			Solicitation!!

Many of you may be familiar with the Graphics Gems
series of publications.  They are basically collections
of source code that individuals are willing to share with
one another.  Many programmers have interesting jewels
of code they have developed to do their job better, faster,
or more accurately.

The International AVS Center has decided to do a similar
publication thanks to the suggestion of Dr. Marc Kessler.
We are going to solicit modules along with a page or two
of documentation and publish a book of the best of these
contributions.

So, if you have a module that you would like published
that would be useful to the AVS community, send your
code and article to the International AVS Center, 
3021 Cornwallis Road, RTP, NC 27713 or email to
avs@ncsc.org to be considered for publication.  Modules
will also be placed on the public domain site for sharing
unless otherwise specified.  Every category of module
will be considered for publication.  Thank you.

Mwm*client*background: MidnightBlue

Some users of AVS 4.0 on RS/6000 with AIX 3.2 have encountered a
peculiar problem in which a warning message about reduced colour usage
is encountered upon starting up AVS (on a workstation that gives other
users full colour support).

I have traced the problem to the following line in the .Xdefaults file of
those affected:

Mwm*client*background: MidnightBlue 

Correcting the line so that it reads:

Mwm*client*background: MidnightBlue

makes the problem go away.  See the difference?!  There is a space
at the end of the first line.

Is it normal for AVS to handle an incorrectly specified colour in this way?
Other applications don't show this peculiarity, or at least don't announce it.

Hi,

this module is obsolete...there is a module called "luminance" which
does the same thing, and is shipped with avs.

unless you're after the source code, you don't need this module.

Hello All,
I have an AVS/Khoros question. I am attempting to compile an AVS 
module for edge detection which utilizes the khoros library routines.
I do not have the trillion meg of disk space to install the library. 
The module calls three routines which I assume are in the khoros 
distribution. They are expfilter(), gradadp(), and threshold(). Is it 
possible to just extract these routines from the khoros distribution??
I have loked at an Index for khoros and didn't see them. Am I doing 
something wrong? If anybody knows where the source for these routines 
are located could you please drop me a line. My address is 
	holupka@snips.dfci.harvard.edu
Thanks in advance.

Please note that these modules are currently in what software companies
might call a "beta," or maybe even alpha phase.  The Image Processing
and Digital Signal Processing algorithms, have been thoroughly tested
through 5 levels of release by the khoros group, however, the avs 
wrappers which now call these algorithms have not be thoroughly debugged.
For an experienced C/AVS programmer, fixing one of these modules is
relatively straight forward; otherwise the maze of code is a mess.
Please forward us all bug reports in any case so that we can update
the archives with improved "bug-free" versions -)!

> I do not have the trillion meg of disk space to install the library. 

The entire AVS/khoros distribution requires 128 Mb including source,
libraries,includes, and binaries for multiple platforms.  This is
primarily a function of the vastness of the khoros code, rather
the avs implementation.

> The module calls three routines which I assume are in the khoros

expfilter is referenced in libvmath.a
gradadp   is referenced in libvmath.a
threshold is referenced in libvmath.a   ( all determined by nm'ing .a's )

Thus I would reccomend downloading the appropriate khoros library
set for your platform, and erasing all but libvmath.a .

Khoros is available to non-profit, academic institutions through anonymous
ftp to pprg.eece.unm.edu, if you don't have disk space.... beware !

Good luck-

We are currently considering the purchase of a "supermini".  One of
the primary uses of the machine will be as an AVS server in a
distributed environment.  We are currently considering a Convex C3220
with 512 Mbytes of memory and a Cray YMP-EL also with 512 Mbytes of
memory.  Display will be done over the network on Stardent GS series
machines or IBM powerstations.  I would appreciate getting feedback
from people that are using either of these machines in a distributed
environment for visualization.  I would especially like to know about
performance, pitfalls, etc.  We use AVS mostly for display of data
generated by finite difference and finite element codes.
Please reply via email.   Thanks in advance.

I have some questions.

I want to animate the Gaussian density function:




           2         2     2         2
         -x /(2 sigma ) - y /(2 sigma )
        E

                            2
                  2 Pi sigma


for differnt values of sigma.
I didn't find any AVS-routines for reading functions (if there is let me know),
so I made a plot in Mathematica
            saved it in ThreeScript-format
            used the geometry filter ts_to_geom
            and imported it into AVS.

I repeated this for each step of sigma.

