Detailed Description

concrete dataset represents vertices, lines, polygons, and triangle strips

vtkPolyData is a data object that is a concrete implementation of vtkDataSet. vtkPolyData represents a geometric structure consisting of vertices, lines, polygons, and/or triangle strips. Point and cell attribute values (e.g., scalars, vectors, etc.) also are represented.

The actual cell types (vtkCellType.h) supported by vtkPolyData are: vtkVertex, vtkPolyVertex, vtkLine, vtkPolyLine, vtkTriangle, vtkQuad, vtkPolygon, and vtkTriangleStrip.

One important feature of vtkPolyData objects is that special traversal and data manipulation methods are available to process data. These methods are generally more efficient than vtkDataSet methods and should be used whenever possible. For example, traversing the cells in a dataset we would use GetCell(). To traverse cells with vtkPolyData we would retrieve the cell array object representing polygons (for example using GetPolys()) and then use vtkCellArray's InitTraversal() and GetNextCell() methods.

Warning
Because vtkPolyData is implemented with four separate instances of vtkCellArray to represent 0D vertices, 1D lines, 2D polygons, and 2D triangle strips, it is possible to create vtkPolyData instances that consist of a mixture of cell types. Because of the design of the class, there are certain limitations on how mixed cell types are inserted into the vtkPolyData, and in turn the order in which they are processed and rendered. To preserve the consistency of cell ids, and to ensure that cells with cell data are rendered properly, users must insert mixed cells in the order of vertices (vtkVertex and vtkPolyVertex), lines (vtkLine and vtkPolyLine), polygons (vtkTriangle, vtkQuad, vtkPolygon), and triangle strips (vtkTriangleStrip).
Some filters when processing vtkPolyData with mixed cell types may process the cells in differing ways. Some will convert one type into another (e.g., vtkTriangleStrip into vtkTriangles) or expect a certain type (vtkDecimatePro expects triangles or triangle strips; vtkTubeFilter expects lines). Read the documentation for each filter carefully to understand how each part of vtkPolyData is processed.
Some of the methods specified here function properly only when the dataset has been specified as "Editable". They are documented as such.

anonymous enum

Scalar field critical point classification (for manifold 2D meshes).

Reference: J. Milnor "Morse Theory", Princeton University Press, 1963.

Given a pointId and an attribute representing a scalar field, this member returns the index of the critical point: vtkPolyData::MINIMUM (index 0): local minimum; vtkPolyData::SADDLE (index 1): local saddle; vtkPolyData::MAXIMUM (index 2): local maximum.

Other returned values are: vtkPolyData::REGULAR_POINT: regular point (the gradient does not vanish); vtkPolyData::ERR_NON_MANIFOLD_STAR: the star of the considered vertex is not manifold (could not evaluate the index) vtkPolyData::ERR_INCORRECT_FIELD: the number of entries in the scalar field array is different form the number of vertices in the mesh. vtkPolyData::ERR_NO_SUCH_FIELD: the specified scalar field does not exist.

vtkIncrementalPointLocator locator = nullptr 
)

Copy cells listed in idList from pd, including points, point data, and cell data.

This method assumes that point and cell data have been allocated. If you pass in a point locator, then the points won't be duplicated in the output. This requires the use of an incremental point locator.

Make sure that routine BuildLinks() has been called.

Reimplemented from vtkPointSet.

◆ ComputeCellsBounds()

void vtkPolyData::ComputeCellsBounds ( )

Compute the (X, Y, Z) bounds of the data.

Note that the method only considers points that are used by cells. This is done for usability and historical reasons.

IMPORTANT

Until vtk 9.0.1, vtkPolyData::ComputeBounds() used to ignore points that do not belong to any cell. That was not consistent with other vtkPointSet subclasses and thus was error prone. See this ParaView issue https://gitlab.kitware.com/paraview/paraview/-/issues/20354 Now it defers to vtkPointSet::ComputeBounds() so vtkPolyData::GetBounds() may not return the same bounds as before. This behavior is probably the one you want when using bounds.

The previous behavior is still availble through vtkPolyData::ComputeCellsBounds() and vtkPolyData::GetCellsBounds(). This is mainly used for rendering purpose.

◆ GetCellsBounds()

void vtkPolyData::GetCellsBounds ( double  bounds[6])

Get the cells bounds.

Internally calls ComputeCellsBounds().

True if allocation succeeds.

◆ Allocate() [1/2]

void vtkPolyData::Allocate ( vtkIdType  numCells = 1000,
int   vtkNotUsedextSize = 1000 
)
inline

Method allocates initial storage for vertex, line, polygon, and triangle strip arrays.

