i am rendering change detection using point clouds data using vtk actors in QT GUI but i cannot interact with the window i can just load the data for change detection. i cannot zoom or rotate the point clouds and render the changed point clouds in the widow.
vtkSmartPointer UprightRenderer = vtkSmartPointer::New();
UprightRenderer->UseDepthPeelingOn();
UprightRenderer->GradientBackgroundOn();
UprightRenderer->SetBackground(0, 0, 0); // Background 2 color black
UprightRenderer->SetBackground2(1, 1, 1); // Background color white
UprightRenderer->AddActor(vtk_PC_Actor2);
UprightRenderer->ResetCamera();
vtkSmartPointer<vtkGenericOpenGLRenderWindow> renderWindowRight = vtkSmartPointer<vtkGenericOpenGLRenderWindow>::New();
renderWindowRight->AddRenderer(UprightRenderer);
ui->UpRightWidget->SetRenderWindow(renderWindowRight);
ui->UpRightWidget->GetRenderWindow()->GetRenderers()->GetFirstRenderer()->SetActiveCamera(ui->UpLeftWidget->GetRenderWindow()->GetRenderers()->GetFirstRenderer()->GetActiveCamera());
ui->UpRightWidget->GetRenderWindow()->AddObserver(vtkCommand::RenderEvent, this, &PCLViewer::ModifiedHandlerSx);
ui->UpRightWidget->GetRenderWindow()->GetRenderers()->GetFirstRenderer()->Render();
ui->UpRightWidget->GetRenderWindow()->GetInteractor()->Render();
ui->UpRightWidget->GetRenderWindow()->Render();
ui->UpRightWidget->update();
here how pass the actor to render in the window. i am getting this stack trace on the terminal.
