Arguably it should return a single finite distance for vectors aimed directly at the given point, but due to floating-point inaccuracy this is problematic. Note that the envelope for a single point is not the empty envelope (see Diagrams.Core.Envelope). |

centroid :: (Additive v, Fractional n) => [Point v n] -> Point v n Source #
The centroid of a set of n points is their sum divided by n.

Create a "point diagram", which has no content, no trace, an empty query, and a point envelope.
