Constructor & Destructor Documentation

template<typename PolyMeshType >

vcg::tri::PolychordCollapse< PolyMeshType >::LinkConditions::LinkConditions

(

[inline]

LinkCondition constructor.

Parameters:

size	The number of vertices of the mesh.

Member Function Documentation

template<typename PolyMeshType >

bool vcg::tri::PolychordCollapse< PolyMeshType >::LinkConditions::CheckLinkConditions	(	const PolyMeshType &	mesh,
		const vcg::face::Pos< FaceType > &	startPos
	)		[inline]

CheckLinkConditions checks if collapsing the polychord starting from startPos satisfies the link conditions.

Warning:

The polychord starts from startPos and ends to itself (if it's a loop) or to a border. In the latter case, call this method starting from the opposite border of the strip of quads.

Parameters:

mesh	The mesh for getting the vertex index.
startPos	The starting position of the polychord.

Returns:

true if satisfied, false otherwise.

		const vcg::face::Pos< FaceType > &	startPos,
		std::vector< LCEdge > &	lcEdges
	)		[inline, private]

LC_computeStars computes the stars of edges and vertices of the polychord from the starting pos either to itself (if it's a loop) or to the border edge.

Parameters:

mesh	The mesh for getting the vertex index.
startPos	Starting position.
lcEdges	Vector of edge stars.

compute the star of all the vertices and edges seen from the polychord

void vcg::tri::PolychordCollapse< PolyMeshType >::LinkConditions::LC_SimulateEdgeCollapse	(	std::vector< LCEdge > &	lcEdges,
		const LCEdgeIndex	edgeInd
	)		[inline, private]

LC_SimulateEdgeCollapse simulates an edge collapse by updating the stars involved.

Parameters:

lcEdges	The vector of edges.
edgeInd	The in dex of the edge to collapse.

v2 merges into v1:

update the star of the edges which include v1 and v2 in their star
