hi,
you know, that a transformgroup node is a coordinate system relative to its parent node
? that is, transforming an object does not affect any parent nodes. you just need some
behavior to perform the desired transformation against the node in question. this
behavior needs a reference to the scenegraph (via a branchgroup) and a reference to
the transformgroup that should be performed. then this behavior must modify the
transform3d of this node. that's all.
