I'm not actually familiar U3D but I do know that OpenGL has no concept
of file formats or even in memory formats for models for that matter.
Your best approach, I think, would be to base your scene graph, model
objects, etc according to the U3D philosophy of how these things
should work. You'll find it much easier to then serialize your objects
down to the U3D format. And the OpenGL APIs are flexible enough that
you'll be able to get model data to them reasonably easily.
As far as Apple automatically embedding U3D into PDF I would be
surprised if this is something they'd do. Apple currently supports no
high-level 3D API so fancy support for combining object data and PDFs
is very unlikely.
Sorry for the bad news. :)
Take care,
Guy
