Volume rendering structured grid data...

If you have a couple of methods in mind (one that is slow but produces good 
results, and one that is fast but not so great) you can always use a 
vtkLODProp3D to combine them into one "prop". You can add LODs to the 
vtkLODProp3D with independent mappers / properties, then put the whole 
thing into the renderer as one prop. It will select an LOD to render based 
on previous render times of the LODs and the allocated time it has to render.
