PURPOSE: To provide the image display processor with the modeling buffer which can reduce the capacity of the modeling buffer part and can perform a modeling process for a more complicated shape than before. CONSTITUTION: A main CPU 2 obtains a visual field range and a visual field direction from input data, reads only polygon data on a part put in the visual field of a part to be displayed out of a ROM 1, and stores it in data bank RAMs (0) and (1) alternately. A DISP 4 processes data read out of a data bank RAM 3 by computer graphics(CG) and writes the processed data in a frame buffer 5. The DSP 4 is lightened in processing load, so it can performs other polygon processing and process a complicated process. |
