Hello.
I'm looking for an AVS-program (AVS-module) which could calculate 
the coordinates of the barycenter of a .geom object.
If anybody can tell where I can find that kind of program, it'll be 
very very useful to me.

Thanx in advance.

This is a standard AVS demo- Van Sant's dataset
and some NASA and NOAA stuff.  AVS claims to have put the
lat/long to 3-D topo/color mapper in the public domain,
although I haven't looked for it.  They are not allowed
to release Van Sant's datasets. The FAQ in sci.geo.meterology
lists sources for some other global datasets.

I have been working with some chemistry modules and trying to write some
new readers and writers.  I have the beta test copy of the Chemistry
Developer's Kit, which ran under AVS 3.0 and contains source code examples.
None of these will compile under AVS 4.0.  It seems that the problems
are due to the different directory structure, libraries, etc. which came
about during the change from version 3.0 to 4.0.

Is the Chemistry Developer's Kit part of the standard release of AVS 4.0?  I
thought it was, but I cannot find any of the source code examples.

I am running on a Titan 3040, under TitanOS 4.2.

AVS is by Advanced Visual Systems, Inc.  Also, in my ConvexAVS manual
is the note "AVS was created and developed by, and is a trademark
of, Stardent Computer, Inc."  AVS looks like a big commercial 
package.

We have a module that creates a geometry and attempts to parent
the object to "top" using the call described in the manual:
GEOMedit_parent(*output,File_Name,NULL);
where File_Name (sic) is the name of the object we want to
parent to top, yet instead we get a new object called top.n
which is the parent of File_Name.  How do we parent the object
to the real "top."  Thanks!

I have AVS 4.1 on my VAXstation 4000/90.  Runs fine, mostly, at about the
speed of the DECstation 5000/240.  Does seem to have problems , possibly with
lack of resources (on a 64 MB machine!) - I suspect there is room for improvment
of quotas and things.  It is indeed the full release, except for the
animation module (not sure why).

They promise that AVS5 will be available same time as all other ports.
We'll see.

I am getting a little tired of having my XWindows server process lock up, though.

to use this set as an example an paper. But before that I would
like to contact the creator of the set about permission and

Could someone please provide me with a little more information

Brian left Stardent about two+ years ago.  Suggest you check the NCSA FTP

Contacts for local AVS applications developers can probably be obtained
from there.

To get the Public Domain AVS modules (over 615 of them currently!)
use anonymous ftp to avs.ncsc.org (128.109.178.23).  FYI, I will include

                        OCTOBER 1, 1992 

    
    The AVS Consortium announced the opening of the new International
AVS Center at North Carolina Supercomputing Center in Research Triangle
Park, North Carolina.  The AVS Consortium is made up of seven AVS vendors
who are funding and providing direction for the International AVS Center.
The seven vendors are Advanced Visual Systems Inc., CONVEX Computer 
Corporation, Digital Equipment Corporation, IBM, Hewlett Packard Company, 
Kubota Pacific, and Sun Microsystems.

    The full functionality of the International AVS Center became
available on January 1, 1992.  The Center was opened in several phases.
Phase I, which opened first, provides for ftp and email access to modules and
is primarily for submission and retrieval of AVS modules from the scientific
visualization community.  There over 600 hundred modules currently available 
and more will be added daily.  Construction for the porting facilities has 
been completed.  Each Consortium platform has the modules ported to it, and 
made avvailable free via anonymous ftp.  Modules are available for CONVEX, 
DEC, IBM, HP, Kubota, and Sun platforme.

        MODULE SUBMISSION CONTEST

The International AVS Center's module repository 
has been very successful in its first year.  There 
are now over 600 public domain AVS modules available 
for your scientific visualizatition use!  Thanks to 
all who have so generously shared their work!

To encourage continued submissions, and as a reward
for the modules already contributed, the IAC is
implementing a quarterly contest.  The author of the
"best" module contributed in a quarter will receive
his/her choice of $250 cash (U.S. funds), or $250 
credit towards attendance at AVS '93 ( to be held
May 24-26 in Orlando, Florida ).  Some of the criteria 
considered in a module's evaluation include the module's: 

	1)  Utility 
	2)  Uniqueness
	3)  Popularity 

These are not necessarily all inclusive or in any 
particular order.  The final decision as to who wins
the award will be made by the IAC.

The contest will be for three quarters, October 1, 1992 until
December 31, 1992, January 1, 1993 until March 31, 1993 and
lastly, April 1, 1993 until the AVS '93 conference on May 24, 1993.
Submissions for each quarter must be received before midnight on
the final day (EST).

We have selected a lucky winner for the time preceeding Oct 1, 1992.
For his many module contributions and their usefulness to the AVS community
according to our download statistics, we have selected Wes Bethel
from Lawrence Berkeley Laboratories.  We did not want the donations
for the first year to go unrewarded.  Thanks from the IAC and all 
the AVS User community for your more than many module contributions, 
including the following and more:

     avs_arhives contains compressed tar archives of the entire ftp
site.   It was approximately 20MB in size when initially created
(8/11/92), and will continue to grow.  If you want to grab all of the
modules from the ftp site at one time, download these files using binary
ftp.  Then use uncompress and tar to unpack all the files.  Keep in mind 
that after uncompressing, you will be using about 3.5 times the disk space 
as when the file was compressed.  

     AVS is an Archie place holder.

     The AVS_CATALOG provides a complete listing of current module holdings 
at the International AVS Center.  Its general format is as follows:


Name        : animate_file    Version      : 1.000     Mod Number : 1135
Author      : Terry Myerson, International AVS Center (NCSC)
Submitted   : 02/24/92        Last Updated : 02/24/92  Language   : C
Ported to   : DEC Kubota IBM Sun Convex
Description : anim_fname is used to output a series of filenames for input
              into a reader module. The module inputs an integer and a
              filename base, and output a filename in the form "$base.%3d".
              This module is very useful for a series of files containing a
              time series of data.

     AVS_CATALOG, AVS_CATALOG.dvi, and AVS_CATALOG.ps are three versions
of the module catalog maintained at this site.  All three files are 
continuously updated as new modules are added to the ftp site.  The ASCII 
version of the module catalog (AVS_CATALOG) can be retrieved at any time 
by mailing any message to an automatic response script at avsemail@ncsc.org
The AVS_CATALOG.ps and AVS_CATALOG files should be printable on any standard
postscript printing device.  The AVS_CATALOG.dvi file requires a dvi2ps 
utility to be of any use, but provides a much more portable compact format 
for the postscript catalog for those who have this utility available.
NOTE: The AWAIS module, available in the DATA directory on the ftp site,
provides interactive browsing of the module catalog.

