ABSTRACT:
Methods and apparatus for rendering graphics primitives to display devices in a computer graphics frame buffer system are disclosed. The methods provide an array of addressable video random access memory (VRAM) chips associated to form the graphics frame buffer. The VRAMs in the frame buffer are addressed with coordinate pixel locations on the display device corresponding to locations of the graphics primitives on the display device. The frame buffer is accessed with a graphics rendered according to arbitrarily shaped tiles containing pixels such that the pixels within the tiles have potentially different VRAM addresses.
