Sicilia, <br>if you work in C++, let's say you have two viewports, with two corresponding instances of vtkRenderer, ren1 and ren2. Say that you want to modify ren2īs camera according to whatever interaction you perform on ren1 (via a vtkRenderWindowInteractor). The command to accomplish that is :
<br><br>ren2->SetActiveCamera(ren1->GetActiveCamera());<br><br>Hope this help <br><br> Luca<br>
