BOUNDARY DATA INSIDE/OUTSIDE JUDGMENT METHOD AND PROGRAM THEREOF

摘要

A method for determining insides and outsides of boundaries includes an external data input step of inputting external data constituted by boundary data of objects, a cell division step of dividing the external data into rectangular parallelepiped cells having boundary planes orthogonal to each other, a cell classification step of classifying the cells into a boundary cell that includes the boundary data and a non-boundary cell that does not include the boundary data, and a space classification step of classifying the non-boundary cells into a plurality of spaces that are partitioned by the boundary cells.
