The present invention is directed to a method and apparatus for reducing the frame buffer size in a 3D graphics system. According to an exemplary aspect of the present invention, sorting and limiting the polygons that get processed at a given time may reduce the size of the frame buffer required in a graphics system. This may allow the system to process only those polygons that fall in one section of the screen. As a result, the system may not need to double buffer the whole screen. In a preferred embodiment, the location of the screen that gets processed may be arbitrary but should be preferably chosen so it is easy to sort the polygons and time-manage the process as the system needs to know when to swap from one location to another.
