I'm wondering what the different modes for GLModel drawing are. So far, though guessing and trial and error I've found that these work:

• TRIANGLE_STRIP
• QUAD_STRIP
• GLModel.LINE_STRIP
• GLModel.LINE_LOOP
• GLModel.POINT_SPRITES

What I would be most interested in is a mode that could work for more complex shapes: shapes that would require more than one triangle strip, or better yet, vertexes connected to each other (via edges) arbitrarily (the sort of thing you would see in Blender). That sort of thing doesn't seem to be supported by the GLModel class or the GLGraphics library (right?), but I'm wondering what it does support.
