[vtkusers] Stereo rendering problem with OpenGL2

[Leucht, Nicola]

Hi Aashish,

yes, would be great if you could tell me about the relevant VTK code.

Thanks,
Nicola

Hi Nicola,

I didn't spot anything obvious. Can you debug the VTK code? If yes, I can point you to the relevant VTK code.

Hi Aashish,

thanks that you already had a look at the issue!
Do you (or anyone else) have any idea what the problem might be or where I should look?

Thank you
Nicola

No, it stays there – always with two lines of the same eye.

I think its missing rendering the other eye at the center. Does it go away if you change the viewport dimensions?

Thanks,
Aashish

Your code looks fine. Can you post a screen capture of what you see?

Hi,

I’m using VTK 6.2.0 with the OpenGL2 backend.
When rendering in stereo (interlaced mode), there are two horizontal lines in the middle of the window that belong to one eye.

Code:
vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renderWindow);

vtkSmartPointer<vtkSphereSource> sphereSource = vtkSmartPointer<vtkSphereSource>::New();
sphereSource->SetCenter(0.0, 0.0, 0.0);
sphereSource->SetRadius(50.0);
sphereSource->SetPhiResolution(100);
sphereSource->SetThetaResolution(100);
vtkSmartPointer<vtkOpenGLPolyDataMapper> mapper = vtkSmartPointer<vtkOpenGLPolyDataMapper>::New();
mapper->SetInputConnection(sphereSource->GetOutputPort());

vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
mapper->Update();
renderer->AddActor(actor);
renderer->GetActiveCamera()->SetEyeAngle(30);
renderer->ResetCamera();
renderer->SetBackground(.3, .6, .3);
renderWindow->StereoCapableWindowOn();
renderWindow->SetStereoTypeToInterlaced();
renderWindow->StereoRenderOn();
renderWindowInteractor->Start();

Is there anything I need to change in my code?

Kind regards
Nicola
