Detailed Description

A 3D cell defined by a set of polygonal faces.

Instantiation

vtkPolyhedron is a concrete implementation of vtkCell that represents a 3D cell defined by a set of polygonal faces.

To instantiate a vtkPolyhedron, like any vtkCell, one needs to define the following structures:

Note that the ordering of points coordinates or IDs is not important. However, it MUST be consistent between the two lists.

Unlike other kinds of cells (e.g. vtkVoxel), the topology is not directly deduced from points coordinates or point IDs ordering; it must be explicitly defined by providing a list of faces (see the SetFaces() method). Each face is represented as a sequence of global point Ids.

Once point coordinates, point IDs and faces are defined, the Initialize() method should be called in order to setup the internal structures and finalize the construction of the polyhedron.

Here is an example of vtkPolyhedron instantiation:

// 9 +------+.11
// |`. | `.
// |13`+--+---+ 15
// | | | |
// 8 +---+--+.10|
// `. | `.|
// 12`+------+ 14
//
// (Global IDs are arbitrarily chosen between 8 and 15)
// Insert point coordinates
polyhedron->GetPoints()->SetNumberOfPoints(8);
polyhedron->GetPoints()->SetPoint(0, 0., 0., 0.); // 8
polyhedron->GetPoints()->SetPoint(1, 0., 1., 0.); // 9
polyhedron->GetPoints()->SetPoint(2, 1., 0., 0.); // 10
polyhedron->GetPoints()->SetPoint(3, 1., 1., 0.); // 11
polyhedron->GetPoints()->SetPoint(4, 0., 0., 1.); // 12
polyhedron->GetPoints()->SetPoint(5, 0., 1., 1.); // 13
polyhedron->GetPoints()->SetPoint(6, 1., 0., 1.); // 14
polyhedron->GetPoints()->SetPoint(7, 1., 1., 1.); // 15
// Insert point IDs (global IDs)
// Note that the canonical ordering (0, 1, ..., 8) is used
// to correlate point Ids and coordinates
polyhedron->GetPointIds()->Allocate(8);
for (int i = 8; i < 16; ++i)
{
polyhedron->GetPointIds()->InsertNextId(i);
}
// Describe faces, indexed on global IDs
vtkIdType faces[31] = { 6, // Number of faces
4, 9 , 11, 10, 8 , // Number of points in the face + point IDs
4, 11, 15, 14, 10, // Faces are described counter-clockwise
4, 15, 13, 12, 14, // looking from the "outside" of the cell
4, 13, 9 , 8 , 12,
4, 14, 12, 8 , 10,
4, 13, 15, 11, 9 };

Specifications

Polyhedrons described by this class must conform to some criteria in order to avoid errors and guarantee good results in terms of visualization and processing.

These specifications are described as follows. Polyhedrons must:

In a more global perspective, polyhedrons must be watertight and manifold. In particular, each edge of the polyhedron must be adjacent to exactly two faces. Several algorithms like contour, clip or slice will assume that each edge of the polyhedron is adjacent to exactly two faces and will definitely lead to bad results (and generate numerous warnings) if this criterion is not fulfilled.

Limitations

The class does not require the polyhedron to be convex. However, the support of concave polyhedrons is currently limited. Concavity can lead to bad results with some filters, including:

Other details

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

vtkCellArray polys,
vtkPointData inPd,
vtkPointData outPd,
vtkCellData inCd,
vtkIdType  cellId,

)
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.

Warning
The current implementation assumes water-tight and manifold polyhedron cells.

Reimplemented from vtkCell3D.

◆ Clip()

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.

◆ EvaluateLocation()

void vtkPolyhedron::EvaluateLocation ( int &  subId,

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.

◆ TriangulateLocalIds()

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

Use vtkOrderedTriangulator to tetrahedralize the polyhedron mesh.

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.

Warning
This method works well for a convex polyhedron but may return wrong result in a concave case.

Implements vtkCell.

◆ TriangulateFaces() [1/2]

int vtkPolyhedron::TriangulateFaces ( vtkIdList newFaces)

Triangulate each face of the polyhedron.

This method internally use the vtkCell::Triangulate method on each face (so the triangulation method vary depending on the 2D cell type corresponding to the face).

Warning
Can lead to bad results with non-planar faces.

◆ TriangulateFaces() [2/2]

int vtkPolyhedron::TriangulateFaces ( vtkCellArray newFaces)

Triangulate each face of the polyhedron.

This method internally use the vtkCell::Triangulate method on each face (so the triangulation method vary depending on the 2D cell type corresponding to the face).

Warning
Can lead to bad results with non-planar faces.

◆ Derivatives()

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.

◆ CellBoundary()

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.

◆ GetParametricCenter()

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

◆ InterpolateFunctions()

void vtkPolyhedron::InterpolateFunctions ( const double  x[3],
double *  sf 
)
override

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

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

◆ InterpolateDerivs()

void vtkPolyhedron::InterpolateDerivs ( const double  x[3],
double *  derivs 
)
override

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

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

◆ RequiresExplicitFaceRepresentation()

int vtkPolyhedron::RequiresExplicitFaceRepresentation ( )
inlineoverridevirtual

Satisfy the vtkCell API.

Always return true, because vtkPolyhedron needs explicit faces definition in order to describe the topology of the cell.

Reimplemented from vtkCell.

Definition at line 379 of file vtkPolyhedron.h.

◆ SetFaces()

void vtkPolyhedron::SetFaces ( vtkIdType faces)
override

Set the faces of the polyhedron.

Face are expressed as sequences of global point IDs . The SetFaces method will require a copy from internal unstructured grid layout.

Parameters
faces1-dimensional array with the following structure :
[ NbOfFaces,
NbOfPtsFace1, face1Pt1, face1Pt2, …, face1PtNbOfPtsFace1,
NbOfPtsFace2, face2Pt1, face2Pt2, …, face2PtNbOfPtsFace2,
…,
NbOfPtsFaceN, faceNPt1, faceNPt2, …, faceNPtNbOfPtsFaceN ]
This ordering corresponds to the legacy vtkCellArray form, with in addition a leading count indicating the total number of faces in the list.

◆ GetFaces()

vtkIdType * vtkPolyhedron::GetFaces ( )
overridevirtual

Get the faces of the polyhedron.

Face are expressed as sequences of global point IDs .

Returns
A 1-dimentional array with the following structure :

NbOfPtsFace2, face2Pt1, face2Pt2, …, face2PtNbOfPtsFace2,
…,
NbOfPtsFaceN, faceNPt1, faceNPt2, …, faceNPtNbOfPtsFaceN ]
This ordering corresponds to the legacy vtkCellArray form. Note that unlike the SetFaces method, the total faces number leading count is missing. In order to get the number of faces, please use the vtkPolyhedron::GetNumberOfFaces() method.

Reimplemented from vtkCell.

◆ SetCellFaces()

◆ IsInside()

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.

◆ IsConvex()

bool vtkPolyhedron::IsConvex ( )
