Less functor, to sort points in ascending order.

This functor compares points and orders them on x, then on y, then on z coordinate. Geometry

the geometry

Dimension

the dimension to sort on, defaults to -1, indicating ALL dimensions. That's to say, first on x, on equal x-es then on y, etc. If a dimension is specified, only that dimension is considered

Strategy

underlying coordinate comparing functor, defaults to the default comparison strategies related to the point coordinate system. If specified, the specified strategy is used. This can e.g. be std::less<double>.
