Detailed Description

List of extracted structured surface cells interface.

A generic abstract interface for an extracted structured implicit surface mesh topology. Cells are all implicitly defined as quadrangles so there is no need for specifying a list of cells. The number of cells on each dimension defines completely the topology.

Member Function Documentation

getInputCellIdI()

virtual size_t MeXTopologyIj::getInputCellIdI ( size_t  i, size_t  j  ) const

pure virtual

Returns cell indices (I/J/K) of the input cell containing the extracted cell with the given id.

This defines a mapping between extracted cells and input cells if the hasInputCellMapping() method returns true, otherwise these methods return UNDEFINED_ID.

Parameters

(i,j)

the index of the cell to check

Note

When dealing with a structured mesh as an input, the J/K indices may be UNDEFINED_ID. This is a temporary limitation. In that case, the I index is a flat index combining the 3 indices and must be unflatten using the input topology dimensions as follow:

size_t numCellsI = inputTopology.getNumCellsI();
size_t numCellsJ = inputTopology.getNumCellsJ();
size_t flatId = topology.getInputCellIdI(i,j);
size_t inputIdK = flatId / (numCellsI * numCellsJ);
size_t IJ = flatId % (numCellsI * numCellsJ);
size_t inputIdJ = IJ / numCellsI;
size_t inputIdI = IJ % numCellsI;

getInputCellIdJ()

virtual size_t MeXTopologyIj::getInputCellIdJ ( size_t  i, size_t  j  ) const

pure virtual

getInputCellIdK()

virtual size_t MeXTopologyIj::getInputCellIdK ( size_t  i, size_t  j  ) const

pure virtual

hasInputCellMapping()

virtual bool MeXTopologyIj::hasInputCellMapping ( ) const

pure virtual

Returns true if the input cell mapping is available.

If false, the getInputCellId() methods will return UNDEFINED_ID.