Use this method before the method PolyData::InsertNextCell(). (Or, provide vertex, line, polygon, and triangle strip cell arrays). extSize is no longer used.

Definition at line 424 of file vtkPolyData.h.

◆ Allocate() [2/2]

void vtkPolyData::Allocate ( vtkPolyData inPolyData,
vtkIdType  numCells = 1000,
int   vtkNotUsedextSize = 1000 
)
inline

Similar to the method above, this method allocates initial storage for vertex, line, polygon, and triangle strip arrays.

It does this more intelligently, examining the supplied inPolyData to determine whether to allocate the verts, lines, polys, and strips arrays. (These arrays are allocated only if there is data in the corresponding arrays in the inPolyData.) Caution: if the inPolyData has no verts, and after allocating with this method an PolyData::InsertNextCell() is invoked where a vertex is inserted, bad things will happen.

Insert a cell of type VTK_VERTEX, VTK_POLY_VERTEX, VTK_LINE, VTK_POLY_LINE, VTK_TRIANGLE, VTK_QUAD, VTK_POLYGON, or VTK_TRIANGLE_STRIP.

Make sure that the PolyData::Allocate() function has been called first or that vertex, line, polygon, and triangle strip arrays have been supplied. Note: will also insert VTK_PIXEL, but converts it to VTK_QUAD.

◆ InsertNextCell() [2/2]

vtkIdType vtkPolyData::InsertNextCell ( int  type,
vtkIdList pts 
)

Insert a cell of type VTK_VERTEX, VTK_POLY_VERTEX, VTK_LINE, VTK_POLY_LINE, VTK_TRIANGLE, VTK_QUAD, VTK_POLYGON, or VTK_TRIANGLE_STRIP.

Make sure that the PolyData::Allocate() function has been called first or that vertex, line, polygon, and triangle strip arrays have been supplied. Note: will also insert VTK_PIXEL, but converts it to VTK_QUAD.

◆ Reset()

void vtkPolyData::Reset ( )

Begin inserting data all over again.

Memory is not freed but otherwise objects are returned to their initial state.

◆ BuildCells()

void vtkPolyData::BuildCells ( )

Create data structure that allows random access of cells.

BuildCells is expensive but necessary to make use of the faster non-virtual implementations of GetCell/GetCellPoints. One may check if cells need to be built via NeedToBuilds before invoking. Cells always need to be built/re-built after low level direct modifications to verts, lines, polys or strips cell arrays.

◆ NeedToBuildCells()

bool vtkPolyData::NeedToBuildCells ( )
inline

Check if BuildCells is needed.

Definition at line 481 of file vtkPolyData.h.

◆ BuildLinks()

void vtkPolyData::BuildLinks ( int  initialSize = 0)

Create upward links from points to cells that use each point.

Enables topologically complex queries. Normally the links array is allocated based on the number of points in the vtkPolyData. The optional initialSize parameter can be used to allocate a larger size initially.

◆ DeleteCells()

void vtkPolyData::DeleteCells ( )

Release data structure that allows random access of the cells.

This must be done before a 2nd call to BuildLinks(). DeleteCells implicitly deletes the links as well since they are no longer valid.

◆ DeleteLinks()

void vtkPolyData::DeleteLinks ( )

Release the upward links from point to cells that use each point.

◆ GetPointCells() [2/3]

void vtkPolyData::GetPointCells ( vtkIdType  ptId,
vtkIdType ncells,
vtkIdType *&  cells 
)
inline

Special (efficient) operations on poly data.

Use carefully (i.e., make sure that BuildLinks() has been called).

Definition at line 844 of file vtkPolyData.h.

◆ GetPointCells() [3/3]

void vtkPolyData::GetPointCells ( vtkIdType  ptId,
unsigned short &  ncells,
vtkIdType *&  cells 
)
inline

Special (efficient) operations on poly data.

Use carefully (i.e., make sure that BuildLinks() has been called).

Definition at line 850 of file vtkPolyData.h.

◆ GetCellEdgeNeighbors()

void vtkPolyData::GetCellEdgeNeighbors ( vtkIdType  cellId,
vtkIdType  p1,
vtkIdType  p2,
vtkIdList cellIds 
)

Get the neighbors at an edge.

More efficient than the general GetCellNeighbors(). Assumes links have been built (with BuildLinks()), and looks specifically for edge neighbors.

◆ GetCellPoints() [2/2]

unsigned char vtkPolyData::GetCellPoints ( vtkIdType  cellId,
vtkIdType npts,
vtkIdType const *&  pts 
)
inline

Get a list of point ids that define a cell.

