for the convex hull and area, you can use Polyhedron(). E.g. sage: p=Polyhedron(vertices = [[1, 1], [0, 0], [1, -1], [-1, 1], [-1, -1]]) sage: p.volume() 4 sage: p.vertices() (A vertex at (-1, -1), A vertex at (-1, 1), A vertex at (1, 1), A vertex at (1, -1)) -- You received this message because you are subscribed to the Google Groups "sage-support" group.
