Abstract
In the visual simulation of battlefield geographic environment, the realistic water surface effect can increase the reality of battlefield and enhance the immersion of training personnel, but the fluctuation of water body and the optical characteristics of water surface will also lead to the increase of algorithm complexity and the increase of data quantity, which will affect the fluency of the system. With the improvement of computer graphics hardware performance, in order to reduce the pressure of CPU, many complicated graphics computing has been transferred from CPU to GPU gradually. This chapter’s dynamic surface real-time rendering algorithm will make full use of the programmable characteristics of GPU and powerful computing power, the surface reflection refraction texture sampling, bump mapping, texture movement and other operations are put into the GPU, in order to ensure the surface fidelity, improve the rendering speed.
