| 摘 要： | 在三维图象重建中采和对象段数据结构，可以使体数据集占用的存储空间显著减少。针对这种数据结构，本文提出一种段切割（ＳＥＧＭＥＮＴ－ＣＵＴ）算法，可以实现对体数据集进行任意复杂形状的切割。这种算法基于一个由切割段表达的切割查找表，避免了对切割边界面的冗余计算，并且直接在涂塑过程中调用。

| Abstract: | In three-dimensional reconstruction,space occupied by the volume data set can be significantly reduced when it is expressed by object-segments.Considering the segment structure of 3D volumetric data,we present a SEGMENT-CUT algorithm for cutting a 3D object,by which any complicated cutting can be implemented.Based on a look-up table expressed by cut-segments,the algorithm can avoid quite a lot of redundant computings for edges of a cutting area,and can be directly called in a rendering process. |
