[vtkusers] Offscreen rendering question

[Andreas Brüning]

Hello,

i am using VTK to develope different algorithms on Windows and C++. Until now i always visualize the results on a vtkOpenGlWin32RenderWindow. Now i have to implement an offscreen renderer. But as soon as i call OffScreenRenderingOn() in vtkOpenGlWin32RenderWindow the Render()- method needs more than ten times longer than in OnScreenRendering mode. 

Is there a way to increase the performance while using the offscreen mode or is there another way to develope an offscreen renderer?

Thanks in advance
Andi
