Hello!

One can use it like this:

from meshlib import mrmeshpy as mm

# load mesh
mesh = mm.loadMesh("path/to/mesh.stl")
# setup selection
selection = mm.VertBitSet()
selection.resize( mesh.topology.getValidVerts().size() )
selection.set( mm.VertId(0), True )
# expand selection
mm.expand(mesh.topology, selection, 5 )

# reposition
# optionally preposition in case of possible degenerated input, to get better results
#mm.positionVertsSmoothlySharpBd( mesh, selection )
mm.positionVertsSmoothly( mesh, selection, mm.LaplacianEdgeWeightsParam.CotanWithAreaEqWeight )

# save mesh
mm.saveMesh( mesh, "path/to/repositioned_mesh.stl" )
