Detailed Description

a cell that represents a 3D orthogonal parallelepiped

vtkVoxel is a concrete implementation of vtkCell to represent a 3D orthogonal parallelepiped. Unlike vtkHexahedron, vtkVoxel has interior angles of 90 degrees, and sides are parallel to coordinate axes. This results in large increases in computational performance.

Implements vtkCell.

◆ Inflate()

int vtkVoxel::Inflate ( double  dist)
overridevirtual

Inflates voxel by moving every faces by dist.

Since normals are not ambiguous for degenerate voxels, degenerate voxels are inflated correctly. For example, inflating a voxel collapsed to a single point will produce a voxel of width 2 * dist.

Returns
1

Reimplemented from vtkCell3D.

◆ InterpolationDerivs()

static void vtkVoxel::InterpolationDerivs ( const double  pcoords[3],
double  derivs[24] 
)
static

◆ InterpolateFunctions()

void vtkVoxel::InterpolateFunctions ( const double  pcoords[3],
double  weights[8] 
)
inlineoverride

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

Definition at line 142 of file vtkVoxel.h.

◆ InterpolateDerivs()

void vtkVoxel::InterpolateDerivs ( const double  pcoords[3],
double  derivs[24] 
)
inlineoverride

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

Definition at line 146 of file vtkVoxel.h.

◆ InterpolationFunctions()

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

Compute the interpolation functions.

This static method is for convenience. Use the member function if you already have an instance of a voxel.

◆ GetTriangleCases()

static int* vtkVoxel::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.

◆ GetEdgeArray()

static const vtkIdType* vtkVoxel::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, and so vtkCell ids can be used as inputs in algorithms such as vtkPolygon::ComputeNormal.

◆ GetFaceArray()

static const vtkIdType* vtkVoxel::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, and so vtkCell ids can be used as inputs in algorithms such as vtkPolygon::ComputeNormal.

◆ GetEdgeToAdjacentFacesArray()

static const vtkIdType* vtkVoxel::GetEdgeToAdjacentFacesArray ( vtkIdType  edgeId)
static

Static method version of GetEdgeToAdjacentFaces.

◆ GetFaceToAdjacentFacesArray()

static const vtkIdType* vtkVoxel::GetFaceToAdjacentFacesArray ( vtkIdType  faceId)
static

Static method version of GetFaceToAdjacentFaces.

◆ GetPointToIncidentEdgesArray()

static const vtkIdType* vtkVoxel::GetPointToIncidentEdgesArray ( vtkIdType  pointId)
static

Static method version of GetPointToIncidentEdgesArray.

◆ GetPointToIncidentFacesArray()

static const vtkIdType* vtkVoxel::GetPointToIncidentFacesArray ( vtkIdType  pointId)
static

Static method version of GetPointToIncidentFacesArray.

◆ GetPointToOneRingPointsArray()

static const vtkIdType* vtkVoxel::GetPointToOneRingPointsArray ( vtkIdType  pointId)
static

Static method version of GetPointToOneRingPoints.

◆ ComputeCentroid()

static bool vtkVoxel::ComputeCentroid ( vtkPoints points,
const vtkIdType pointIds,
double  centroid[3] 
)
static

Static method version of GetCentroid.

◆ MaximumFaceSize

constexpr vtkIdType vtkVoxel::MaximumFaceSize = 4
staticconstexpr

static contexpr handle on the maximum face size.

It can also be used to know the number of faces adjacent to one face.

Definition at line 93 of file vtkVoxel.h.

◆ MaximumValence

constexpr vtkIdType vtkVoxel::MaximumValence = 3
staticconstexpr

static constexpr handle on the maximum valence of this cell.

The valence of a vertex is the number of incident edges (or equivalently faces) to this vertex. It is also equal to the size of a one ring neighborhood of a vertex.
