基于体单元的光线跟踪算法

论述了体光线跟踪的基本原理及算法实现。将物体划分为若干个体单元，光线若与体单元相交，则经过体单元反射或透射后继续跟踪，对体单元采用体可视化技术进行显像，生成真实感图形。体光线跟踪算法可生成复杂景物的高质量图形，较光线跟踪算法的存储信息量小，而且可以体现物体深层的研究。

Ray Tracing Algorithm Based on Voxel

This article primarily introduce the basic principle of volume ray tracing algorithm and its realization. The object is first devided as a number of voxels.If ray hands over with voxel,tracing ray will be reflected or transmitted by voxel.Voxels are viewed by volume visualzation technology.Then real graphic is emerged. The volume ray tracing algorithm can engender the complex and high scenery, can be smaller than the ray traceing algorithm at the information's store, and can embody the research of the deep layer of object.
