3D动画场景光照渲染算法的效果优化

3D Animation Scene Illumination Rendering Algorithm Optimization Effect

随着计算机动画的不断发展,对于3D动画场景的要求也随之不断提高,一般的光照渲染算法已经无法满足3D动画场景的需求。本文根据一般光照渲染算法在3D动画场景中应用的缺陷,对光照模型以及阴影渲染算法进行了改进,在此基础上得到了混合3D场景光照渲染算法,对Cook-Torrance光照模型进行优化时采用了几何衰减因子算法,对阴影渲染算法进行改进时采用了基于方差阴影的光照阴影渲染算法。仿真试验结果表明,本文提出的基于改进光照模型和阴影渲染的混合3D场景光照渲染算法在实际应用中拥有更好的光照渲染效果。

With the development of computer animation, 3D animation scene for requirements also will continue to increase, the general illumination rendering algorithms have been unable to meet the demand of 3D animation scene. This paper based on the general illumination rendering algorithm in 3D animation application, put forward the improvement model of light and shadow rendering of mixed 3D scene rendering algorithm based on, first using the geometric attenuation factor on Cook-Torrance illumination model is optimized, and then the shadow rendering algorithm of sawtooth and the edge of the shadow is optimized. The simulation results show that, based on the improved illumination model and rendering of mixed 3D scene illumination rendering algorithm has better in the practical application of light rendering effect.