     AVS_FLATLINE provides the same information in a format suitable for
some database programs.  The general format for the AVS_FLATLINE file is 
as follows:

animate_file:data_input:anim_fname is used to output a series of filenames for 
input into a reader module. The module inputs an integer and a filename base, 
and output a filename in the form "$base.%3d". This module is very useful for 
a series of files containing a time series of data.:Terry Myerson:International
AVS Center (NCSC):16:C:02/24/92: Kubota Convex DEC IBM Sun:02/24/92:1:1135

     The AVS_LICENSE is a file that provides the conditions under which
modules may be obtained and your agreements to share code with others.  You
must agree to the terms in order to use the International AVS Center repository
and all that it contains.  Its purpose is to ensure the sharing of everything
that has been donated and prohibit misuse of code that has been so generously
donated by others.  If you need a "special" arrangement, you must have a
release in writing from the International AVS Center.  We will contact the
donors and obtain their approval for special cases.  

     You are reading the AVS_README file.

     AVS_USER_REG is a form that can be filled in and sent electronically to
the International AVS Center for registration to various mailing lists,
including AVS User Groups, AVS Special Interest Groups, and a list that
automatically sends you all postings to the comp.graphics.avs newsgroup.
AVS_USER_REG contains detailed instructions on the lists available and where
to send it.

     If you know of anyone, whom does not have news access, they can
download the files in the COMP.GRAPHICS.AVS directory.  These files
are in the standard mailbox format so that anybody can peruse these
files using any mail utility with the -f command.

For example :

  Mail -f May_92

If a "message" in this mailbox is replied to, then a message is sent back
to the poster of the article - but it is not replied to the newsgroup.
The files will be stored in a separate mailbox for each month : May_92 June_92

     The SAMPLE_DATA directory is for data that has no associated
modules.  Many individuals have requested new or interesting sample data
and are also donating it.  It does not fit with the standard module
directories and so has its own directory.

     The FAQ, or Frequently Asked Questions file answers common 
questions about the International AVS Center and AVS in general.

     There are four main directories of modules: DATA, FILTERS, MAPPERS 
and RENDERERS.  These directories correspond to the four columns of modules 
within AVS.

     The SUBMIT directory is for module submissions.  This directory has
write permission and will be explained below in the submission section.
	
     WHAT_IS_AVS is a several page overview of the AVS system.  
 
     WHAT_IS_GOPHER is an overview of the gopher system, and how you
might want to use it to peruse through our ftp site.

     WHAT_IS_WAIS is a several page overview of the Wide Area Information
Server system, and how you might want to use it to peruse through our
anonymous ftp site.

     Your first step, after reading this AVS_README file is to download
the AVS_LICENSE file and read it.  If you have any problem abiding by the
AVS Licensing Agreement, please send email to avs@ncsc.org or US mail to the
International AVS Center, po Box 12889, 3021 Cornwallis road, RTP, NC 27709.
We will try to deal with special circumstances as they arise on a one on one
basis.

USING STANDARD FTP PROTOCOL:

     There are only a few basic commands you will need to move around 
in the AVS directories and download or submit files.  Additional information
is available in your local man pages on ftp.  The first step is to "cd" to
the directory you are interested in such as "cd DATA".  You will receive a
message on how to proceed.  You should then "cd" to the module directory you
want such as "cd abekas".  You should change your settings as follows:  type 
"bin" at the prompt to change to binary mode; type "hash" at the prompt, this 
gives a # sign on your home device that shows you that things are working; type
"prompt" to get multiple files at one time.  There are only a few other 
commands that are general. You should know get and mget.  Typing "get filename" 
at the prompt will download any one file.  Typing "mget filenames" (or with 
wildcards *,?,etc) will get you several files at one time.  If you did not type 
the prompt command you will be asked yes/no for each file.  If you did type 
prompt you will not be prompted, ftp will just continue to download all files 
requested.  The reverse procedure is true when you want to submit modules using 
the put and mput commands ( more on submission later).  
                                            
     In this directory, you will find all of the files for a module.
These include the source code, scripts, networks, helpfiles, and makefiles. 
The Makefiles are named make.platform ( i.e. make.Convex, make.DEC )

     There is another ftp option available for getting a module that
you may find easier.  Suppose you want the module read_tiff, which is
located in the subdirectory DATA/read_tiff.  If you do the following
sequence of steps, you will wind up with a tar file containing all of
read_tiff's files in it:

	ftp avs.ncsc.org
	use anonymous for the userid
	use your userid for the password
	cd DATA
	binary
	get read_tiff.tar
	bye

Then on your local machine, use "tar -xvf read_tiff.tar" to restore
the files from the archive.  This method may take a while due to
the potentially large size of the tar file.  If you use
"get read_tiff.tar.Z" instead, you will get a compressed version of
the tar file, which should come over significantly faster due to
the smaller size.  Then on your local machine, use 
"uncompress read_tiff.tar.Z", followed by "tar -xvf read_tiff.tar"
to restore the files.

                               EMAIL FACILITIES

    It was determined that there were many users who did not have ftp
protocol on their system.  For those individuals an email procedure has
been set up.  There are three email addresses associated with the International
AVS Center.  These are avs@ncsc.org for questions/module submission, 
avsemail@ncsc.org for an automated information request, and avsorder@ncsc.org 
for automated module requests.  avsorder and avsemail are both explained below.
                   
   Mailing to avsemail@ncsc.org will automatically retrieve a response which 
includes this AVS_README file and also a current module catalog.

   Mailing to avsorder@ncsc.org will automatically retrieve module source code.
Since some mail handlers have restrictions on the maximum size of 
a mail message, the modules that are requested will arrive in several
messages - one message per file per module.  Some modules that could be 
requested may also not be deliverable by email because of the size of 
individual files in that module.  These cases will be noted in the return 
email you receive.  Phase II will offer you option of receiving these files 
or any others via tape.  Construction is currently underway of porting 
facilities and as soon as hardware is installed, we will update this notice 
and provide instructions on how to request modules, data, etc. via tape.

    Note that you will need to remove the mail header lines after saving the 
files from within your mail system.  The title for each of a module
file's mail message will be of the form <module name>/<file name>, in
order to facilitate easier saving of these files.

HOW TO ORDER:

1.      First, review the modules available in the AVS_CATALOG

2.      Decide which modules you want.  Add a pound sign (#)
	to the beginning of each module number and make sure it is
	on a separate line of its own for each module ordered.

3.      Submit the order form.  The #module_number and name ( the # 
	is necessary in front of each module ordered with no spaces, 
	as #1037 ).

4.	When your order is filled out send it to "avsorder@ncsc.org",
	it will be processed immediately.  DO NOT send orders to 
	avsemail@ncsc.org or avs@ncsc.org.


        SAMPLE ORDER FORM:

*******************************************************************************
        I would like to order the following modules:

#1005 ( these lines are the module numbers)
#1023 ( NOTE that each entry must be on a separate line, this is required)
#1029 
#1130
..............You may order as many modules as you like as long as each is
..............on a separate line.


