create these geometries? 

Thanks in advance,

   -Tim

Does anyone know how to feed .hdf files into AVS? Are there any
special modules for converting .hdf files into avs format? If not, is
it possible to transform .hdf back into ascii numbers so that one
could later read them as an ascii field? 

I would appreciate if someone could post the answer or send me  
an e-mail at rozas@wpi.wpi.edu.

Thank you 

David Rozas
