How can I create a tree from a set of points?

I triangulated a polygon and now i have to create the triangulation tree of the polygon. I calculated the barycenter of each triangle, so i thought that this set of points could be useful for me to create the tree. Is there already a function that can create a tree from a set of points?

Delaunay triangulation?

Yes I use DelaunayTri because i have the R2012b version.
