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.

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.

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.) The array capacity is doubled when the inserting a cell exceeds the current capacity. extSize is no longer used.
| 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.
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.
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.

Check if BuildCells is needed.
Definition at line 267 of file vtkPolyData.h.
| 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.
| 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.

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

Get a pointer to a list of point ids defining cell.
More efficient because pointer points directly to cell array internals and this is not a virtual call. However, this requires that cells have been built (with BuildCells()). The cell type is returned.

| 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.
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.

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.

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.)
