A Low Hardware Cost 2D Vector Graphic Rendering Algorithm for Supersampling Antialiasing

An edge-flag rendering algorithm for supersampling antialiasing with low hardware cost is presented. The proposed algorithm works differently from the common rendering algorithm, using only one counter per pixel instead of one counter per sample point. Compared to the common rendering algorithm, the proposed one uses about 83% less memory capacity for a scanline-sized buffer and saves nearly 65% of the computation work performed in implementing the 8-Queen supersampling algorithm on XVGA panels. Experiments show that the proposed algorithm performs antialiasing with fairly good quality as well.
