Hi,

I have a question for redrawing a render window.
I only know the method to redraw is
vtkRenderWindow::render();
but it redraw all renderers at once.
I want to redraw only one renderer or only one actor.
Is it possible?
I divide viewport in the render window for each renderer.
One for volume rendering, and the other is something working space.
I want to redraw only working space, because volume rendering is heavy.

I looking forward your helps.

Best regards,
Jinhyeok Choi
