Detailed Description

create 3D Delaunay triangulation of input points

vtkDelaunay3D 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 laying 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".) Note that a modification to alpha shapes enables output of combinations of tetrahedra, triangles, lines, and/or verts (see the boolean ivars AlphaTets, AlphaTris, AlphaLines, AlphaVerts).

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 vtkDelaunay2D.) 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., vtkDelaunay2D) 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.

virtual

Set / get a spatial locator for merging points.

By default, an instance of vtkPointLocator is used.

◆ CreateDefaultLocator()

void vtkDelaunay3D::CreateDefaultLocator ( )

◆ InitPointInsertion()

vtkUnstructuredGrid* vtkDelaunay3D::InitPointInsertion	(	double	center[3],
		double	length,
		vtkIdType	numPts,
		vtkPoints *&	points
	)

This is a helper method used with InsertPoint() to create tetrahedronalizations of points.

Its purpose is construct an initial Delaunay triangulation into which to inject other points. You must specify the center of a cubical bounding box and its length, as well as the number of points to insert. The method returns a pointer to an unstructured grid. Use this pointer to manipulate the mesh as necessary. You must delete (with Delete()) the mesh when done. Note: This initialization method places points forming bounding octahedron at the end of the Mesh's point list. That is, InsertPoint() assumes that you will be inserting points between (0,numPtsToInsert-1).

◆ InsertPoint()

void vtkDelaunay3D::InsertPoint	(	vtkUnstructuredGrid *	Mesh,
		vtkPoints *	points,
		vtkIdType	id,
		double	x[3],
		vtkIdList *	holeTetras
	)

This is a helper method used with InitPointInsertion() to create tetrahedronalizations of points.

Its purpose is to inject point at coordinates specified into tetrahedronalization. The point id is an index into the list of points in the mesh structure. (See vtkDelaunay3D::InitPointInsertion() for more information.) When you have completed inserting points, traverse the mesh structure to extract desired tetrahedra (or tetra faces and edges).The holeTetras id list lists all the tetrahedra that are deleted (invalid) in the mesh structure.

◆ EndPointInsertion()

void vtkDelaunay3D::EndPointInsertion ( )

Invoke this method after all points have been inserted.

The purpose of the method is to clean up internal data structures. Note that the (vtkUnstructuredGrid *)Mesh returned from InitPointInsertion() is NOT deleted, you still are responsible for cleaning that up.
