PROBLEM TO BE SOLVED: To provide a game machine which can diversify a display performance while suppressing an increase in the amount of data.SOLUTION: In a VDP135, geometry calculation including arrangement processing of image data in a world coordinate system is performed, rendering including projection processing onto a projection plane is performed, and thus, drawing data being two-dimensional data are created. When a distortion performance is performed, an object for refraction is arranged so as to overlap a distortion area being a part of a background image, and the object for refraction is deformed by displacing each vertex coordinate constituting the object for deflection in a Z direction. Accordingly, a distorted image is displayed in the distortion area. |
