Abstract
The present invention is related to rendering computer animated video and/or images generally, and to simulating motion blur efficiently in computer graphics. The present invention includes selecting a plurality of sample locations from which to sample an object scene. If a given sample location overlaps a moving object, existing sample data computed or initialized for the sample location is replicated. This data is then separately updated by sampling the moving object at a plurality of times during the object scene. The replicated data is updated further by subsequently sampling moving and non-moving objects at some or all of the plurality of times. After all of the objects that overlap the sample location have been processed, the replicated data, which may be updated, is combined.
