This is terrific -- we really haven't had anyone seriously go after this. I
just threw together some code to get the job done. Anything like this is
most welcome, and I will certainly support it. Angel, how would you like to
take a crack at optimizing the VRML export code? I can help you with
anything you want. Mostly we have the issue that there are two types of
coordinates -- Cartesian and screen. But you can transform from one to
another when necessary. We use the macro idea in the POVRAY exporter.
This is a good way to do it -- some hand coding, then get the code to
reproduce that.
Also, I ran into a problem with planes that I'm not sure how to get around.
It appears that isosurfaces and planes in VRML are one-sided. I mean REALLY
one-sided-- viewed from one side you see the color, and from the other side
you see nothing. The plane just disappears. We could use a solution to that.
Planes and isosurfaces are actually huge collections of vertices, faces,
normals, and colors. Don't expect much optimization of those. (Although I do
think the normals could be optimized similarly to the way colors are
optimized.)
