A more efficient triangle rasterization algorithm implemented in FPGA

摘要

3D graphics hardware acceleration has become more and more important in mobile devices. In the paper, we review some triangle rasterization algorithm previously. On that basis, we propose a novel triangle rasterization algorithm — midpoint traversal, which reduce the number of traversal points and improve the efficiency of graphic acceleration. At last, we use FPGA to implement the algorithm, drawing a conclusion: in the equality resource, compared with others triangle rasterization algorithm based edge function, the midpoint traversal can improve the efficiency.
