You can first have a look at:
How to handle large data sets in VTK:
If this still doesn't solve your problem you can try applying a
vtkImageGaussian to turn your binary volume in a grayscale one. Thus
vtkContourFilter will work in a better way.
(I'll also recommend using vtkStripper and/or vtkLODActor)