Thanks
John Doe
Smurfville, USA  (Full name and address is not required, just requested)

*******************************************************************************

        WHAT THIS ORDER FORM DID FOR YOU:
        
The #numbers order modules 1005, 1023 1129 and 1130 from the module list.
Each number told the automatic ordering service what you wanted in addition 
to the module source code.  Everything is automatic.  If you did not receive 
what you ordered, send email to avs@ncsc.org and we will correct the problem 
quickly. 

*******************************************************************************

BATCH TAPE REQUESTS:

	There is a $5.00 dollar shipping and handling fee for tapes ( $10.00
for shipping out of country and no insurance).  If you send your own tape
this is the only cost incurred.  If you wish us to use one of our tapes we
will charge you cost plus 15% for our ordering, stocking, etc costs.  This 
is still less than retail and is designed only as a cost recovery.  We are
not responsible for items damaged in transit.  Exact costs for tapes and 
handling will be determined when hardware is delivered and set up.  We will
post information as soon as it becomes available

*******************************************************************************

HOW TO SUBMIT MODULES:

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

	There are three ways to submit modules:

	1.	Standard ftp protocol
	2.	email ( no binaries)
	3.	Sending tapes to:	The International AVS Center
					P.O. Box 12889              
					3021 Cornwallis Road
					RTP, NC 27709  
	
	Several individuals have said they would contribute, but from 
past experience they knew they would be bombarded with questions about the 
code and did not have the time to spend replying to these questions.  If 
you are in this situation, we will put a unique control number in the code 
and the International AVS Center will act as the only contact between you 
and the world.  Many of the questions will be fielded by the AVS staff, 
but if a question cannot be answered internally, you will only be contacted 
by the center and not hundreds of individuals.    
                                                                             

*******************************************************************************

STANDARD FTP SUBMISSION:


	 If you have arrived at this point it is assumed that you know the
ftp site name (avs.ncsc.org).  The IPnumber will be changing shortly as
we move to a larger server, so be prepared for this number to change in the
near future.  We will post it later.

        When you login you will get a banner message that will provide some
basic information.  You will then see the following:

AVS_LICENSE      avs_newsgroup/   dev/             usr/
SUBMIT/          avs_readme/      etc/
avs_archives/    avs_user_group/  pub/
avs_modules/     bin/             sample_data/

	Most of the files and directories have been explained above, except
the SUBMIT directory.  The SUBMIT directory is the only one that has write
permission.  In order to provide a minimum level of security to those who
donate modules, and try to make sure others do not accidentally copy over their
files, and to streamline the process of adding your module to the catalog,
we ask you to follow the following procedures.

	Please prepare your submission to conform to the following guidelines
as closely as you can:
	1.	all C source code should have a .c suffix
	2.	all FORTRAN source code should have a .f suffix
	3.	all C header files should have a .h suffix
	4.	all FORTRAN header files should have a .inc suffix
	5.	provide one file with a .txt suffix for each AVS
		module, in plain text format, which provides complete
		documentation for the module
	6.	provide a sample AVS network file, with a .net suffix
	7.	do not include assembly language code

	When you "cd" to the SUBMIT" directory, a banner message will appear
that will prompt you with instructions.  You will be asked to create a
directory using mkdir as in "mkdir myname".  This directory will be  invisible 
and entry into this directory can only be achieved by typing "cd myname".
When someone else logs in, they will see nothing, unless they know the name and
unique number identifier.  After you "cd" to your new directory you will be able
to donate modules using standard ftp protocol.  Detailed information is 
available in the ftp man pages, but you will only need to know a few basic
commands such as bin, hash, prompt, put and mput. to donate your modules.

	You should create additional directories for each module using "mkdir".
If you are submitting multiple modules, please use "mkdir mynameN", where
N would be a unique number for each module being submitted.
You should type "bin" at the command line to change to binary format, then
type "hash" at the command line to show a # sign on your local machine that 
tells you things are working.  You should then type prompt if you have 
more than one file as this lets you download multiple files at one time
using mput without waiting for the prompt yes/no command.  Then type the
command "put myfile" or "mput myfiles" at the command line and they will
download to the new directory you have created.  We prefer and recommend
that all files submitted are only straight ASCII files, although if your 
files are in tar or tar.Z format, we will accept them.

	If you logout and wish to make a change, you must remember the 
unique name for the invisible directory you were given or else start all
over again.


*******************************************************************************

EMAIL SUBMISSION:

	We will accept email submissions to avs@ncsc.org, but ask you follow
these guidelines.

	Do not include any binaries.  If data files are large, put in uucp
format or provide a smaller data file with a note that larger files are 
available.  We will contact you to try to arrange obtaining these larger
files through other methods.  Please do not send data files over 200K.
Separate all files by a line of at least twenty (20) asterisk marks (*) so 
we can search for these easily.  

	Your first lines should describe the module, the platform it has
been ported to and special notes such as large data size, followed by *'s.


*******************************************************************************


BATCH TAPE SUBMISSION:

	To submit a module via tape, put it onto a tape
using "tar -cvf tapedrive filename[s]".  Label the tape with the
appropriate platform the module runs on (and the platform the tape
was made on, if different), and mail it to us at:

        The International AVS Center
        PO Box 12889
        3021 Cornwallis Road
        RTP, NC 27709

1.	 What is the International AVS Center ?

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

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

a 3D computing architecture, high data capacity and bandwidth,
high I/O bandwidth, ultra finegrained parallellism and low cost
of ownership.  It easily connects to a host UNIX workstation
via an industry-standard SCSI interface.  The processing
resources of the DTC are integrated into the host's software
and network environment by multiC, a powerful data-parallel
extension of ANSI C.
How do I download modules from the International AVS Center, or submit modules, or get a list of the currently available modules:how_download:
 ___________________________________________________________________ 

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

        There is an AVS_README file which should answer
these and many other questions for you.  To obtain a
copy of this file, there are two methods currently
available and a third method under development.  Mail
sent to avsemail@ncsc.org will automatically retrieve
a response which includes the AVS_README file and
also a current module catalog.  Or you can ftp to
avs.ncsc.org, login with anonymous as your userid and
your own userid as the password, and get the AVS_README
file and the AVS_CATALOG file from there.  For those users
without ftp capability, there is a tape ordering system
being developed at the International AVS Center.
When I try to run AVS on a remote machine and display the output on an X server, I get a message saying Client unauthorized to connect to server.  How do I fix this:x_help:
 ___________________________________________________________________ 

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

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

        xhost <Client1 machine name> <Client2 machine name> ...
Is there sample AVS data available:sample_data:
 ___________________________________________________________________ 

8.	 Is there sample AVS data available ?

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

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

        Possibly your host machine isn't a registered
internet site.  In such a case, the IP address can't be
mapped by our machine into a valid hostname.  Speak to the

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

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

13.	 What is WAIS and how can I use it at the International AVS Center ?

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

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

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

        We haven't got it yet, but I believe AVS5 has a couple modules
which do this. From AVS Network News (Vol 1, Issue 4):

"ribbons"        :  generates a ribbon representation from the GEOM output of
                     the streamline module
"ucd streamline" :  creates stream ribbons

        Sound like some pretty nice enhancements in AVS5; can't wait to
get it!

