simple intersection

It's a simple intersection of a cylinder and a cube, he said of the piece, which he found at Katonah Architectural Hardware. It's such a classic, and I always return to it.

这仅仅是一个圆柱体与一个立方体的结合，谈及在Katonah建筑五金店找到的这件物品时，他说，这款门把手设计得太经典了，所以我总是一再回来购买。

We obtain a relation between the Nielsen number of coincidence points of two Dehn twists and the minimal geometric intersection number of the simple closed curves determining these two Dehn twist.

本文中，我们主要讨论曲面上一种特殊自同胚&Dehn twist的重合点，给出了重合点Nielsen数与闭曲线的最小几何相交数的联系。

Based on intersection detection algorithm of bounding volume hierarchy tree ( BVT), the method resolves the problem of relation determining for planar simple polygons by testing the position between monotone chains with sweep line technology.

算法在包围体层次树干涉检测算法基础上，利用扫描线技术判定单调链的位置关系，解决了一般多边形之间的位置关系判定问题。
