Syntax

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

Remarks

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.

Returns

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

Parameters

Parameter	Description
Loop	output loop will be stored here. This value is garbage if false is returned.
