PROBLEM TO BE SOLVED: To form a complicated image model with a easy procedure by preparing only prescribed vertex data and repeating to transform it. SOLUTION: A data buffer 2 which is memory that temporarily stores the vertex data of a polygon shown on a display device 8, accompanying the progress of a program and a register set function is connected to a CPU 1. A frame buffer 7 is connected to an output side of a rendering processing part 4 which performs coloring, applying, etc., and stores data for one surface which is shown. Three-dimensional coordinate data is specified to each vertex of one polyhedron in three-dimensional virtual space. Coordinate data that corresponds to a two-dimensional plane that is formed by two axes crossing at right angles in three- dimensional coordinate data which is specified to each vertex is parallelly moved, plural polyhedrons are arranged on a two-dimensional plane, plural arranged polyhedrons are separately turned at prescribed angles, and an image model is represented by plural polygons that appear on the surface. |
