Instant caching for interactive global illumination

The computation of realistic physically-based lighting on a single desktop machine is computationally expensive and various methods have proposed exploiting spatial coherence when calculating the lighting at a point such that calculations from other previously computed points can be used. However, this is done at each frame. This paper presents new temporal coherence algorithms that re-use previously computed information from other frames, obtaining significant speedup. This work led to an industrial mathematics sKTP with civil engineering firm Arup (steve.walker@arup.com) to compute high-fidelity renderings for scenarios with dynamic natural lighting.
