In this paper, the Bump Mapping which was created by Blinn in 1978 is introduced. Through the comparison of the Phong Shading with the Gouraud shading, this paper shows that the Bump Mapping is also the expansion of the shading technology.

 
  • 介绍了Blinn于1978年提出的几何凹凸纹理映射技术(Bump Mapping)的实现原理,通过比较Phong shading(法向量插值明暗处理)和Gouraud shading(光亮度插值明暗处理)方法的不同,说明了Bump Mapping是法向量光亮度插值方法的一种扩展。
