An Embedded GPU Triangle Rasterization Algorithm for Hardware Implementation

In Embedded GPU, Triangle rasterization is an important factor in determining the performance of graphics processors. Traditional algorithms generate several redundant pixels and cut down the efficiency of GPU. A recursive triangular rasterization algorithm is proposed for tile-based embedded GPU. In addition, the triangular rasterization will cause the aliasing of the graph. The super-sampling anti-aliasing algorithm, RGSS, is used and implemented only by addition and shift operations. The C + + language is used to implement the triangular rasterization and anti-aliasing algorithm. The results show that the rasterization algorithm can complete the rendering of any triangle, and the triangular anti-aliasing effect of RGSS anti-aliasing algorithm is obvious. Anti-aliasing algorithm can significantly improve the rasterization of the anti-aliasing effect and suitable for using in tiled base rendering embedded GPU.
