How to use reposition with smooth boundary in Python

[ParvGuptaSpCT]

Hello Devs!

I'm trying to replicate reposition feature in MeshInspector after filling hole with smooth curvature, but unable to reproduce the same result in code. for reference I'm adding the steps below;

1. fil hole with smooth curvatrures

2. decimate mesh with default tolerance

3. reposition the new faces with smooth boundaries

Can you help me with the which method and parameters will help me reproduce the same result.
you can find the mesh here

Thanks!!

Hello!

The script should look somehow like this:
(you can tune the parameters to slightly change the result)

from meshlib import mrmeshpy as mm

mesh = mm.loadMesh(__file__+"/../clean_mesh.stl")

# fill hole
fhnSettings = mm.FillHoleNicelySettings()
fhnSettings.smoothCurvature = True
fhnSettings.triangulateOnly = False
fhnSettings.triangulateParams.metric = mm.getUniversalMetric(mesh)
fhnSettings.maxEdgeLen = mesh.averageEdgeLength()
fhnSettings.maxEdgeSplits = 1000000 # just large number not to stop too early
fhnSettings.naturalSmooth = False
newFaces = mm.fillHoleNicely(mesh,mesh.topology.findHoleRepresentiveEdges()[0],fhnSettings)

# decimate
dSettings = mm.DecimateSettings()
dSettings.maxError = 0.001 * (mesh.computeBoundingBox().diagonal() / 3.0)
dSettings.maxDeletedFaces = 1000000 # just large number not to stop too early
dSettings.maxDeletedVertices = 1000000 # just large number not to stop too early
dSettings.region = newFaces
mm.decimateMesh(mesh,dSettings)

# reposition
incidentVerts = mm.getIncidentVerts(mesh.topology,newFaces)
mm.positionVertsSmoothly(mesh,incidentVerts,mm.EdgeWeights.Cotan,mm.VertexMass.NeiArea)

mm.saveMesh(mesh,__file__+"/../res.stl")
