Abstract
A method and system for providing a graphics processor is disclosed. The method and system include providing a transformation processor, providing a rasterizer coupled to the transformation processor, and providing an interpolator coupled to the rasterizer. The transformation processor is for producing a set of transformed data according to a set of instructions from a set of raw data. The set of raw data describes at least one three-dimensional object within a bounded space extending from a display screen. The rasterizer is for identifying portions of the transformed data mapping a pre-defined area of the display screen in parallel and for sequentially rendering the identified portions of the transformed data in a pre-determined refresh order. The refresh order is the order that screen data is provided to the display screen to generate a screen image. The rasterizer further includes processor array. The processor array includes a plurality of primitive processors. Each of the plurality of primitive processors processes a corresponding portion of the transformed data and identifies whether the corresponding portion of the transformed data that intersects a selected area of the display screen. The interpolator is for determining a visible portion of the identified portions associated with selected area and characterizing the selected area according to transformed data associated with the visible portion.
