摘要
提出一种减少采样点计算的改进光线投射算法进行医学体数据面绘制，以达到缩短体绘制时间的效果。同时给出改进算法的具体实现及关键步骤。最后给出本次改进算法的实验结果。
This paper presents an improved Ray-Casting algorithm which reduces the computation of sampling points in the ray cast, the algorithm is used for surface render in medical volume datasets for few time. Meanwhile the concrete algorithm realization and key step will be shown here. Finally some results with modified algorithm are also given.
