    Abstract: Antialiasing method and apparatus for video applications. A method for antialiasing a video graphic. First, the processor renders the pixels and, during the step of rendering, determines if an edge pixel of a polygon is being rendered. If so, a sample point is defined within each pixel and a determination made if the sample point lies within the polygon or outside of the polygon. If the sample point lies within the polygon, the color of the edge pixel is set to the color of the polygon. If the sample point lies outside of the polygon, the color of the edge pixel is set to the color of the background. The percentage of the pixel that lies in the space associated with the sampling point is then calculated. The color of the pixel is stored in a frame buffer in association with the percent value that lies in the space associated with the sample point and in association with an indication that the sample point lies within the polygon or outside of the polygon.
