Abstract:
Shadow volumes are a popular technique for generating shadows [Crow 1977]. They are being used more and more in games such as Doom 3. The technique involves rendering shadow volumes to the stencil buffer. Since the size and number of shadow volumes are of- ten quite large, the rendering can become fill-bound. We present an acceleration technique that reduces the size and number of shadow volumes when possible, thereby reducing rasterization time.
