Class EdgeLoop
Sequential set of vertices/edges in a mesh, that form a closed loop.
If all you have are the vertices, use EdgeLoop.VertexLoopToEdgeLoop() to construct an EdgeLoop

Returns
CorrectOrientation()
if this is a border edge-loop, we can check that it is oriented correctly, and
if not, reverse it.
Returns true if we reversed orientation.
Declaration
public bool CorrectOrientation()
Returns
CountWithinTolerance(Vector3d, Double, out Int32)
Declaration
public int CountWithinTolerance(Vector3d v, double tol, out int last_in_tol)
Parameters
Returns
FindNearestVertex(Vector3d)
find index of vertices of loop that is closest to point v
Declaration
public int FindNearestVertex(Vector3d v)
Parameters
Returns
FindVertexIndex(Int32)
find index of vertex vID in Vertices list, or -1 if not found

Returns
FromEdges(DMesh3, IList<Int32>)
construct EdgeLoop from a list of edges of mesh
Declaration
public static EdgeLoop FromEdges(DMesh3 mesh, IList<int> edges)
Parameters
Returns
FromVertices(DMesh3, IList<Int32>)
construct EdgeLoop from a list of vertices of mesh
Declaration
public static EdgeLoop FromVertices(DMesh3 mesh, IList<int> vertices)
Parameters
Returns
FromVertices(DMesh3, IList<Int32>, Boolean)
construct EdgeLoop from a list of vertices of mesh
if loop is a boundary edge, we can correct orientation if requested

Returns
GetVertexSpan(Int32, Int32, Int32[], Boolean)
stores vertices [starti, starti+1, ... starti+count-1] in span, and returns span, or null if invalid range
Declaration
public int[] GetVertexSpan(int starti, int count, int[] span, bool reverse = false)
Parameters
Returns
IsBoundaryLoop(DMesh3)
Check if all edges of this loop are boundary edges.
If testMesh != null, will check that mesh instead of internal Mesh
