The optimal value of the steps is first derived when rastrerizing parametric curves. A double-step algorithm using only integer arithmetic is presented to minimize the problem of oversampling. The algorithms for parametric curves have been implemented also on GPU. Through experiments we confirmed that the performance of this new algorithm is superior to previous algorithms.Keywords: computing; curves; pixels; rasterization;GPU
