How do I compare Boost Geometries?

问题

I have 2 of these boost::geometry::model::ring and I am trying to tell if they are the same. Is there a built in boost geometry compare function/method that can figure this out for me?

回答1:

boost::geometry::equals(a,b) reports if two geometries are spatially equal
