Function nannou::geom::centroid

pub fn centroid<I, S>(vertices: I) -> Option<I::Item> where
    I: IntoIterator,
    I::Item: Vertex<Scalar = S> + EuclideanSpace<Scalar = S>,
    <I::Item as EuclideanSpace>::Diff: Div<S, Output = <I::Item as EuclideanSpace>::Diff>,
    S: BaseFloat, 

The centroid (average position) of all vertices in the given iterator.

Returns None if the given iterator contains no vertices.
