How to generate depth volume

[vkam]

Hello,

I am trying to figure out how best to extract "depth layers" from a built model.  What I imagine doing is, from a particular pose, sweeping a plane through the model, along the principal axis and collecting information about where the plane was intersected by points in the model.  All points falling between consecutive planes would be forced to one of the planes.  I imagine I could do this by manipulating the bounding box.  But looking for advice from the experts here.
