A Significance Cache for Accelerating Global Illumination

Rendering certain high-fidelity lighting scenarios can be considered highly complex, particular for hard to find light paths, for example light entering from a shaft. The significance cache constructs and stores important directions as the computation ensues; it then is analytically sampled to calculate important paths that accelerate the computation. Results showed a significant improvement over traditional methods. Such scenarios are common in architectural design and this work led to a £125k EPSRC grant EP/I038780/1 with the civil engineering firm Arup (steve.walker@arup.com) and University of Warwick spin-out goHDR (www.gohdr.com) to extend this work for such complex scenes in the temporal domain.
