[vtkusers] Depth peeling

[Busse, Thomas (GE Oil & Gas)]

Hi,

I tried to get depth peeling working but without success until now.

My setup is VTK6.1 and a NVidia Quadro K300m under Windows.

Here is the code snippet of the initialization:

  m_pVtkRenderWindow = pVtkMFCWindow->GetRenderWindow();
  m_pVtkRenderWindow->Register(NULL);

  m_pVtkRenderWindow->AddRenderer(m_pVtkRenderer);

  // Use Depth Peeling for transparency
  m_pVtkRenderWindow->SetAlphaBitPlanes(1);
  m_pVtkRenderWindow->SetMultiSamples(0);
  m_pVtkRenderer->SetUseDepthPeeling(1);
  m_pVtkRenderer->SetMaximumNumberOfPeels(100);
  m_pVtkRenderer->SetOcclusionRatio(0.1);


but after rendering a call to
  int depthPeelingWasUsed = m_pVtkRenderer->GetLastRenderingUsedDepthPeeling();
returns 0.

Can someone help me on this?
Is there some additional trick required to get it working?

According specs the graphics card should fulfill all requirements.

Best Regards,
Thomas
