What ARE you doing Vladimir? Sounds remarkably like some of the problems
I'm having.
What I have done is to subclass Shape3D to include a reportPosition method,
then use this with the collision detector, passing (this) to the collision
detector as a parameter. I can then quiz the parent. I've had ne end of
difficulties with the bounds calls from sceneGraphPath. It always seems to
want to return a box, even if you set the bounds to be a sphere. Doesn't
happen with getCollisionBounds though.
Unfortunately, even if you did get the bounds, all you get is local
coordinates, so both objects are centred at 0,0,0! I think you need to do
a localToVWorld transformation as well.
I'm working on this at the moment and should have some sort of answer
within about a week I would guess.
