Before revision:  We show that these discrete conformal maps converge to the Riemann mapping uniformly and in H^1  . Additionally,  the discrete conformal maps  are known to be bijective , and we show that the Riemann mapping between two bounded Lipschitz domains can be approximated arbitrarily well by composing the Riemann mapping between each Lipschitz domain and the triangle.
