[JAVA3D] Collision Detection - Need Normal

[Keith Johnston]

Once a collision has occurred and a behavior triggered - is there a way to get the normal of the face of the object with which the collision occurred?   I read something on www.j3d.org that suggesting using the PickTool and a bounds area to check for the object that you have collided with.  I tried this, but have a couple questions: - Does the PickTool exclude the object that caused the collision?  I only want to pick out the object that the object collided with. - Does the bounds for a Primitive shape automatically get updated as the object moves?  I tried printing out the bounds for the moving object and it stayed the same - so do I need to transform it to another coordinate system before passing it into the PickTool?   Or is there a better way?   Thanks, Keith
