That will severely clutter the scene, but feel free to sudy this example: [https://examples.vtk.org/site/Cxx/Visualization/LabeledDataMapper/](https://examples.vtk.org/site/Cxx/Visualization/LabeledDataMapper/) It is based on the `vtkLabeledDataMapper` class: [VTK: vtkLabeledDataMapper Class Reference](https://vtk.org/doc/nightly/html/classvtkLabeledDataMapper.html) .
