Class LaplacianSmoother

java.lang.Object

maspack.geometry.LaplacianSmoother

public class LaplacianSmoother
extends java.lang.Object

Applies Laplacian or Taubin smoothing to a polygonal mesh. Taubin smoothing is a modification to Laplacian smoothing that can prevent shrinkage (see Taubin, ``Curve and surface smoothing without shrinkage'', Fifth International Conference on Computer Vision, 1995).

Method Detail

smooth

public static void smooth(PolygonalMesh mesh,
                          int numi,
                          double lam,
                          double mu)

Implements a specified number of iterations of Taubin smoothing. lam should be positive, and mu should be negative, with an absolute value greater than lam. Typical values are lam = 0.33, mu = -0.34. Setting lam = 1 and mu = 0 results in traditional Laplacian smoothing.

Parameters:

mesh - mesh to be smoothed

numi - number of iterations

lam - first Taubin parameter

mu - second Taubin parameter
