Adding and removing noise Example

• Python

  Note

  Python API version 3 and later

  from meshlib import mrmeshpy as mm
   
  # Load mesh
  mesh = mm.loadMesh("mesh.stl")
   
  # Create parameters for adding noise
  nSettings = mm.NoiseSettings()
  nSettings.sigma = mesh.computeBoundingBox().diagonal()*0.0001
   
  # Add noise to mesh
  mm.addNoise(mesh.points,mesh.topology.getValidVerts(),nSettings)
   
  # Save noised mesh
  mm.saveMesh(mesh,"noised_mesh.stl")
   
  # Denoise mesh with sharpening for sharp edges
  # see the article "Mesh Denoising via a Novel Mumford-Shah Framework"
  mm.meshDenoiseViaNormals( mesh )
   
  # Save denoised mesh
  mm.saveMesh(mesh,"denoised_mesh.stl")
