摘　　要：背面剔除在图形流水线中提前剔除不可见三角形,避免不必要的扫描转换和染色。本文从硬件实现角度,针对经典背面剔除算法在硬件实现中需要较多硬件资源的问题,提出一种适合硬件实现的背面剔除新算法,理论上证明了该算法的正确性。仿真和综合结果表明该算法的实现可以减少硬件资源、提高处理效率。The function of the backface culling is to exclude invisible triangles in advance to avoid unnecessary rasterizing and rendering in graphics pipeline. This article focused on the problems a- bout hardware resources and proposed a new algorithm for the backface bulling. The correctness of the algorithm was proved theoretically. The simulation results showed that the new algorithm can save hardware resources and improve the processing efficiency.
