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.
