Bump Mapped Golfball |
This is a sphere bump mapped with a repeating 8-bit dimple texture map. The bump mapping function uses the U & V tangent vectors generated by the sphere primitive to provide true 2D bump mapping (not to be confused with 3D procedural bump mapping). Also, an 8-bit grayscale image is used to texture map the words ''NuGraf Bump Mapping'' onto the golf ball.
