Abstract:
Shadows are an important part of a visualization and give the viewer supplemental details about the appearance of objects. In real-time rendering, shadow mapping [Williams 1978] is a popular approach to compute shadows. However, a shadow map must be computed for each light and thus, the memory and the computation time increases with the number of lights.
