Abstract
A vertex accumulation buffer for improved three-dimensional graphical processing is disclosed. The accumulation buffer may include two individual buffers (buffers A and B) that each comprise a plurality of individual storage locations that are each configured to store vertex parameter values such as XYZ values, normal values, color information, and alpha information. The individual buffers serve to double buffer the vertex parameter values stored in the accumulation buffer. The storage locations may be written to on an individual basis without overwriting the other storage locations in the buffer.
