It is a lot better to create a loader/editor of binary geometry, than to
encode it into classes. You would need such format anyway, as java
source would hard to parse back into editor. With just model, you create
a structure in memory - it takes only as much memory as needed. With
java class you end up wasting memory for class itself, which probably
won't be freed until end of program.
For the binary format for j3d I would suggest you looking at j3fly
program - it has prototype implementation of such beast.
So only part of idea which is left is actual java3d editor. Having
editor with full support for Morph, OrientedShape, AlternateAppearance
and Behaviours could be nice. Preview mode should be trivial - same
scenegraph could be displayed and serialized using j3fly program. As for
the modelling/editing scenegraph... this is a big task. Look at OpenFX,
3D Studio etc - these are really large programs.
