1) Ellipse Clipping
椭圆窗口裁剪
2) clipping of circular window
圆形窗口裁剪
1.
Method for clipping of circular window based on AutoCAD system;
基于AutoCAD下圆形窗口裁剪法
3) window clipping
窗口裁剪
1.
Based on the characteristics of AutoCAD drawing and functions of operating the drawing in AutoCAD, it is proposed that the closed window boundary should be transformed into the region before the calculation of window clipping and the generating method is given.
根据 Auto CAD图形的特点及 Auto CAD中已有的功能提出 ,将封闭的窗口定义成“面域 (region)”参与裁剪运算 ,并给出了面域的自动生成方法 ;提出将被裁图形实体分成开环实体和闭环实体分别进行处理 :对开环实体 ,利用 Object ARX提供的实体求交函数实现了求交和排序同步完成 ;对闭环实体 ,组合使用“面域”的布尔操作实现窗口裁剪。
2.
Then, we propose a resolution to the key problems such as window clipping and window operations to implement the translucent system.
本文提出了一种适合计算半透明窗口混合颜色的图像混合公式,详细介绍了实现窗口系统半透明机制需要解决的窗口裁剪、窗口操作等关键问题的解决方案。
4) clipping window
裁剪窗口
1.
The intersection points of the circle and each side of the clipping window are calculated and sorted correctly.
讨论了圆关于任意多边形窗口的一个裁剪算法,按逆时针方向依次求出多边形裁剪窗口的每条边与圆的交点并且保证交点正确排序,对于交点序列中的任意两相邻的交点,采用"中点检测法"来判定以它们为端点的圆弧与裁剪窗口的位置关系,最后给出完整的裁剪算法。
5) ellipse window
椭圆窗口
1.
Because clipping is one of basis algorithms in computer graphics,it is necessary to find out a high-efficiency clipping algorithm based on ellipse window.
现有的椭圆窗口裁剪算法需通过求交运算确定裁剪对象,算法复杂,而且只适用于简单图形的裁剪。
