Hello,
i've a problem with the collision detection system. I'm trying to
collidate a IndexedTriangleArray(ita) with another Shape.
Sometimes it works fine, sometimes occurs that only the half part of the
ita(its a rectangular) is been detected. I tryied and retried but i havnt
found the problem.

Subject: [JAVA3D] Collision Detection and stopping mov
hi everyone,
I could really do with some help in implementing
collision :(
I have 2 objects, one in a static, fixed position
and the other (a colorcube) moving towards it, I cannot seem to stop the moving
object once it comes into contact/collides with the fixed one and it just passes

Hi, I'm deeply interested in implementing VRML Browser with Java3D.
I want my browser to support collision detection.
But I can't find any sample codes, souces implement collision detections in Java3D.
Help me...
Thanks for reading..

Anders,
To use Java 3D collision detection you want to use a Behavior with a
WakeupOnCollisionEntry / Exit condition. Create some geometry to represent
the viewer (an avatar) and check for collisions between this geometry and
the geometry in your scene.
You either have to manually assign collisi