Hi,
how do modules with 2 input ports (like convolve ) work.
I suppose it doesn't  make sense to perform any computation
if there is input only on one port; such modules should probably
wait until there are input on both ports. How do they accomplish 
this? Sample code or pseudo-code would be helpful.
Thanks
vp

We have a license for AVS-Animator and are about to buy some video equipment. Our institution is mainly Sun and Mac based. Animator supports Imagenode, the product of Diaquest, I guess. Could anybody share experience with Imagenode, especially:

1) there seems to be a hardware-version and a Mac-based software version (Imagenode option of DQ-Animaq board for Mac) I am mainly interested if these are (99% ?) compatibel and if there are performance or quality differences.

2) there are a number of supported recorders. can anybody comment on the quality of these machines, especially compare Abekas and Sony LVR 5000 (aka Analog Draw?).

I have been told by AVS that there is no intention in supporting
other animation controllers other than the Diaquest one.  As a
user of a Lyon-Lamb minivas that works very nicely I find this
too bad.  I wonder how many people out there would like to see
the animator work with other controllers.  Without support for
the Lyon-Lamb controller the animator is worthless for me.

The trick is to make the input ports REQUIRED.

Terry Myerson's SIDE_BY_SIDE module (on the anonymous ftp site)
has an excellent example of this.  Look for REQUIRED below,  I'll
include the documentation then the source.

Enjoy!

PS  Would you be interested in sharing your AVS work with the
scientific visualization community worldwide via a short article 
and / or slides in an upcoming issue of AVS Network News?  This 
is the IAC's quarterly magazine made up of user contributed 
articles.  Also, we are soliciting short AVS animations on video
tape for the video theater at AVS '93, and posters for the poster
session.  Thanks for considering this!

MODULE NAME : side by side

INPUT  : image 1   	( 2D 4-vector byte )
         image 2   	( 2D 4-vector byte )

OUTPUT : output image   ( 2D 4-vector byte )

Side by side pastes input image 1 and input image 2 together, 
side by side, to produce the output image.  image 1 and image2
must be the same height.  The dimension of the output image is
(width of image 1 + width of image 2)*(height of image 1).
This was used to combine two images for comparison.

Description : The volume mesh module is similar to the volume bounds
              module. The difference is that it generates a mesh using a
              colormap for the desired faces of the irregular field
              instead of a wireframe. This replaces up to six
              ortho_slice/field_to_mesh combinations. By placing the
              crop module upstream, it is easy to control the location of
              the slice planes.

              points data of an input irregular field as the longitude and
              latitude of each point. If the data is 3-D, then concentric
              globes are generated with the radius determined by the
              "radius min" and "radius max" parameters, unless the data
              is 3-space and the "use height data" toggle is on.

Description : The ucd to wave module writes a ucd structure to disk, in
              wavefront format, which is supported by Data Visualizer.
              Ucd to wave works only with node data, therefore if you have
              cell data, you have to transform the cell data to node data
              using the cell to node module. Because Data Visulizer
              doesn't use mid-edge nodes, at this version, the ucd to wave
              module generally doesn't use the mid-edge nodes. One
              exception has been made - if the ucd cell is triangle with all
              mid-edge nodes present, ucd to wave module will split the
              triangle in 4 triangles. The user can change the module to
              support another ucd type which use mid-edge nodes. The
              wavefront file that will be written to disk is an ASCII file.

              the character string to the receiving module, you must make
              that receiving module's parameter port visible. To make a
              parameter port visible, call up the module's Editor Window
              panel by pressing the middle or right mouse button on the
              module icon dimple. Next, look under the "Parameters" list
              to find the parameter you want to plug into. Position the
              mouse cursor over that parameter's button and press any
              mouse button. When the Parameter's Editor Window appears,
              click any mouse button over its "Port Visible" switch. A
              blue-green (teal) parameter port should appear on the
              module icon. Connect this parameter port to the character
              string module icon in the usual way one connects modules.

Hi,
 
I modified the module "field to irreg" from Kathleen M. Dyer.
Before modification it only converted uniform fields to irregular
fields by adding a grid.

After modification it is now possible to convert uniform or
rectilinear fields to irregular fields by adding a grid.

Sincerely,

Is there an HDF Scientific Data Set (SDS) interface to AVS ? I know
the HDF image interface exists. While I am at it, is there anyone
else out there using AVS to visualise models of the Earth's magnetic 
field ? Any information is much appreciated.

A while back, I submitted a module to the AVS center that reads HDF SDS's.
There are several features that make it pretty flexible.  I personally use
it on convex AVS, and AVS running on an SGI.  I hope you find it useful.
Comments and suggestions can be sent to me.

I wouldn't say worthless. We use the animator to generate a sequence
of images which are displayed and then use a handmade minivas module
to control the Lyon-Lamb minivas controller. Works fine.

I am currently working on a module that needs to dynamically
create a network at runtime based on the user's needs.  It's basically
a menuing system.  The method I intended on using was to issue CLI
commands with the AVScommand() function.  The CLI command to create
a module instance is module, and when it is given directly to AVS
when in the CLI mode, it returns the module's unique name.  The problem
is when I issue the module command from my own code using AVScommand().
It never returns the name of the module that is loaded by the module
command, and thus, I am not able to deal with the module just created.
Could anyone give me any help or solutions to this problem?

Thanks in advance,

I posting this to the AVS user community as well as to the AVS developers. 
(We want to gripe!)

Anyway, we've been working on a relatively simple module
to extract from a UCD the nodal and/or cell data to be outputted as fields.
That way, we can use the tools that already exost for modifying 
nodal/cell data as fields.  After modification, we then return the 
data to a second module that puts the modified values back into the
nodes and/or cells.  Sounds useful, eh?

Our need was for a user that had generated UCD data but wanted to colr
it only over a selected range.  If they were fields I'd tell him to
set the colrmap limits or use clamp to adjust the data values.  But
there appears to be no way to do this with UCDs!  The darn ucd_to_contour
module always finds the min max .  Also the ucd_minmax module at
avs.ncsc.org does weird things if any values are above the min max.  So,

So now the real problem.  Has anyone looked at the example ucd modules
in /usr/avs/examples?  Our DEC, Sun, and Convex examples all are putrid!
The C code ucd_thresh contains a call to 'ucd_get_offset' which is completely
undocumented!  WE can't find it anywhere - it must be in a library.  While we
might not need it for our case, it's very poor form to put it in an example
for people to use.  As well as the reference to the ucd_legend structure that
is found (and not documented) in udata.h.  

Lastly, there are no FORTRAN versions.  There should be at least on example
of UCD in a FORTRAN module.  What surprised me is that I have already used
UCD calls in a module to generate a UCD from scratch.  When I try to build the
aforementioned modules that need to read the node or cell data from an
input UCD I get garbage.  I'm essentially unsure whether the ucd_get_node_data
call retreives a pointer to the array of data values or the offset from
a the beginning of the UCD structure in an analogous manner to the
avsfield_get_offset call that I oftern use.  Does anyone have a
working UCD module in FORTRAN?

