      <Documentation>Internal filter used by (filters, ProbeLine). The Plot
      Over Line filter samples the data set attributes of the current data set

      along that line will be displayed in an XY Plot. This filter uses
      interpolation to determine the values at the selected point, whether or

        <Documentation>When dealing with composite datasets, partial arrays are
        common i.e. data-arrays that are not available in all of the blocks. By
        default, this filter only passes those point and cell data-arrays that
        are available in all the blocks i.e. partial array are removed. When
        PassPartialArrays is turned on, this behavior is changed to take a
        union of all arrays present thus partial arrays are passed as well.
        However, for composite dataset input, this filter still produces a
        non-composite output. For all those locations in a block of where a
        particular data array is missing, this filter uses vtkMath::Nan() for
        double and float arrays, while 0 for all other types of arrays i.e int,
        char etc.</Documentation>

                     vtkAppendArcLength is used for filter such as

It expects a vtkPointSet as input and produces vtkPolyData as output.
The points are expected to be in a mostly planar distribution."
                     short_help="Create 2D Delaunay triangulation of input points.">
                     Delaunay2D is a filter that constructs a 2D Delaunay
                     triangulation from a list of input points. These points
                     may be represented by any dataset of type vtkPointSet and
                     subclasses. The output of the filter is a polygonal
                     dataset containing a triangle mesh. The 2D Delaunay
                     triangulation is defined as the triangulation that
                     satisfies the Delaunay criterion for n-dimensional
                     simplexes (in this case n=2 and the simplexes are
                     triangles). This criterion states that a circumsphere of
                     each simplex in a triangulation contains only the n+1
                     defining points of the simplex. In two dimensions, this
                     translates into an optimal triangulation. That is, the
                     maximum interior angle of any triangle is less than or
                     equal to that of any possible triangulation. Delaunay
                     triangulations are used to build topological structures
                     from unorganized (or unstructured) points. The input to
                     this filter is a list of points specified in 3D, even
                     though the triangulation is 2D. Thus the triangulation is
                     constructed in the x-y plane, and the z coordinate is
                     ignored (although carried through to the output). You can
                     use the option ProjectionPlaneMode in order to compute the
                     best-fitting plane to the set of points, project the
                     points and that plane and then perform the triangulation
                     using their projected positions and then use it as the
                     plane in which the triangulation is performed. The
                     Delaunay triangulation can be numerically sensitive in
                     some cases. To prevent problems, try to avoid injecting
                     points that will result in triangles with bad aspect
                     ratios (1000:1 or greater). In practice this means
                     inserting points that are "widely dispersed", and enables
                     smooth transition of triangle sizes throughout the mesh.
                     (You may even want to add extra points to create a better
                     point distribution.) If numerical problems are present,
                     you will see a warning message to this effect at the end
                     of the triangulation process. Warning: Points arranged on
                     a regular lattice (termed degenerate cases) can be
                     triangulated in more than one way (at least according to
                     the Delaunay criterion). The choice of triangulation (as
                     implemented by this algorithm) depends on the order of the
                     input points. The first three points will form a triangle;
                     other degenerate points will not break this triangle.
                     Points that are coincident (or nearly so) may be discarded
                     by the algorithm. This is because the Delaunay
                     triangulation requires unique input points. The output of
                     the Delaunay triangulation is supposedly a convex hull. In
                     certain cases this implementation may not generate the
                     convex hull.</Documentation>

                     short_help="Create a 3D Delaunay triangulation of input
                                points.">Delaunay3D is a filter that constructs
a 3D Delaunay triangulation from a list of input points. These points may be
represented by any dataset of type vtkPointSet and subclasses. The output of
the filter is an unstructured grid dataset. Usually the output is a tetrahedral
mesh, but if a non-zero alpha distance value is specified (called the "alpha"
value), then only tetrahedra, triangles, edges, and vertices lying within the
alpha radius are output. In other words, non-zero alpha values may result in
arbitrary combinations of tetrahedra, triangles, lines, and vertices. (The
notion of alpha value is derived from Edelsbrunner's work on "alpha shapes".)
The 3D Delaunay triangulation is defined as the triangulation that satisfies
the Delaunay criterion for n-dimensional simplexes (in this case n=3 and the
simplexes are tetrahedra). This criterion states that a circumsphere of each
simplex in a triangulation contains only the n+1 defining points of the
simplex. (See text for more information.) While in two dimensions this
translates into an "optimal" triangulation, this is not true in 3D, since a
measurement for optimality in 3D is not agreed on. Delaunay triangulations are
used to build topological structures from unorganized (or unstructured) points.
The input to this filter is a list of points specified in 3D. (If you wish to
create 2D triangulations see Delaunay2D.) The output is an unstructured grid.
The Delaunay triangulation can be numerically sensitive. To prevent problems,
try to avoid injecting points that will result in triangles with bad aspect
ratios (1000:1 or greater). In practice this means inserting points that are
"widely dispersed", and enables smooth transition of triangle sizes throughout
the mesh. (You may even want to add extra points to create a better point
distribution.) If numerical problems are present, you will see a warning
message to this effect at the end of the triangulation process. Warning: Points
arranged on a regular lattice (termed degenerate cases) can be triangulated in
more than one way (at least according to the Delaunay criterion). The choice of
triangulation (as implemented by this algorithm) depends on the order of the
input points. The first four points will form a tetrahedron; other degenerate
points (relative to this initial tetrahedron) will not break it. Points that
are coincident (or nearly so) may be discarded by the algorithm. This is
because the Delaunay triangulation requires unique input points. You can
control the definition of coincidence with the "Tolerance" instance variable.
The output of the Delaunay triangulation is supposedly a convex hull. In
certain cases this implementation may not generate the convex hull. This
behavior can be controlled by the Offset instance variable. Offset is a
multiplier used to control the size of the initial triangulation. The larger
the offset value, the more likely you will generate a convex hull; and the more
likely you are to see numerical problems. The implementation of this algorithm
varies from the 2D Delaunay algorithm (i.e., Delaunay2D) in an important way.
When points are injected into the triangulation, the search for the enclosing
tetrahedron is quite different. In the 3D case, the closest previously inserted
point point is found, and then the connected tetrahedra are searched to find
the containing one. (In 2D, a "walk" towards the enclosing triangle is
performed.) If the triangulation is Delaunay, then an enclosing tetrahedron
will be found. However, in degenerate cases an enclosing tetrahedron may not be
found and the point will be rejected.</Documentation>

        Decimate Polyline is a filter to reduce the number of lines in a
        polyline. The algorithm functions by evaluating an error metric for each
        vertex (i.e., the distance of the vertex to a line defined from the two
        vertices on either side of the vertex). Then, these vertices are placed
        into a priority queue, and those with smaller errors are deleted first.
        The decimation continues until the target reduction is reached. While the
        filter will not delete end points, it will decimate closed loops down to a
        single line, thereby changing topology.

        As this filter works on polylines, you may need to call Triangle Strips before calling
        this filter.
