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.

◆ CopyCells()

		vtkIdList *	idList,
		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.

◆ GetCellPoints() [1/2]

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().

See also: ComputeCellsBounds()

vtkIdType vtkPolyData::GetCellIdRelativeToCellArray ( vtkIdType cellId )

Maps the cell at position cellId inside the vtkPolyData to its location in the corresponding cell array.

For instance, if cell cellId is a line, then this method returns the position of this cell in the Lines cell array.

◆ GetLines()

vtkCellArray * vtkPolyData::GetLines ( )
