| Abstract | We present a new method of precomputing high-quality soft shadows that can be cast on dynamic objects added to the scene. We store all visibility events by efficiently merging the visibility computed from many shadow maps into an extended deep shadow map (DSM) structure. The resulting structure effectively captures the changes of attenuation in each DSM pixel, and therefore constitutes an accurate representation of light attenuation from extended light sources of all sizes. We show how it can be compressed and how modern programmable graphics hardware technology can be used to cast real-time complex soft shadows on static scenes and on animated objects within those scenes. |