And at last made an animation with the display-pixmap module.
The Geometry Action command doesn't work for this ?

Is there an easier way for doing this ?

I also am interested in using the LUI library. The IAC module Edit_String
gives an example of a large text write-in window which I would like to use in
an application. I'd like to modify it, but I don't know what the LUI calls do.
Apparently there is LUI documentation available to some people, since they are
writting modules with LUI calls. But I can't find anything in my manuals (from
Kubota.)

AVS, Kubota: any help?

If I understand your problem correctly, you have several options 
available to you:

1) Write an AVS module which creates a "field 2D uniform scalar float"
where the X and Y indicies of the 2D field are the x's and y's in your
equation above.  See the "read image" module in the /usr/avs/examples
directory for a starting place.  The output from this module can then
be fed into the "field to mesh" module to create a 3D surface. 

2) Animating the surface:  presumably your module will have sigma as
a parameter, so that you can either vary it by hand or drive it 
automatically.  One way to do this is to hook up the ANIMATED FLOAT
module to sigma.

3) Your module could be written as a 'co-routine' module which runs
asynchronously and drives itself (as opposed to option 2 above)

4) You should be able to do what you have described above - using 
Mathematica and then dumping the results into AVS and storing up the 
geoms in the Geometry Viewer 'Action' menu.  There is a module at the 
International AVS Center (avs@ncsc.org) written by the Mathematica
folks which should facilitate this.  If you don't get this working,
try your customer support group.

Do these alternatives give you encouragement to try again?  I hope
so.  Let us know how you make out.

Hi netters, dear guys from AVS,

   I am currently trying to visualize results from FE-computations. To import the results into AVS I am using the ucd structure. The cells are quadriliteral with midedge nodes on every side.(BTW the idea to use only a subset of the midegde nodes is, as I know, not very common. So I would suggest to introduce additional cell types which are just the basic types with all midedge nodes.) 
  In the documentation it is stated that by setting the appropriate midedge-flags, edges with midnodes can be stored. I tried this but none of the modules accepting ucd's gave other results |-(. 

 >>> So are there any modules taking account of defined midedge points ???

Is there anybody who has experiance with ucd's using midedge points ??

Any help would be appreciated !

Thanks in advance 

Georg

the generic avs ucd modules have many shortcomings. if you have access to
a convex and it has avs then i would recommend trying the convexavs3.9
module ucd_make_geom.

Does anyone have experience with the Animation package in AVS 4.0 ?
I have been using it for a couple of days, and it does not do what
it shoudl. for example:

	1. I manipulate the camera in the gemoetry viewer, saving
		keyframes as I choose diferent views, all the while
		making sure that each view is less than 180 degrees
		of rotational transformation from the previous one.

	2. When I step through the recorded keyframes, the view is
		COMPLETELY different than what I saved. 

What gives?

The IAC's field_2Dto_3D should do it:

NAME
	Field 2D to 3D - converts a field 2D to a field 3D

SUMMARY
	Name	Field 2D to 3D
	Type	Filter
	Inputs	In 2D Field - 	field 2D REQUIRED

	Outputs	Out Field - 	field 3D

	Parameters
	Name		Type	Default	Choices	NONE

DESCRIPTION
	Field 2D to 3D converts its input field from 2 to 3 dimensions,
	and sets the physical-space dimensions to 3-space.  The data
	remains unchanged.  This module is useful, for example, if you
	have a 3-vector 2D field that you would like to view with Hedgehog,
	which requires field 3D uniform data.

INPUTS
	In 2D Field - field 2D
		The field 2D that needs conversion

OUTPUTS
	Out Field - field 3D
		A field identical to the input field with the array and
		physical dimensionality increased to 3.  The data and
		coordinates remain unchanged.

EXAMPLE NETWORK
	This example reads a field 2D and converts it to a field 3D that
	Hedgehog can use, then displays it.

> hi,

dfft1d is a khoros module which performs a 1D Fourier transform on a set
of data sequences.

the name of the module comes directly off of the khoros glyph.

the avs port of this module is in ~ftp/avs_modules/khoros/transform1D
on the iac ftp site.  transform1D is the khoros "toolbox" which dfft1D
belongs to in khoros, thus the directory.

> if that's has already been done, then where i can get the source for that

get the source and libraries from the iac, and good luck compiling...

