A design of a 3D graphics rasterizer with a culling and clipping

In this paper, we designed 3D graphics rasterizer with a culling and clipping for the efficient 3D graphics accelerator. The proposed rasterizer is implemented for the mobile system and process frustum culling, back face culling, Y-axis clipping and X-axis clipping. The rasterzier consists of triangle setup, edge walk and span process unit. Each unit of rasterzier is designed with a culling and clipping. It supports goraud shading with 16-bit depth values and 16-bit color values. The estimated performance of proposed rasterizer is 52M pixels per second.
