The Scene Description looks similar to VRML. Is it?


The scene description has several similarities to VRML, as the set of nodes defined by VRML was used as an initial set of composition nodes for MPEG-4. The environment that MPEG-4 addresses, however, is quite different from VRML because a key requirement is support for high quality real-time audio-visual content. In addition, rather than using a static scene description, MPEG-4 defines a dynamic one in which objects can be added, changed, or removed from the scene description at any point in time. The MPEG group collaborates closely with VRML in order to ensure alignment and maximize the synergy of the work of both international bodies.
