Name	Type	Remarks	Include Path
MElements	TArray< TVec2< int32 > >	We use TVector rather than FEdge to represent connectivity because sizeof(TVec2) < sizeof(FEdge).	Chaos/SegmentMesh.h
MPointToEdgeMap	TMap< int32, TArray< int32 > >	Members are mutable so they can be generated on demand by const API.	Chaos/SegmentMesh.h
MPointToNeighborsMap	TMap< int32, TSet< int32 > >		Chaos/SegmentMesh.h

TArray< FReal > GetEdgeLengths ( const TParticles< FReal, 3 >& InParticles, const bool lengthSquared ) const	@ret Lengths (or lengths squared) of all edges.	Chaos/SegmentMesh.h
const TArray< TVec2< int32 > > & GetElements()		Chaos/SegmentMesh.h
const TSet< int32 > * GetNeighbors ( const int32 index ) const	@ret The set of neighbor nodes, or nullptr if `index_ is not found.	Chaos/SegmentMesh.h
int32 GetNumElements()		Chaos/SegmentMesh.h
const TMap< int32, TArray< int32 > > & GetPointToEdges()	@ret A map of each point index to the list of connected edges.	Chaos/SegmentMesh.h
