Dynamic Diffuse Global Illumination

We present our implementation of a recent real-time global illumination method based on irradiance fields, which uses ray tracing to approximate multiple bounces of light transmission in a virtual scene. Then we present our method, which repurposes the global illumination algorithm to compute global ambient occlusion in real time. We also present our extensions to the algorithm, such as field cascades and geometry-aware probe culling. Lastly, we discuss possible further extensions, such as adaptive ray generation and probe placement.
