Unbiased Photon Gathering for Light Transport Simulation

Wednesday, 04 November: 11:00 - 12:45

We introduce a novel photon gathering method to achieve unbiased rendering with photon mapping. We also show that our method can be combined with bidirectional path tracing and Metropolis light transport via multiple importance sampling to achieve unbiased rendering with superior performance over alternative algorithms.
