[vtkusers] 3D volume camera clipping help

Hello,
 
I have a 3D volume of some CT Data that works fine at the original aspect Ratio. I have some code that adjusts the aspect ratio of the volume by using the VtkReSlicer. Which works well for applying a new aspect ratio. My issue is that whenever my aspect ratio is non-Cubic I get some clipping of my volume at certain angles when it is being rotated around. I have tried using the "ResetCameraClippingRange" function, but this seems to have no effect on my Rendered volume. I know that the clipping range bounds are computed from the actor dimensions and they don't seem to change when I change the aspect ratio. Does anyone have any ideas on what I may be missing?
 
 
Some noteworthy information:
C++ application
VTK version 8.1.1
Render window is a QT openGL Widget
 
Thanks in advance,
Mark O
