Next Event Estimation++: Visibility Mapping for Efficient Light Transport Simulation

Monte‐Carlo rendering requires determining the visibility between scene points as the most common and compute intense operation to establish paths between camera and light source. Unfortunately, many tests reveal occlusions and the corresponding paths do not contribute to the final image. In this wo...
