G-buffer compression

Abstract

A method for geometry buffer compression includes generating, based on geometry information of pixels in a frame, compressed geometry information for buffering in a geometry buffer (G-buffer). The compressed geometry information includes first texture component for first pixels and omits the first texture component for at least a second pixel. The second pixel has one or more neighboring pixels in the first pixels. Further, the method includes accessing the geometry buffer to obtain the compressed geometry information, and generating reconstructed geometry information of the pixels based on the compressed geometry information. The reconstructed geometry information includes the first texture component for the second pixel that is reconstructed based on the first texture component of the one or more neighboring pixels in the first pixels. Then, the method includes performing a rendering to generate an image according to the reconstructed geometry information of the pixels.
