Member Function Documentation

int SMDS_Downward::addCell ( int  vtkId = -1 )

protectedinherited

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.

void SMDS_Downward::addDownCell ( int  cellId, int  lowCellId, unsigned char  aType  )

protectedvirtualinherited

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).
