</span>I'm also very interested in this. I'm using vtkGPUVolumeRayCastMapper,<br>
and I'm currently turning off the automatic adjustment of sample<br>
distance during interaction and resorted to doing my own simpler<br>
adjustment. I'm simply quadrupling the sample distance during<br>
interaction (for still rendering I use<br>
(spacingX+spacingY+spacingZ)/<wbr>6). I'd love to have another quality<br>
controlling knob to turn.<br>
<br>
Is there a MR up for it already? Will it be in 7.2?<br>
