VTK 9.0 Offscreen Rendering

Hello,

I’m seeing a significant slowdown when rending offscreen with VTK 9.0:

ren_win.SetOffScreenRendering(1)

The rendered image looks better than the ones from <VTK9.0, however for testing purposes the renders are taking a long time. As I’m currently using the default parameters for the render window, are there any non-default parameters to speed up the render?

Thanks for all your hard work!

Do you call vtkRenderWindowInteractor::Initialize()?
I noticed reduced speed when running offscreen rendering and not calling this function.

Best,
