Information About

Per-pixel Lighting




Per-pixel lighting is commonly used with other computer graphics techniques to help improve render quality, including Bump Mapping , Specularity , Phong Shading and Shadow Volumes .

Real-time applications, such as computer games, which use modern Graphics Cards will normally implement per-pixel lighting algorithms using Pixel Shaders . Per-pixel lighting is also performed on the CPU in many high-end commercial rendering applications which typically do not render at interactive framerates.
