3D POSITION SPECIFICATION DEVICE, 3D POSITION SPECIFICATION METHOD, AND 3D POSITION SPECIFICATION PROGRAM, VOXEL MODELING DEVICE, VOXEL MODELING METHOD, AND VOXEL MODELING PROGRAM

摘要

In a computer (20) with a 3D position specification program installed, when the program starts, an N-th stage Sierpinski carpet (100) is displayed in a 2D coordinate specification region (92) on a display screen (31). When any square region on the Sierpinski carpet (100) is specified, the position in the voxel space composed of 2N x 2N x 2N voxels of one voxel corresponding to the specified square region is extracted by a simple layout calculation even if the depth is not specified. The 3D coordinates in the 3D frame (XYZ) are extracted from the position in the voxel space of the single voxel.
