Sampling on the surface #75

First, thank you for your great work. The results are really awesome! I have a small question when I browsed the part where you try to sample on the surface. eps = np.random.dirichlet((0.5, 0.5, 0.5), size=faces.shape[0]) Correct me if I'm wrong, I think a uniform sampling should be with alpha (1.0, 1.0, 1.0) as param right? Why use (0.5, 0.5, 0.5) instead?
