Interactive Global Illumination Effects Using
Deterministically Directed Layered Depth Maps

A layered depth map is an extension of the well-known depth map used in rasterization. Multiple layered depth maps can be used as a coarse scene representation. We develop two global illumination methods which use said scene representation. The first is an interactive ambient occlusion method. The second is an interactive singlebounce indirect lighting method based on photon differentials. All of this is implemented in a rasterization-based pipeline.
