Yes, it does. Here's a slice of the CT scan of the female cadaver
which Levoy used in his original 1988 paper. From that slice or
these scatterplots you can tell that there's two important boundaries,
from air to soft tissue, and from soft tissue to bone. And, those
two boundaries were captured in the automatically generated position
function, seen here. Remember that the zero-crossings in the
position function mark the values associated with the middle of a
boundary, halfway between two neighboring materials.
