DotProduct3 Lighting

DotProduct3 can do really per-pixel lighting without pixel shader, this feature only need a Geforce 256 level accelerator. For dot3 lighting, your need check 3d object's 'Bump' style, and create material which has normal map & dot3 shader file loaded, and set normal map to the 1st texture of material. All dot3 shader files can be found at the "effects\dot3" folder.
