截面的相关体元搜索算法及应用

The Algorithm of Searching Correlate Cubes of an Arbitrary Section

实现了任意平面和立方体网格相截，简捷地得到了截面和立方体网格的所有交点，在此基础上，提出了相关体元搜索算法，该算法能够快速地搜索出所有与截面相交的体元，减少了所有体元和截面进行求交判断的计算量．在科学计算可视化中得到很好地应用．

The intersection of an arbitrary plane and some cube network is realized. And all the points of intersection are got briefly. On the basis of this, a new algorithm of searching correlate cubes is presented. This algorithm can search out all the cubes which intersect the section accurately. It reduces the amount of calculation in judging whether the cubes intersect the section. This algorithm is used very well in visualization in scientific computing. [
