Future Considerations

  • Are there any other mesh object file formats that might be useful to us?
  • Create our own, compressed, sound file format?
  • Support the OggVorbis formats?
  • Create our own file format that can be used to store custom force-feedback data?
  • We need to support a codec that supports video playback, preferably without the need to pay any royalties and/or licensing fees?
  • Support AIF, AIFF audio files.
