[vtkusers] How to prevent vtkRenderWindow from drawing outside the viewports

[Xiaofeng Z]

Hi,

 

I have a rendering window containing several view ports.  There are open spaces between the view ports.  When vtkRenderWindow::Render() is called, it turns the open spaces outside of the viewports to black.  Is there a way to tell vtkRenderWindow to leave these areas intact?

 

Thanks!
Xiaofeng Zhao
