METHOD AND PROGRAM FOR CONVERTING BOUNDARY DATA INTO IN-CELL SHAPE

摘要

A method for converting boundary data into in-cell shape includes a division step (A) of dividing external data (12) consisting of boundary data of an object into cells (13) of orthogonal lattice, a cutting point decision step (B) of deciding the intersection point of the boundary data and the cell edge to be a cell edge cutting point, a boundary decision step (C) of deciding the boundary connecting the obtained cell edge cutting points to be in-cell shape data, a cell division step (D) of dividing the divided cells into non-boundary cells (13a) not containing a boundary plane and boundary cells (13b) containing a boundary plane, and a boundary cell data division step (E) of dividing the cell data constituting the boundary cells into inner cell data located inside the in-cell shape data and outer cell data located outside the in-cell shape data.
