MMG5_boulec()

int MMG5_boulec	(	MMG5_pMesh	mesh,
		MMG5_int *	adjt,
		MMG5_int	start,
		int	ip,
		double *	tt
	)

Parameters

mesh	pointer to the mesh structure.
adjt	pointer to the table of triangle adjacency.
start	index of triangle where we start to work.
ip	index of vertex where the tangent is computed.
tt	pointer to the computed tangent.

Returns

0 if fail, 1 otherwise.

Compute the tangent to the curve at point ip.

Parameters

mesh	pointer to the mesh structure.

listref	pointer to the corresponding edge references
ng	pointer to the number of ridges.
nr	pointer to the number of reference edges.
lmax	maxmum size for the ball of the point ip.

Returns

	)

Parameters

mesh	pointer to the mesh structure.
start	index of triangle to start.
ip	index of point for wich we compute the ball.
list	pointer to the computed ball of ip.
s	1 if called from mmgs, 0 if called from mmg2d.
opn	0 for a closed ball, 1 for an open ball.

Returns

the size of the computed ball or 0 if fail.

Find all triangles sharing ip, \(list[0] =\) start do not stop when crossing ridge.
