摘要
研究改进了基于镜像原理的反射线追踪算法。将镜像点用树的结点形式作拓扑表示 ,再建立判据去除无效的像点 ,从而极大提高了计算效率。
In this paper, the ray tracing technique with image approach is studied and improved. The images are topologically represented as nodes in a tree, then two improved criteria are founded for filtering the invalid images, thus they can greatly increase the efficiency in ray tracing. Two examples of discovering the validity of these criteria is presented.
