[osg-users] Bump mapping question

in the link: http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a01058.html#_details
it says:

"Note that both diffuse and normal map textures must have
corresponding UV maps defined in Geometry objects"

Is there a way to generate the UV map programmatically? Can I just use
the osg equivalent to OpenGL's GL_TEXTURE_GEN_S, GL_TEXTURE_GEN_T?
