Abstract:
1. An apparatus for use in a computer graphics system, comprising: a plurality of depth buffers for storing depth data, wherein at least one of the plurality of depth buffers is configured to provide depth data for a group of pixels, wherein at least one other of the plurality of depth buffers is configured to provide depth data for each pixel of the group; a plurality of stencil buffers, the stencil buffers configured to store stencil shadow volume data, wherein at least one of the plurality of stencil buffers is configured to provide stencil shadow volume data for the group of pixels; wherein at least one other of the plurality of stencil buffers is configured to store stencil shadow volume data for each pixel of the group; and control logic for controlling the plurality of stencil buffers and the plurality of depth buffers, wherein the stencil shadow volume data is generated and stored.
