I have lovely huge meshes made of smooth triangles, and I'm running into 
the normal inversion problem that warp talks about here: 
http://www.students.tut.fi/~warp/povQandT/SmoothTriangleArtifact/ 
(though it seems to be down atm?).  Horrible black patches.  Yuk.

I'd like to try using the double_illuminate hack, but I can't find a 
version of POV that has it!  In the version history 
(http://www.povray.org/ftp/pub/povray/Official/revision.txt), it says 
that they took double_illuminate out, but it's not in the official 3.0 
source (I'm looking in tokenize.c).  Likewise it's not in any of the 3.1 
sources I can find.  I see that double_illuminate is in Megapov 0.7, but 
Megapov doesn't have a Makefile.  Arg!  Can anyone advise me where I can 
get a version of POV, source or binary, for Linux which actually has 
double_illuminate?

Thanks!

  POV-Ray 3.5 has it, as well as MegaPov (any version).
  Even though there's currently no linux-version of 3.5 available, I don't
think you'll have to wait too long to get one.

I think that was referring to it being added to and then removed from 
the 3.1 beta, I remember something about this back on the old Compuserve 
forum.

Nathan Kopp's MegaPOV web site (http://nathan.kopp.com/patched.htm) has 
links to Linux binaries. Ken Cecka had a page for Unix/Linux, but it has 
apparently disappeared. Mark Gordon's web site has a Linux version of 
MegaPOVPlus, it is based on an older version of MegaPOV but it has the 
double_illuminate patch. A look through Google might show something, 
there are plenty of people using it under Linux.
