Smooth (SmoothPolyDataFilter)
This filter smooths a polygonal surface by iteratively moving points toward their neighbors.
The Smooth filter operates on a polygonal data set by iteratively adjusting the position of the points using Laplacian smoothing. (Because this filter only adjusts point positions, the output data set is also polygonal.) This results in better-shaped cells and more evenly distributed points.



The Convergence slider limits the maximum motion of any point. It is expressed as a fraction of the length of the diagonal of the bounding box of the data set. If the maximum point motion during a smoothing iteration is less than the Convergence value, the smoothing operation terminates.

Convergence
(Convergence)
The value of this property limits the maximum motion of any point. It is expressed as a fraction of the length of the diagonal of the bounding box of the input dataset. If the maximum point motion during a smoothing iteration is less than the value of this property, the smoothing operation terminates. 0

The value must be greater than or equal to 0 and less than or equal to 1.

 
Input
(Input)
This property specifies the input to the Smooth filter.  

The selected object must be the result of the following: sources (includes readers), filters.

The selected dataset must be one of the following types (or a subclass of one of them): vtkPolyData.

 
Number of Iterations
(NumberOfIterations)
This property sets the maximum number of smoothing iterations to perform. More iterations produce better smoothing. 20

The value must be greater than or equal to 0.
