Detailed Description

cell represents a parabolic, 13-node isoparametric pyramid

vtkQuadraticPyramid is a concrete implementation of vtkNonLinearCell to represent a three-dimensional, 13-node isoparametric parabolic pyramid. The interpolation is the standard finite element, quadratic isoparametric shape function. The cell includes a mid-edge node. The ordering of the thirteen points defining the cell is point ids (0-4,5-12) where point ids 0-4 are the five corner vertices of the pyramid; followed by eight midedge nodes (5-12). Note that these midedge 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 parametric location of vertex #4 is [0, 0, 1].

◆ GetFace()

Implements vtkCell.

◆ CellBoundary()

int vtkQuadraticPyramid::CellBoundary ( int  subId,
const double  pcoords[3],
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.

Implements vtkCell.

◆ Contour()

void vtkQuadraticPyramid::Contour ( double  value,
vtkDataArray cellScalars,
vtkIncrementalPointLocator locator,
vtkCellArray verts,
vtkCellArray lines,
vtkCellArray polys,
vtkPointData inPd,
vtkPointData outPd,
vtkCellData inCd,
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 vtkQuadraticPyramid::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.

◆ EvaluateLocation()

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

◆ TriangulateLocalIds()

int vtkQuadraticPyramid::TriangulateLocalIds ( int  index,
vtkIdList ptIds 
)
overridevirtual

Generate simplices of proper dimension.

If cell is 3D, tetrahedra 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. ptIds are the local indices with respect to the cell

Implements vtkCell.

◆ Derivatives()

void vtkQuadraticPyramid::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* vtkQuadraticPyramid::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.

)
inlineoverride

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

Definition at line 127 of file vtkQuadraticPyramid.h.

◆ GetEdgeArray()

static const vtkIdType* vtkQuadraticPyramid::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* vtkQuadraticPyramid::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.

◆ JacobianInverse()

void vtkQuadraticPyramid::JacobianInverse ( const double  pcoords[3],
double **  inverse,
double  derivs[39] 
)

Given parametric coordinates compute inverse Jacobian transformation matrix.

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

◆ Subdivide()

void vtkQuadraticPyramid::Subdivide ( vtkPointData inPd,
vtkCellData inCd,
vtkIdType  cellId,
vtkDataArray cellScalars 
)
protected

This method adds in a point at the center of the quadrilateral face and then interpolates values to that point.

In order to do this it also resizes certain member variable arrays. For safety should call ResizeArrays() after the results of Subdivide() are not needed anymore.

◆ ResizeArrays()

void vtkQuadraticPyramid::ResizeArrays ( vtkIdType  newSize)
protected

Resize the superclasses' member arrays to newSize where newSize should either be 13 or 14.

Call with 13 to reset the reallocation done in the Subdivide() method or call with 14 to add one extra tuple for the generated point in Subdivice. For efficiency it only resizes the superclasses' arrays.
