MMG5_boulec()

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

Parameters

mesh	pointer toward the mesh structure.
adjt	pointer toward 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 toward the computed tangent.

Returns

0 if fail, 1 otherwise.

Compute the tangent to the curve at point ip.

	)

Parameters

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

	)

Parameters

mesh	pointer toward the mesh structure.

ip	index of vertex on which we work.
list	pointer toward the computed list of GEO vertices incident to ip.
listref	pointer toward the corresponding edge references
ng	pointer toward the number of ridges.
nr	pointer toward the number of reference edges.
lmax	maxmum size for the ball of the point ip.

Returns

The number of edges incident to the vertex ip.

	)

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.
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, start do not stop when crossing ridge.
