  If you look at the code here:

 it appears that the light being added IS specified in the AC3D file, so
OSG is adding the light, as directed.

  Well, OSG does handle more than triangles (QUADS, TRISTRIPS, etc) but
modern OpenGL actually only handle triangles internally and trianlges is
what it renders best. Are you asking if OSG supports pure CSG primitives?
it does not, because OpenGL does not.
