A game machine for high-speed execution of iterated transformation decoding based on a drawing command or data loaded from a recording medium. The drawing command, fractal transformation parameters or data loaded from a recording medium 24 are stored in a main memory 21. A drawing texture, expanded on a VRAM 23 in a graphics processing unit 22, is iteratively transformation decoded in accordance with the drawing command or the fractal transformation parameters transferred under control of the CPU 20. The generated texture is displayed as a picture on a CRT 32 of the graphics processing unit. This realizes high-speed iterated transformation decoding of the texture and a restored picture of high picture quality while realizing iterated transformation decoding with a significantly reduced calculation volume.
