基于GPU的海面场景动态光影渲染研究
Research on Dynamic Lighting and Shadow Rendering of Ocean Scene Based on GPU
摘要
Abstract
Aiming at the shortage of virtual reality lighting and shadow rendering effect of ocean scene,realize the multi-time dynamic lighting simulation of ocean scene including the virtual ocean scene building and dynamic sea surface lighting-shadow rendering. Using the GPU programmable rendering pipeline and CG programming language,the research applies OpenGL illumination model,ShadowMap algorithm and PCF algorithm to the scene for simulating the lighting-shadow scene under multi-lights in 24 hours. The experimental re-sults show that,the rendering of the sea shadow effect is real,interactive and dynamic,so it can be widely used in the field of ocean virtu-al reality.关键词
