Abstract
High fidelity arcs are produced using a set of interconnected trapezoids, which are transmitted in a highly efficient triangle mesh to a graphics rendering device. Perspective correction capabilities of a graphics engine are used to map a small rectangular texture patch onto the trapezoids, such that the circle appears completely smooth. Anti-aliasing line profiles are applied such that super-sampling is only required in a single dimension.
