Creating convex 3D hulls?

Is there a command, script or plugin in existense that will take a selection (ideally vertices) and build a 3D convex hull from it? or even any functions that will assist in writing one..?
I realise this isn't exactly what you'd call a normal or very useful modelling tool so I'm not very hopeful on finding one, but I don't fancy having to write one in MEL as it involves some pretty heavy and complicated maths...
