Hi all,<br>
I've been scratching my head over this one for some time now,
searching the mailing list, but still don't have a clue:<br>
<br>
How do I manually set a z-order of a prop? In other words, I have a
prop (silhouette outline of a surface) that I want to be rendered
always in foreground. <br>
Since this is output of vtkPolyDataSilhouetteFilter, it is rendered
via vtkMapper and vtkActor and not via vtkMapper2D vtkActor2D. I
tried to visualize it via the *2D pipeline since I saw the
SetDisplayLocationToForeground() of vtkProperty2D but it did not
render correctly. <br>
<br>
I am thinking I need to traverse <a class="el"
href="http://www.vtk.org/doc/nightly/html/classvtkCullerCollection.html">vtkCullerCollection</a>
from my renderer, but then what? <br>
The class vtkCuller has only one method declared virtual double
Cull(...) with no definition.<br>
<br>
I am kind of lost here and would very much appreciate any advice on
this. <br>
Thank you!<br>
Miro
