Function Documentation

MMG2D_bouleendp()

int MMG2D_bouleendp	(	MMG5_pMesh	mesh,
		MMG5_int	start,
		int8_t	ip,
		MMG5_int *	ip1,
		MMG5_int *	ip2,
		MMG5_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.

Returns

1 if success, 0 if fail.

Find the two endpoints of the boundary curves joining ip, fill ip1 and ip2 with their indices and list neighbouring triangles

MMG2D_boulen()

int MMG2D_boulen	(	MMG5_pMesh	mesh,
		MMG5_int	start,
		int8_t	ip,
		MMG5_int *	pleft,
		MMG5_int *	pright,
		double *	nn
	)

Parameters

mesh	pointer toward the mesh
start	index of the first tria
ip	local index of the point on which we work in tria start
pleft	index of the left point of ip along the geom edge (local index of the point inside a triangle)
pright	index of the right point of ip along the geom edge (local index of the point inside a triangle)
nn	computed normal at ip

Returns

0 if fail, 1 if success

Travel the ball of point ip in triangle start, which is assumed to lie either on the external or on an internal boundary of the mesh, and return the normal vector convention: the normal vector is oriented from the half ball it starts with towards its exterior return pright = 3*kk+ii, where kk = last triangle in the first travel, and ii = local index of ip in kk pleft = 3*kk+ii, where kk = last triangle in the second travel, and ii = local index of ip in kk.
