Surface Quality and Smoothing
1.Computation of the uniform Laplacian operator and using it for smoothing (uniform Laplace smoothing)
2.Computation of the circum-radius to minimum edge length ratio to evaluate the triangle shapes of a mesh. Showing the effect of the smoothing algorithm in terms of their influence on the triangle shape.
3.Approximation of the Gaussian curvature.
