## 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.

|  | 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.

void vtkPolyData::GetCellPoints | ( | vtkIdType | cellId,
|  | vtkIdList * | ptIds
| ) | `[virtual]`

| Copy a cells point ids into list provided. (Less efficient.) Implements vtkDataSet. Referenced by AddCellReference(), IsPointUsedByCell(), IsTriangle(), RemoveCellReference(), and ReplaceCellPoint().

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]`

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. Definition at line 442 of file vtkPolyData.h. References GetCellPoints(), GetPointCells(), and vtkIdType.

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. Definition at line 488 of file vtkPolyData.h. References GetPointCells(), IsPointUsedByCell(), and vtkIdType.

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 472 of file vtkPolyData.h. References GetCellPoints(), and vtkIdType. Referenced by IsEdge().

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 543 of file vtkPolyData.h. References GetCellPoints(), and vtkIdType.

void vtkPolyData::ReverseCell | ( | vtkIdType | cellId | ) |

| Reverse the order of point ids defining the cell.

void vtkPolyData::DeletePoint | ( | vtkIdType | ptId | ) | `[inline]`

| Mark a point/cell as deleted from this vtkPolyData. Definition at line 506 of file vtkPolyData.h. References vtkCellLinks::DeletePoint(), Links, and vtkIdType.

void vtkPolyData::DeleteCell | ( | vtkIdType | cellId | ) | `[inline]`

| Mark a point/cell as deleted from this vtkPolyData. 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
| ) | `[inline]`

| Resize the list of cells using a particular point. (This operator assumes that BuildLinks() has been called.) Definition at line 538 of file vtkPolyData.h. References Links, vtkCellLinks::ResizeCellList(), and vtkIdType.

void vtkPolyData::SetUpdateExtent | ( | int | piece,
|  | int | numPieces,

| ) | `[inline]`

| For streaming. User/next filter specifies which piece they want updated. The source of this poly data has to return exactly this piece. Reimplemented from vtkDataObject. Definition at line 334 of file vtkPolyData.h. References vtkDataObject::SetUpdateExtent().

|  | int | y1,
|  | int | y2,
|  | int | z1,
|  | int | z2
| ) | `[inline, virtual]`

| Call superclass method to avoid hiding Since this data type does not use 3D extents, this set method is useless but necessary since vtkDataSetToDataSetFilter does not know what type of data it is working on. Reimplemented from vtkDataObject. Definition at line 349 of file vtkPolyData.h. References vtkDataObject::SetUpdateExtent().

unsigned long vtkPolyData::GetActualMemorySize | ( |  | ) | `[virtual]`

| Return the actual size of the data in kilobytes. 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).
