algorithm - Better centerpoint than centroid - Stack Overflow I'm using the centroid of polygons to attach a marker in a map application This works definitely fine for convex polygons and quite good for many concave polygons However, some polygons (banana,
WPF Center Ellipse at X, Y - Stack Overflow I have an ItemsControl that draws thousands of Ellipses in a scatter plot on a Canvas My problem is, if I position an Ellipse at the coordinates (4, 6) with a Height and Width of 10 The top left
Find centerpoint of polygon in JavaScript - Stack Overflow Each set of coordinates has a latitude and longitude I have written the below code to find the centerpoint, but I am not sure if it does actually produce the centerpoint What if the polygon has 5 points instead of 4? Also, can this be done in a more efficient way, with less operations?
Whats the best way to calculate a 3D (or n-D) centroid? Now this will sort of do the opposite to the middle and actually help you ignore outliers in your point cloud and find a centerpoint based on the distribution of your points A more and robust way to find a "good" centerpoint might be to ignore the top and bottom 10% in each dimension and then calculate the average or median

Scaling vectors from a center point? - Stack Overflow If you know the center point cp and a point v in the polygon you would like to scale by scale, then: v2 = v - cp; get a vector to v relative to the centerpoint v2_scaled = v2 * scale; scale the cp-relative-vector v1_scaled = v2_scaled + cp; translate the scaled vector back This translate-scale-translate pattern can be performed on vectors of any dimension
