CICA AVS3 MODULES

For those users of AVS, we have developed some modules that might interest
you.  They facilitate single-frame recording of animations from an AVS
network and interactive creation of keyframe animations of AVS objects.
Brief descriptions of the "Keyframe Animator" and "Record Animation"
modules follow.  Full documentation for the modules is available.

Keyframe Animator
   Does interactive keyframe animation of any number of AVS objects.
   Rotations can be interpolated using either quaternions or regular
   matrix methods.  Objects can also be translated, scaled, and parented
   to other objects.  Rotations, translations, and scales can be interpolated
   linearly or using splines.

Record Animation
   Facilitates single-frame recording to either a Lyon-Lamb MiniVAS Videotape
   Controller or a Sony Laser Videodisc Recorder.  Frames to be recorded can
   be specified in a variety of ways.  Both devices can be controlled 
   interactively from the computer (play, rewind, fast-forward, etc.).
   RS170 recording is handled automatically.

Both modules run as-is only under AVS3.  They would require some modification
to run under AVS2, and wouldn't be as useful under AVS2 since single-frame
recording requires close synchronization of modules which is assured with
upstream data passing (allowed only in AVS3).  

The modules and documentation are available via anonymous ftp from 
cica.cica.indiana.edu (129.79.20.22) in the sub-directory pub/AVS.  
This software is free, but we ask that you fill out the registration form
included in the file REGISTRATION, let us know of any enhancements you make 
to the software, that you acknowledge where the software came from if you 
choose to use parts of it in your own programs, and that you offer any 
programs that contain all or part of the code free of charge to anyone who 
wants it.  We are also interested in any comments you might have, or features 
and enhancements you would like to see in future releases.  We are interested 
in keeping track of who is using the modules so that we can inform you of 
future releases, enhancements, and modifications.  Please mail the 
registration form to:
