Dynamic modeling and 3-D simulation of water surface
水波现象的光学模型及其三维仿真研究与应用

CG water has been a major research topic for a long time now. Realistically simulating liquids has proven very difficult, due to the inherent complexity of the physical processes involved. Most photorealistic solutions use a form of raytracing and complex differential equations to approximate the optical behaviour and motion dynamics of a water body. Unfortunately, such physically accurate approaches often take many hours of render time per frame, With the advance of programmable 3D hardware, the article discussed methods such as wave physical generation by Perlin function and wave optical model by cubic environment mapping. A lot of the visual properties of water could be approximated by efficient techniques that, even though not physically correct, look convincing to the human eye, and it was pretty appropriate to interactive contexts such as video games, simulation and so on.
