Detailed Description

The WEMConnectedComponent namespace.

Function Documentation

◆ collectComponent() [1/2]

MLWEM_EXPORT void ml::WEMConnectedComponent::collectComponent	(	WEMPatch *	wemPatch,
		WEMNode *	node,
		WEMNodeVector &	cNodes,
		bool	unvisitedValue = `false`
	)

Collects a connected component of a wemPatch, starting with a node.

The resulting nodes are collected in the cNodes vector. The unvisitedValue determines, which primitives (nodes) are marked as yet visited or not. The 'visited' status is encoded in the 'isTraversed' flag of the nodes.

◆ collectComponent() [2/2]

MLWEM_EXPORT bool ml::WEMConnectedComponent::collectComponent	(	WEMPatch *	wemPatch,
		WEMNodeVector &	cNodes,
		bool	unvisitedValue = `false`
	)

Collects a connected component and stores the nodes in the given WEMNodeVector and returns whether a connected component was collected.

◆ collectComponentBoundary()

MLWEM_EXPORT void ml::WEMConnectedComponent::collectComponentBoundary	(	WEMPatch *	wemPatch,
		WEMNode *	node,
		WEMNodeVector &	cNodes,
		bool	unvisitedValue = `false`
	)

Same as 'collectComponent', but now the starting node should be on a boundary.

Only connected nodes which are on a boundary are collected in the cNodes vector.

◆ collectComponentEuclideanDistance()

MLWEM_EXPORT void ml::WEMConnectedComponent::collectComponentEuclideanDistance	(	WEMPatch *	wemPatch,
		WEMNode *	node,
		WEMNodeVector &	cNodes,
		double	maxDistance,
		bool	unvisitedValue = `false`
	)

Same as 'collectComponent', but with an additional range parameter maxDistance.

The collection of a connected component stops if the nodes traversal state is not 'unvisited' OR if its euclidean distance to the starting node exceeds the maxDistance value.

◆ collectComponentFaceCut()

MLWEM_EXPORT bool ml::WEMConnectedComponent::collectComponentFaceCut	(	WEMNode *	node,
		std::vector< WEMNode * > &	cNodes,
		std::vector< WEMFace * > &	cFaces,
		WEMVector< WEMFaceCut > **	faceCuts,
		unsigned int	outerFlag,
		unsigned int	intersectingFlag,
		bool	visitedValue = `true`
	)

Collects a connected component of a WEM, starting with a node.

The resulting nodes are collected in the cNodes and cFaces vectors. The visitedValue determines, which primitives (nodes) are marked as yet visited or not. The 'visited' status is encoded in the 'isTraversed' flag of the nodes. On return the common bool value for the given outerFlag is returned Additional checks are done on intersectingFlag

◆ collectComponentPrimitiveValueList()

MLWEM_EXPORT void ml::WEMConnectedComponent::collectComponentPrimitiveValueList	(	WEMPatch *	wemPatch,
		WEMNode *	node,
		WEMNodeVector &	cNodes,
		WEMFaceVector &	cFaces,
		WEMFaceVector &	iFaces,
		WEMPrimitiveValueList *	valueList,
		double	valueRange,
		unsigned int	connectedFlag,
		bool	unvisitedValue = `false`
	)

Collects a connected component of a WEMPatch, starting with a node.

The resulting nodes are collected in the cNodes and cFaces vectors. The unvisitedValue determines, which primitives (nodes) are marked as yet visited or not. The 'visited' status is encoded in the 'isTraversed' flag of the nodes. Additional checks are done on connectedFlag.

◆ collectComponentPseudoGeodesicDistance()

MLWEM_EXPORT void ml::WEMConnectedComponent::collectComponentPseudoGeodesicDistance	(	WEMPatch *	wemPatch,
		WEMNode *	node,
		WEMNodeVector &	cNodes,
		double	maxDistance,
		bool	unvisitedValue = `false`
	)

Collects all connected (node) components up to a given maximum distance which is measured as the sum of the lengths of the connecting edges.

This is a geodesic distance with an error due to the edge directions.

◆ getPathLengthBetweenNodes()

MLWEM_EXPORT double ml::WEMConnectedComponent::getPathLengthBetweenNodes	(	WEMPatch *	wemPatch,
		const std::vector< unsigned int > &	nodeIndicesPath
	)

Returns the sum of the lengths of the edges between the nodes given as indices in a given WEMPatch.
