It was suggested that xrays would be nice, and since that is a thing I like, I did a little test.
There are a few problems I'd have to solve first. Specifically how would it be displayed. I can't just use a one sided texture, as that would give you a strange cutaway. I'd likely have to model each half as a seperate object, and hide the half closest to the camera, but then this means that if for whatever reason I wanted to show both halves, there would be a seem.
This was animated by using the control bar to drive the X and Z scale of joints that were rigged. I map the position of the control bar to a range, and use a color blend node in maya like a lerp to set the scale.
It was a lot quicker to set up then you'd think.
Again for now this is just a test, but hopefully I can end up doing something cool with it!