> and how do i get the graph viewer to display the output of dfft1d.

all the khoros modules communicate through "field 2D's" modelled after
the Khoros viff data type.  Thus, you would need to use the "image 2 signal"
module which is in

~ftp/avs_modules/khoros/avskhoros_utils

before sending the 1D signal into the graph viewer...

Good luck-

Terry

Hi AVSers,

Four modules linking Mathematica with AVS have been placed on the
IAC's anonymous ftp site this morning.  Unfortunately we don't have
Mathematica here on a DEC, Sun, or Kubota platform - the ones
the modules had already been ported to.  But rather than keep the code
to ourselves, we've placed it out there for everyone to use, although
they haven't been tested here yet.

Also - the field2_from_Math module's author was incorrectly listed
when it was initially placed on the site.  The *correct* catalog
postings are:

Description : This module is a first shot at incorporating QuickTime(tm)

              high quality video segments. QuickTime(tm) is rather
              convenient since there is likely to be more support on other
              systems, and there is a growing base of QuickTime(tm)
              cheaply available for the Macintosh. This code currently
              requires, the QuickTime Movie Exchange Toolkit, which is
              available from Apple, Inc, and a C++ compiler (you also need
              the C++ compiler to build the QuickTime(tm) libraries.
              Please note - since the IAC doesn't have the Exchange
              Toolkit, we weren't able to test this module out here.

 Hallo,
 
 There is a person to tell me if there is a AVS module that is able to 
 recognize geometric pictures from a AVS file 2D (.x) ?
 Otherwise which kind of network is necessary to build to obtaine this
 result ?

 For example : If I have an image with Olympic logo there is a module
 to tell me that in my picture there are five circles linked together ?

                              Thank You

Hedgehog has a number of limitations, such as not being able to
conveniently place arrows at the exact positions of the original data
(even if it is uniform).  There also seem to be an unfortunate lower
limit on the vector scale.

Therefore, when recently faced with the problem of displaying 2-D vector
fields myself, I found the 'node' option in ucd hog module more appropriate. 
This draws arrows at the position of the input data points.
I have a short FORTRAN program to convert an irregular 2-D field of 
2-D vector components into an ASCII ucd file (using point elements
with a 3-D vector at each point).  It is not packaged for public
consumption, but I will mail it to anyone who wants it.

I was not completely satisfied with the result from ucd hog, in that
it could produce colour-coded arrows of a constant length, or white
arrows with a length proportional to the vector magnitude, but not
coloured arrows with a length proportional to the vector magnitude.

A useful addition to AVS would be hedgehog or ucd hog-like modules
(that is, modules that provide 'glyphs', such as arrows, at an 
arbitrary set of input data points) that provide for more flexibility:

 - provide direct support for 2-D fields
 - provide direct support for rectilinear, curvilinear and scatter data
 - accept an input vector field to provide direction information
 - accept an input scalar field to provide scaling information (not
   necessarily proportional to the magnitude of the vector field).
 - colour the glyph according to yet another field.

the file browser string comes in as a char *browser

the output port needs to go out as a char **output

You don't need to allocate any memory at all since it has already 
been allocated by the input port.  You only need to point to it. 
Here is an example (lifted from the 'file browser' module source).

I have a nice little AVS animation which generates a bunch 
of 24 bit images, and I'd like to stuff these into a 8-bit
HDF file so that colleagues without AVS and 24-bit displays
could look at the animation with NCSA's ximage or xdataslice.

The problem: 
>From the 24-bit animation images, I need corresponding
8-bit animation images and a single 8-bit colormap.

One approach, which seems a bit brute force, is to save each
AVS image in a separate file, convert one of the frames to 8-bit 
using the PBM+ tool  

"ppmquant 256 avs.image.001 > cmap", 

then use that frame as a colormap for all the other frames

"ppmquant -map cmap avs.image.001 > ppm.image.001"

then finally convert the ppm images to hdf.

This all seems pretty crude.  I'm wondering if someone has a 
better idea?

If you got higher dimensions in i or j than in k, and you toggle from either i or j to k with a slice number higher than k's dimension then the module hangs. 

I put this "if statement" into the compute module and it seems to fix it.

/* if made it here, then we're actually going to copy a slice
   over. start off by copying the data itself */

if (slice_number >= inf->dimensions[choice_value]-1)
{
   slice_number = inf->dimensions[choice_value]-1;
   AVSmodify_parameter("Slice number",AVS_VALUE,slice_number,NULL,NULL);
}

			ATTENTION AVS USERS!!!


