Hi Drake,
just guessing by the subject of the email. If you want to store matrix to
some node (your child node) you can use the userdata of the node and
RefMatrix. Something like
osg::Matrix parentMatrix;
child->setUserData(new osg::RefMatrix(parentMatrix));
then dynamic_cast the userData to RefMatrix when you need it
Again, the hint is just by guessing. Robert is right, it is not clear what
you are after
Cheers,
Nick
