光线投影算法将光线穿过数据场中的体元，采样得到相关象素的颜色， 形成可视图。
Ray-casting algorithm is that ray passes volume cell of data field, sampling relative pels color to form video image.
光线投射算法显示速度较慢，本文在深入分析其原因的基础上，提出利用投影角度相关信息来提高旋转显示的速度。
The rendering speed of conventional ray-casting algorithm is very slow. Anew approach is presented here to notably improve the display speed using rotate-relative messages for further processing.
