Hi,<br><br>I am using opencv with vtk and i have a loop for opencv to do some processing on images and using that information to modify the vtk window. However, I am not able to keep the interactor on vtk window while I run the opencv loop. <br>
<br>When I do interactor->Start(), it starts an event loop by itself and any further processing is stopped until I click "q". But after I exit the interactor by clicking 'q' I cannot do any interaction in the window like zoom in and zoom out or rotate the scene.<br>
<br>I browsed through the forums and some examples on VTK documentation and came across some ideas others have expressed.<br><br><ul><li>Using interactor->CreateRepeatingTimer()</li><li>Using mutiple threads.</li></ul>
I was wondering if anyone has some ideas on this matter, or encountered a similar issue. <br><br>Thank you.<br>Anant.<br>
