I wouldn't call the Open Inventor file format public domain unless we've
seen something from SGI that declares it in the public domain. However, I
wouldn't expect to get any hassle from SGI just because we display objects
by reading in files that use the Inventor format.
Also, I believe that the other platforms will not have Open Inventor until
late this year. The only company I know of that is working on a port is
Portable Graphics.
I don't think we need Open Inventor on any platform (although it would sure
make our programming significantly easier.) I think we should try to use
the file format for storing the models and add a few "node" types for
moving around the web.
I like the file format because it is well documented, fairly complete for
scene description, plenty of modeling tools, and it has been around for a
while. I think we could adapt it to our needs. (By the way, as someone
requested in an earlier note, it does allow both matrices and individual
elements to describe transformations - translations, rotations, scales, or
full matrix.)
