adjust point positions using Laplacian smoothing
<p>
<a class="el" href="a01566.html" title="adjust point positions using Laplacian smoothing">vtkSmoothPolyDataFilter</a> is a filter that adjusts point coordinates using Laplacian smoothing. The effect is to "relax" the mesh, making the cells better shaped and the vertices more evenly distributed. Note that this filter operates on the lines, polygons, and triangle strips composing an instance of <a class="el" href="a01260.html" title="concrete dataset represents vertices, lines, polygons, and triangle strips">vtkPolyData</a>. Vertex or poly-vertex cells are never modified.<p>
The algorithm proceeds as follows. For each vertex v, a topological and geometric analysis is performed to determine which vertices are connected to v, and which cells are connected to v. Then, a connectivity array is constructed for each vertex. (The connectivity array is a list of lists of vertices that directly attach to each vertex.) Next, an iteration phase begins over all vertices. For each vertex v, the coordinates of v are modified according to an average of the connected vertices. (A relaxation factor is available to control the amount of displacement of v). The process repeats for each vertex. This pass over the list of vertices is a single iteration. Many iterations (generally around 20 or so) are repeated until the desired result is obtained.<p>
There are some special instance variables used to control the execution of this filter. (These ivars basically control what vertices can be smoothed, and the creation of the connectivity array.) The BoundarySmoothing ivar enables/disables the smoothing operation on vertices that are on the "boundary" of the mesh. A boundary vertex is one that is surrounded by a semi-cycle of polygons (or used by a single line).<p>
Another important ivar is FeatureEdgeSmoothing. If this ivar is enabled, then interior vertices are classified as either "simple", "interior edge", or "fixed", and smoothed differently. (Interior vertices are manifold vertices surrounded by a cycle of polygons; or used by two line cells.) The classification is based on the number of feature edges attached to v. A feature edge occurs when the angle between the two surface normals of a polygon sharing an edge is greater than the FeatureAngle ivar. Then, vertices used by no feature edges are classified "simple", vertices used by exactly two feature edges are classified "interior edge", and all others are "fixed" vertices.<p>
Once the classification is known, the vertices are smoothed differently. Corner (i.e., fixed) vertices are not smoothed at all. Simple vertices are smoothed as before (i.e., average of connected vertex coordinates). Interior edge vertices are smoothed only along their two connected edges, and only if the angle between the edges is less than the EdgeAngle ivar.<p>
The total smoothing can be controlled by using two ivars. The NumberOfIterations is a cap on the maximum number of smoothing passes. The Convergence ivar is a limit on the maximum point motion. If the maximum motion during an iteration is less than Convergence, then the smoothing process terminates. (Convergence is expressed as a fraction of the diagonal of the bounding box.)<p>
There are two instance variables that control the generation of error data. If the ivar GenerateErrorScalars is on, then a scalar value indicating the distance of each vertex from its original position is computed. If the ivar GenerateErrorVectors is on, then a vector representing change in position is computed.<p>
Optionally you can further control the smoothing process by defining a second input: the Source. If defined, the input mesh is constrained to lie on the surface defined by the Source ivar.<p>
<dl class="warning" compact><dt><b>Warning:</b></dt><dd>The Laplacian operation 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. Enabling FeatureEdgeSmoothing helps reduce this effect, but cannot entirely eliminate it. You may also wish to try <a class="el" href="a01887.html" title="adjust point positions using a windowed sinc function interpolation kernel">vtkWindowedSincPolyDataFilter</a>. It does a better job of minimizing shrinkage.</dd></dl>
