Detailed Description

cell represents a parabolic, 13-node isoparametric pyramid

vtkTriQuadraticPyramid is a concrete implementation of vtkNonLinearCell to represent a second order three-dimensional isoparametric 19-node pyramid. The interpolation is the standard finite element, tri-quadratic isoparametric shape function. The cell includes 5 corner nodes, 8 mid-edge nodes, 5 mid-face nodes, and 1 volumetric centroid node. The ordering of the nineteen points defining the cell is point ids (0-4, 5-12, 13-17, 18), where point ids 0-4 are the five corner vertices of the pyramid; followed by 8 mid-edge nodes (5-12); followed by 5 mid-face nodes (13-17), and the last node (19) is the volumetric centroid node. Note that these mid-edge nodes lie on the edges defined by (0, 1), (1, 2), (2, 3), (3, 0), (0, 4), (1, 4), (2, 4), (3, 4), respectively. The mid-face nodes lie on the faces defined by (first corner nodes id's, then mid-edge node id's): quadrilateral face: (0, 3, 2, 1, 8, 7, 6, 5), triangle face 1: (0, 1, 4, 5, 10, 9), triangle face 2: (1, 2, 4, 6, 11, 10), triangle face 3: (2, 3, 4, 7, 12, 11), triangle face 5: (3, 0, 4, 8, 9, 12). The last point lies in the center of the cell (0, 1, 2, 3, 4). The parametric location of vertex #4 is [0.5, 0.5, 1].

Note: It should be noted that the parametric coordinates that describe this cell are not distorted like in vtkPyramid and vtkQuadraticPyramid, which are a collapsed hexahedron. They are the actual uniform isoparametric coordinates, which are described in Browning's dissertation (see thanks section), but they are converted to [0, 1] space, and the nodes are rotated so that node-0 has x = 0, y = 0, while maintaining the CCW order.

◆ CellBoundary()

		vtkIdList *	pts
	)

overridevirtual

Given parametric coordinates of a point, return the closest cell boundary, and whether the point is inside or outside of the cell.

The cell boundary is defined by a list of points (pts) that specify a face (3D cell), edge (2D cell), or vertex (1D cell). If the return value of the method is != 0, then the point is inside the cell.

		vtkIdType	cellId,
		vtkCellData *	outCd
	)

overridevirtual

Generate contouring primitives.

The scalar list cellScalars are scalar values at each cell point. The point locator is essentially a points list that merges points as they are inserted (i.e., prevents duplicates). Contouring primitives can be vertices, lines, or polygons. It is possible to interpolate point data along the edge by providing input and output point data - if outPd is nullptr, then no interpolation is performed. Also, if the output cell data is non-nullptr, the cell data from the contoured cell is passed to the generated contouring primitives. (Note: the CopyAllocate() method must be invoked on both the output cell and point data. The cellId refers to the cell from which the cell data is copied.)

Implements vtkCell.

◆ EvaluatePosition()

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

overridevirtual

Given a point x[3] return inside(=1), outside(=0) cell, or (-1) computational problem encountered; evaluate parametric coordinates, sub-cell id (!=0 only if cell is composite), distance squared of point x[3] to cell (in particular, the sub-cell indicated), closest point on cell to x[3] (unless closestPoint is null, in which case, the closest point and dist2 are not found), and interpolation weights in cell.

(The number of weights is equal to the number of points defining the cell). Note: on rare occasions a -1 is returned from the method. This means that numerical error has occurred and all data returned from this method should be ignored. Also, inside/outside is determine parametrically. That is, a point is inside if it satisfies parametric limits. This can cause problems for cells of topological dimension 2 or less, since a point in 3D can project onto the cell within parametric limits but be "far" from the cell. Thus the value dist2 may be checked to determine true in/out.

Implements vtkCell.

	)

overridevirtual

Determine global coordinate (x[3]) from subId and parametric coordinates.

Also returns interpolation weights. (The number of weights is equal to the number of points in the cell.)

Implements vtkCell.

◆ IntersectWithLine()

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

overridevirtual

Line-edge intersection.

Intersection has to occur within [0,1] parametric coordinates and with specified tolerance.

Implements vtkCell.

◆ Triangulate()

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

overridevirtual

Generate simplices of proper dimension.

If cell is 3D, tetrahedron are generated; if 2D triangles; if 1D lines; if 0D points. The form of the output is a sequence of points, each n+1 points (where n is topological cell dimension) defining a simplex. The index is a parameter that controls which triangulation to use (if more than one is possible). If numerical degeneracy encountered, 0 is returned, otherwise 1 is returned. This method does not insert new points: all the points that define the simplices are the points that define the cell.

