Detailed Description

create a 3D Voronoi tessellation of input points

vtkVoronoiFlower3D is a filter that constructs a 3D Voronoi tessellation of a list of input points. The points are presumed to lie within 3D-space and non-coincident. These points may be represented by any dataset of type vtkPointSet and subclasses. Multiple different outputs of the filter are produced depending on the output types selected (as described shortly); for example, an unstructured grid consisting of polyhedral cells, an unstructured grid consisting of a Delaunay tetrahedralization, an adjacency graph, a polygonal complex, exterior boundary of the tessellation, and/or a generalized surface net can be produced.

The 3D Voronoi tessellation is a tessellation of space, where each Voronoi n-dimensional tile (in 3D, a polyhedron, also referred to as a point hull, or more simply, hull) represents the region nearest to one of the input points. Voronoi tessellations are important in computational geometry (and many other fields), and form the dual of Delaunay triangulations. Note that in this implementation, points may be labeled (or segmented) with an optional region id, this is useful for specifiying inside / outside, so as to control the tessellation, as well as creating contours between regions (a surface net). (Please note that region ids < 0 mean that the associated point is considered "outside" or "exterior"; this can be used to carve away areas that should not be tessellated.)

This filter is a reference implementation written with simplicity in mind. Additional methods are available for debugging / instructional purposes. This includes producing a single hull under various stages of creation, as well as the Voronoi flower and circumflower, the error metric controlling Voronoi's point insertion / half-space clipping process.

Publications are in preparation to describe the algorithm. A brief summary is as follows. In parallel, each (generating) input point is associated with an initial Voronoi hull, which is simply the bounding box of the input point set. A locator is then used to identify nearby points: each neighbor in turn generates a clipping plane positioned halfway between the generating point and the neighboring point, and orthogonal to the line connecting them. Clips are readily performed by evaluationg the vertices of the convex Voronoi hull as being on either side (inside,outside) of the clip plane. If an intersection with the Voronoi 3D hull is found, the portion of the hull "outside" the clip line is discarded, resulting in a new convex, Voronoi hull. As each clip occurs, the Voronoi "Flower" error metric (the union of error spheres) is compared to the extent of the region containing the neighboring clip points. The clip region (along with the points contained in it) is grown by careful expansion, When the Voronoi circumflower is contained within the clip region, the algorithm terminates and the Voronoi hull is output. Once complete, it is possible to construct the Delaunay triangulation from the Voronoi tessellation, or extract a generalized surface net between regions. Note that topological and geometric information is used to generate a valid triangulation (e.g., merging points and validating topology).

The filter produces different outputs depending on how the filter is configured. The filter accepts any vtkPointSet (and derived classes) as input. vtkUnstructuredGrid output is produced when the requested output type is a Voronoi tessellation or Delaunay tetrahedralization. vtkPolyData is produced when all other types of output are requested (e.g., adjacency graph, boundary faces, surface net contours, etc. (Use the methods GetUnstructuredGridOutput() or GetPolyDataOutput() to retrieve the appropriate output.)

A useful, optional feature of this filter is its ability to control the tessellation process and/or generation of a surface net via an input region ids array. The optional region ids array is a single component, signed integer array (vtkIntArray) that labels each input point as part of a segmented region, with value <0 meaning outside. As a result, this filter can be used to tessellate different regions using convex polygons (i.e., Voronoi hulls), or create holes in Voronoi tessellations, using this supplemental input single-component, scalar data array (the region ids array). The size of the region ids array must match the number of input points (the region ids must be provided as input point data).

This input region ids array can also be used to create a generalized 3D surface net. (See vtkSurfaceNets3D and vtkSurfaceNets2D for surface nets algorithms specialized to image data; and vtkGeneralizedSurfaceNets3D for a general surface nets algorithm based on this Voronoi approach.) A surface net is a type of contour that partitions segmented portions of the input volumetric space into separate regions. (The segmentation process requires the labeling of the input points as a member of a specified region. The segmentation is represented by integral, input scalar point data "region ids".) The resulting surface contour is not necessarily manifold, and typically contains inner structures or "bubbles" demarcating separate portions of the input. (Note that the output surface net can be smoothed by the filters like the vtkConstrainedSmoothingFilter, or vtkWindowedSincPolyDataFilter.)

This class can also construct an adjacency graph, composed of edges (the spokes) that connect each Voronoi hull generating point (the wheels) with their face neigbors. The adjacency graph is a powerful data representation that captures proximal neighborhood information. It has many practical applications such as shortest path computation.

