How to get convex hull of game objects?

[kAmehAmehA 0]

Hello, I've seen the getModel() method and getHullBounds() which is able to get my the bounding box of the objects.

However, is there a way to get the convex hull of an object (projected into game pixel coordinates)? I've found getModel().getVertexPoints() which I believe gets me the defining model points of the object. From this I can write my own algorithm to get the convex hull, but just wanted to make sure this doesn't exist yet.

I'm guessing there must be to define what's a clickable point within the model - I can see some functions relating to this, but struggling to find me the one specifically which defines the 2d hull of the object (not just rectangle). I will double check vertexPoints but that looks like it includes points inside the hull itself.

Cheers.
