static void vcg::tri::UpdateTopology< UpdateMeshType >::AllocateEdge ( MeshType & m )

inlinestatic

Initialize the edge vector all the edges that can be inferred from current face vector, setting up all the current adjacency relations.

template<class UpdateMeshType >

static void vcg::tri::UpdateTopology< UpdateMeshType >::ClearFaceFace ( MeshType & m )

inlinestatic

Clear the Face-Face topological relation setting each involved pointer to null. useful when you passed a mesh with ff adjacency to an algorithm that does not use it and could have messed it.

static void vcg::tri::UpdateTopology< UpdateMeshType >::ClearTetraTetra ( MeshType & m )

inlinestatic

Clear the tetra-tetra topological relation, setting each involved pointer to null. useful when you passed a mesh with tt adjacency to an algorithm that does not use it and chould have messed it.

static void vcg::tri::UpdateTopology< UpdateMeshType >::FaceFace ( MeshType & m )

inlinestatic

Update the Face-Face topological relation by allowing to retrieve for each face what other faces shares their edges.

template<class UpdateMeshType >

static void vcg::tri::UpdateTopology< UpdateMeshType >::FaceFaceFromTexCoord ( MeshType & m )

inlinestatic

Update the Face-Face topological relation so that it reflects the per-wedge texture connectivity.

Using this function two faces are adjacent along the FF relation IFF the two faces have matching texture coords along the involved edge. In other words F1->FFp(i) == F2 iff F1 and F2 have the same tex coords along edge i

static void vcg::tri::UpdateTopology< UpdateMeshType >::FillEdgeVector	(	MeshType &	m,
		std::vector< PEdge > &	edgeVec,
		bool	includeFauxEdge = `true`
	)

inlinestatic

Fill a vector with all the edges of the mesh. each edge is stored in the vector the number of times that it appears in the mesh, with the referring face. optionally it can skip the faux edges (to retrieve only the real edges of a triangulated polygonal mesh)

static void vcg::tri::UpdateTopology< UpdateMeshType >::TestFaceFace ( MeshType & m )

template<class UpdateMeshType >

static void vcg::tri::UpdateTopology< UpdateMeshType >::VertexFace ( MeshType & m )

inlinestatic

Update the Vertex-Face topological relation.

The function allows to retrieve for each vertex the list of faces sharing this vertex. After this call all the VF component are initialized. Isolated vertices have a null list of faces.
