</div>But you can do an opposite - determine what cells are selected using vtkVisibleCellSelector.<br></div><br><div><a href="http://www.vtk.org/doc/release/5.2/html/a01496.html">http://www.vtk.org/doc/release/5.2/html/a01496.html</a><br>
<br>in theory you could make this only actor visible, find visible cells,<br>then do the same with other actors visible, then compare if all cells from the first rendering are visible in this case.<br><br><br></div><div>
Not sure how fast this would be since at least a few rendering are required.<br><br></div><div>Alex<br></div><div><br><br><br>

behind another actor it can still be picked.<br>
So I don't understand your suggestion<br>
Could you please clarify it more?<br>
<br>
Thank you,<br>
