centroid coordinates for holes

[DMBabich]

Hello!
How I can get and change coordinates for centroid in fillHoleTrivially() ?

Documentation says: "Fills given hole represented by one of its edges (having no valid left face)
by creating one new vertex in the centroid of boundary vertices and connecting new vertex with all boundary vertices"

also: how I can force use fillHoleTrivially() if I have "true" holes?

Just I mean:
1 - I have broken model (untitled.stl) (upper brick)
2 - I try fix holes by:

import meshlib.mrmeshpy as mrmeshpy

# Load mesh
mesh = mrmeshpy.loadMesh("untitled.stl")

# Find single edge for each hole in mesh
hole_edges = mesh.topology.findHoleRepresentiveEdges()

for e in hole_edges:
    #  Setup filling parameters
    params = mrmeshpy.FillHoleParams()
    params.metric = mrmeshpy.getUniversalMetric(mesh)
    #  Fill hole represented by `e`
    mrmeshpy.fillHole(mesh, e, params)

# Save result
mrmeshpy.saveMesh(mesh, "fixedMesh.stl")

and I get fixed model (fixedMesh.stl) (middle brick)

But I want use fillHoleTrivially() and force changes coordinates for holes centroid to fill holes (cool.stl) (lower brick)

How I can do it?
Please help ♥

for example:
every holes centroid Z-coordinate -= 5
(subtract 5 for each hole z-coord)

Hello!

In older versions of meshlib python you could not call fillHoleTrivially manually, but after our latest release it is possible:

from meshlib import mrmeshpy

# Load mesh
mesh = mrmeshpy.loadMesh("untitled.stl")

# Find single edge for each hole in mesh
hole_edges = mesh.topology.findHoleRepresentiveEdges()

for e in hole_edges:
    #  Setup filling parameters
    params = mrmeshpy.FillHoleParams()
    params.metric = mrmeshpy.getUniversalMetric(mesh)
    #  Fill hole represented by `e`
    centroidV = mrmeshpy.fillHoleTrivially(mesh, e)
    mesh.points.vec[centroidV.get()].z -= 5

mesh.invalidateCaches() # need to invalidate caches after manually changing coordinates
# Save result
mrmeshpy.saveMesh(mesh, "fixedMesh.stl")

This script should work for you:
Make sure to get new version of meshlib python module like this

pip install meshlib==3.0.0.40

note that version should be set explicitly because new python modules have some signature differences from older version

Thank you
It's great :)
