How do I find the center of a number of geographic points? 3,782 4 28 31 A centroid is the center of a region or shape, not the center of a number of distinct points – Moe Sep 24, 2008 at 17:07 1 A number of distinct points defines a shape, so we are dealing with a shape whether we call it that or not – newdayrising Sep 24, 2008 at 17:10
Whats the best way to calculate a 3D (or n-D) centroid? 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 As you can see you can define the centerpoint in different ways Below I am showing you examples of 2 2D point clouds with these suggestions in mind The dark blue dot is the average (mean
Calculate x y position from centerpoint in circle Based on degree, 270 in this example, I want to place the x-box on x y at the specified degree from the centerpoint I just cannot get it right, not even with the examples I have found Below is the current code I test as well as the result of 270 degree test, x-box is positioned wrongly as it is not 270 degree angle
algorithm - Better centerpoint than centroid - Stack Overflow It is guaranteed to cross the polygon Find the intersection with the sides and sort them by increasing abscissa Pick a point in the middle of two intersections This is an O (N + K Log K) process where K is the number of intersections (usually a very small even number) Pretty straightforward to write
WPF Center Ellipse at X, Y - Stack Overflow In other words, however you've determined that the Ellipse's center should land at (4,6), and that it should have Height Width = 10, the X and Y properties exposed by the ViewModel should have the values 4 - 10 and 6 - 10 (i e (-6,-4)), which would be the resulting values of Canvas Left and Canvas Top Update: After thinking about this a
graphics - Finding the centerpoint and boundaries of an arbitrary . . . If by 'centerpoint' you mean center of mass, and you are assuming uniform density, then this question has what you want If by 'boundaries' you mean bounding rectangle with sides parallel to the axes, you just need the minimum and maximum x and y values on the curve If either of those aren't what you mean, please say