	The International AVS Center needs your assistance.
At the previous conference and through other forums we have
received many offers from you to assist should the need arise.

	Guess what?  The need has arisen!!  We need your help.

	We have just finished negotiating for next years 2nd
Annual International AVS Users Group Conference to be held
at the WALT DISNEY WORLD Dolphin Hotel in Lake Buena Vista,
Florida on May 24-26, 1993.  Now we are beginning the search
for people to help give lectures, develop workshops, develop
tutorials, host panels, and we also need two chairs for two
of our tracks.  In addition, we are collecting videos of 
AVS user work completed in AVS and slides and posters of
work done in AVS.

	All topics are considered.  There are four discipline specific
tracks, one that is a mix of topics that do not have enough
material for a complete track, and a howto and tips and tricks
track.  Topics should lean strongly towards intermediate and
advanced rather than beginner focus.  We encourage innovations
and new and creative ways of presenting your topics.  There are
still openings in each area.

	There is some compensation available dependent upon the
areas you volunteer to assist with at the conference.  Email or 
call for additional information.

	Current topics where assistance is needed include, but are
not limited to:

	Computational Chemistry
	Computational Fluid Dynamics
	Education and Research
	Earth Sciences
	Image Synthesis and Analysis
	Medical Imaging
	Oil and Gas Exploration
	GIS and Remote Sensing
	Structural Analysis
	Scientific Visualization


	Please contact David Bennett at 919 248 1182 or via email
at avs@ncsc.org to participate.  Your response is requested by Oct 25, 1992,
or as soon as possible prior to Nov 2, 1992.

We need your name, address, affiliation, Title of your lecture.  Abstract
is not required until January 30, 1993

Hi.

I'm currently writing a module that creates a geometric object
and allows the user to move and rotate the object via an external
interface device (the Logitech 3D mouse).  My problem is that there
does not seem to be any easy way to rotate the object via the
Geometry routines --- the only routine that looked hopeful was the
one that allows the user to change the transformation matrix.  

Is there an easier way?  I'd hate to get bogged down in low-level
details of the transformation matrix.

Thanks.

-Salim

Ion,

I have had the privilege of working with Waterloo Maple Software for
some time, and have had quite a bit of experience with Maple and AVS.

Maple has written an AVS module and a Maple library in support of AVS.
The module, when dragged onto the workspace, launches a Maple session,
and reading in the library from within the Maple session

	> readlib(avs);

defines several special Maple functions.  The most essential of these
functions is AVSsend() which exports a Maple array as an AVS field.
(The MapleAVS module has a field output port.)  Other Maple functions 
exist for setting and reading the dials and buttons (four continuous
and two one-shot) defined by the MapleAVS module, and for exporting
Maple Plot3D structures (as fields) suitable for rendering via field_to_mesh
and the geometry viewer (very spiffy looking!!)

AVSsend() is defined in such a way that you can send to AVS both uniform 
and irregular fields. 

Caveats:

The module has been ported only to DEC-MIPS architectures (for now),
but many other platforms are planned -- cast your vote!  When Maple V
release 2 comes out, the module will be available for the SparcStation.

The MapleAVS module exports only float fields.

Depending on your machine, sending large arrays (which Maple stores
internally in an unpredictable arrangement) can be slow (on the order
of a minute of CPU time for a 100 x 130 irregular field)

I invite readers of this newsgroup to mail any other questions about
Maple and AVS directly to me.  If I don't know the answer, I know somebody
who does.  I will summarize all such correspondence to this newsgroup.

are seriously considering prechasing AVS for our RS/6000 (a 550e with 160

format of the vendor. Our problem is how to best convert the ACR-NEMA format  
as well as the others into a format that AVS can read and display.  Any

can be obtained, or other modules that might be of use use in medical imaging

There are serious problems with the GT4X card.  The problems don't seem
to be AVS specific, and IBM has been very slow about responding
to the problems.  IBM finally sent us a new card and new
microcode and things are better now, but there are still
problems.  For example, you can't move a window--if you do you
see the wrong image.  Also, others have complained about their
machines hanging with the GT4X.  I wonder whether IBM is really
interested in supporting this card.  There are other problems,
for example the GT4X doesn't support texture mapping so you have
to use the software renderer anyway if you want to texture map.

I've been in the middle of other GT4x users and AVS lately, and
uncovered some facts.  The GT4x has some problems with long
triangular strips which hangs the Xserver.  Some AVS demos and
applications use long tristrips (ex, Carrib + Lobster Scan demos)
which hang the Xserver.  We reported this to IBM a while ago and
"believe" IBM is working to fix this. 

