A cycle formation step classifies the rectangular parallelepiped cells into a boundary cell having the cutting point and a nonboundary cell having no cutting point, acquiring a cutting segment between a cell surface and boundary data for each boundary cell, and forming a cutting segment cycle closed by connecting the cutting points and the cutting segments alternately in sequence. A cycle internal division step divides the inside of the cutting segment cycle into cycle inner triangles sharing an adjacent side, for each boundary cell. A simplification step of unifying a plurality of cutting points on each edge, and registering the cycle inner triangles in the cell, for each boundary cell.

The method includes an oct-tree division step of dividing external data including boundary data of a target object into rectangular parallelepiped cells having boundary planes orthogonal to each other by oct-tree division. The method further includes a cell classification step of classifying each of the cells into an internal cell positioned inside or outside the target object or a boundary cell including the boundary data, and a cut point determination step of determining cut points of edges of the boundary cell based on the boundary data. The method further includes a boundary surface determination step of connecting cut points to form a polygon, and determining the polygon as the cell internal data when the number of the determined cut points is no fewer than 3 and no more than 12.

摘要： A coordinate system R is set in which P0 is a coordinate origin, P0P1 conforms to a first U axis to have a unit length, P0P2 conforms to a second V axis to have a unit length, and P0P1×P0P2 is a unit vector conforming to a third N axis. A transforming matrix M that transforms an ordinary coordinate system into the coordinate system R and the u-, v- and n-coordinate values of the both ends of the line segment are calculated. It is determined whether or not the line segment intersects with the triangle, on the basis of the u-, v- and n-coordinate values. The u-, and v-coordinate values of the intersection point are calculated. It is determined whether or not the intersection point is positioned inside the triangle, on the basis of the u-, and v-coordinate values of the intersection point.
