【摘要】 现代飞机座舱显示系统中数字化仪表通过各种图形向驾驶员提供信息,但常规画线函数、画弧函数绘制的图形都存在十分明显的锯齿现象,在显示屏分辨率一定的条件下,从软件算法上进行研究,根据飞机座舱显示的实际需求,兼顾绘制速度与线宽要求,提出了一套实用的直线、弧线反走样算法,并给出了基于Bresenham画线法和中点画圆法的具体反走样实现过程。更多还原

【Abstract】 In modern cockpit display system, digital meters provide information for pilot through all kinds of graphics. However, the graphics drawn by normal functions have obvious jaggies. In the condition of fixed display, it researchs on software measure, presents applied algorithms for line and arc with antialiasing on the base of actual requirement for drawing speed and line’s width, and presents material process with antialiasing based on Bresenham’s algorithm for line and the middle point algorithm for circle.更多还原
