Doesn't seem to be working as expected yet. I have found some problems which
I'll mention here for general reference.
1) Setting the ExtentTranslator using the function
vtkPVRenderView::SetOrderedCompositingInformation(inInfo
(closer to a billion
triangles I think!)

John,
Look at vtkStructuredGridVolumeRepresentation, It passes a ExtentTranslator
to the view. The view uses the extent translator to build the KdTree. That's
one of specifying
You are correct in that if you disable ordered composite it will disabled the
distribution and the composite ordering. The problem is that the geometry
distribution also creates a k-d tree structure that the compositing uses to
determine the visibility order. So it would not be sufficient to
Thanks Ken,
My suspicions are confirmed. I had a poke around with the ordered compositing
code (vtkOrderedCompositeDistributor et al) and saw that the BSP cuts from the
D3 filter are set to match those from the PKDTree internally. I notice that in
the BSPcuts code it says
