例句與用法
- Second , after limitations of present algorithms are analyzed , two improved clipping algorithms of polygon against rectangle window and line against polygon window are presented
其次在分析現有算法不足的基礎上提出了矩形窗口多邊形裁剪和一般多邊形窗口線裁剪的改進算法。 - The new line against polygon window clipping algorithm which makes full use of two judgement conditions to confirm noneffective intersections between the lines and the polygon edges can only calculate the effective intersections and increases the efficiency of the clipping . third , a new 3 - d clipping algorithm of line against spherical surface window is introduced for the first time
一般多邊形窗口線裁剪的改進算法充分利用確定被裁線段與多邊形邊無交的兩個判斷條件，對完全不可見線段以及與被裁線段無有效交點的多邊形邊進行了排除，只有當線段與多邊形邊有有效交點時才求交，避免了不必要的求交，提高了算法效率。
