How to Calculate Centroid

Question

I am working with geospatial shapes and looking at the centroid algorithm here,

Answer 1

For 3d Points, I created a method in C # I hope I can help you:

public static double[] GetCentroid(List listOfPoints)
    {
        // centroid[0] = X
        // centroid[1] = Y
        // centroid[2] = Z
        double[] centroid = new double[3];

        // List iteration
        // Link reference:
        // https://en.wikipedia.org/wiki/Centroid
        foreach (double[] point in listOfPoints)
        {
            centroid[0] += point[0];
            centroid[1] += point[1];
            centroid[2] += point[2];
        }

        centroid[0] /= listOfPoints.Count;
        centroid[1] /= listOfPoints.Count;
        centroid[2] /= listOfPoints.Count;

        return centroid;
    }
