Hey,

i have an issue where i find self intersections in a polygon.but it doesn't seem to find the method_collinear type.

this is the piece of code:

namespace bg = boost::geometry;

using namespace std;

typedef bg::model::d2::point_xy<double> point_2d;

typedef bg::model::polygon<boost::geometry::model::d2::point_xy<double> > Polygon;

Polygon poly;

poly.outer().push_back(point_2d(0, 10));

poly.outer().push_back(point_2d(10, 0));

typedef bg::point_type<Polygon>::type point_type;

typedef bg::detail::overlay::traversal_turn_info

<point_type,typename bg::segment_ratio_type<point_type, bg::detail::no_rescale_policy>::type> turn_info;

bg::detail::self_get_turn_points::no_interrupt_policy noInteruptPolicy;

bg::detail::no_rescale_policy robust_policy;

std::vector<turn_info> turns;

bg::self_turns<bg::detail::overlay::assign_null_policy>(

poly, robust_policy, turns, noInteruptPolicy);
