No matter if clippingRegion is defined in CW or CCW direction, it always gives me 2 lines as a result of intersection. But with the same input old boost gave me 1 (but very small) correct subsegment as a result. Could you please help with that? #include <boost/geometry.hpp> #include...

boost::geometry::intersection 函数的主要功能是计算两个几何对象之间的交集,并将结果存储到指定的输出迭代器中。交集可以是一个点、一条线、一个多边形等,具体取决于输入几何对象的类型和形状。 例如,如果两个输入几何对象是两个矩形,则交集可能是一个矩形、一条线段或一个点(如果两个矩形仅在一个点相交)。
最在项目中要用到计算几何的东西,计算三维空间中面片与六面体的相交判断,通过各种搜索发现boost库中的Geometry模块还不错,可以比较容易地实现。这里记录一下这个库的基本情况。 1、常见几何对象 #include <boost/geometry.hpp>#include<boost/geometry/geometries/point_xy.hpp>#include<boost/geometry/geometries/point....

我今天真的是被这个boost库搞到头炸，怎么在linux下安装boost库，及后续使用。一开始用sudo apt-get install libboost-dev倒是能解决代码中头文件引用不存在问题，但是编译不成功，总是会出现什么未定义引用错误，之后remove掉，重新下载源码编译还是会存在一些问题。
