Detailed Description

template<class T, class Scalar = typename T::Scalar>
class geomsort::ExtractPhi< T, Scalar >

functor to sort in phi (from -pi to pi) using precomputed_value_sort. Can be used for any object with a member position().

Note that sorting in phi is done within the phi range of (-pi, pi]. It may NOT be what you expect if the elements cluster around the pi discontinuity.

Use:

precomputed_value_sort(v.begin(), v.end(), ExtractPhi<Surface>());
