WebA shader is a small program that is executed on the graphics card. It provides the programmer with more control over the drawing process and in a more flexible and simple way than using the fixed set of states and operations provided by OpenGL. With this additional flexibility, shaders are used to create effects that would be too complicated ... http://duoduokou.com/csharp/37722994462387354608.html howling eye
