MPEG-4 based recording and replay of collaborative virtual reality sessions

The growing complexity of Virtual Reality simulations and the inclusion of a greater range and number of events and interactions in such simulations precipitates the need for the recording of these events to allow their subsequent viewing, discussion and perhaps modification. Furthermore, storage of such recordings in a format defined by an international standard allows their easy use and accessibility as well as distribution. This paper presents a framework for MPEG-4 based recording and replay of Virtual Reality sessions.
