摘要
针对当前体绘制存在的软件加速算法,将其分为空间剖分技术、光线相关、物空间相关和基于图像绘制技术等四类,分别介绍其算法基本内容。最后利用MIN-MAX八叉树加速算法设计一个直接体绘制系统。
The purpose of this paper is to present a survey of recent publication concerning accelerating direct volume rendering by software.These techniques are described in four profiles:space dividing,ray coherence,object coherence and image based rendering.Finally,a direct volume rendering system is designed based on min-max octree.
