[JAVA3D] (Important!!) Viewer/Object Collision Detection

[Zak Nixon]

Is anyone using the j3d.org navigation capabilities with collision detection implemented? If so, can someone send me a working demo that shows the collision detection working?   I have tried all the demos included with the j3d.org package, and none of them use the collision detection feature. Also, i have tried to make the collision detection work, but have failed.   Thanks in advance,   Zak
