This paper describes a real-time shadow generation algorithm for polygonal environments illuminated by movable point light sources. The main goal is to quickly reduce the number o...
This paper presents an algorithm for shadow calculation in dynamic polyhedral scenes illuminated by point light sources. It is based on a modi cation of Shadow Volume Binary Space...
Soft shadows and penumbra regions generated by extended light sources such as linear and area lights are visual effects that significantly contribute to the realism of a scene. In ...

We present a novel algorithm for rendering physically-based soft shadows in complex scenes. Instead of casting shadow rays, we place both the points to be shaded and the samples o...
We present a novel method for rendering shadow volumes. The core idea of the method is to locally choose between Z-pass and Z-fail algorithms on a per-tile basis. The choice is ma...
