Viewer Example

Example of using Viewer

• Python

  Note

  Python API version 3 and later

  import os
  from meshlib import mrmeshpy as mm
  from meshlib import mrviewerpy as mv
   
  # Load mesh
  mesh = mm.loadMesh("mesh.stl")
   
  # Setup parameters
  params = mm.OffsetParameters()
  params.voxelSize = mesh.computeBoundingBox().diagonal() * 5e-3  # offset grid precision (algorithm is voxel based)
  if mm.findRightBoundary(mesh.topology).empty():
      params.signDetectionMode = mm.SignDetectionMode.HoleWindingRule  # use if you have holes in mesh
   
  # Make offset mesh
  offset = mesh.computeBoundingBox().diagonal() * 0.05
  result_mesh = mm.offsetMesh(mesh, offset, params)
   
   
  mv.launch() # a window will be opened
  mv.addMeshToScene(mesh, "Mesh 1") # show initial mesh
  mv.Viewer().preciseFitDataViewport() # fit viewer to the mesh
  mv.selectByName("Mesh 1")
   
  mv.Viewer().preciseFitDataViewport() # fit viewer to the mesh
  mv.Viewer().showSceneTree(True) # enables Scene Tree in Viewer window
  # user can manipulate with viewer window while this python is on pause
  os.system("pause")
   
  # remove all objects from scene
  mv.clearScene()
   
  # add offset mesh to scene
  mv.addMeshToScene(result_mesh, "Mesh Offset")
  mv.selectByName("Mesh Offset")
  mv.Viewer().showSceneTree(False) # disables Scene Tree in Viewer window
  # user can manipulate with viewer window while this python is on pause
  os.system("pause")
   
  # close viewer window nicely
  mv.Viewer().shutdown()
  os.system("pause")

  Viewer with scene tree
  
  Viewer without scene tree
  

  Note

  Unfortunately viewer now does not work on macOS
