摘要
Nano-X是一个基于客户端/服务器(C/S)体系结构的GUI,系统结构采用分层设计,包括设备驱动层、图形引擎层和应用接口层。Nano-X系统稳定且具有良好的可裁剪性和较高的实时性,但图形引擎中未采用任何反走样算法,图形存在较严重的图形阶梯现象。为解决这一问题,基于Wu反走样算法提出了一种新型快速反走样算法,通过降低运算量提高了算法快速性。仿真结果表明该算法提高了绘图效率,明显减少阶梯现象,同时算法具有较高的实时性。
Nano-x system works well at the aspects of stable,portability and real-time response. But as calling no graphical op- timization algorithm,graphics exist serious ladder-phenomenon in this system.Based on Wu anti-aliasing algorithm,this paper proposes a new fast anti-aliasing algorithm to accelerate the arithmetic process.As a result of the simulation we find that the algorithm improves the drawing effect,reduces the staircase phenomenon significantly.
