Hi,

Try GraphicsConfigTemplate3D
  public void setDepthSize(int value)

instead of using the default return from SimpleUniverse.

See 4760874 -  Java3D 1.3 OpenGL version on Matrox 450 no supported
Graphics Configurations


I submitted the related bug 4760874, and finally got a chance to submit a
followup/comment on the bug I submitted and the other one.  Since the default
graphics configuration asks for 16 bit Z-buffering, and the Matrox driver for
some reason only supplies about 12 bits of Z-buffering, the system finds no
supported configurations.  Luckily, the driver does have an option to support 32
bit Z-buffering, and with that enabled there aren't any problems (with this anyway).

Personally, since there is a driver option which will fix the problem, I would
much rather use the driver option than have to patch the Sun demo's and everyone
else's code to run on my work computer.  Either that or get a different graphics
card.