Well enough gripes.  The modules describe would be very useful.  If anyone
has an example that would help us, I'd be glad to deposit the finished
ucd_extract_field and ucd_add_field modules to the IAC site.

                          San Jose, California


The growing acceptance of parallel computing has led to a recent surge
of interest in parallel rendering techniques for computer graphics
applications.  In response,  a two-day symposium on the subject will be
held as part of Visualization '93.  The symposium will provide a
high-quality technical program in an informal atmosphere.

Papers are solicited on all aspects of parallel rendering, including,
but not limited to:

 	- polygon scan conversion
	- ray tracing
	- radiosity
	- volume rendering
	- constructive solid geometry
	- surface generation
	- scientific visualization
	- massively parallel computation
	- performance analysis
	- I/O and display issues
	- architectural impact on algorithms

Papers are not limited to a visualization context.

Accepted papers will appear in the Symposium proceedings.  In addition,
IEEE Computer Graphics and Applications will publish selected papers in its
July 1994 issue.


SPONSORSHIP

The Parallel Rendering Symposium is being held as part of the
Visualization '93 Conference.  The Conference and Symposium are
sponsored by the IEEE Computer Society Technical Committee on Computer
Graphics In Cooperation with ACM SIGGRAPH. 


SYMPOSIUM FORMAT

In order to foster an informal atmosphere and maximize the exchange of
ideas, attendance will be limited to 100 people.  The technical program
will include a keynote speaker, refereed papers, and panel and group
discussions.  The symposium will also feature two lunches and a dinner
reception.


SCHEDULE

Submission deadline:		March 31, 1993
Notification of acceptance:	May 17, 1993
Final papers due:		July 1, 1993  (tentative)


SUBMISSION INSTRUCTIONS

Authors should submit 5 copies of papers and figures to Tom Crockett,
ICASE, M.S. 132C, NASA Langley Research Center, Hampton, VA  23681-0001.

An input port can be defined as either REQUIRED or OPTIONAL. 
When there are multiple REQUIRED input ports for a module, the 
module does not execute until both ports have valid data on them.  
You can use the library call AVSinput_changed() inside the compute
portion of the module to do conditional execution (like: "only 
re-execute this portion of the code when input3 has been updated")

When some of the ports are OPTIONAL, the module will fire whether or
not there is valid data on the ports.

In general, modules fire when any of their input ports change or any
of their parameters change.

Hope this helps!

You are right - this was poorly implemented the first time around. Here's
how we are fixing it:

We have included UCD_MINMAX as part of the AVS5 release and added the
min/max data information to the UCD structure.  All the AVS5 UCD modules
now use this minmax information rather than always renormalizing the 
colors to the range of the data.  Another situation that motivated these
changes was animating structures over time.  Before, the colormap would
get normalized to each time step (not really useful).  Now, you can 
set the minmax range for the entire time sequence and have the colors
not jump around.

This has proven so important that we are including a MINMAX module for
fields as well in the AVS5 release.  This module basically overwrites
the field's min/max data elements with ones of your own choosing.

: So now the real problem.  Has anyone looked at the example ucd modules
: in /usr/avs/examples?  Our DEC, Sun, and Convex examples all are putrid!
: The C code ucd_thresh contains a call to 'ucd_get_offset' which is completely
: undocumented!  WE can't find it anywhere - it must be in a library.  While we
: might not need it for our case, it's very poor form to put it in an example
: for people to use.  As well as the reference to the ucd_legend structure that
: is found (and not documented) in udata.h.  
: 

You are right about this, it's too late for AVS5 documentation, but we'll
see if we can't make something available via the International AVS Center
or our customer service's listserv mechanism.

: Lastly, there are no FORTRAN versions.  There should be at least on example
: of UCD in a FORTRAN module.  What surprised me is that I have already used
: UCD calls in a module to generate a UCD from scratch.  When I try to build the
: aforementioned modules that need to read the node or cell data from an

: call retreives a pointer to the array of data values or the offset from
: a the beginning of the UCD structure in an analogous manner to the
: avsfield_get_offset call that I oftern use.  Does anyone have a
: working UCD module in FORTRAN?

In AVS5, there is an example module in FORTRAN called gen_ucd.f.  I sent
your message around to the rest of the group and got back the consensus 
that UCD from FORTRAN really didn't work terribly well in AVS4.  Our
beta feedback for AVS5 indicates that this has been remedied.  I'm sure 
you'll check it out when you get the final AVS5 and let us know if that's
really the case!

Incidentally, AVS5 is in the manufacturing process now (tapes, docs,
and CDs) and should be hitting your offices shortly!  Continue keeping
us honest!

This problem sounds just the like the one that I`d like to solve:
How can you make ONE input port connectable to several output ports?
Evidently this must be possible with geometries - e.g. the render geometry input port
accepts several ports to be connected to it.
I`d need this for writing a module that links geometry edit lists: One idea would be to link
 them ``manually`` (handling pointers etc. - though I don`t yet know how this could this be 
implemented in detail). The other possibility would be to write a module that allows geom edit 
lists to be passed through - just copying the input to the output, but with multiple modules
connected to the input port. This should work as the geom edit lists are sent to the input
one after another.
Does anybody know how this could be solved?

Harald,

This is possible, but only for 'builtin' modules - i.e. modules which
are linked in with the kernel.  A reference count is kept for each of
the inputs attached to the port. Each of the viewers (geometry, image, 
and graph) look like real modules but are special 'builtins' in the 
same process as the kernel.

The bottom line is that 'normal' AVS users can't really do this.  One
exception is people who have purchased a 'Developer's AVS' license. 
Among other things, Developer's AVS comes with a libavs.a library 
which lets you link all your modules into the kernel so that your
application is only one process.  In this case, user written modules
which are linked in with the kernel can have multiple input ports,
otherwise, it is restricted by the architecture.

We have handled PHOENICS ASCII output using a "software toolkit" of UNIX tools
we developed some time ago.  These "tools" augment the UNIX utilties and
process ASCII files in a variety of ways.  For PHOENICS, we strip
comment lines, re-align data lines, and then build the appropriate AVS
.fld file for the Read Field module.  I believe that "awk" could do about
everything the "toolkit" can do, but the documentation for the "toolkit"
and the resulting command lines are readable.

We have done an animation of preliminary results on an internal combustion
engine model.  The main problem we have is that the geometry viewer rescales
the image as the region of interest shrinks and grows during the engine
cycle, as we progress from one geometry view to the next.

The displays are quite usable.  The user who produced the PHOENICS results
immediately could see where he had a boundary condition error and went back
to fix it.

Manipulating the Hedgehog plane to remain within the combustion cylinder 
volume is difficult.  I wish there were some way to constrain the plane's
motion to the X, Y, and Z axes.

