摘要

PROBLEM TO BE SOLVED: To prevent that quality of a structure of an internal organ or a tissue of a model is greatly depends on an arrangement position or the number of control lattice points of free-form deformation (FFD) algorithm, and to smoothly deform an attitude model while holding a bodily shape, the internal tissue, and the internal organ.;SOLUTION: The surface of a subject is divided into three-dimensional polygonal lattices (voxels), polygonal lattice data about each divided voxel are stored in a first storage part as surface voxel coordinates, mesh deformation is applied to each piece of voxel data related to the surface voxel coordinates read from the first storage part, the surface voxel coordinates in a state in which an attitude of the subject is deformed are calculated, the calculated surface voxel coordinates after the attitude deformation are stored in a second storage part as attitude deformation surface voxel coordinates, the inside of the subject is divided into the voxels, polygonal lattice data about each divided voxel are set as internal voxel coordinates, and internal voxel coordinates after interpolation are obtained by interpolating each piece of data related to the internal voxel coordinates by use of interpolation algorithm.;COPYRIGHT: (C)2011,JPO&INPIT
