Requirement 1-3:

// calculate how far the camera should be placed
double a = renderer->GetActiveCamera()->GetViewAngle();
double b = renderer->GetActiveCamera()->GetDistance();
double c = ((3840 / 2) / tan(a / 180 * pi / 2));
renderer->GetActiveCamera()->Dolly(b / c);

Requirement 4-5:

// remove all interaction
renderWindowInteractor->RemoveAllObservers();
// hide cursor
renderWindowInteractor->HideCursor();