With the "toolkit" (and years of practice with it), we have been able to
extimate 2 - 4 hours for the first AVS viewing of any ASCII data set.

Since I am just starting out on the road to AVS enlightenment
I thought I'd solicit some advice from you people as to some
useful techniques to visualize borehole data.

I have approx 15 boreholes spatially close together (ie they are about
10 metres in depth and lie within a similarly proportioned triangle but 
don't lie on a grid .... although they cover the triangular area reasonably
evenly) that have samples down the hole spaced at 0.25m intervals. At each
depth point are about 10 seperate measurements.

What different paradigms would you suggest to visualize this?

As a start I have got the wells and the bounding triangular prism
visualized by using the lines_to_geom module from the AVS centre thingy 
but I really don't know where to progress from here.

I guess it is like a lot of complex software suites - you can read the
manuals all you like and play with the provided tutorials, but there is
nothing like (a) practice, (b) knowledgeable gurus :-),

Allen Schiano, OAC/UCI, wrote concerning general gripes about accessing
UCD data and using UCD routine calls in FORTRAN.

I can't agree more about your gripes with UCD routine calls in FORTRAN.
I tried relatively unsuccesfully for quite some time to extract data 
from UCD structures from AVS using UCD routine calls FORTRAN 
(all of my number-crunching routines that use the data are in FORTRAN, 
so why not?). I finally resorted to writing my computation routine in C 
(since you have much more control over structures/pointers/offsets/etc.),
and calling my FORTRAN routines from that, passing all of the pointers 
to the arrays as well as the array sizes down and dimensioning in FORTRAN 
as variable arrays. The nice feature if doing this is that if you have trouble 
with a UCD accesor routine (I CAN'T get UCDstructure_get_node_minmax to work 
in C or FORTRAN), you can access the data directly using the pointers
to the structure (i.e., min_node_data[i] = UCD->min_node_data[i]).

Anyway, I agree that FORTRAN support for AVS is sorely lacking.
I understand that FORTRAN writers probably make up a very small %
of avs users, but if avs is going to support FORTRAN use, it should
truly attempt to support it.

My two cents,

If you have the money, you buy one of the numerous systems that
already does it- StrataModel, EarthVision, Schlumberger's, etc.
If you don't have the money, you re-invent the wheel in AVS.

Use the the geometry data type.
Give it some concreteness by turning line graphs into 3-D objects
by circles-of-revolution.
Annotate and grid a lot, or one will easily get dis-oriented
in the data.

    /* Add a paramter: the transform Time */

    AVSadd_parameter_prop( parm, "local_range", "real", 1.0 );
    AVSadd_parameter_prop( parm, "immediate", "boolean", YES );

I hoped that this would change the local range to 1.0, but it did not work.
The default value remains.

Does anybody know what I am missing? I am using DEC AVS V4.0.

Any help is appreciated

Chih-Ming,

I am not familiar with this module, but it sounds similar to a problem I had
building the 'read_plot3d' module for the DEC OSF/1 AXP system. In this case
some of the module was written in FORTRAN, but the interface to AVS library
services was written in C. What produced the same error message, in this case,
was using the 'f77' driver to perform the link against 'libflow_c' as follows:

   f77 -o read_plot3d read_plot3d.o plot3d_fio.o plot3d_f77a.o  plot3d_f77b.o \
           -L/usr/avs/lib -lflow_c -lm
   ld:
   Unresolved:
   MAIN__
   fort: Severe: Failed while trying to link.
   *** Exit 1

The solution was to use the 'cc' driver to perform the link and include some
of the Fortran libraries as follows:

   cc -o read_plot3d read_plot3d.o plot3d_fio.o plot3d_f77a.o  plot3d_f77b.o \
          -L/usr/avs/lib -lflow_c -lm  -lfor -lFutil -lUfor -lots

(Note: '-lgeom' and '-lutil' are removed from the link line since these links
       are using the shared library 'libflow_c.so' which incorporate libgeom.a
       and libutil.a, along with other libraries; refer to the release notes
       for a complete explanation).

Does this help?

Just writing off the top of my head, but I seem to remember hearing
about other people with similar data at the EPA.  They used the
'scatter' data format (field 1D 3-space irregular N-vector) to 
represent each sample taken and then used the module 'scatter to ucd'
which does a Delauney tetrahedralization to create a 'continuous'
UCD structure which linearly approximates the data 'in-between' the
samples.

Wes Bethel also has some modules at the International AVS Center which
interpolates the data to a regular (uniform) grid.  You should probably
check those out as well. They are called 'scat3d' and 'trivar'.

If you really don't want any interpolation and are content to visualize
the pure data samples, then may I suggest you use the 'bubbleviz' and
'scatter to geom' modules which will create colored spheres whose color
and radii can be tied to different variables.

You have a lot of choices - which may be part of the learning curve
problem.  I hope this gives you some directions to try.

There is an upcoming article in the AVS network news that describes

characterization project.

Anyway, to the question at hand.  What are "boreholes?"  Is it just
a hole in the ground?  If that's all you want to see, then you
can use the module "plot xyz" (reads in polyline segments from your
ascii file) and connect that to "tube" (then on to geometry viewer).
You'll see a bunch of tubes floating in space.

What's this?  You have data too?  It doesn't matter what the data is
for the sake of discussion.  Let's use "olifactory repulsiveness" 
as an example (contrived, silly and easy to deal with, and won't make
me look like a fool talking geo-whatever when that's not my background).  

You pull rocks out of the hole and smell them.  If they don't smell, 
give'em a zero.  If they smell like last month's leftovers in the fridge, 
then give'em a 5.  If your dog runs away, that's a 10.  Ok,
now we have a quantitative scale. 

We can now do many things.  I'll only talk about one so you'll be sure
to check out the May 93 issue of AVS network news.  You can assign
a color to a quantitative scale, like map 0 to white and 10 to 
"crusty-mold green." You can then use the "plot xyz color" module 
(rather than plot_xyx) which will produce colored line segments, using 
your location data, your value data and a colormap.  You can still use
the tube module, because now in AVS 5 the bugs are out and it will
do colored tubes (from either disjoint lines or polylines) and
won't break.  

I don't think you can use "bubbleviz" as shipped with AVS because this
module forces you to use a 3d 3-space field (last time I checked, anyway),
and you don't have that kind of data.  You have 1d 3-space data.  Also,
if you want to look at just the locations, and don't care about the
data, then bubbleviz won't work at all.  There is a "new bubbleviz" module 
at the IAC which fixes this problem though.  Follow bubbleviz with
scatter dots and "connect the dots", possibly following that up with
the tube module and you'll get the same thing as plot_xyz_color->tube.
The only real advantage to this route is then you could pass the
field off to some other modules for doing other vis techniques,
whereas with plot_xyz_color you cast your data into geometry.

The upcoming article describes more vis methods which are conceptually
simple but a pain to pull off.  

