Syntax
template<typename IntrinsicMeshType>
struct TEdgeCorrespondence
Remarks
TEdgeCorrespondence allows intrinsic edges to be traced across the underlying surface mesh. When computing a large number intrinsic edge traces, this is to be preferred over the TraceEdge() intrinsic mesh methods because it avoids redundant computations. But when tracing a small number of intrinsic edges the large up-front cost of computing information the entire mesh will make use of this class sub-optimal.
During construction a list of surface mesh edges crossed by each intrinsic edge is stored. The Trace operation for an intrinsic edge uses this information to unfold the crossed surface triangles into a 2d triangle strip upon which the actual trace takes place.
This is only for use with intrinsic mesh implementations that support 'normal coordinates' when doing flips/splits and pokes. such as the FIntrinsicMesh and FIntrinsicEdgeFlipMesh.
