ABSTRACT:
Polygon rendering systems for rendering a polygon in an image to be displayed include a rasterizer unit, a first memory buffer, and one or more additional memory buffers. The rasterizer unit is configured to generate one or more low resolution fragments representing a portion of the polygon at a low resolution and one or more high resolution fragments representing a portion of the polygon at one or more higher resolutions. The first memory buffer is configured to store the low resolution fragments as pixels. The first memory buffer is further configured to store data based on the one or more high resolution fragments. The one or more additional memory buffers are configured to store the high resolution fragments as high-resolution sub-pixels. Methods of rendering a polygon in an image to be displayed include generating one or more low resolution fragments that represent a portion of the polygon at a low resolution and one or more high resolution fragments that represent a portion of the polygon at one or more higher resolutions, storing the low resolution fragments as pixels and data based on the one or more high resolution fragments in a first memory buffer, and storing the high resolution fragments as high resolution sub-pixels in one or more additional memory buffers.
