I don't think the acronym VRML was lightly chosen. Bearing this in mind,
things related to the Virtual Reality Modeling Language should be considered
topical no? I would think that this includes much more than graphics.
I think that the "Sound, Servers, MUSH, Multi User interaction, Static vs.
Dynamic, and Networking" subjects are topical. Furthermore even if one is
solely concerned with graphics (in the VRML context) I think that it is
important to understand what role graphics play in the reality model defined
by VRML.
