[vtkusers] VTK-JS: How to visualize numbers

[Sebastien Jourdain]

The example you mention is the right approach for what you are looking for.

The reason why you don't need vtkFollowers+vtkTextActors, is that we have a
2D layer on top of the 3D for which it is trivial to render text that is
always facing the camera. ;-)
And we have a mechanism that can convert a set of location in the 3D world
into the screen space so those label could be printed.

Let us know if you the example is not enough to get you started.
