[vtk-developers] Make actor invisible, without access to actor

[Bryn Lloyd]

Hi

What I am trying to do is to make an actor of a widget invisible. Sounds 
simple...

However, since I don't have access to the actors of the widget (only the 
corresponding vtkproperty), I cannot call vtkActor::VisibilityOff(). If 
I set the actor to transparent, the application crashes.

Generally, on one machine with an AMD GFX card I am having trouble when 
using transparency. The function 'glTexImage2D' in the function 
vtkDepthPeelingPass::Render causes my application to crash. See also:

Is there some other way that I could make the actor invisible, without 
using transparency, via vtkProperty?

Thanks
