You will get accumulated modelview transformation matrix for each nodes in
RenderContext. This is calculated during render traversal.

This will not help you anyway. This is applicable only for Viewpoint node
and some sensor nodes. Though there are problems with this as a node can
have multiple parents (DEF/USE).
