Thanks for the heads up, that sounds great. I am currently working on
another project at the moment, but when I am back on our volume
rendering, I will give it a go. Is it just a case of setting the
relevant mode on vtkSmartVolumeMapper (I noticed the new setting -
OSPRayRenderMode), or is there more to it?
Thanks for all the hard work,
Ian Lindsay
