There are indeed two reasons a mesh can't currently be used in an
intersection. One is that they have no inside: the "am I inside"
function for meshes always says "no." The other is that they don't
always return all intersections when asked. What we're discussing
is making those two statements no longer true. What you've found
must be a fluke. It's been done before, in POV 2.2 with heightfields
which at that time didn't have an inside either. But I wouldn't
count on it working from all angles.
