[vtkusers] Re: fixed-size labels in 3D

[Luca Pallozzi Lavorante]

Sorry for my last post. It was incorrect. vtkCaptionActor2D provides
fized-size labels.
The problems is that the labels cannot be occluded by other objects in the
world (depending on the viewer position, see example
Hybrid/Testing/Tcl/TestCaptionActor.tcl). Is it possible to do that?

  Thanks
