Abstract
A method and system for rendering a graphic object that decouples shading from rasterization is disclosed. The method includes selecting a set of points of a graphic object for shading. At least one shading parameter is determined for application to the selected set of points of the graphic object. The selected points are shaded using the shading parameter image to produce a shaded graphic object image via a graphic processor at a first frequency relative to the frame rate. The shaded graphic object image is rasterized into a frame image in parallel at a second frequency relative to the frame rate. Multiple processors may be used for the shading and rasterization.
