Study of Water Surface Scattering Model Based on Unity3D Shader

摘要

Aiming at the problem that scattering effect can not be achieved in traditional shader rendering, a water surface scattering model based on Unity3D Shader is proposed. Firstly, the scattered light is simulated and calculated. Secondly, the logical structure of the shader model is constructed. The vertex program function including the calculation of scattered light is designed. The function structure containing the concept of time is introduced into the static water model to develop the dynamic water surface scattering shader. Finally, taking Hainan seascape communication experience platform as an example, we verify the effect of the shader model.
