Dynamic Water Surface Simulation Based on Secondary Reflection Mapping

Abstract

Abstract: In order to improve the effects of dynamic water surface simulation, a method was proposed which utilized 3D mesh modeling water surface and was optimized by projective grid method; A mirror image of the subject above the water was generated which was called the first reflection map; then the simplified Navier-Stokes equation was enforced onto the first texture mapping. The reflection and refraction was calculated to form a secondary reflection map with respect to the perspective mapping coordiante; Perspective texture mapping was enforced to water surface to achieve fast simulated water surface. Experimental test shows that the approach can simulate the dynamic water surface fastly with high quality. This method is suitable for precise observation of water surface and more than 30FPS frame rate can be achieved.

Key words: Navier-Stokes, water surface simulation, reflection, refraction, reflection mapping
