QD3D 36 - The Backfacing Option (8-Apr-96)
Q Does QuickDraw 3D have an option or backfacing style which flips the faces'
surface normals when I'm on the inside of my model?
A No. Your app has to detect whether your camera location is on the inside or
outside of a geometry. When your camera is inside your geometry, set the
geometry's backfacingStyle to kQ3BackfacingStyleFlip (assuming your surface
normals face outwards).