The cell type is returned. Requires the the cells have been built with BuildCells.

Warning
Subsequent calls to this method may invalidate previous call results.

The pts pointer must not be modified.

Definition at line 1000 of file vtkPolyData.h.

◆ IsTriangle()

int vtkPolyData::IsTriangle ( int  v1,
int  v2,
int  v3 
)
inline

Given three vertices, determine whether it's a triangle.

Make sure BuildLinks() has been called first.

Definition at line 875 of file vtkPolyData.h.

◆ IsEdge()

int vtkPolyData::IsEdge ( vtkIdType  p1,
vtkIdType  p2 
)

Determine whether two points form an edge.

If they do, return non-zero. By definition PolyVertex and PolyLine have no edges since 1-dimensional edges are only found on cells 2D and higher. Edges are defined as 1-D boundary entities to cells. Make sure BuildLinks() has been called first.

◆ IsPointUsedByCell()

int vtkPolyData::IsPointUsedByCell ( vtkIdType  ptId,
vtkIdType  cellId 
)
inline

Determine whether a point is used by a particular cell.

If it is, return non-zero. Make sure BuildCells() has been called first.

Definition at line 905 of file vtkPolyData.h.

◆ ReplaceCell() [1/2]

void vtkPolyData::ReplaceCell ( vtkIdType  cellId,
vtkIdList ids 
)

Replace the points defining cell "cellId" with a new set of points.

This operator is (typically) used when links from points to cells have not been built (i.e., BuildLinks() has not been executed). Use the operator ReplaceLinkedCell() to replace a cell when cell structure has been built. Use this method only when the dataset is set as Editable.

◆ ReplaceCell() [2/2]

void vtkPolyData::ReplaceCell ( vtkIdType  cellId,
int  npts,
const vtkIdType  pts[] 
)

Replace the points defining cell "cellId" with a new set of points.

This operator is (typically) used when links from points to cells have not been built (i.e., BuildLinks() has not been executed). Use the operator ReplaceLinkedCell() to replace a cell when cell structure has been built. Use this method only when the dataset is set as Editable.

◆ ReplaceCellPoint()

void vtkPolyData::ReplaceCellPoint ( vtkIdType  cellId,
vtkIdType  oldPtId,
vtkIdType  newPtId 
)
inline

Use this method only when the dataset is set as Editable.

Definition at line 984 of file vtkPolyData.h.

◆ ReverseCell()

void vtkPolyData::ReverseCell ( vtkIdType  cellId)

Reverse the order of point ids defining the cell.

Use this method only when the dataset is set as Editable.

◆ DeletePoint()

void vtkPolyData::DeletePoint ( vtkIdType  ptId)
inline

Mark a point/cell as deleted from this vtkPolyData.

Use this method only when the dataset is set as Editable.

Definition at line 923 of file vtkPolyData.h.

◆ DeleteCell()

void vtkPolyData::DeleteCell ( vtkIdType  cellId)
inline

Mark a point/cell as deleted from this vtkPolyData.

Use this method only when the dataset is set as Editable.

Definition at line 929 of file vtkPolyData.h.

◆ RemoveDeletedCells()

void vtkPolyData::RemoveDeletedCells ( )

The cells marked by calls to DeleteCell are stored in the Cell Array VTK_EMPTY_CELL, but they still exist in the cell arrays.

Calling RemoveDeletedCells will traverse the cell arrays and remove/compact the cell arrays as well as any cell data thus truly removing the cells from the polydata object. Use this method only when the dataset is set as Editable.

◆ InsertNextLinkedPoint() [1/2]

vtkIdType vtkPolyData::InsertNextLinkedPoint ( int  numLinks)

Add a point to the cell data structure (after cell pointers have been built).

This method adds the point and then allocates memory for the links to the cells. (To use this method, make sure points are available and BuildLinks() has been invoked.) Of the two methods below, one inserts a point coordinate and the other just makes room for cell links. Use this method only when the dataset is set as Editable.

◆ InsertNextLinkedPoint() [2/2]

vtkIdType vtkPolyData::InsertNextLinkedPoint ( double  x[3],
int  numLinks 
)

Add a point to the cell data structure (after cell pointers have been built).

This method adds the point and then allocates memory for the links to the cells. (To use this method, make sure points are available and BuildLinks() has been invoked.) Of the two methods below, one inserts a point coordinate and the other just makes room for cell links. Use this method only when the dataset is set as Editable.

