PURPOSE: To cope with such a case as to plot many spheres and pipings at a high speed. CONSTITUTION: This device is provided with a texture memory 27 for storing the color information on the surface of an object and the depth information on the object, a read means for reading the chrominance information on the surface of the object and the depth information required for plotting the object in response to the reception of a command for plotting the object stored in the memory corresponding to specified size and position, and the chrominance information and the depth information when it is required. the processing means of magnification and reduction, etc., for performing magnification, reduction and depth change processing to the chrominance information on the surface of the object and the depth information on the object, a color processing for executing a processing for the chrominance information of the surface of the object for which the processing of the magnification and the reduction, etc., is performed and a hidden surface processing means for performing a hidden surface elimination processing for the surface of the object to be plotted from the chrominance information on the surface of the object, the depth information on the abject and the position specified by the command. |
