一种实时体切割绘制的光线分段预处理方法
Pretreatment of rays Method for Real-Time Volume Clipping
针对传统图形绘制算法速度慢，质量不高的缺点，本文提出了一种快速的基于光线投射法的体切割预处理方法。通过外接球面和进行分段的光线投射预处理，在保证绘制质量的同时，实现了实时体切割。实验结果表明，本方法对于医学可视化应用，在使用规则体数据时，有令人满意的结果。
o overcome the disadvantages of the traditional volume clipping algorithm, this paper proposes a fast volume clipping method based on ray-casting. This method can realize real-time volume clipping by combining the methods of external sphere and pretreatment of rays. At the same time, the quality of rendering is still good. The method aims at regular volumetric data. Therefore, it is applicable in medical visualization.
