I liked the subset of Inventor you selected in your proposal
for VRML, but have reservations about how Inventor scene graphs
are expressed as ASCII text. In particular, I think we should
be using a structured programming style which is cleaner and easier
to read and modify. Computer science has come a long way from the
bad old days of using flow charts for program design. An explicit
syntax for scene graphs with separator nodes etc. is hard to read
and understand in just the same way that flow charts were.
I will work through the Inventor Mentor and your proposal to try
and come up with cleaner syntax than can be easily parsed into
the underlying scene graph.
