PURPOSE:To reconstitute a source three-dimensional object in short processing time with high accuracy. CONSTITUTION:In the case of calculating the density value of an arbitrary point P on a three-dimensional space, six points on a lattice plane image composed of six slice images surrounding the arbitrary point P are cared, first of all, the density value at the point P in respective directions (x), (y) and (z) is calculated from density values at the six points cared on the lattice plane image, further, intervals Dx, Dy and Dz of slice images in the respective directions (x), (y) and (z) are considered for those three density values, the density at the point P is finally calculated, the points with the equal density value calculated by applying this processing are linked, and the smooth three- dimensional object is reconstituted. |
