I'm also very interested in this. I'm using vtkGPUVolumeRayCastMapper,
and I'm currently turning off the automatic adjustment of sample
distance during interaction and resorted to doing my own simpler
adjustment. I'm simply quadrupling the sample distance during
interaction (for still rendering I use
(spacingX+spacingY+spacingZ)/6). I'd love to have another quality
controlling knob to turn.

Is there a MR up for it already? Will it be in 7.2?
