My use of Java3D is in the CAD/CAM area and I have little requirement for
change apart from a few bug fixes, stability and cross platform
availability.
For my type of application Java3D is pretty close to perfect. Performance
is quite good enough. Flexibility and programming productivity is
excellent.
I would very much NOT like to see Java3D go the way that XJ3D took Sun's
VRML97 loader i.e. into the bloat wear sprawl arena. Something which no
longer met the need for a VRML loader as well as the original, while trying
to suppress interest and availability in / of the original.
I completely concur with Gili's summary included below.

Subject: Re: [JAVA3D] What do you want/need from Java3D?
Justin,
My feedback is short and to the point (and I think Sun is thinking
in this direction
anyway):
Separate Java3D into two components:
- OpenGL binding (very thin layer on top of native OpenGL
implementation)
- Java3D (open-source like the JDK classes, fits on top of OpenGL
binding)
OpenGL binding is platform specific
Java3D is platform-independant
The basic idea with Java3D is that Sun should do two things:
- Reduce their cost of maintainance by offloading the major work to the
OpenGL
binding which would be provided by 3D parties (not Sun). Sun should however
come
up with the OpenGL binding specification and make it standard.
- Make Java3D open-source so their customers no longer worry about Java3D
not
having a future. Releasing sources is a great way to make your customers'
tensions go
away.. worse case scenerio if Sun can't fix their bugs they can fix it
themselves and ship
it to a customer. For a lot of companies, this guarantee means a lot.
Anyway, that's my 2 cents.. Sun should standard OpenGL binding
specification
(but not implement it for all platforms, let other people do that) and it
should standardize
and implement the reference-implementation of Java3D on Win32.
