Description

Find the edge loop border around a set of triangles of a Mesh. This is computed via local walk and so does not create any full-mesh data structures. However current implementation may not be efficient for large triangle sets. Algorithm terminates if a non-manifold boundary is detected, and returns false if some triangles are unused.

static bool GetTriangleSetBoundaryLoop  
(  
    const FDynamicMesh3 & Mesh,  
    const TArray < int32 > & Tris,  
    FEdgeLoop & Loop  
)

static bool GetTriangleSetBoundaryLoop (     const FDynamicMesh3 & Mesh,     const TArray < int32 > & Tris,     FEdgeLoop & Loop )

true if a single well-formed loop was found, false if non-manifold or failure case encountered
