A 3D graphics shading module is presented to provide flat shading, Gouraud shading and Phong Shading in this paper. A fast Phong shading algorithm, H-test, is applied to this design. The features of this design is to realize the lighting model and interpolation by logarithm space divider, and logarithm space exponent. The post layout simulation results show that the system can operate up to clock rate of 68.9 MHz. This implies that pixel rate up to 34.5 M pixels per second and 222 K 10×10, Gouraud shaded polygon rate per second and 172 K Phong shaded polygon can be achieved.
