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文档(https://www.boost.org/doc/libs/1-73_0/libs/geometry/doc/html/geometry/reference/algorithms/intersection/intersection3.html)说明我可以使用点的矢量作为输出参数。 所以我写了这个: #include <iostream> #include <deque> #include <boost/geometry.hpp> #include <boost/geometry/geometries/register...

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)。

DE-9IM 是Dimensionally Extended 9-Intersection Model 的缩写,直接翻译为维度扩展的 9 相交模型好像比较别扭,但一时也找不到比较好的翻译。 DE-9IM 模型是用于描述两个 二维几何对象(点、线、面) 之间的空间关系的一种模型,它使用一个3 x 3的矩阵来描述几何关系类别(相交部分的维度)。

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。
