Detailed Description

a 3D cell defined by a set of polygonal faces

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 does not require the polyhedron to be convex. However, the polygonal faces must be planar. Non-planar polygonal faces will definitely cause problems, especially in severely warped situations.

This method returns a non-nullptr pointer when the cell is a primary type (i.e., IsPrimaryCell() is true). Note that 3D parametric coordinates are returned no matter what the topological dimension of the cell.

overridevirtual

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.

Reimplemented from vtkCell3D.

		vtkIdType	cellId,
		vtkCellData *	outCd,
		int	insideOut
	)

overridevirtual

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.

int vtkPolyhedron::EvaluatePosition	(	const double	x[3],
		double	closestPoint[3],
		int &	subId,
		double	pcoords[3],
		double &	dist2,
		double	weights[]
	)

overridevirtual

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.

Implements vtkCell.

void vtkPolyhedron::EvaluateLocation	(	int &	subId,
		const double	pcoords[3],
		double	x[3],
		double *	weights
	)

overridevirtual

The inverse of EvaluatePosition.

Note the weights should be the MVC weights.

Implements vtkCell.

int vtkPolyhedron::IntersectWithLine	(	const double	p1[3],
		const double	p2[3],
		double	tol,
		double &	t,
		double	x[3],
		double	pcoords[3],
		int &	subId
	)

overridevirtual

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 true if the line intersects a face.

Implements vtkCell.

int vtkPolyhedron::Triangulate	(	int	index,
		vtkIdList *	ptIds,
		vtkPoints *	pts
	)

overridevirtual

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.

Implements vtkCell.

void vtkPolyhedron::Derivatives	(	int	subId,
		const double	pcoords[3],
		const double *	values,
		int	dim,
		double *	derivs
	)

overridevirtual

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.

Implements vtkCell.

int vtkPolyhedron::CellBoundary	(	int	subId,
		const double	pcoords[3],
		vtkIdList *	pts
	)

overridevirtual

Find the boundary face closest to the point defined by the pcoords[3] and subId of the cell (subId can be ignored).

Implements vtkCell.

int vtkPolyhedron::GetParametricCenter ( double pcoords[3] )

inlineoverridevirtual

Return the center of the cell in parametric coordinates.

In this cell, the center of the bounding box is returned.

Compute the interpolation functions/derivatives (aka shape functions/derivatives).

Here we use the MVC calculation process to compute the interpolation functions.

int vtkPolyhedron::RequiresExplicitFaceRepresentation ( )

inlineoverridevirtual

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.

int vtkPolyhedron::IsInside	(	const double	x[3],
		double	tolerance
	)

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.

bool vtkPolyhedron::IsConvex ( )

Determine whether or not a polyhedron is convex.
