In this paper, we proposed an effective visibility test architecture with improving the mid-texturing architecture. The proposed architecture uses the property of fragments that the visibility of adjacent fragments is identical, and performs only a single visibility test per fragment. To compare with the mid-texturing architecture, simulation results show that the bandwidth requirements and the cell area of the depth cache in the proposed architecture are reduce by 25% and 34%, respectively, in exchange for less than 5% performance decline.
