Abstract:
A method for generating a dot on a display device, the method comprising:receiving a graphics command specifying a dot center for the dot; determining a set of candidate render bins which intersect a neighborhood of the dot center; computing first radial extent values for corners of one of the candidate render bins with respect to the dot center; interpolating estimated radial extent values for sample positions in said one candidate render bin with respect to the dot center based on the first radial extent values of said corners of said one candidate render bin; computing sample values for samples associated with said sample positions, wherein said sample values depend on the estimated radial extent values of the sample positions; and generating pixels based on said sample values, and transmitting the pixels to the display device, wherein the pixels are useable to present the dot on the display device.
