shader warter 水反射折射的计算 One of the classic challenges of real-time computer graphics is to generate realistic looking water. Because water can look very different depending on the context of the scene, it is important to define a few different categories of water effects. For example, techniques used to render ocean water may not produce realistic looking puddle water. With this in mind, the shaders presented in this chapter will focus on highly realistic per-pixel lighting effects used to render real-time lake water. Unlike ocean water, lake water does not have large rolling swells. Instead, the surface geometry consists of high frequency, non-uniform perturbations that give the surface a subtle choppiness resulting in slightly distorted reflections and refractions. Because of these surface characteristics, shallow water reflections and refractions as shown in Figure 1 can be reasonably approximated with planar reflections and renderable textures.
