Abstract
Locations are shaded for use in rendering a computer-generated scene having one or more objects represented by the point cloud. A hierarchy for the point cloud is obtained. The point cloud includes a plurality of points. The hierarchy has a plurality of clusters of points of the point cloud. A location is selected to shade. A first cluster from the plurality of clusters is selected. The first cluster represents a first set of points in the point cloud. An importance weight for the first cluster is determined. A render-quality criterion for the first cluster is determined based on the importance weight. Whether the first cluster meets a render-quality criterion is determined based on a render-quality parameter for the first cluster. In response to the first cluster meeting the quality criterion, the location is shaded based on an indication of light emitted from the first cluster.
