create an area from a set of points
How to create an area from a set of points ? I searched everywhere but could not find a better solution for it. Let抯 say that I have a matrix that contains the points for a shape. I抣l need a way to connect the points near each other continuously to form the outline for the shape.
Thanks fro any feedback.

Do you mean the Convex Hull [1] of a set of points?
If so, you could find it by implementing a Graham Scan [2] algorithm and then calculating the area of the polygon [3].
