void CHomology::computeIncidence	(	int	ADim,
		bool	AComputeNextCells = `false`
	)

protected

Compute the incidence matrix for cells of dimension ADim. The incidence matrix FMatrix[ADim] is updated.

Parameters

ADim	the dimension of the incidence matrix (0 for vertex-edge, 1 for edge-face, 2 for face-volume)
AComputeNextCells	true to compute also the ADim+1 cells (ADim >= 0) && (ADim < 3)

Definition at line 146 of file compute-homology.cc.

int CHomology::computeIncidenceNumber	(	CDart *	ADart,
		int	ADim,
		CDart *	ADart2,
		int	AIndex
	)

protected

Compute the incidence number of cell c=(ADart,ADim), relatively to the cell c2=(ADart2,ADim+1). Incidence number is the number of times c is incident to c2. This number is signed depending if the two cells have the same orientation (+) or not (-).

Parameters

ADart	A dart of the cell c
ADim	The dimension of the cell c
ADart	A adart of the cell c2
AIndex	A direct info which number each ADim cell (+i or -i).

Returns: The signed incidence number of c in c2

(ADim >= 0) && (ADim < 3)
