Parameters:

removeIsolatedPoints

if true isolated vertices are also removed

void sofa::component::topology::ManifoldEdgeSetTopologyModifier::removeEdges	(	sofa::helper::vector< unsigned int > &	edges,
		const bool	removeIsolatedPoints = `true`
	)			`[virtual]`

Remove a set of edges.

Parameters:

edges

an array of edge indices to be removed (note that the array is not const since it needs to be sorted)

add the topological changes in the queue

void sofa::component::topology::ManifoldEdgeSetTopologyModifier::removeEdgesProcess	(	const sofa::helper::vector< unsigned int > &	indices,
		const bool	removeIsolatedItems = `false`
	)			`[virtual]`

Effectively Remove a subset of edges.

Eventually remove isolated vertices

Elements corresponding to these edges are removed form the mechanical object's state vectors.

Important : some structures might need to be warned BEFORE the edges are actually deleted, so always use method removeEdgesWarning before calling removeEdgesProcess.

See also:: removeEdgesWarning

Important : parameter indices is not const because it is actually sorted from the highest index to the lowest one.

Parameters:

removeIsolatedItems

if true isolated vertices are also removed
