[osg-users] Render normal vectors to image

[Glenn Waldron]

You're welcome.

You might be able to use the osgDB::Registry::setReadFileCallback() method
to intercept read calls. At that point you can generate your normals (for
example run the osgUtil::SmoothingVisitor) and then return the result to
the system.
