Function Documentation

boulechknm()

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

Parameters

mesh	pointer toward 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 toward the computed ball of point.

Find all triangles sharing ip, . Do not stop when crossing ridge. Check whether resulting configuration is manifold.

Here is the caller graph for this function:

boulep()

int boulep	(	MMG5_pMesh	mesh,
		int	start,
		int	ip,
		int *	list
	)

Here is the caller graph for this function:

boulet()

int boulet	(	MMG5_pMesh	mesh,
		int	start,
		int	ip,
		int *	list
	)

Parameters

mesh	pointer toward the mesh structure.
start	index of triangle to start.
ip	index of point for wich we compute the ball.
list	pointer toward the computed ball of ip.

Returns

the size of the computed ball or 0 if fail.

Find all triangles sharing ip, start do not stop when crossing ridge.

Here is the caller graph for this function:

bouletrid()

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

Parameters

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