Definition at line 265 of file simplex/face/topology.h.

template<class FaceType >

void vcg::face::Attach	(	FaceType *&	f,
		int	z1,
		FaceType *&	f2,
		int	z2
	)			[inline]

This function attach the face (via the edge z1) to another face (via the edge z2). It's possible to use it also in non-two manifold situation. The function cannot be applicated if the adjacencies among faces aren't define.

Parameters:

	z1	Index of the edge
	f2	Pointer to the face
	z2	The edge of the face f2

template<class FaceType >

bool vcg::face::FFCorrectness	(	FaceType &	f,
		const int	e
	)			[inline]

This function check the FF topology correctness for an edge of a face. It's possible to use it also in non-two manifold situation. The function cannot be applicated if the adjacencies among faces aren't defined.

Parameters:

	f	the face to be checked
	e	Index of the edge to be checked

Definition at line 117 of file simplex/face/topology.h.

template<class FaceType >

void vcg::face::FFDetach	(	FaceType &	f,
		const int	e
	)			[inline]

This function detach the face from the adjacent face via the edge e. It's possible to use it also in non-two manifold situation. The function cannot be applicated if the adjacencies among faces aren't defined.

Parameters:

	f	the face to be detached
	e	Index of the edge to be detached

Definition at line 188 of file simplex/face/topology.h.

template<class FaceType >

void vcg::face::FFDetachManifold	(	FaceType &	f,
		const int	e
	)			[inline]

This function detach the face from the adjacent face via the edge e. It's possible to use this function it ONLY in non-two manifold situation. The function cannot be applicated if the adjacencies among faces aren't defined.

Parameters:

	f	the face to be detached
	e	Index of the edge to be detached

Definition at line 158 of file simplex/face/topology.h.

template<class FaceType >

static void vcg::face::FlipEdge	(	FaceType &	f,
		const int	z
	)			[inline, static]

Flip the z-th edge of the face f. Check for topological correctness first using CheckFlipFace().

Parameters:

	f	pointer to the face
	z	the edge index

Note: For edge flip we intend the swap of the diagonal of the rectangle formed by the face f and the face adjacent to the specified edge.