Implements vtkCell.

◆ Derivatives()

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

overridevirtual

Compute derivatives given cell subId and parametric coordinates.

The values array is a series of data value(s) at the cell points. There is a one-to-one correspondence between cell point and data value(s). Dim is the number of data values per cell point. Derivs are derivatives in the x-y-z coordinate directions for each data value. Thus, if computing derivatives for a scalar function in a hexahedron, dim=1, 8 values are supplied, and 3 deriv values are returned (i.e., derivatives in x-y-z directions). On the other hand, if computing derivatives of velocity (vx,vy,vz) dim=3, 24 values are supplied ((vx,vy,vz)1, (vx,vy,vz)2, ....()8), and 9 deriv values are returned ((d(vx)/dx),(d(vx)/dy),(d(vx)/dz), (d(vy)/dx),(d(vy)/dy), (d(vy)/dz), (d(vz)/dx),(d(vz)/dy),(d(vz)/dz)).

Implements vtkCell.

◆ GetParametricCoords()

double * vtkTriQuadraticPyramid::GetParametricCoords ( )

overridevirtual

Return a contiguous array of parametric coordinates of the points defining this cell.

In other words, (px,py,pz, px,py,pz, etc..) The coordinates are ordered consistent with the definition of the point ordering for the cell. 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.

Reimplemented from vtkCell.

◆ Clip()

void vtkTriQuadraticPyramid::Clip	(	double	value,
		vtkDataArray *	cellScalars,
		vtkIncrementalPointLocator *	locator,
		vtkCellArray *	tets,
		vtkPointData *	inPd,
		vtkPointData *	outPd,
		vtkCellData *	inCd,
		vtkIdType	cellId,
		vtkCellData *	outCd,
		int	insideOut
	)

overridevirtual

Clip this quadratic triangle using scalar value provided.

Like contouring, except that it cuts the triangle to produce linear triangles.

Implements vtkCell.

◆ GetParametricCenter()

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

inlineoverridevirtual

Return the center of the tri-quadratic pyramid in parametric coordinates.

Reimplemented from vtkCell.

Definition at line 219 of file vtkTriQuadraticPyramid.h.

◆ GetParametricDistance()

double vtkTriQuadraticPyramid::GetParametricDistance ( const double pcoords[3] )

overridevirtual

Return the distance of the parametric coordinate provided to the cell.

If inside the cell, a distance of zero is returned.

Reimplemented from vtkCell.

◆ InterpolationFunctions()

static void vtkTriQuadraticPyramid::InterpolationFunctions	(	const double	pcoords[3],
		double	weights[19]
	)

static

◆ InterpolationDerivs()

static void vtkTriQuadraticPyramid::InterpolationDerivs	(	const double	pcoords[3],
		double	derivs[57]
	)

static

◆ InterpolateFunctions()

void vtkTriQuadraticPyramid::InterpolateFunctions	(	const double	pcoords[3],
		double	weights[19]
	)

inlineoverride

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

Definition at line 171 of file vtkTriQuadraticPyramid.h.

◆ InterpolateDerivs()

void vtkTriQuadraticPyramid::InterpolateDerivs	(	const double	pcoords[3],
		double	derivs[57]
	)

inlineoverride

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

Definition at line 175 of file vtkTriQuadraticPyramid.h.

◆ JacobianInverse()

void vtkTriQuadraticPyramid::JacobianInverse	(	const double	pcoords[3],
		double **	inverse,
		double	derivs[57]
	)

Given parametric coordinates compute inverse Jacobian transformation matrix.

Returns 9 elements of 3x3 inverse Jacobian plus interpolation function derivatives.

◆ GetEdgeArray()

static const vtkIdType * vtkTriQuadraticPyramid::GetEdgeArray ( vtkIdType edgeId )

static

Return the ids of the vertices defining edge/face (edgeId/‘faceId’).

Ids are related to the cell, not to the dataset.

Note: The return type changed. It used to be int*, it is now const vtkIdType*. This is so ids are unified between vtkCell and vtkPoints.

◆ GetFaceArray()

static const vtkIdType * vtkTriQuadraticPyramid::GetFaceArray ( vtkIdType faceId )

static

Return the ids of the vertices defining edge/face (edgeId/‘faceId’).

Ids are related to the cell, not to the dataset.

Note: The return type changed. It used to be int*, it is now const vtkIdType*. This is so ids are unified between vtkCell and vtkPoints.
