摘要
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。在小转角(≤45°)情况下,可使显示速度提高一个数量级以上。采用该方法,可望在微机上实现三维体数据的交互式显示。
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. Within small rotating angle (less than 45degrees),the display speed can be a dozen times that of conventional algorithm. It ispossible to realize interactive surface rendering on microcomputer by applying the presented method.
