QD3D 36 - The Backfacing Option (8-Apr-96)

QDoes QuickDraw 3D have an option or backfacing style which flips the faces' surface normals when I'm on the inside of my model?

ANo. 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).
