I have my terrain modeled as a static trimesh, and I
need to know wich is the triangle id for a given
point. I need know this in the callback, for configure
the mu in function of the material of the triangle
(grass, stone..) 
I think that a Ray - Trimesh collision would do the
trick, but the contact Joint return the same thing
that I already know: the position of the contact. no
the triangle id. 
some clue? :(
