基于灰度递推的反走样圆生成算法
Algorithm for generating anti-aliasing circle based on gray recurrence
摘要
Abstract
With the development of special graphic display technology, high requirements have been put forward to the effect of it. In order to improve the anti-aliasing efficiency, recursive relationship has been set up between the pixel gray and coordinates of the circle. In the algorithm, pixel gray nearest to the circle in each loop is used as decision parameters. Quadratic term is eliminated to simplify calculation, and the error is amended it takes. Since gray results can be obtained without calculation or conversion, the algorithm is more effective than others. Test shows that the result of this anti-aliasing algorithm has improved the execution efficiency.关键词
