Detailed Description

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

Date:: 2002/12/26 18:24:21

Revision:: 1.122

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

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

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) and then use vtkCellArray's InitTraversal() and GetNextCell() methods.

void vtkPolyData::Allocate ( vtkIdType numCells = 1000,

int extSize = 1000

)

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.)

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.

int vtkPolyData::InsertNextCell ( int type,

int npts,

vtkIdType * pts

)

Insert a cell of type vtkVERTEX, vtkPOLY_VERTEX, vtkLINE, vtkPOLY_LINE, vtkTRIANGLE, vtkQUAD, vtkPOLYGON, or vtkTRIANGLE_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 vtkPIXEL, but converts it to vtkQUAD.

int 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.

void vtkPolyData::Reset ( )

Begin inserting data all over again. Memory is not freed but otherwise objects are returned to their initial state.

void vtkPolyData::BuildCells ( )

Create data structure that allows random access of cells.

void vtkPolyData::BuildLinks ( )

Create upward links from points to cells that use each point. Enables topologically complex queries.

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.

void vtkPolyData::DeleteLinks ( )

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

void vtkPolyData::GetPointCells ( vtkIdType ptId,

unsigned short & ncells,

vtkIdType *& cells

) [inline]

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

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.

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()).

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.

int vtkPolyData::IsEdge ( int v1,

int v2

) [inline]

Determine whether two points form an edge. If they do, return non-zero. Make sure BuildLinks() has been called first.

References GetPointCells(), IsPointUsedByCell(), and vtkIdType.

int vtkPolyData::IsPointUsedByCell ( vtkIdType ptId,

) [inline]

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.

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 511 of file vtkPolyData.h.
References Cells, vtkCellTypes::DeleteCell(), and vtkIdType.

int vtkPolyData::InsertNextLinkedPoint ( float 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.)

int 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.)

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.

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 516 of file vtkPolyData.h.
References GetCellPoints(), Links, vtkCellLinks::RemoveCellReference(), and vtkIdType.

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 527 of file vtkPolyData.h.
References vtkCellLinks::AddCellReference(), GetCellPoints(), Links, and vtkIdType.

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.

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.

void vtkPolyData::ResizeCellList ( vtkIdType ptId,

int size

Resize the list of cells using a particular point. (This operator assumes that BuildLinks() has been called.)
