摘要： A data input means inputs boundary data of an object to a computer, a data converting means converts the boundary data into a triangle patch having a phase, an associating means divides a space into rectangular parallelepiped cells having boundary planes intersecting perpendicularly and associates the cell with a triangle to be included in the cell, a dividing/arranging means divides a triangle patch having a phase and floating in the space at cell faces and keeps all triangles arranged within and on the boundaries of cells, a ridge line integrating means integrates ridges that do not alter the phase, a cell assigning means assigns each triangle and its vertex to a cell with reference to index data of the vertex, and a labeling means sets an attribute value of each cell.
摘要翻译：数据输入装置将对象的边界数据输入到计算机，数据转换装置将边界数据转换为具有相位的三角形块，关联装置将空间分成具有垂直相交的边界平面的长方体，并将该单元与要包括在单元格中的三角形，分割/排列装置将具有相位的三角形补片分隔成在单元面处的空间中，并且将所有三角形排列在单元的边界内和边界上，脊线积分装置将脊不改变相位，单元分配装置参考顶点的索引数据将每个三角形及其顶点分配给单元，并且标记装置设置每个单元的属性值。
