| Abstract: | Modern PC graphic cards manufacturers claim their cards support Phong shading, however, the existing Phong shading model is only suitable for the case where the light is directional and fixed. We present a new Phong shading method, which can be applied to any kinds of light sources and movable lights. This method generates high precision Phong shading result by transferring the lighting computation from eye space to local triangle space, and uses to the full extent of acceleration functions supported by modern graphic cards, so it produces real-time Phong shading with high quality. Compared with previous methods, the presented one is more general. |
