Looks like this file does indeed have a solid cube of samples. Each pixel is
sampled the same 20 steps with evenly spaced 5 unit increments.
Seems like this renderer is behaving like it might for a volumetric fluid
render. When rendering regular geometry, you expect a renderer to only create
a sample when a ray actually hits something, so you will only have samples
where there's geometry and they will not all be at the same Z depth.
I notice the file also has ZBack values, so there's another volumetric clue.
Geometry samples should just have a Z position and no thickness.
