11232,User defined spatial predicate within Boost Geometry,Frank Hippmann <frank.hippmann@…>,Barend Gehrels,"I need to determine whether the interiors of two geometries intersect. An InteriorsIntersect predicate is not specified by OGC or Boost Geometry but is defined by the DE-9IM matrix:

{{{

T * *
* * *
* * *
}}}

I've created my own predicate using the relate function in Boost Geometry.


{{{
namespace bgr = boost::geometry::detail::relate;
using InteriorsIntersectMask = bgr::static_mask<'T','*','*','*','*','*','*','*','*'>;

template<typename Geom1, typename Geom2>
inline bool interiorsIntersect(const Geom1& geom1, const Geom2& geom2)
{
    return bgr::relate<InteriorsIntersectMask>(geom1, geom2);
}
}}}

This works great. My only concern is that the relate function and static_mask type are not documented as part of the Boost Geometry API and are implementation details as far as I can tell. Is it safe to use relate in this way? Is there an alternative to achieving the same goal using Boost Geometry? Ideally I would like to see relate be an algorithm within boost/geometry/algorithms.",Feature Requests,closed,Boost 1.59.0,geometry,Boost 1.56.0,Problem,fixed,geometry relate,
