Function Documentation

template<class EdgeType >

bool vcg::edge::IsEdgeBorder	(	EdgeType const &	e,
		const int	j
	)		[inline]

Return a boolean that indicate if the j-th edge of the face is a border.

Parameters:

j	Index of the edge

Returns:

true if j is an edge of border, false otherwise

bool vcg::edge::IsEdgeManifoldFF	(	EdgeType const &	e,
		const int	j
	)		[inline]

template<class EdgeType >

void vcg::edge::VEAppend	(	EdgeType *	e,
		int	z
	)

Append an edge in the VE list of vertex e->V(z)

template<class EdgeType >

int vcg::edge::VEDegree

(

const typename EdgeType::VertexType *

vp

)

Returns the number of incident edges over a vertex vp; Using the VE adjacency.

It just follows the chain of incident edges of the VE adjacency.

template<class EdgeType >

void vcg::edge::VEDetach

(

EdgeType &

e

)

Completely detach an edge from the VE adjacency. Useful before deleting it.

Definition at line 85 of file simplex/edge/topology.h.

template<class EdgeType >

void vcg::edge::VEDetach	(	EdgeType &	e,
		int	z
	)

It detaches the given edge e from the VE adjacency on the vertex z It is used for careful hand stictching of topologies.

Definition at line 94 of file simplex/edge/topology.h.

template<class MeshType >

void vcg::edge::VEEdgeCollapse	(	MeshType &	poly,
		typename MeshType::EdgeType *	e0,
		const int	z
	)

Perform a simple edge collapse using VE adjacency

It collapses the two edges incidnent on the indicated vertex so that the passed edge survives, the indicated vertex is deleted, and the edge ajacent to e0 along z is deleted too. It assumes that the edge mesh is 1-Manifold. If the indicated vertex <vd> is boundary or non manifold the function do nothing.

v0 vd v1 ---O-------O-------O--- z0 e0 z e1 z1

v0 v1 ---O---------------O--- e0
