一种云场景的实时渲染方法
Method of real-time clouds rendering
摘要
Abstract
The simulation of realistic cloud scene is discussed,a method of real-time cloud rendering is designed. Cloud concentration diagram is generated based on Perlin noise. Using Phong illumination model and single-scattering model,the reflected light and transmitted light are respectively calculated to improve the traditional methods that cannot truely reflect the sun light from different directions, and the dynamic cloud scene rendering is realized at different times.By the using of GPU-based Bumping Texture algorithm and Render-to-Texture technology,the rendering efficiency of the cloud scene is greatly improved. Experimental results further show that the method both satisfy the realistic and real-time needs.关键词
