Unable to get the similar result in inflate method

[ParvGuptaSpCT]

Hello @Grantim!!

I was trying to use inflate method and I'm unable to reproduce the same result as i Mesh Inspector Application.

Here's the steps I followed:

1. Fill the hole with fillHoleNicely
   
2. Decimate the filled mesh
   
3. inflate the mesh with pressure = 10
   

here's the code snippet

params = mm.FillHoleNicelySettings()
params.maxEdgeSplits = 1000000 
params.maxEdgeLen = toothMesh.averageEdgeLength()
params.smoothCurvature = True 

holes = mesh.topology.findHoleRepresentiveEdges()

maxAreaHole = mm.EdgeId()
maxHoleAreaSq = 0

# find max area hole
for e in holes:
    areaSq = mesh.holeDirArea(e).lengthSq()
    if (areaSq > maxHoleAreaSq):
        maxHoleAreaSq = areaSq
        maxAreaHole = e

for e in holes:
   newFaces = mm.fillHoleNicely(mesh, e, params)
   if (e==maxAreaHole):
      dSetting = mm.DecimateSettings()
      dSetting.region = newFaces
      dSetting.touchNearBdEdges = True
      dSetting.packMesh = True
      dSetting.optimizeVertexPos = True
      dSetting.maxError = mesh.computeBoundingBox().diagonal()*1e-3
                
      mm.decimateMesh(mesh, dSetting)
      mm.saveMesh(mesh, f'tmp/decimate{toothNumber}.stl')

      newVerts = mm.getInnerVerts(mesh.topology,newFaces)
      infParams = mm.InflateSettings()
      infParams.preSmooth = False
      infParams.pressure = 15
      mm.inflate(mesh, newVerts, infParams)

Output from the code:

Here's the mesh i'm using: mesh

Hello!

Some of the settings in MeshInspctor might be different then defaults in MeshLib, this settings are closer to MeshInspector:

from meshlib import mrmeshpy as mm

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

params = mm.FillHoleNicelySettings()
params.maxEdgeSplits = 20000 
params.maxEdgeLen = 0.24204#mesh.averageEdgeLength()
params.triangulateParams.metric = mm.getUniversalMetric(mesh)
params.triangulateOnly = False
params.triangulateParams.multipleEdgesResolveMode = params.triangulateParams.MultipleEdgesResolveMode.Strong
params.smoothCurvature = True
params.edgeWeights = mm.EdgeWeights.CotanWithAreaEqWeight

holes = mesh.topology.findHoleRepresentiveEdges()

maxAreaHole = mm.EdgeId()
maxHoleAreaSq = 0

# find max area hole
for e in holes:
    areaSq = mesh.holeDirArea(e).lengthSq()
    if (areaSq > maxHoleAreaSq):
        maxHoleAreaSq = areaSq
        maxAreaHole = e

for e in holes:
   newFaces = mm.fillHoleNicely(mesh, e, params)
   if (e==maxAreaHole):
      dSetting = mm.DecimateSettings()
      dSetting.region = newFaces
      dSetting.touchNearBdEdges = True
      dSetting.packMesh = True
      dSetting.optimizeVertexPos = True
      dSetting.stabilizer = 0.000001
      dSetting.maxEdgeLen = 15.5
      dSetting.criticalTriAspectRatio = 10000
      dSetting.subdivideParts = 1
      dSetting.maxTriangleAspectRatio = 20
      dSetting.angleWeightedDistToPlane = False
      dSetting.maxError = 0.0155#mesh.computeBoundingBox().diagonal()*1e-3
      mm.decimateMesh(mesh, dSetting)

      newVerts = mm.getInnerVerts(mesh.topology,newFaces)
      mm.positionVertsSmoothlySharpBd(mesh,newVerts)
      infParams = mm.InflateSettings()
      infParams.preSmooth = False
      infParams.pressure = 15
      mm.inflate(mesh, newVerts, infParams)

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

hello @Grantim!!
The output is still little different from the MeshInspector UI but it is inside the acceptable error margin.
Thanks for the help!!
