Smooth boundary faces

[ParvGuptaSpCT]

Hello,
I'm trying to smooth the boundary faces of the mesh after cutting the mesh using contour.

I have used Smooth Boundary in Mesh Inspector, I'm trying to replicate the output in MeshLib (Python). Alternatively I have tried smoothRegionBoundary and smoothSelection with whole mesh as FaceBitSet but there were not change in the mesh. I also tried using positionVertsSmoothly which did smooth the boundary but it cut a substantial amount of mesh at the boundaries.

can you provide the settings or method used in the smooth the boundary of a mesh.

please find the mesh here

Thanks

Hello!

In this tool we use straightenBoundary function

MeshLib/source/MRMesh/MRMeshBoundary.h

Lines 10 to 15 in 9600de9

	/// adds triangles along the boundary to straighten it;
	/// \details new triangle is added only if
	/// 1) aspect ratio of the new triangle is at most maxTriAspectRatio,
	/// 2) dot product of its normal with neighbor triangles is at least minNeiNormalsDot.
	/// \ingroup MeshAlgorithmGroup
	MRMESH_API void straightenBoundary( Mesh & mesh, EdgeId bd, float minNeiNormalsDot, float maxTriAspectRatio, FaceBitSet* newFaces = nullptr );

bdEdges = mesh.topology.findHoleRepresentiveEdges()
for bd in bdEdges:
    mm.straightenBoundary( mesh, bd, 0.5, 10.0 );
