[vtkusers] anti-aliasing

[Mohamed Amine Mzoughi]

Hello,

I want to enable Anti-alisaing in my VTK app, so I took some parameters 
from ParaView and it still doesn't work :

     m_view->GetRenderer()->UseFXAAOn(); // enable AA

     vtkFXAAOptions* const aaOpts = m_view->GetRenderer()->GetFXAAOptions();
     aaOpts->SetRelativeContrastThreshold(0.125);
     aaOpts->SetHardContrastThreshold(0.045);
     aaOpts->SetSubpixelBlendLimit(0.75);
     aaOpts->SetSubpixelContrastThreshold(0.25);
     aaOpts->SetUseHighQualityEndpoints(true);
     aaOpts->SetEndpointSearchIterations(12);

what am I missing ?

Also, m_view->GetRenderWindow()->GetMultiSamples() => returns 8.

and I called also :

m_view->GetRenderWindow()->LineSmoothingOn();
m_view->GetRenderWindow()->PolygonSmoothingOn(); 
m_view->GetRenderWindow()->PointSmoothingOn();

Thanks.
