Hardware Transform and Lightning - This is the BIG one. "Uploading" static models
(read world and background geometry) for the card to hardware transform and light
for the view.
Hardware Clipping - Now this one we get for free because it will clip no matter
what, but we should be able to disable clipping in the Java3D scene graph because
it is a waste of processing if you have this hardware.
Vertex morphing/skinning - I just got my vertex skinning code to work with the
GeometryUpdate callback in Geometry but the API should be following the cards
developments.
Bump Mapping - and other pre-pixel rendering options, specular maps.
Cube Environment Mapping -
Cool old hardware features...in the API
Stereo - I have to different workstation OpenGL cards - HP-FX6 and 3DLabs Oxygen,
that support stereo, and Java3D does not work correctly with them. See earlier
email.
3D Textures - Have to see how it works when I get my GeForce2 next week! :-)
Anti-Aliasing - again it didn't work correctly with the two previous cards. - at
least it's in the API.
Multi-Texturing - can't say thank you enough.
That's all I can think of for now...