There are two common use cases when using this filter. The first case simply produces output for the purposes of visualization. In this case the resulting output meshes are not watertight and cannot be smoothed (so-called meshless complex of polygons or Voronoi polyhedra). The second use case produces connected, watertight surface meshes or polyhedra which can be processed via downstream filters. Note that this second case requires a fair amount of work to merge nearly coincident points to produce the watertight surfaces. (Note: a built-in topologically-based point merging process is used. Alternatively, users can disable the built in point merging process, and use subsequent filters like vtkStaticCleanPolyData to merge coincident points, remove degenerate face primitives, etc, and otherwise process the surfaces with smoothing etc. vtkStaticCleanPolyData uses a proximal geometric point merging process requiring a tolerance, this can cause problems in some cases.)

An implementation note: this filter is implemented using a parallel algorithm, but produces invariant output in terms of the construction of the geometric primitives (Voronoi cells, adjacency graphs, etc.) Each input generating point of ptId, produces convex Voronoi hulls of hullId, where ptId == hullId. This means for debugging purposes, picking output primitives with POINT_IDS enabled provides a means to select the original generating hull.

Note
Note that the class vtkGeneralizedSurfaceNets3D can also generate a surface net. However the difference is that in vtkGeneralizedSurfaceNets3D the label values are explicitly specified, only specified labels may generate surfaces. The class vtkVoronoiFlower3D will generate surfaces for each non-negative region id enumerated in the region ids array. In addition, vtkGeneralizedSurfaceNets3D has the ability to smooth the resulting surfaces, as well as perform auxiliary functions such as triangulating the output polygons.
There are several utility classes that can be used with vtkVoronoiFlower3D to massage data and improve performance.
vtkFillPointCloud can add points to a set of input points P. These points
are labeled "outside" of P, placed in areas where no existing points exist
in P. Adding these outside points can markedly improve performance and
improve the quality of the output mesh.
vtkLabeledImagePointSampler can be used to transform a segmented image
into a point cloud suitable for processing by vtkVoronoiFlower3D (and related
filters). By using this filter along with image crop filters it is
possible to "snip" out areas of interest, producing a sample of points
and processing them as an input point cloud.
vtkJogglePoints can be used to improve the performance and quality of the
output mesh. Voronoi and Delaunay methods are known for their sensitivity
to numerical degeneracies (e.g., more than n+1 points cospherical to a
n-dimensional simplex in a n-dimensional Delaunay trianglulation). The
filter randomly perturbs (i.e., joggles or jitters) a point set thereby
removing degeneracies.
Warning
Coincident input points are discarded. The Voronoi tessellation requires unique input points.
This is a meshless Voronoi approach that implements an embarrassingly parallel algorithm. At the core of the algorithm a locator is used to determine points close to a specified position. Currently, a vtkStaticPointLocator is used because it is both threaded (when constructed) and supports thread-safe queries. While other locators could be used in principal, they must support thread-safe operations. This is done by defining and implementing an iterator that enables traversal of neighborhood points surrounding each generating point.
This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly. For example, in recent benchmarks using a 48-thread desktop, one million points can be processed in well under one second elapsed time.

◆ GenerateCellScalarsStrategy

Specify how to generate cell scalars for the outputs.

Note that some output styles (e.g., BOUNDARY) may produce multiple output primitives for each Voronoi hull processed, each of these primitives will take on the same cell scalar value as the generating hull (unless RANDOM is specified). So what's effectively happening here is that a scalar value is assigned to each generating Voronoi hull, and any surface primitives (surface primitives are convex polygons) generated by the hull assume that scalar value. On the other hand, the PRIM_ID option assigns different cell scalar values based on the primitive number (i.e., so primitive faces etc. will have different cell scalar values even if they originate from the same hull). Finally, random produces up to 64 random integer values for each output primitive.

◆ FindHull()

vtkIdType vtkVoronoiFlower3D::FindHull ( double x[3])

The following method–FindHull()–can be used to locate/query the Voronoi hull containing a point x (i.e., given that a Voronoi hull Vi is a region of closest proximity to the generating point x).

FindHull() returns the tile id/point id of a query location x. Note that if the query point x is outside of the bounds of the input point set, an id value <0 is returned.

virtual void vtkVoronoiFlower3D::SetPointOfInterest ( vtkIdType )
virtual

These methods are for debugging or instructional purposes.

When the point of interest is specified (i.e., set to a non-negative number) then the algorithm will process this single point (whose id is the PointOfInterest). When PointsOfInterest is specified through a supplied vtkIdTypeArray (this is in addition to the PointOfInterest), then only those hulls in the set (PointOfInterest + PointsOfInterestArray) will be produced. The maximum number of clips (the MaximumNumberOfHullClips) can be specified. If MaximumNumberOfHullClips=0, then the initial tile (single point within the bounding box) is produced; if =1 then the split with the closest point is produced; and so on. By default the PointOfInterest is set to (-1), and the number of clips is unlimited (i.e., MaximumNumberOfHullClips=VTK_ID_MAX and therefore automatically limited by the algorithm).
