Some thoughts on the WWW-VRML. Forgive me if some of these things have
been covered already.
For people with text-only readers, perhaps one way to make the VRML stuff
backward compatible would be to include a text description of each item in
the scene. For instance a cube sitting on the ground might include the
comment (or SoLabel, for Open Inventor) "There is a box sitting on the
ground." or "There is a small red box sitting next to the wall on the
ground", similar to the way MUD's describe items. A non-VR user could then
read the text and click on the text to find out what is in the box. It
might provide a speedy link through some rich environments on other
continents besides not handicapping the blind or the VRMosaic-impaired.
Although a text viewer would limit interactions in some ways, it merits
some consideration.
