Find a minimal bounding circle of a set of points in C#
The example Find the convex hull of a set of points in C# finds the convex hull of a set of points. A convex hull is the smallest convex polygon that encloses the points. This example extends that result to … Continue reading

Find a minimal bounding rectangle for a polygon in C#
This program assumes that its Points array contains the points in a convex polygon in counterclockwise order. If you have some other group of points, first find their convex hull and then orient the resulting polygon counterclockwise. See these related … Continue reading
Find the convex hull of a set of points in C#
This example shows how to find the convex hull for a set of points. The details are fairly complicated so I’m not going to show them all here, but the basic ideas are relatively straightforward. A convex hull is a … Continue reading
