Sorry for my last post. It was incorrect. vtkCaptionActor2D provides fized-size labels.<br>
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?<br>
<br>
Thanks <br>

Hi everybody,<br>
IŽd like to visualize labels with text information in 3D space. I verified that vtkCaptionActor2D can do it.<br>
My question is, can the label be fixed in size as I zoom in/out my scene? Could somebody give me an advice on how to do that?<br>
Should I use a vtkFollower instance? But in this case, how to rescale the label "automatically"?<br>
<br>
Thank you <br>
<br>
Luca<br>

P.S. : vtkTextActor provides a Scaled option, but the text is not positioned in the 3D world.<br>
