ABSTRACT:
An image processing apparatus used with a display device having a number of pixels arranged in a predetermined form includes a surface model creating processor operable to create a surface model which is defined by a number of polygons with each polygon having a surface number and a parameter. A frame memory has addresses corresponding to the pixels of the display device, and is operable to store a surface number at each address to represent the surface model in terms of surface numbers. A polygon parameter memory is operable to store the parameter of each polygon, and a texture data memory is operable to store texture data for each polygon at addresses arranged in a predetermined form. A calculator is operable to calculate, based on a designated address of the first memory and the parameter of the polygon corresponding to the surface number at the designated address, an address of the third memory storing texture data corresponding to the designated address. The calculator is also operable to generate and send an address signal indicative of the calculated address to the third memory so as to transmit the texture data stored at the calculated address to the display device.
