Abstract

The invention involves: a voxel data reading process (step S ) used to read voxel data on the shape of an object of analysis that is defined by the groups of rectangles of voxels; a boundary determination process used to determine whether each voxel contained in the voxel data, which is read in the voxel data reading process S belongs to a boundary separating the inside from the outside of the shape of the above-mentioned object of analysis; a connected voxel determination process (step S ) used to recursively determine whether the voxel at each level is connected to the other voxel that is determined to belong to the boundary in the boundary determination process; and a voxel redefinition process used to redefine each voxel, at each level in the groups determined in the above-mentioned connected voxel determination process S to the voxel at each level several times wider than the rectangle of a voxel determined to belong to the boundary in the above-mentioned boundary determination process.
