Detailed Description

smooth mesh point attribute data using distance weighted Laplacian kernel

vtkAttributeSmoothingFilter is a filter that smooths point attribute data using a Laplacian smoothing approach. The effect is to "relax" or "smooth" the attributes, reducing high frequency information. Note that this filter operates on all dataset types.

A central concept of this filter is the point smoothing stencil. A smoothing stencil for a point p(i) is the list of points p(j) which connect to p(i) via an edge. To smooth the attributes of point p(i), p(i)'s attribute data a(i) are iteratively averaged using the distance weighted average of the attributes of a(j) (the weights w[j] sum to 1). This averaging process is repeated until the maximum number of iterations is reached.

The relaxation factor R is also important as the smoothing process proceeds in an iterative fashion. The a(i+1) attributes are determined from the a(i) attributes as follows:

a(i+1) = (1-R)*a(i) + R*sum(w(j)*a(j))

Convergence occurs faster for larger relaxation factors. Typically a small number of iterations is required for large relaxation factors, and in cases where only points adjacent to the boundary are being smoothed, a single iteration with R=1 may be adequate (i.e., just a distance weighted average is computed).

To control what regions in the dataset have their attributes smoothed, it is possible to specify which points (and their attributes) are allowed to be smoothed (and therefore also those that are constrained). Typically point data attributes may be constrained on the boundary, or only point attributes directly connected (i.e., adjacent) to the boundary may be allowed to change (this supports smooth transition of attributes from the boundary into the interior of the mesh). Note that the meaning of a boundary point (versus interior point) changes depending on the input dataset type. For vtkPolyData, boundary edges are used to identify boundary points; for all other dataset types, points used by a boundary face are considered boundary points. It is also possible to explicitly specify which points are smoothed, and those that are constrained, by specifying a smooth mask associated with each input point.

To control which point data attributes are to be smoothed, specify in ExcludedArrays which arrays should not be smoothed–these data arrays are simply passed through to the output of the filter.

Warning
Certain data attributes cannot be correctly interpolated using this filter. For example, surface normals are expected to be |n|=1; after attribute smoothing this constraint is likely to be violated. Other vectors and tensors may suffer from similar issues. In such a situation, specify ExcludedArrays which will not be smoothed (and simply passed through to the output of the filter).
Currently the distance weighting function is based on averaging, 1/r, or 1/(r**2) weights (user selectable), where r is the distance between the point to be smoothed and an edge connected neighbor (defined by the smoothing stencil). The weights are normalized so that sum(w(i))==1. When smoothing based on averaging, the weights are simply 1/n, where n is the number of connected points in the stencil.
The smoothing process reduces high frequency information in the data attributes. With excessive smoothing (large numbers of iterations, and/or a large relaxation factor) important details may be lost, and the attributes will move towards an "average" value.
While this filter will process any dataset type, if the input data is a 3D image volume, it's likely much faster to use an image-based algorithm to perform data smoothing.
To determine boundary points in vtkPolyData, edges used by only one cell are considered boundary (and hence the associated points defining the edge). To determine boundary points for all other dataset types, a vtkMarkBoundaryFilter is used to extract the boundary faces - this can be time consuming for large data.
