Function polygon_centroid 

pub fn polygon_centroid<T>(polygon: &Polygon<T>) -> Point<T, T>
where
    T: Clone + Copy + Add<Output = T> + Div<Output = T> + From<i32> + Zero + Num + AddAssign + Ord,

Computes the centroid (geometric center) of a polygon

The centroid is the arithmetic mean of all vertex positions:

$$\bar{x} = \frac{1}{n}\sum_{i=1}^{n} x_i,\qquad \bar{y} = \frac{1}{n}\sum_{i=1}^{n} y_i$$

Arguments

• polygon - The polygon

Returns

The centroid point of the polygon

Examples

use physdes::{Point, algorithms::polygon_centroid};
use physdes::Polygon;

let points = vec![
    Point::new(0, 0),
    Point::new(4, 0),
    Point::new(4, 3),
];
let polygon = Polygon::new(&points);

let centroid = polygon_centroid(&polygon);
// For a triangle, centroid is at the average of vertices
