Using Perception-Based Filtering to Hide Shadow Artifacts

  title={Using Perception-Based Filtering to Hide Shadow Artifacts},
  author={Felix Kreuzer and Michael Wimmer},
Shadows are an indispensable aid for understanding spatial relations of objects in natural scenes, which is why they are very important for real-time rendering applications. Combining filtering techniques with shadow mapping is a common tool to simulate visually-pleasing shadows in interactive applications. A positive effect of such approaches is that the filtering blurs aliasing artifacts caused by sampling the discretized geometric data stored in the shadow map, thereby improving the visual… CONTINUE READING
