Method Detail

smooth

public static final BufferMesh smooth(Mesh mesh)

Smooth the specified mesh using the Taubin smoothing algorithm, with default parameters.

Parameters:

mesh - the mesh to smooth.

Returns:

a new smoothed mesh.

smooth

public static final BufferMesh smooth(Mesh mesh,
                                      int iters,
                                      double passBand)

Smooth the specified mesh using the Taubin smoothing algorithm, using cotangent weights.

Parameters:

mesh - the mesh to smooth.

iters - the number of iterations to apply. Typical values: 10.

passBand - the spatial frequency to use for smoothing. For instance 0.1.

Returns:

a new smoothed mesh.

                                      TaubinSmoothing.TaubinWeightType weightType)

Smooth the specified mesh using the Taubin smoothing algorithm.

Parameters:

mesh - the mesh to smooth.

iters - the number of iterations to apply. Typical values: 10.

lambda - the value of the lambda step in Taubin smoothing. Positive, typical values are around 0.5;

mu - the value of the mu step in Taubin smoothing. Negative, typical values are around -0.5.

weightType - the type of weights to use when summing contribution from neighbor edges.

Returns:

a new smoothed mesh.
