We generalize photon planes to surfaces : a new family of unbiased volumetric density estimators which we combine using multiple importance sampling. To derive our estimators, start with the extended path integral duplicates vertex at end camera and subpaths couples them blurring kernel. make formulation unbiased, however, use delta kernel couple these two points. Unfortunately, sampling resulting singular Monte Carlo is impossible since probability generating contributing light by...
Abstract We derive a class of new Monte Carlo estimators for volumetric time‐of‐flight rendering, generalizing prior work on transient photon points and beams. Conceptually, our method starts with any steady‐state primitive – like plane, parallelepiped, or parallelotope slices it temporal wavefront, producing one dimension lower. show how different unbiased temporally sliced primitives arise by analytically integrating four dimensions within novel extended spatio‐temporal path space...
