Hello James,
It's such a fundamental aspect of a scenegraph. From all the example's
I've seen in osg, everything is put on the root level. There's no
concept of a local coordinate system based on some (root) object.
Of course there is.
MatrixTransform:
http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a01482.html
PositionAttitudeTransform:
http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a01587.html
DOFTransform:
http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a01288.html
All of which derive from osg::Transform, and change the local coordinate
system as you expect, and which under the covers work as you described
would be done in straight OpenGL. You just don't have to worry about it,
you use them and they take care of the rest.
I'm sure if you search all the examples for osg::MatrixTransform you'll
come up with a few results (being sarcastic here :-) ).
J-S
