(I tried to send this as a private mail to Larry Gritz but apparently,
someone at Pixar has decided that the entire Link?ping University is a
spam originating site, and I have to work around that somehow).
When rendering foo.rib from the enclosed tar file with BMRT 2.3.6b on
Solaris 2.6, P.z inside the volume shader is 6 and I.z = 6, which
seems consistent with the (visibility) ray entering the volume at P-I
and leaving it at P.
However, when rendering bar.rib, P.z is still 6, while I.z is
"infinity". Since the ray enters the volume at the polygon (z = 6) and
never leaves it, I was expecting P.z = "very large" and P.z - I.z = 6.
Am I missing something here?