In response to the person who said "go buy something that does it
already, else you end up reinventing the wheel.."  There is the
issue of cost.  Many of these other systems are an order of
magnitude more expensive than AVS (which in itself ain't cheap).
If you work for Exxon or something then you have beaucoup d'argent,
and cost isn't an issue.  But if you work for a university then your 
time is much more expendable than cash.  C'est la vie.  Further,
the process of reinventing the wheel will force you to clearly understand
what you are doing rather than blindly letting a canned piece of software
do everything for you.  Some of those systems are pretty nice, though.
I've seen them and they do a lot.

Thanx for the info Wes (as well as Larry & Richard). I'll may sure I 
pass on the 'smell the rocks' advice :-)

I actually concur with your comment above. We are a research lab offering
services to our corporate divisions (we are a big mining/oil & gas/steel
company) and yes, for some of the project work for say the petroleum guys,
a package such as StrataModel would do the trick just nicely.

Problem is, we do work for lots of differnet groups using all sorts of data.
If we went out and bought the specialist stuff for all these we'd have a
budget blowout comparable to the size of our national debt :)  Well, I
have to admit we've done it once ..... we were involved with the develpment
of VoxelGeo which is great for 3-D seismic!

AVS nicely fits the niche of going a long way towards allowing us to do work
with many people, not just the few whose data exactly fits the more
specialist applications,

Chih-Ming,

This is due to a bug in LBL_bezier_v/opacity.c. The second to last executable
line should read:

     free(sizes);

and not:

     free(layers);

In general, I've found that DEC OSF/1 for AXP systems will be much less
forgiving on these types of bugs.

Chih-Ming,

By the way, you too could have debugged this problem since you have the
sources and a great tool called 'avs_dbx'.

Please continue to post any and all comments about AVS on this new machine,
good or bad. I'm sure the entire AVS community would soon like to have an
Alpha when 3D hardware support comes out ( soon->PXG ).

For general interest....

We've just completed an animation of a synthetic flight over
topographic elevation data texture mapped with satellite
imagery. The imagery and elevation data sets are from the
Sarajevo region (former Yugoslavia and a current hotbed of
some nasty fighting). The animation was done for an ABC
News Special, hosted by Peter Jennings and to air 18-March
at 8pm (EST).

So what? Well nearly all of the production, from data ingest,
psuedo coloring of the IR multi-spectral imagery (SPOT),
spatial sharpening with higher resolution panchromatic data
(also SPOT), image/elevation data set registration, flight
path inspection, rendering, and recording to an Abekas A66
was done in AVS5 on a Silicon Graphics workstation.

So, check out AVS functionality in generating what used to
be a very painful production process (for us). Well, it was
still painful... but it took alot less time than our previous
endeavors

We made two sequences. One, we're told, will be used in the
opening of the show.

Speaking of 3D hardware support for the Alpha's,
we just got a new Alpha machine last week, and I'm wondering
what the schedule on that is (including PXG).

Can Hugh or anyone at DEC shed some light?

Lee,

   Hopefully you have received your demo copy of SciViz REV 1.1 which 
contains a Fidap reader.  Our product is based on a meta file format
which we have other readers for as well including:

   MSC / NASTRAN
   FIDAP
   STAR-CD
   LS-DYNA 3D
   ABAQUS
   DYTRAN
   PAM-CRASH
   ANSYS
   and more soon.

   Within the SciViz REV 1.1 distribution is a "Read Meta" module and a 
sample advanced.net network.  You can use the "Read Meta" module just as
you would the "read ucd" module in any network.  The "Read Meta" module
converts the meta file directly into AVS UCD format.  

   Don't hesitate to call if you have any problems with the reader, or
installing the demo software.

Lee

I have experience working with a number of customers and prospects using AVS
to visualize the results.  People are normally very impressed with the output,
although, as you might expect, AVS does not do exactly what everyone wants!!

I know of readers for FLOW3D, PHEONICS and STAR_CD.  The first two are available
from NCSC for free, the latter will be released by my company, Tessella,
shortly.  Flow3D release 3 actually writes AVS UCD files.

Work we are doing for our customers will allow them more direct control
over slice planes and seeding lines/planes: manipulation of these in the
geometry viewer is very nice until you want results!!

Other work will allow scales and data values to be displayed.

Current techniques include vectors, isosurfaces, streamlines, stream ribbons,
contour planes, particle animation .....  All-in-all, whatever data you
generate, you will be able to display in a meaningful way!!

Hope this is of use and interest.  Mail me if you want any more info.

Regards

Mark.

We have handled PHOENICS ASCII output using a "software toolkit" of UNIX tools
we developed some time ago.  These "tools" augment the UNIX utilties and
process ASCII files in a variety of ways.  For PHOENICS, we strip
comment lines, re-align data lines, and then build the appropriate AVS
.fld file for the Read Field module.  I believe that "awk" could do about
everything the "toolkit" can do, but the documentation for the "toolkit"
and the resulting command lines are readable.

We have done an animation of preliminary results on an internal combustion
engine model.  The main problem we have is that the geometry viewer rescales
the image as the region of interest shrinks and grows during the engine
cycle, as we progress from one geometry view to the next.

The displays are quite usable.  The user who produced the PHOENICS results
immediately could see where he had a boundary condition error and went back
to fix it.

Manipulating the Hedgehog plane to remain within the combustion cylinder
volume is difficult.  I wish there were some way to constrain the plane's
motion to the X, Y, and Z axes.

With the "toolkit" (and years of practice with it), we have been able to
extimate 2 - 4 hours for the first AVS viewing of any ASCII data set.

modules to import data, filter it, and turn it into geometry data. I plan
to use C++, and have the ObjectCenter development system.  Is anybody using
C++?  If so, are there any common problems or gotchas, such as library
conflicts?  Does anybody have C++ bindings for AVS data structures and
module commands?

Anybody out there using B-spline wavelets for interpolation?

Probably your module seg faulted and dumped core while the AVS kernel was
attempting the identification communication start-up phase.

Start a module debugging session with the command "avs_dbx -id <your-module>"
and then try to read the module using AVS.

Hi,

Does anyone know of a technique for preventing the user from roaming an image which is being displayed in image viewer?  I want the right mouse button to have no effect on the images in the image viewer.

A capability exists for preventing the scaling of an image viewer image using the CLI command:
	image_set_scale_control 0 0

Similarly, the camera inside the geometry viewer can be set to a fixed location by using the geom_set_freeze_camera CLI command.

	Thanks for your comments,
		Jeff

Pardon my bandwidth, but I was wondering whether anyone would like
to share a room at the Walt Disney Dophin for AVS '93.  I would like
to stay there, but us humble public servants only get $58 a day for
lodging, and the "government rate" for a single is $110!   I don't
smoke, I don't snore, and I'm basically a good guy!

