Get convex polygons from vertex

Question

Im writing a game in XNA and Im working right now in the pathfinding of the AI.

In my map there are some circular obstacles and I would like to use the mesh navigation technique (http://udn.epicgames.com/Three/NavigationMeshReference.html) so previously I need to convert those obstacles in a set of convex polygons.

Something like this: enter image description here

Ive been searching in google for long time but couldnt find how to do it. Any clue? Thanks!

Is a Delaunay triangulation what you are looking for?

Seems like that's a good starting place, then remove edges as long as the resulting shape remains convex. – Nuclearman May 31 '13 at 09:45
Yay! that was exactly what I was looking for! So I can get then the Voronoi diagram. Thanks Jason – Chemari May 31 '13 at 14:32
