ABSTRACT:
A method and apparatus for improving bandwidth for depth information communication in a computer graphics system. In operation, a decoder checks a type table associated with a collection of pixels in a memory unit in response to a request for depth information with respect to the collection of pixels. If the type table indicates that the depth information with respect to the collection of pixels has been encoded previously, the decoder computes depth values corresponding to the collection of pixels for each visible polygon in accordance with respective sets of plane parameters in a parameter record associated with a plane pattern, and reconstructs the depth information from the depth values for each visible polygon in accordance with the plane pattern. When the collection of pixels is modified by a new polygon, an encoder updates the plane pattern, the parameter record, and the type table in the memory unit.
