PROBLEM TO BE SOLVED: To faithfully display details of a binary object surface by adjusting the position of a surface node to change the length of a link between adjacent nodes, relieving a net and rendering an image based on the relieved net. SOLUTION: A surface cube in extraction binary data is detected (16), a surface node is arranged at the center of the detected surface cube and a link is produced between it and an adjacent surface node (18). And, a net node position is adjusted so as to reduce energy in a net, the energy is minimized, the length of the link is recursively reduced under a constraint condition that the net node must stay within the original surface cube (22 to 26) and a surface net is relieved (20). The surface net is made a triangle based on the relieved net at the time of triangular rendering 36, the model is decimated (38) and a polygon model is subjected to rendering (40). |
