使用vc6环境，基于ogl和cg实现的displacement map的效果。需要可编程管线的显卡支持。-vc6 use of the environment, based on t cg and the displacement map to achieve results. The need for programmable graphics pipeline support.

GPU Gems is a compilation of articles covering practical real-time graphics techniques arising from the research and practice of cutting-edge developers. It focuses on the programmable graphics pipeline available in todays graphics processing units (

OpenGL着色语言（GLSL――OpenGL Shading Language）是用来在OpenGL中着色编程的语言，也即开发人员写的短小的自定义程序，他们是在图形卡的GPU （Graphic Processor Unit图形处理单元）上执行的，代替了固定的渲染管线的一部分-The recent trend in graphics hardware has been to replace fixed functionality with programmability in areas tha
