Mesh Weighted Offset

Example of mesh weighted offset

• Python

  from meshlib import mrmeshpy
   
  # Create some mesh
  mesh = mrmeshpy.makeTorus(primaryRadius=1.0,
                            secondaryRadius=0.1,
                            primaryResolution=16,
                            secondaryResolution=16)
  verts_num = mesh.points.size()
   
  # Create VertScalars obj with weights for every vertex
  scalars = mrmeshpy.VertScalars(verts_num)
  for i in range(verts_num):
      weight = abs(mesh.points.vec[i].x / 5) # Individual extra offset sizes for points
      scalars.vec[i] = weight
   
  # ===params
   
  params = mrmeshpy.WeightedPointsShellParametersMetric()
  # Algorithm is voxel based, voxel size affects performance and form of result mesh
  params.voxelSize = mrmeshpy.suggestVoxelSize(mesh, 10000)
  # common basic offset applied for all point
  # Vertex-specific weighted offsets applied after the basic one
  params.offset = 0.2
  params.dist.maxWeight = max(scalars.vec) # should always have maximum between weights provided
   
  # ===offset
  res = mrmeshpy.weightedMeshShell(mesh, scalars, params)
   
  mrmeshpy.saveMesh(res, "offset_weighted.ctm")
