Fake bump mapping

From Free net encyclopedia

Current revision

Programmers of 3D graphics sometimes use computationally cheaper fake bump mapping techniques in order to a simulate bump mapping. One such method uses texel index alteration instead of altering surface normals, often used for '2D' bump mapping. As of GeForce 2 class card this technique is implemented in graphics accelerator hardware.
