Member Function Documentation

int SMDS_Downward::addCell ( int vtkId = -1 ) [protected, inherited]

Give or create an entry for downward connectivity structure relative to a cell.

If the entry already exists, just return its id, otherwise, create it. The internal storage memory is allocated if needed. The SMDS_UnstructuredGrid._cellIdToDownId vector is completed for vtkUnstructuredGrid cells.

Parameters:

vtkId for a vtkUnstructuredGrid cell or -1 (default) for a created downward cell.

Returns:: the rank in downward[vtkType] structure.

		unsigned char	aType
	)		`[protected, virtual, inherited]`

Id's are downward connectivity id's.

add a downward entity of dimension n-1 (cell or node) to a given cell.

Actual implementation is done in derived methods.

Parameters:

cellId	index of the parent cell (dimension n) in the downward structure relative to a vtk cell type.
lowCellId	index of the children cell to add (dimension n-1)
aType	vtk cell type of the cell to add (needed to find the SMDS_Downward structure containing the cell to add).

Reimplemented in SMDS_DownTriangle, SMDS_DownQuadTriangle, SMDS_DownQuadrangle, SMDS_DownQuadQuadrangle, SMDS_DownTetra, SMDS_DownQuadTetra, SMDS_DownPyramid, SMDS_DownQuadPyramid, SMDS_DownPenta, SMDS_DownQuadPenta, SMDS_DownHexa, and SMDS_DownQuadHexa.

void SMDS_Downward::addUpCell	(	int	cellId,
		int	upCellId,

	)		`[protected, virtual, inherited]`

Id's are downward connectivity id's.

Actual implementation is done in derived methods.

Parameters:
