DescriptionWe introduce a real-time, ray-traced, ambient occlusion technique in which noise is filtered in world space. Using extended spatial hashing for efficient storage, multiresolution AO evaluation and ad-hoc filtering, we compute ambient occlusion in a few milliseconds in CAD scenes, comprising thousands of instances and hundreds of millions of polygons.
