Hi, I try boost::geometry::intersects algorithm(1 arg version) in Boost 1.47.0. Follow program result is "false". but, I hope result is "true". Is this Boost.Geometry bug? #include <iostream> #include #include namespace bg = boost::geometry; int main() { typedef bg::model::d2::point_xy<double> point; const bg::model::linestring<point> line = boost::assign::list_of<point> // (0, 0) // result become "true" when comment-in (0, 4) (4, 4) (2, 2) (2, 5) ; const bool result = bg::intersects(line); std::cout << std::boolalpha << result << std::endl; } Regards,
