Hi Bernhard,

You can use vtkRenderWindow::SetOffScreenRendering() to prevent the
image from being displayed on the screen. I run on Windows right now,
and this works fine. However, I believe this function is not supported
in all the different flavors of vtkRenderWindow (i.e. for other OS's).

Hope this helps,

Charles

Hi!

I use now vtkWindowToImageFilter to get an image of a polydata object.
It 
works fine. I want to speed up it. I found that this->Input->Render();
in 
vtkWindowToImageFilter.cpp costs most time. The data is rendered and is

displayed. Could it be faster if this is not displayed (if it is an
option 
the skip this part)? If yes, how can this be done?

Thanks
Bernhard
