Easiest the Qhull library in your code.

The Qhull Library has a central point with a few samples-to-start from when you want to use it in your code. Most interestingly, the developers invite-to-call the Qconvex program as a external application in case you want to C Alculate the convex hull of a point set. This is the easy-to-be-few-a-calls but would-be-lead-to-resource wasting in-case-you-want-do many calls. Of course, the developers tell you to use the C + + interface instead of the C interface. But on the same page, they tell is careful with the C + + bindings, as they is new and experimental. As confused as I am, here is the shortest-I know of the area and volume of a convex hull.
