本文链接地址: Lesson 47 CG Vertex Shader
Using vertex and fragment (or pixel) shaders to do some rendering dirty work can have numerous benefits. The most obvious is the movement of some of the graphics related CPU load off the CPU and onto the GPU. Cg provides a (reasonably) simple language for writing very powerful shaders. This tutorial has multiple aims. The first is to present a simple vertex shader that actually does something, without introducing unnecessary lighting etc… The second is to provide the basic mechanism for running the vertex shader with visible results using OpenGL. As such, it is aimed at the beginner interested in Cg who has a little experience in OpenGL. This tutorial was written by Owen Bourne.
