Detailed Description

template<class MeshType>
class vcg::tri::UpdateHalfEdges< MeshType >

This class is used to build edge based data structure from indexed data structure and viceversa.

Member Function Documentation

AddHEdge()

template<class MeshType >

static void vcg::tri::UpdateHalfEdges< MeshType >::AddHEdge ( MeshType &  m, HEdgeType *  e0, HEdgeType *  e1  )

inlinestatic

Adds an edge between the sources of e0 and e1 and set all the topology relations. If the edges store the pointers to the faces then a new face is created. <— e1 -— X <---—e1_HEPp— ^ || ei0 || ei1 || v -—e0_HEPp-> X --— e0 ---—>

CheckConsistency()

template<class MeshType >

static bool vcg::tri::UpdateHalfEdges< MeshType >::CheckConsistency ( MeshType &  m )

inlinestatic

Checks that half edges and face relation are consistent

CheckConsistency_FHp()

template<class MeshType >

static bool vcg::tri::UpdateHalfEdges< MeshType >::CheckConsistency_FHp ( MeshType &  m )

inlinestatic

Checks pointers FHEp() are valid

FromIndexed()

template<class MeshType >

static void vcg::tri::UpdateHalfEdges< MeshType >::FromIndexed ( MeshType &  m )

inlinestatic

build a half-edge data structure from an indexed data structure. Note that the half-edges are allocated here for the first time. If you have a mesh where there are already edges, they will be removed and the data lost, so do not use this function to just "update" the topology of half edges.

RemoveHEdge()

template<class MeshType >

static void vcg::tri::UpdateHalfEdges< MeshType >::RemoveHEdge ( MeshType &  m, HEdgeType *  e  )

inlinestatic

Detach the topology relations of a given edge <— e->HENPp -X — <------—eO_HEPp— ^ || e || e->HEOp() || v -—e_HEPp--> X --— e->HEOp->HENPp() ---—>
