[vtkusers] Controlling left and right eye buffers

[Andrew J. Dolgert]

You can render left and right eyes explicitly.  This call to CAVELib
just alternates between the left and right eyes.

  if ( CAVELibWrap::CAVEInStereo() ) {
    if ( CAVELibWrap::CAVE_LEFT_EYE == CAVELibWrap::GetCAVEEye() )
      renWin->SetStereoTypeToLeft();
    else
      renWin->SetStereoTypeToRight();
  }
 
renWin->Render()

If you want to use VTK with CAVELib, there are some more steps, but you
could probably make your own display loop where you switch the eye to
render and switch the actor to render with each eye.
