I am trying to implement a rudimentary inter-object collision between DynamicTransforms by checking their bounding boxes and have struck a few problems. (Yes, I know that RigidBodyPhysics has inter-object collision)

MatrixTransform has a transformedBound field that I thought I could use. However, it gets set initially, but it doesn't seem to change as the translation changes.

DynamicTransforms don't seem to get the transformedBound field set at all.

Is there a way to get a boxBound of a Transform and DynamicTranform that incloses its children and is always current?

Should I be trying a different method?

Thanks.

It should change as soon as the matrix updates. It works find for the DynamicTransform example. I implemented some code in H3DLoad to see if center and size changed and it does so properly.
