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 insure 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.

anonymous enum

Scalar field critical point classification (for manifold 2D meshes). Reference: J. Milnor "Morse Theory", Princeton University Press,

  1. 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.

Reimplemented from vtkPointSet.

◆ GetDataObjectType()

int vtkPolyData::GetDataObjectType ( )
inlinevirtual

Return what type of dataset this is.

Reimplemented from vtkDataSet.

Definition at line 92 of file vtkPolyData.h.

◆ CopyStructure()

void vtkPolyData::CopyStructure ( vtkDataSet *  ds)
virtual

Copy the geometric and topological structure of an input poly data object.

Reimplemented from vtkPointSet.

◆ GetNumberOfCells()

vtkIdType vtkPolyData::GetNumberOfCells ( )
virtual

Standard vtkDataSet interface.

Implements vtkDataSet.

◆ GetCell() [1/2]

vtkCell* vtkPolyData::GetCell ( vtkIdType  cellId)
virtual

Get cell with cellId such that: 0 <= cellId < NumberOfCells. THIS METHOD IS NOT THREAD SAFE.

Implements vtkDataSet.

◆ GetCell() [2/2]

void vtkPolyData::GetCell ( vtkIdType  cellId,
vtkGenericCell *  cell 
)
virtual

Get cell with cellId such that: 0 <= cellId < NumberOfCells. This is a thread-safe alternative to the previous GetCell() method. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

◆ GetCellType()

int vtkPolyData::GetCellType ( vtkIdType  cellId)
virtual

Get type of cell with cellId such that: 0 <= cellId < NumberOfCells. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

◆ GetCellBounds()

void vtkPolyData::GetCellBounds ( vtkIdType  cellId,
double  bounds[6] 
)
virtual

Get the bounds of the cell with cellId such that: 0 <= cellId < NumberOfCells. A subclass may be able to determine the bounds of cell without using an expensive GetCell() method. A default implementation is provided that actually uses a GetCell() call. This is to ensure the method is available to all datasets. Subclasses should override this method to provide an efficient implementation. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Reimplemented from vtkDataSet.

◆ GetCellNeighbors()

void vtkPolyData::GetCellNeighbors ( vtkIdType  cellId,
vtkIdList *  ptIds,
vtkIdList *  cellIds 
)
virtual

Topological inquiry to get all cells using list of points exclusive of cell specified (e.g., cellId). Note that the list consists of only cells that use ALL the points provided. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Reimplemented from vtkDataSet.

◆ CopyCells()

void vtkPolyData::CopyCells ( vtkPolyData *  pd,
vtkIdList *  idList,
vtkPointLocator *  locator = NULL 
)

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.

◆ GetCellPoints() [1/2]

void vtkPolyData::GetCellPoints ( vtkIdType  cellId,
vtkIdList *  ptIds 
)
virtual

Copy a cells point ids into list provided. (Less efficient.)

◆ Allocate() [2/2]

void vtkPolyData::Allocate ( vtkPolyData *  inPolyData,
vtkIdType  numCells = 1000,
int  extSize = 1000 
)

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.

◆ InsertNextCell() [1/2]

vtkIdType vtkPolyData::InsertNextCell ( int  type,
int  npts,
vtkIdType *  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.

◆ 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.

◆ 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() [2/2]

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

Special (efficient) operations on poly data. Use carefully.

Definition at line 468 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]

void vtkPolyData::GetCellPoints ( vtkIdType  cellId,
vtkIdType &  npts,
vtkIdType *&  pts 
)

Return a pointer to a list of point ids defining cell. (More efficient.) Assumes that cells have been built (with BuildCells()).

◆ 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 475 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 505 of file vtkPolyData.h.

◆ ReplaceCell()

void vtkPolyData::ReplaceCell ( vtkIdType  cellId,
int  npts,
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.

◆ ReplaceCellPoint()

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

Replace a point in the cell connectivity list with a different point.

Definition at line 558 of file vtkPolyData.h.

◆ ReverseCell()

void vtkPolyData::ReverseCell ( vtkIdType  cellId)

Reverse the order of point ids defining the cell.

◆ DeletePoint()

void vtkPolyData::DeletePoint ( vtkIdType  ptId)
inline

Mark a point/cell as deleted from this vtkPolyData.

Definition at line 521 of file vtkPolyData.h.

◆ DeleteCell()

void vtkPolyData::DeleteCell ( vtkIdType  cellId)
inline

Definition at line 526 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.

◆ 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.

◆ InsertNextLinkedPoint() [2/2]

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

◆ InsertNextLinkedCell()

vtkIdType vtkPolyData::InsertNextLinkedCell ( int  type,
int  npts,
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.)

◆ ReplaceLinkedCell()

void vtkPolyData::ReplaceLinkedCell ( vtkIdType  cellId,
int  npts,
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.

◆ 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.)

Definition at line 531 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.)

Definition at line 542 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.

◆ 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.

◆ 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.)

Definition at line 553 of file vtkPolyData.h.

◆ Initialize()

virtual void vtkPolyData::Initialize ( )
virtual

Restore object to initial state. Release memory back to system.

Reimplemented from vtkPointSet.

◆ GetPiece()

virtual int vtkPolyData::GetPiece ( )
virtual

Get the piece and the number of pieces. Similar to extent in 3D.

◆ GetNumberOfPieces()

virtual int vtkPolyData::GetNumberOfPieces ( )
virtual

◆ GetGhostLevel()

virtual int vtkPolyData::GetGhostLevel ( )
virtual

Get the ghost level.

◆ GetActualMemorySize()

unsigned long vtkPolyData::GetActualMemorySize ( )
virtual

Return the actual size of the data in kibibytes (1024 bytes). This number is valid only after the pipeline has updated. The memory size returned is guaranteed to be greater than or equal to the memory required to represent the data (e.g., extra space in arrays, etc. are not included in the return value). THIS METHOD IS THREAD SAFE.

Reimplemented from vtkPointSet.

◆ ShallowCopy()

void vtkPolyData::ShallowCopy ( vtkDataObject *  src)
virtual

Shallow and Deep copy.

Reimplemented from vtkPointSet.

◆ DeepCopy()

void vtkPolyData::DeepCopy ( vtkDataObject *  src)
virtual

Reimplemented from vtkPointSet.

◆ RemoveGhostCells()

void vtkPolyData::RemoveGhostCells ( )

This method will remove any cell that is marked as ghost (has the vtkDataSetAttributes::DUPLICATECELL bit set). It does not remove unused points.
