I am triying to use volumetric rendering in one application, it should look 
similar to what it isin VolView.
The difference is the speed -  can not make thevolume interact at the speed 
that exists in VolView.
I'm trying :
1. to use different mappers in a vtkLODProperty
2. to subsample the input data to a size of 64x64x64
3. to specify the DesiredUpdateRate in the interactor
4. to use vtkInteractorStyleTrackballCamera

Is there any other trick to speed up the interaction in a volume renderer ?
Thank you very much.
