Function Documentation

◆ boulechknm()

int boulechknm	(	MMG5_pMesh	mesh,
		MMG5_int	start,
		int	ip,
		MMG5_int *	list
	)

Parameters

mesh	pointer to the mesh structure.
start	index of tetra to start to compute the ball.
ip	index of point in tetra start for which we want to compute the ball.
list	pointer to the computed ball of point.

Returns: size of list if success, -size if overflow, 0 if cfg is non-manifold.

Find all triangles sharing ip, \(list[0] = start\) . Do not stop when crossing ridge. Check whether resulting configuration is manifold.

◆ bouletrid()

int bouletrid	(	MMG5_pMesh	mesh,
		MMG5_int	start,
		MMG5_int	ip,
		int *	il1,
		MMG5_int *	l1,
		int *	il2,
		MMG5_int *	l2,
		MMG5_int *	ip0,
		MMG5_int *	ip1
	)

Parameters

mesh	pointer to the mesh structure.
start	index of the starting triangle.
ip	index of the looked ridge point.
il1	pointer to the first ball size.
l1	pointer to the first computed ball (associated to n1's side).
il2	pointer to the second ball size.
l2	pointer to the second computed ball (associated to n2's side).
global	ip0 index of the first extremity of the ridge.
global	ip1 index of the second extremity of the ridge.

Returns: 0 if fail, 1 otherwise.

Computation of the two balls of a ridge point: the list l1 is associated to normal n1's side. ip0 and ip1 are the indices of the 2 ending point of the ridge. Both lists are returned enumerated in direct order.
