| 摘 要： | 本文讨论了规则体数据场的体绘制算法,将光线投射体绘制算法看作是对体数据立方体投影多边形的填充,减少了投射光线的数目。将Bresenham画线算法推广到三维空间,减少了光线投射算法的计算时间。本算法已应用于我所开发的三维核磁共振图像分析系统中,效果较好。

| Abstract: | This paper discusses the volume rendering algorithm in regular data field. By looking rendering as a process of filling in projective polygon the amount of casting ray has been reduced. By extending Bresenham algorithm into three - dimension, this algorithm reduces time of ray - casting calculation. This algorithm has been applied to 3D NMR Image Analytical System of our institute and proved efficient. |
