Member Function Documentation

template<class MeshType, typename Scalar = double>

template<typename ScalarT >

static ScalarT vcg::tri::Harmonic< MeshType, Scalar >::ComputeAngle	(	const VertexType *	a,
		const VertexType *	b,
		const VertexType *	c
	)		[inline, static]

Definition at line 256 of file harmonic.h.

template<class MeshType, typename Scalar = double>

template<typename ACCESSOR >

static bool vcg::tri::Harmonic< MeshType, Scalar >::ComputeScalarField	(	MeshType &	m,
		const ConstraintVec &	constraints,
		ACCESSOR	field,
		bool	biharmonic = false
	)		[inline, static]

ComputeScalarField Generates a scalar harmonic field over the mesh. For more details see:
Kai Xua, Hao Zhang, Daniel Cohen-Or, Yueshan Xionga,'Dynamic Harmonic Fields for Surface Processing'. Computers & Graphics, 2009.

Parameters:

m	the mesh
constraints	the Dirichlet boundary conditions in the form of vector of pairs <vertex pointer, value>.
field	the accessor to use to write the computed per-vertex values (must have the [ ] operator).

Returns:

true if the algorithm succeeds, false otherwise.

Note:

the algorithm has unexpected behavior if the mesh contains unreferenced vertices.

template<class MeshType, typename Scalar = double>

template<typename ScalarT >

static ScalarT vcg::tri::Harmonic< MeshType, Scalar >::CotangentWeight	(	const FaceType &	f,
		int	edge
	)		[inline, static]

ComputeWeight computes the cotangent weighting for an edge.

Parameters:

f	the face
edge	the edge of the provided face for which we compute the weight

Returns:

the computed weight

Note:

the mesh must have the face-face topology updated

Definition at line 214 of file harmonic.h.

template<class MeshType, typename Scalar = double>

template<typename ScalarT >

static WeightInfo vcg::tri::Harmonic< MeshType, Scalar >::CotangentWeightIfNotVisited	(	const FaceType &	f,
		int	edge,
		ScalarT &	weight
	)		[inline, static]

CotangentWeightIfNotVisited computes the cotangent weighting for an edge (if it has not be done yet). This must be ensured setting the visited flag on the face once all edge weights have been computed.

Parameters:

f	the face
edge	the edge of the provided face for which we compute the weight
weight	the computed weight (output)

Returns:

Success if everything is fine, EdgeAlreadyVisited if the weight for the considered edge has been already computed.

Note:

the mesh must have the face-face topology updated
