Hello,

There’s this example [https://vtk.org/Wiki/VTK/Examples/Cxx/Visualization/LabeledDataMapper](https://vtk.org/Wiki/VTK/Examples/Cxx/Visualization/LabeledDataMapper) of vtkLabeledDataMapper but I don’t want to label all points, is there a way to label only a point with that class ?

If I want to create a little popup/bubble with some text and an image and place it near a point of the vtkPolyData, what’s the easiest/efficient way (strategy) to do it ?

Thanks.
