[Graphics]Shadow Mapping & Shadow Volume
Keywords: Graphics, Rendering, Shadow Mapping
Shadow mapping or
shadowing projection is a process by which shadows are added to 3D computer graphics. This concept was introduced by
Lance Williams in 1978, in a paper entitled “Casting curved shadows on curved surfaces.” Since then, it has been used both in pre-rendered and realtime scenes in many console and PC games.
Shadows are created by testing whether a pixel is visible from the light source, by comparing the pixel to a z-buffer or depth image of the light source’s view, stored in the form of a texture.
