ABSTRACT:
A method, system, and computer-readable storage medium are disclosed for performing anti-aliasing operations on lines using a graphics processing unit (GPU). Input comprising a plurality of vertices may be received at a GPU. The plurality of vertices may represent one or more line segments. One or more anti-aliased line segments may be generated based on the input. In generating the one or more anti-aliased line segments, the intensity of a first edge and a second edge of each line segment may be modified based on application of an anti-aliasing function. A maximum intensity of a central portion may be maintained for at least one of the line segments, wherein the central portion is between the two edges and is greater than one pixel in thickness.
