[IGSTK-Users] Augmented Reality Z-Buffer Question

Hello,

I'm trying to achieve an augemented reality effect with VTK, but the  
hidden line/surface removal gives me some headache.

I have a virtual representation of a real object and a polyline which  
is supposed to be displayed as part of the augemented reality. How  
would I setup VTK to not render the polyline when it would be  
invisible (occluded) by the real object?

Is there a way to add the representation of the real object to the  
depth buffer, even though its opacity is actually set to 0? Are there  
other solutions to this problem?

Thank you very much!

Jochen
