Abstract
We describe a map-based shading unit for volumetric raycasting architectures. This is a critical part of volume rendering accelerators with respect to image quality, achievable performance, and resource consumption. The typical problem with map-based shaders is that highlights might not be rendered correctly on highly glossy surfaces due to the limited resolution of the maps. As a solution to this problem we introduce the use of detail light maps.
