Ilan,

 I guess your Java3D was unable to find your video
card.
 some tips :
 * use 16 or 32 color bits depth; (256 colors will not
run)
 * set Z-Buffer depth to (real)32 bits; (Kyro, Matrox
and other vcards tries to cheat Z-Buffer, but  Java3D
does not accept it);
 * if you have more than one video device (onBoard
video plus AGP/PCI video card), disable one and use
just the default.

  If you describe your system maybe we can help you
better.
CPU, O.S.,video card model, etc.