Today Japanese companies own the 7/11 store chain, Dunlop, Universal Pictures, 
Columbia Pictures, Loews Theaters, MCA Home Entertainment, Tri-Star Pictures, 
CBS Records, Columbia Records, Spencers stores, Ciniplex Odeon (a big part),
Firestone Tires and many many more very large US companies while foreigners
are prevented from owning any important Japanese concerns. Ordinary Japanese 
are kind wonderful people, but what their companies and government are doing 
is racist and wrong.
 
     To find out more about this (and get a more complete list of the above), 
read (JAPANYES) "Does America Say Yes To Japan?";Leclerc 1992,93 which is 
available on INTERNET. (most recent edition is v031993). This thoughtfully 
written and important article has been circulating widely in many of America's 
biggest corporations & universities like IBM & Harvard. When you read it (it 
takes about 30 minutes), you'll see why.
 
     The essay provides a frightening yet fascinating detailed, referenced 
overview of the Japanese industrial machine at work and how Japan practices 
'business is war' strategies to target and take over strategic critical U.S. 
industries like high technology, popular media and heavy industry as well as 
influence the decisions of the US government in favor of Japan. It is a very 
moving piece and is filled with many verifiable and disturbing examples. 
You can get JAPANYES 1 of 3 ways:
 
1)FTP to monu6.cc.monash.edu.au   it's in directory: pub/nihongo   as: JAPANYES
2)The article has been posted in its entirety (in three sections however)
  in the misc.test & soc.culture.usa & sci.econ newsgroups. Search on the
  author 'buzy' or the title 'article' to find the posts.
3)Email a request for JAPANYES to ar12@midway.uchicago.edu
  He will email you a copy.

Enough changes have been made to the last Beta release of the Keyframe
Animator (V3.0b) that I decided to go ahead and release V3.0b2 and wait
until we get AVS5 and I can ensure that it will run properly under AVS5
before I release it as V3.0.  This version has some majot bug fixes over
the last version (even though it's still Beta) that I would recommend 
that anyone using V3.0b go ahead and grab the new one from
ftp.cica.indiana.edu in the directory pub/avs/Keyframe.  Version 3.0
will be released sometime in the next few weeks.

For those who don't know, the Keyframe Animator is a public domain
module that allows users of AVS4 (and probably AVS5) to animate objects.
Grab the file Keyframe.tar.Z and read the CHANGES, README, and
Keyframe.txt files for more details.

As always, comments, questions, and suggestions are welcome.

Date: Wed, 24 Mar 1993 02:03:46 GMT

Name        : trigger_int     Version      : 1.000     Mod Number : 1601 
Author      : Wes Bethel, Lawrence Berkeley Laboratory
Submitted   : 03/23/93        Last Updated : 03/23/93  Language   : C        
Ported to   : DEC Convex HP IBM
Description : The trigger int module waits for a field to be presented on
              its input port. When a field (new data) is detected, an
              integer is stuffed into the output port. The value of the
              integer is determined by the "start value" parmeter for the
              first execution. Subsequent invocations cause a static
              variable to be incremented according to the parameter
              "increment." This module is useful in creating networks to
              facilitate animations based upon a single coroutine.

	We are looking for posters that present the research done as
well as the graphics or visualization used to display and study the
results of the research.  The audience will be composed of technical
and non-technical people from many different fields, so the poster
material does not need to be at a level suitable for your scientific
peers.

	Posters should take the form of traditional posterboard (see
guidelines below).

	For each poster session presentation, we will need to receive
a short (paragraph or two) abstract of the research no later than 
April 1st, 1993.

	Posters will be displayed in an open area during all three 
days of the conference.

	We recommend that the scientist or a representative of their
respective organization be available to answer questions regarding the
poster content during some portion of the lunch break (11:00-2:45pm
Monday and Tuesday, 11:00-1:45pm on Wednesday).

Guidelines for Posterboard Displays:
------------------------------------

    Size of posterboard available: 30"x40".

    Posters will be displayed on easels.

    Black & white laserprinter output or color prints are examples of
    how your graphical results may be displayed.  We can provide
    assistance in making color prints for you on our Kodak printer.
    These are high-quality glossy color prints that can be made in two
    sizes: 8 1/2" x 11" or 11" x 11".  We will need to get the files
    containing your images by April 26th, 1993 in order to have time to 
    make the color prints for you.  We can convert most any type of color 
    image (color Postscript, AVS image files, XWD files, HDF files, PICT 
    files, RGB images, and many others) into a format suitable for making a 
    color print.

Requests for information and Submissions
----------------------------------------
     	If you have any questions concerning the poster session or if
you wish to present a poster at AVS '93 May 24-26th contact Katie
Mohrfeld (avs@ncsc.org or 919/248-1128).

	Please submit your posters to the International AVS
Center by May 1st, 1993.  We will be responsible for displaying your
materials at the conference.  Please include the following information:

	- a list of the items that are part of your poster
	- the title and author names and affiliations

Scientific visualization is an important research frontier shared 
by a variety of computational science and engineering fields. 
Visualization work is both interdisciplinary and a field in its own 
right.  This conference focuses on interdisciplinary methods and 
supports collaboration among the developers and users of visualization 
methods across all of science, engineering, and commerce.

Tutorials in Visualization conferences are geared to educate both
practitioners and researchers in fields that relate to scientific
visualization. Tutorials can aim at surveying background material 
useful for a variety of visualization tasks, present research
advances in key technologies, or teach general theory and practice
with emphasis on visualization applications.

Half-day and full-day tutorials will be offered on Monday and
Tuesday, October 25-26, 1993. Tutorials are usually, but not
restricted to, presentation-style courses where the presenters use
transparencies, slides, video and interactive demonstrations, where
appropriate. Tutorials can be at the beginning, intermediate, or
advanced levels.

Tutorial subjects include, but are not limited to:
 - Volume visualization
 - Virtual reality
 - Perception
 - Color theory
 - Vector fields and flows
 - Multimedia
 - Visualization techniques
 - User interfaces
 - Data sonification
 - Visualization in Biomedicine



                 Tutorial Proposals are due March 31, 1993.

Due to numerous requests for more information on various workshops to
be held at AVS'93, the IAC has added a directory containing this info
to their anonymous ftp site.  This information is in /avs93/what_is/.
Information is currently available for the SurfCube workshop.  Information
about other workshops will be added soon.

Does anyone have any example code that shows how to do
the following:

   - input a geometry
   - alter the geometry
   - output the new geometry

The only examples I've found on the ftp site use the routine
'AVSset_module_name' which I can't find any documentation on
and so therefore, I hesitate to use it.

Thanks,

 -Will

I have a map which pipes data from the OrthoSlicer into the Graph
Viewer.  I'd like to be able to use the feature of Graph Viewer that's
available when inputting fields "manually" into Graph Viewer, whereby
you can specify a "color column" - a column in the incoming data file
that represents color indices into the color map.  Is there any way to
emulate this when the incoming field is coming from OrthoSlicer?  Or
alternatively, is there a way to edit the color map that the Graph
Viewer uses?  (I'd like to get just 3 discrete colors applied to the
range of incoming data.)

Thanks for any assistance.

- Glenn
