Hi,
Basically, this should work:
mitk::BaseRenderer* renderer =
mitk::BaseRenderer::GetInstance(m_MultiWidget->mitkWidget4->GetRenderWindow());
vtkRenderer* vtkRenderer = renderer->GetVtkRenderer();
vtkCamera* camera = vtkRenderer->GetActiveCamera();
if (camera)
{
camera->SetPosition(position[0],position[1],position[2]);
camera->SetFocalPoint(focalPoint[0], focalPoint[1],focalPoint[2]);
camera->SetViewUp(viewUp[0],viewUp[1],viewUp[2]);
}
vtkRenderer->ResetCameraClippingRange();
But notice that OpenGL coordinate system is left-handed.
Regards
Matthias

Betreff: [mitk-users] Using a vtkCamera for Augmented Reality
Hi,
I want to use the vtkCamera from a QmitkRenderWindow for Augmented reality. I
have the intrinsic and extrinsic parameters for the camera (a model of the
human eye) as a 3x4 matrix M=P*[R t], where P is a 3x3 matrix that models the
intrinsic parameters, and [R t] are the extrinsic parameters (4x4 homogenous
transform).
Please could some one help me with providing the parameters to the vtkCamera
object?
Thank you!
Yashodhan
