Hi sir 
I have implemented ray casting using cuda end opengl
what i need know is to make some vkt objects  and information like camera
position orientation, and even the intractor event to be passed as inputs to
my works let me give you exmple

// vtk code

  vtkCamera *CameI = vtkCamera::New();
  CameI->SetClippingRange(0.0475,2.377);
  CameI->SetFocalPoint(0.0,0.0,0.0);
  CameI->SetPosition(0.0,0.0,-2.0);
  CameI->ComputeViewPlaneNormal();
  CameI->SetViewUp(1,0,0);
  ren1->SetActiveCamera( CameI );
  ren1->ResetCamera();
  iren->Start();

// protype of rendring in opengl context
void renderVRopengl(CameI,.....) // is tht possible ?
