Hello,
        I've produced an image of the earth with a pfGeoSet using a triangle
strip, and textured it with an rgb file for realism. My problem is that I
can't seem to get the culling to operate properly. I can see one side of the
earth through the other. I added this to my GeoSet making routine,
        pfGStateMode (gstate, PFSTATE_CULLFACE, PFCF_BACK);
but I am displaying it with a seperate application.

I had expected this to do the trick, but I can't find any documentation on
Culling procedures for objects like mine. How can I get the polygons in the
back to be Culled?

        Thanks in advance,
        Aubrey Holland
