Steffen,

use vtkImageShrink3D on you dataset

vtkImageShrink3D shrink
  shrink SetInput [reader GetOutput]
  shrink SetShrinkFactors 4 4 1
  shrink AveragingOff

works for me and my VP500!

Hi,

My Name is Steffen Oeltze and I'm doing research at the
University of Magdeburg, Germany.

I'm using VTK4.0 and the VolumePro500 board. When I try to
visualize a large volume (512x512x181) the interaction, e.g.
rotating the volume, becomes slow. I would like to use a
lower resolution of the volume during interaction as
implemented in VolView1.3.
Is there anybody who can help me with that ?

Regards,
Steffen
