裁剪算法的一个新推广与应用研究

The Extension and Applicational Study of the Clipping Algoroithm on a Rectangle Window

裁剪是计算机图形处理的重要技法。平面图形的裁剪窗口过去多被定义为正立的矩形。本文探讨了它的一般形式——倾斜矩形窗的裁剪算法。

The clipping is the important skill of computer graphical processing.Theclipping window of two dimensional graphics always used to be defined as upright rectangle.In this paper,the clipping algorithm for an inclined rectanglar window is presented,the drawing programming based on this algorithm is introduced.In addition,an idea of clipping and convering combinatorial composition is presented, some valuable attempts are also given.