◆ InsertNextLinkedCell()

vtkIdType vtkPolyData::InsertNextLinkedCell ( int  type,
int  npts,
const vtkIdType  pts[] 
)

Add a new cell to the cell data structure (after cell pointers have been built).

This method adds the cell and then updates the links from the points to the cells. (Memory is allocated as necessary.) Use this method only when the dataset is set as Editable.

◆ ReplaceLinkedCell()

void vtkPolyData::ReplaceLinkedCell ( vtkIdType  cellId,
int  npts,
const vtkIdType  pts[] 
)

Replace one cell with another in cell structure.

This operator updates the connectivity list and the point's link list. It does not delete references to the old cell in the point's link list. Use the operator RemoveCellReference() to delete all references from points to (old) cell. You may also want to consider using the operator ResizeCellList() if the link list is changing size. Use this method only when the dataset is set as Editable.

◆ RemoveCellReference()

void vtkPolyData::RemoveCellReference ( vtkIdType  cellId)
inline

Remove all references to cell in cell structure.

This means the links from the cell's points to the cell are deleted. Memory is not reclaimed. Use the method ResizeCellList() to resize the link list from a point to its using cells. (This operator assumes BuildLinks() has been called.) Use this method only when the dataset is set as Editable.

Definition at line 935 of file vtkPolyData.h.

◆ AddCellReference()

void vtkPolyData::AddCellReference ( vtkIdType  cellId)
inline

Add references to cell in cell structure.

This means the links from the cell's points to the cell are modified. Memory is not extended. Use the method ResizeCellList() to resize the link list from a point to its using cells. (This operator assumes BuildLinks() has been called.) Use this method only when the dataset is set as Editable.

Definition at line 948 of file vtkPolyData.h.

◆ RemoveReferenceToCell()

void vtkPolyData::RemoveReferenceToCell ( vtkIdType  ptId,
vtkIdType  cellId 
)

Remove a reference to a cell in a particular point's link list.

You may also consider using RemoveCellReference() to remove the references from all the cell's points to the cell. This operator does not reallocate memory; use the operator ResizeCellList() to do this if necessary. Use this method only when the dataset is set as Editable.

◆ AddReferenceToCell()

void vtkPolyData::AddReferenceToCell ( vtkIdType  ptId,
vtkIdType  cellId 
)

Add a reference to a cell in a particular point's link list.

(You may also consider using AddCellReference() to add the references from all the cell's points to the cell.) This operator does not realloc memory; use the operator ResizeCellList() to do this if necessary. Use this method only when the dataset is set as Editable.

◆ ResizeCellList()

void vtkPolyData::ResizeCellList ( vtkIdType  ptId,
int  size 
)
inline

Resize the list of cells using a particular point.

(This operator assumes that BuildLinks() has been called.) Use this method only when the dataset is set as Editable.

Definition at line 961 of file vtkPolyData.h.

const char *  fieldName 
)

◆ GetMeshMTime()

virtual vtkMTimeType vtkPolyData::GetMeshMTime ( )
virtual

Return the mesh (geometry/topology) modification time.

This time is different from the usual MTime which also takes into account the modification of data arrays. This function can be used to track the changes on the mesh separately from the data arrays (eg. static mesh over time with transient data).

◆ GetMTime()

vtkMTimeType vtkPolyData::GetMTime ( )
overridevirtual

Get MTime which also considers its cell array MTime.

Reimplemented from vtkPointSet.

unsigned char vtkPolyData::GetCell ( vtkIdType  cellId,
const vtkIdType *&  pts 
)

Get a pointer to the cell, ie [npts pid1 .

. pidn]. The cell type is returned. Requires the the cells have been built with BuildCells. The pts pointer must not be modified.

Warning
Internal cell storage has changed, and cell size is no longer stored with the cell point ids. The pts array returned here no longer exists in memory.

◆ GetCellArrayInternal()

vtkCellArray * vtkPolyData::GetCellArrayInternal ( vtkPolyData::TaggedCellId  tag)
inlineprotected

Definition at line 967 of file vtkPolyData.h.

◆ GetCell() [4/6]

virtual vtkCell * vtkDataSet::GetCell ( vtkIdType  cellId)
virtual

Get cell with cellId such that: 0 <= cellId < NumberOfCells.

The returned vtkCell is an object owned by this instance, hence the return value must not be deleted by the caller.

Warning
Repeat calls to this function for different face ids will change the data stored in the internal member object whose pointer is returned by this function.
THIS METHOD IS NOT THREAD SAFE. For a thread-safe version, please use void GetCell(vtkIdType cellId, vtkGenericCell* cell).

Reimplemented from vtkPointSet.

◆ GetCell() [5/6]
