Detailed Description

a cell that represents a linear 3D hexahedron

vtkHexahedron is a concrete implementation of vtkCell to represent a linear, 3D rectangular hexahedron (e.g., "brick" topology). vtkHexahedron uses the standard isoparametric shape functions for a linear hexahedron. The hexahedron is defined by the eight points (0-7) where (0,1,2,3) is the base of the hexahedron which, using the right hand rule, forms a quadrilaterial whose normal points in the direction of the opposite face (4,5,6,7).

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkCell3D.

◆ GetEdgePoints()

void vtkHexahedron::GetEdgePoints ( int  edgeId,
int *&  pts 
)
overridevirtual

See vtkCell3D API for description of these methods.

Implements vtkCell3D.

◆ GetFacePoints()

void vtkHexahedron::GetFacePoints ( int  faceId,
int *&  pts 
)
overridevirtual

Get the list of vertices that define a face.

The list is terminated with a negative number. Note that the vertices are 0-offset; that is, they refer to the ids of the cell, not the point ids of the mesh that the cell belongs to. The faceId must range between 0<=faceId<this->GetNumberOfFaces().

Implements vtkCell3D.

◆ GetCellType()

int vtkHexahedron::GetCellType ( )
inlineoverridevirtual

See the vtkCell API for descriptions of these methods.

Implements vtkCell.

Definition at line 60 of file vtkHexahedron.h.

◆ GetNumberOfEdges()

int vtkHexahedron::GetNumberOfEdges ( )
inlineoverridevirtual

Return the number of edges in the cell.

Implements vtkCell.

Definition at line 61 of file vtkHexahedron.h.

◆ GetNumberOfFaces()

int vtkHexahedron::GetNumberOfFaces ( )
inlineoverridevirtual

Return the number of faces in the cell.

Implements vtkCell.

Definition at line 62 of file vtkHexahedron.h.

◆ GetEdge()

vtkCell* vtkHexahedron::GetEdge ( int  edgeId)
overridevirtual

Return the edge cell from the edgeId of the cell.

Implements vtkCell.

◆ GetFace()

vtkCell* vtkHexahedron::GetFace ( int  faceId)
overridevirtual

Return the face cell from the faceId of the cell.

Implements vtkCell.

◆ CellBoundary()

int vtkHexahedron::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 vtkHexahedron::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.)

Reimplemented from vtkCell3D.

◆ EvaluatePosition()

int vtkHexahedron::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 vtkHexahedron::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.

◆ IntersectWithLine()

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

Intersect with a ray.

Return parametric coordinates (both line and cell) and global intersection coordinates, given ray definition p1[3], p2[3] and tolerance tol. The method returns non-zero value if intersection occurs. A parametric distance t between 0 and 1 along the ray representing the intersection point, the point coordinates x[3] in data coordinates and also pcoords[3] in parametric coordinates. subId is the index within the cell if a composed cell like a triangle strip.

Implements vtkCell.

◆ Triangulate()

int vtkHexahedron::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 vtkHexahedron::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* vtkHexahedron::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.

◆ GetTriangleCases()

static int* vtkHexahedron::GetTriangleCases ( int  caseId)
static

Return the case table for table-based isocontouring (aka marching cubes style implementations).

A linear 3D cell with N vertices will have 2**N cases. The returned case array lists three edges in order to produce one output triangle which may be repeated to generate multiple triangles. The list of cases terminates with a -1 entry.

◆ InterpolationFunctions()

static void vtkHexahedron::InterpolationFunctions ( const double  pcoords[3],
double  weights[8] 
)
static

◆ InterpolationDerivs()

static

◆ InterpolateFunctions()

void vtkHexahedron::InterpolateFunctions ( const double  pcoords[3],
double  weights[8]

◆ GetEdgeArray()

static int* vtkHexahedron::GetEdgeArray ( int  edgeId)
static

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

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

◆ GetFaceArray()

static int* vtkHexahedron::GetFaceArray ( int  faceId)
static

◆ JacobianInverse()

void vtkHexahedron::JacobianInverse ( const double  pcoords[3],
double **  inverse,
double  derivs[24] 
)

Given parametric coordinates compute inverse Jacobian transformation matrix.

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