PROBLEM TO BE SOLVED: To optionally deform a 3D polygonal model in a state where the smoothness of its surface is kept, following a user's operation in real time by use of a computer of consumer level. SOLUTION: The image processing program divides each polygon to be divided which consists of three edges to be divided as polygons 1, 2, 3, 5, 6, and 7, as shown in Fig. 14, to four pieces on the basis of the calculated dividing positions of edges to be divided, and halves a polygon which is not the polygon to be divided but contains only one edge to be divided as polygon 4.
