Member Function Documentation

static vtkBridgeDataSet* vtkBridgeDataSet::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkDataObject.

virtual const char* vtkBridgeDataSet::GetClassName ( ) [virtual]

Standard VTK type and print macros.

Reimplemented from vtkGenericDataSet.

static int vtkBridgeDataSet::IsTypeOf ( const char * type ) [static]

Standard VTK type and print macros.

Reimplemented from vtkGenericDataSet.

virtual int vtkBridgeDataSet::IsA ( const char * type ) [virtual]

Standard VTK type and print macros.

Reimplemented from vtkGenericDataSet.

static vtkBridgeDataSet* vtkBridgeDataSet::SafeDownCast ( vtkObject * o ) [static]

Standard VTK type and print macros.

Reimplemented from vtkGenericDataSet.

void vtkBridgeDataSet::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Standard VTK type and print macros.

Reimplemented from vtkGenericDataSet.

vtkDataSet* vtkBridgeDataSet::GetDataSet ( )

Return the dataset that will be manipulated through the adaptor interface.

void vtkBridgeDataSet::SetDataSet ( vtkDataSet * ds )

Set the dataset that will be manipulated through the adaptor interface.

Precondition:: ds_exists: ds!=0

virtual vtkIdType vtkBridgeDataSet::GetNumberOfPoints ( ) [virtual]

Number of points composing the dataset. See NewPointIterator for more details.

Postcondition:: positive_result: result>=0

Implements vtkGenericDataSet.

virtual vtkIdType vtkBridgeDataSet::GetNumberOfCells ( int dim = -1 ) [virtual]

Number of cells that explicitly define the dataset. See NewCellIterator for more details.

Precondition:: valid_dim_range: (dim>=-1) && (dim<=3)

Postcondition:: positive_result: result>=0

Implements vtkGenericDataSet.

virtual int vtkBridgeDataSet::GetCellDimension ( ) [virtual]

Return -1 if the dataset is explicitly defined by cells of several dimensions or if there is no cell. If the dataset is explicitly defined by cells of a unique dimension, return this dimension.

Postcondition:: valid_range: (result>=-1) && (result<=3)

Implements vtkGenericDataSet.

void vtkBridgeDataSet::GetCellTypes ( vtkCellTypes * types ) [virtual]

Get a list of types of cells in a dataset. The list consists of an array of types (not necessarily in any order), with a single entry per type. For example a dataset 5 triangles, 3 lines, and 100 hexahedra would result a list of three entries, corresponding to the types VTK_TRIANGLE, VTK_LINE, and VTK_HEXAHEDRON. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Precondition:: types_exist: types!=0

Reimplemented from vtkGenericDataSet.

vtkGenericCellIterator* vtkBridgeDataSet::NewCellIterator ( int dim = -1 ) [virtual]

Cells of dimension `dim' (or all dimensions if -1) that explicitly define the dataset. For instance, it will return only tetrahedra if the mesh is defined by tetrahedra. If the mesh is composed of two parts, one with tetrahedra and another part with triangles, it will return both, but will not return edges and vertices.

Precondition:: valid_dim_range: (dim>=-1) && (dim<=3)

Postcondition:: result_exists: result!=0

Implements vtkGenericDataSet.

vtkGenericCellIterator* vtkBridgeDataSet::NewBoundaryIterator	(	int	dim = `-1`,
		int	exteriorOnly = `0`
	)			`[virtual]`

Boundaries of dimension `dim' (or all dimensions if -1) of the dataset. If `exteriorOnly' is true, only the exterior boundaries of the dataset will be returned, otherwise it will return exterior and interior boundaries.

Precondition:: valid_dim_range: (dim>=-1) && (dim<=2)

Postcondition:: result_exists: result!=0

Implements vtkGenericDataSet.

vtkGenericPointIterator* vtkBridgeDataSet::NewPointIterator ( ) [virtual]

Points composing the dataset; they can be on a vertex or isolated.

Postcondition:: result_exists: result!=0

Implements vtkGenericDataSet.

vtkIdType vtkBridgeDataSet::GetEstimatedSize ( ) [virtual]

Estimated size needed after tessellation (or special operation)

Implements vtkGenericDataSet.

int vtkBridgeDataSet::FindCell	(	double	x[3],
		vtkGenericCellIterator *&	cell,
		double	tol2,
		int &	subId,
		double	pcoords[3]
	)			`[virtual]`

Locate closest cell to position `x' (global coordinates) with respect to a tolerance squared `tol2' and an initial guess `cell' (if valid). The result consists in the `cell', the `subId' of the sub-cell (0 if primary cell), the parametric coordinates `pcoord' of the position. It returns whether the position is inside the cell or not. Tolerance is used to control how close the point is to be considered "in" the cell. THIS METHOD IS NOT THREAD SAFE.

Precondition:

not_empty: GetNumberOfCells()>0

cell_exists: cell!=0

positive_tolerance: tol2>0

Implements vtkGenericDataSet.
