c++ - boost::geometry::intersects 不适用于不同的几何类型？

Question

我正在尝试使用 boost::geometry::intersects 检查线段是否与多边形相交。以下代码运行良好:

#include <boost/geometry/algorithms/correct.hpp>
#include <boost/geometry/algorithms/intersects.hpp>
#include <boost/geometry/geometry.hpp>
#include <boost/geometry/io/wkt/read.hpp>
#include <iostream>

namespace bg = boost::geometry;

int main(int argc, char** argv) {
  typedef bg::model::point<double, 2, bg::cs::cartesian> Point;
  bg::model::ring<Point> poly1, poly2;
  bg::model::segment<Point> s1, s2;

  bg::read_wkt("POLYGON((0.0 0.0, 1.0 1.0, 0.0 2.0, 2.0 1.0))", poly1);
  bg::correct(poly1);

  bg::read_wkt("POLYGON((1.5 0.0, 1.5 2.0, 3.0 1.0))", poly2);
  bg::correct(poly2);

  bg::read_wkt("SEGMENT(0.0 0.0,0.0 2.0)", s1);
  bg::read_wkt("SEGMENT(-1.0 1.0,2.0 1.0)", s2);

  std::cout << "Polygons intersect " << bg::intersects(poly1, poly2) << std::endl;
  std::cout << "Segments intersect " << bg::intersects(s1, s2) << std::endl;
  //std::cout << "Polygon and segment intersect " << bg::intersects(poly1, s1) << std::endl;

  return 0;
}

但是，如果我用 bg::intersects(poly1, s1) 取消注释行，我会得到以下编译错误:

这是错误还是我忘记了什么？

Answer 1

这个问题有点老，但另一个答案不是很好。我的解决方案是将它们都转换成线串，然后找出它们是否相交(如果你考虑一下结果应该是相同的，但它不适用于相交)

#include <boost/geometry/algorithms/correct.hpp>
#include <boost/geometry/algorithms/intersects.hpp>
#include <boost/geometry/geometry.hpp>
#include <boost/geometry/io/wkt/read.hpp>
#include <iostream>

namespace bg = boost::geometry;

int main(int argc, char** argv) {
  typedef bg::model::point<double, 2, bg::cs::cartesian> Point;
  typedef bg::model::linestring<Point> linestring;
  bg::model::ring<Point> poly1, poly2;
  bg::model::segment<Point> s1, s2; 

  bg::read_wkt("POLYGON((0.0 0.0, 1.0 1.0, 0.0 2.0, 2.0 1.0))", poly1);
  bg::correct(poly1);

  bg::read_wkt("POLYGON((1.5 0.0, 1.5 2.0, 3.0 1.0))", poly2);
  bg::correct(poly2);

  bg::read_wkt("SEGMENT(0.0 0.0,0.0 2.0)", s1);
  bg::read_wkt("SEGMENT(-1.0 1.0,2.0 1.0)", s2);

  std::cout << "Polygons intersect " << bg::intersects(poly1, poly2) << std::endl;
  std::cout << "Segments intersect " << bg::intersects(s1, s2) << std::endl;
  std::vector<Point> v{s1.first,s1.second};
  std::cout << "Polygon and segment intersect " << bg::intersects(linestring(poly1.begin(),poly1.end()), linestring(v.begin(),v.end())) << std::endl;

  return 0;
