Abstract: A processor shares path tracing data across sampling locations to amortize computations across space and time. The processor maps a group of sampling locations of a frame that are adjacent to each other in world-space to a cell of a hash table. Each cell of the hash table stores a list of reservoirs that are each associated with a ray that intersects the group of sampling locations from world-space. The processor resamples the reservoirs at the hash table by combining and re-using reservoirs across neighboring sampling locations and corresponding sampling locations of the previous frame to select a set of samples mapped to the cell. The processor then performs resampling of the selected set of samples to obtain a representative light sample to determine a value for the cell and renders the frame based on the value of the cell.
