Public Member Functions
	vtkPolyhedron (IntPtr rawCppThis, bool callDisposalMethod, bool strong)
	Automatically generated constructor - called from generated code. DO NOT call directly.
	vtkPolyhedron ()
	Standard new methods.
override int	CellBoundary (int subId, IntPtr pcoords, vtkIdList pts)
	Find the boundary face closest to the point defined by the pcoords[3] and subId of the cell (subId can be ignored).
override void	Clip (double value, vtkDataArray scalars, vtkIncrementalPointLocator locator, vtkCellArray connectivity, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, int cellId, vtkCellData outCd, int insideOut)
	Satisfy the vtkCell API. This method clips the input polyhedron and outputs a new polyhedron. The face information of the output polyhedron is encoded in the output vtkCellArray using a special format: CellLength [nCellFaces, nFace0Pts, i, j, k, nFace1Pts, i, j, k, ...]. Use the static method vtkUnstructuredGrid::DecomposePolyhedronCellArray to convert it into a standard format. Note: the algorithm assumes water-tight polyhedron cells.
override void	Contour (double value, vtkDataArray scalars, vtkIncrementalPointLocator locator, vtkCellArray verts, vtkCellArray lines, vtkCellArray polys, vtkPointData inPd, vtkPointData outPd, vtkCellData inCd, int cellId, vtkCellData outCd)
	Satisfy the vtkCell API. This method contours the input polyhedron and outputs a polygon. When the result polygon is not planar, it will be triangulated. The current implementation assumes water-tight polyhedron cells.
override void	Derivatives (int subId, IntPtr pcoords, IntPtr values, int dim, IntPtr derivs)
	Computes derivatives at the point specified by the parameter coordinate. Current implementation uses all vertices and subId is not used. To accelerate the speed, the future implementation can triangulate and extract the local tetrahedron from subId and pcoords, then evaluate derivatives on the local tetrahedron.
override void	EvaluateLocation (ref int subId, IntPtr pcoords, IntPtr x, IntPtr weights)
	The inverse of EvaluatePosition. Note the weights should be the MVC weights.
override int	EvaluatePosition (IntPtr x, IntPtr closestPoint, ref int subId, IntPtr pcoords, ref double dist2, IntPtr weights)
	Satisfy the vtkCell API. The subId is ignored and zero is always returned. The parametric coordinates pcoords are normalized values in the bounding box of the polyhedron. The weights are determined by evaluating the MVC coordinates. The dist is always zero if the point x[3] is inside the polyhedron; otherwise it's the distance to the surface.
override int	GetCellType ()
	See the vtkCell API for descriptions of these methods.
override vtkCell	GetEdge (int arg0)
	A polyhedron is represented internally by a set of polygonal faces. These faces can be processed to explicitly determine edges.
override vtkCell	GetFace (int faceId)
	A polyhedron is represented internally by a set of polygonal faces. These faces can be processed to explicitly determine edges.
override IntPtr	GetFaces ()
	Methods supporting the definition of faces. Note that the GetFaces() returns a list of faces in vtkCellArray form; use the method GetNumberOfFaces() to determine the number of faces in the list. The SetFaces() method is also in vtkCellArray form, except that it begins with a leading count indicating the total number of faces in the list.
override int	GetNumberOfEdges ()
	A polyhedron is represented internally by a set of polygonal faces. These faces can be processed to explicitly determine edges.
override int	GetNumberOfFaces ()
	A polyhedron is represented internally by a set of polygonal faces. These faces can be processed to explicitly determine edges.
override int	GetParametricCenter (IntPtr pcoords)

override IntPtr	GetParametricCoords ()
	See vtkCell3D API for description of these methods.
vtkPolyData	GetPolyData ()
	Construct polydata if no one exist, then return this->PolyData.
override void	Initialize ()
	This cell requires that it be initialized prior to access.
override void	InterpolateDerivs (IntPtr x, IntPtr derivs)
	Compute the interpolation functions/derivatives (aka shape functions/derivatives). Here we use the MVC calculation process to compute the interpolation functions.
override void	InterpolateFunctions (IntPtr x, IntPtr sf)
	Compute the interpolation functions/derivatives (aka shape functions/derivatives). Here we use the MVC calculation process to compute the interpolation functions.
override int	IntersectWithLine (IntPtr p1, IntPtr p2, double tol, ref double t, IntPtr x, IntPtr pcoords, ref int subId)
	Intersect the line (p1,p2) with a given tolerance tol to determine a point of intersection x[3] with parametric coordinate t along the line. The parametric coordinates are returned as well (subId can be ignored). Returns the number of intersection points.
override int	IsA (string type)
	Standard new methods.
int	IsInside (IntPtr x, double tolerance)
	Descriprion: A method particular to vtkPolyhedron. It determines whether a point x[3] is inside the polyhedron or not (returns 1 is the point is inside, 0 otherwise). The tolerance is expressed in normalized space; i.e., a fraction of the size of the bounding box.
override int	IsPrimaryCell ()
	A polyhedron is a full-fledged primary cell.
new vtkPolyhedron	NewInstance ()
	Standard new methods.
override int	RequiresExplicitFaceRepresentation ()
	Methods supporting the definition of faces. Note that the GetFaces() returns a list of faces in vtkCellArray form; use the method GetNumberOfFaces() to determine the number of faces in the list. The SetFaces() method is also in vtkCellArray form, except that it begins with a leading count indicating the total number of faces in the list.
override int	RequiresInitialization ()
	This cell requires that it be initialized prior to access.
override void	SetFaces (IntPtr faces)
	Methods supporting the definition of faces. Note that the GetFaces() returns a list of faces in vtkCellArray form; use the method GetNumberOfFaces() to determine the number of faces in the list. The SetFaces() method is also in vtkCellArray form, except that it begins with a leading count indicating the total number of faces in the list.
override int	Triangulate (int index, vtkIdList ptIds, vtkPoints pts)
	Use vtkOrderedTriangulator to tetrahedralize the polyhedron mesh. This method works well for a convex polyhedron but may return wrong result in a concave case. Once triangulation has been performed, the results are saved in ptIds and pts. The ptIds is a vtkIdList with 4xn number of ids (n is the number of result tetrahedrons). The first 4 represent the point ids of the first tetrahedron, the second 4 represents the point ids of the second tetrahedron and so on. The point ids represent global dataset ids. The points of result tetrahedons are stored in pts. Note that there are 4xm output points (m is the number of points in the original polyhedron). A point may be stored multiple times when it is shared by more than one tetrahedrons. The points stored in pts are ordered the same as they are listed in ptIds.

Detailed Description

vtkPolyhedron - a 3D cell defined by a set of polygonal faces

Description vtkPolyhedron is a concrete implementation that represents a 3D cell defined by a set of polygonal faces. The polyhedron should be watertight, non-self-intersecting and manifold (each edge is used twice).

Interpolation functions and weights are defined / computed using the method of Mean Value Coordinates (MVC). See the VTK class vtkMeanValueCoordinatesInterpolator for more information.

The class assumes that the polyhedron is non-convex. However, the polygonal faces should be planar. Non-planar polygonal faces will definitely cause problems, especially in severely warped situations.
