Shadow map algorithms are commonly used in shadow generation due to their simplicity and independence of scene complexity. Three aspects are considered in constructing appropriate shadow maps: the number of shadow maps, parameterization of shadow maps and the content of shadow maps. Following these three aspects, this paper will study most of the shadow map algorithms currently proposed, discuss their advantages and drawbacks and their application areas.
