Description
  • Standard online occlusion culling is able to vastly improve the rasterization performance of walkthrough applications by identifying large parts of the scene as invisible from the camera and rendering only the visible geometry. However, it is of little use for the acceleration of shadow map generation, so that typically a high percentage of the geometry will be visible when rendering shadow maps. Our algorithm remedies this situation by quickly detecting and culling the geometry that does not contribute to the shadow in the final image. The main idea is to use camera-view visibility information to create a mask of potential shadow receivers in the light view, which restricts the areas where shadow casters have to be rendered.
