Abstract
One embodiment of the present invention includes techniques for pre-computing ambient shadowing parameters for a computer-generated scene. A processing unit retrieves a reference object associated with the computer-generated scene and comprising a plurality of vertices. For each vertex in the plurality of vertices, the processing unit computes a local ambient shadowing parameter, and stores the local ambient shadowing parameter in a memory. For each instance of the reference object included in the computer-generated scene, the processing unit computes a first global ambient shadowing parameter based on the position of the instance within the computer-generated scene, and stores the first global ambient shadowing parameter in the memory. One advantage of the disclosed embodiments is that ambient obscurance is applied to instance objects in a scene in real time while reducing memory space dedicated to storing the AO parameters.
