Detailed Description

adjust point positions using constrained smoothing

vtkConstrainedSmoothingFilter is a filter that adjusts point coordinates using a modified Laplacian smoothing approach. The effect is to "relax" or "smooth" the mesh, making the cells better shaped and the points more evenly distributed. Note that this filter operates on any vtkPointSet and derived classes. Cell topology is never modified; note however if the constraints are too lax, cells may self-intersect or otherwise be deformed in unfavorable ways.

A central concept of this filter is the point smoothing stencil. A smoothing stencil for a point pi is the list of points pj which connect to pi via an edge. To smooth the point pi, pi is moved towards the average position of pj multiplied by the relaxation factor, and limited by the constraint distance. This process is repeated either until convergence occurs, or the maximum number of iterations is reached. Note that smoothing stencils may be specified; or if not provided, the stencils are computed from the input cells connected edges (using vtkExtractEdges with UseAllPoints enabled).

To constrain the motion of the points, either set the filter's constraint distance or constraint box, or provide an input point data array (of type vtkDoubleArray) named "SmoothingConstraints." The filter's constraint distance (or constraint box if selected) defines a local sphere (or box) centered on each point to restrict point motion and is applied to all points; whereas the smoothing data array may have different constraint values per point. If provided by the user, by default the smoothing data array takes precedence over the filter's constraint distance and constraint box.

Warning

The smoothing process reduces high frequency information in the geometry of the mesh. With excessive smoothing important details may be lost, and the surface may shrink towards the centroid. The constraints on point movement help significantly in preventing shrinkage from happening.

This filter is used internally by the filters vtkSurfaceNets2D and vtkSurfaceNets3D. vtkConstrainedSmoothingFilter is used by these filters to smooth the extracted surface net, with the constraint distance and constraint box set in relation to a volume voxel.

virtual void vtkConstrainedSmoothingFilter::SetConstraintStrategy ( int  )

If the strategy is set to CONSTRAINT_DISTANCE, then a constraint sphere defined by ConstraintDistance is used; while setting the strategy to CONSTRAINT_BOX an axis-aligned x-y-z box is used to constrain point motion (using constraint distance is slightly faster than using a constraint box). Note that is also possible to turn off constraints completely by simply specifying a very large constraint distance. The default constraint strategy is DEFAULT.
