PROBLEM TO BE SOLVED: To provide a three-dimensional(3D) image constituting device capable of reproducing image data with fidelity in a short time. SOLUTION: Concerning an algorithm for extracting surface pixels so as to plot the surface of medical image data with dots while using OpenGL and for calculating the inclination of the surface of a correspondent pixel, when plotting the surface of a 3D object, the patch of a polygon corresponding to the pixels is not plotted but one dot is plotted corresponding to one pixel. By plotting dots corresponding to each of pixels, a conventional gap or unnatural ruggedness does not occur. |