BTW - We (at AVS) have a GT4x, apparently with older microcode and sw,
and are expecting patch fixes from IBM in a few days.  I'll post again
if/when I learn more GT4x info.

The connection number for any input port in AVS 4 should be zero.
Hopefully, in the future, AVS 4 will allow for multiple connections
to a single port, like the geometry/image viewer, which will allow
for this argument to be useful.

Someday, this will make it into the manual !!!

Good luck-

Bob Mazaika revealed this wisdom to me recently
at Vis '92, and it works pretty good...

On the SGI, the image viewer is an X viewer, and
the geometry viewer is a GL viewer.  The GL viewer
does not allow you to load X fonts, thus the one
size font.  The trick is to take the output from
the geometry viewer, and pipe it into the image viewer
for labelling.  Of courese this will only work for 
output labelling, and not interactive visualization.

My terminology is probably messed up, but none the
less, it works.

Good luck-

Terry

I have not applied all the AIX 3.2.3 PTF's, but I have applied many of
the fixes that are on the tape because of previous problems. Does your
xdm now complain about missing symbols?  If so, make sure you apply
X11dev fix U409264 and rebuild xdm.  Somewhere along the way libc was
changed and some exported symbols were dropped.

Hello.

I use AVS 3.0 on an HP 9000 series 700 with 32Mb of real memory 
(and 60+Mb of virtual memory) and keep on encountering a 
memory problem when allocating large AVS fields.  I know 
someone recently asked about a shared memory problem on another 
machine recently, but I believe that this is a different problem. 

Here is the code from the data allocation/computation subroutine of 
the module
=================================================================
    AVSfield_float *input;  /* define field variable*/
    AVSfield_float *vinput;
                      .
                      .
                      .
	if (*data) { 
		printf(" Freeing old scalar memory\n"); 
		AVSdata_free("field", input); 
	}
    if (*vdata) { 
		printf(" Freeing old vector memory\n"); 
		AVSdata_free("field", vinput); 
	}

	/* nxyz = number of data points  typically ~ 1E6 */
    fprintf(stderr, " about to allocate memory for (nxyz=%d)...\n", nxyz);

    input = (AVSfield_float *) AVSdata_alloc(
              "field 3D scalar rectilinear 3-space float", dim);
    vinput = (AVSfield_float *) AVSdata_alloc(
            "field 3D 3-vector rectilinear 3-space float", dim);
=================================================================

Each time I read in a new data set I free the old memory and allocate 
a new field so that I can easily manipulate data sets of different sizes
concurrently.

When running this once, it works fine.  However, if I try to read in
another data set of the same large size, it crashes with the following
messages:

======================================================================
 Freeing old scalar memory
 Freeing old vector memory
 about to allocate memory for (nxyz=916300)...
/vega/users/usadi/AVS/Modules/read_mhd: can't put field in shared memory: shmget: Not enough space
/vega/users/usadi/AVS/Modules/read_mhd: Allocation of field failed! (10999113 bytes)
 calculating coordinates...
avs: tcp_read(): Unexpected end of socket
fork failed: Not enough space
======================================================================

In other words, it doesn't seem to be freeing the old memory, at least
not before attempting to allocate new memory.  In addition, I have no
idea where the number  (10999113 bytes) is comeing from.  It should 
allocate a scalar field of ~1E6 points and a vector field of ~1E6 points.
Both are defined as float and hence, a total of 4 arrays of 1E6 points
should be allocated (~16mbytes ????).

If, after reading in a large data set, I then read in a small data set,
and then read in another large data set, it seeems to work.  In other
words, AVS seems to be out of synch with the OS in that it doesn't
immediately purge old memory.

Is there a way to force memory freeing at a certain time (i.e. before
attempting to allocate new memory?)  Has anyone encountered this
problem?  Any suggestions?  E-Mail or post.

Thanks,
Adam Usadi

I'd like to use the 'pick' functions which I think are only in AVS 4. 
Since we only have AVS 3 here, I'd like to ask a couple of questions
before I spring for AVS 4.

1. Does it really work robustly?
2. I want to put a bunch of polygons and triangle strips in the geometry, then
pick a point on one of these, and get back an ID for the entity
and the 3D coordinates on the polygon/strip where I picked. Can I do this?

Thank you
