I have a couple questions regarding the POV-Ray with Subdivision project
(http://www.cise.ufl.edu/~xwu/Pov-Sub/).

1) Is this program made obsolete by any recent beta versions of POV-Ray 3.7?

2) Is there a way I can add conditional checks to my pov file to check
whether I am running the modified executable?

No. That is, it should still execute fine.
However, it's a modified version, the improvements in the 3.7 betas
are not in that code... I'm unsure if the authors will update POV-sub
when 3.7 comes out of beta. Note: the standard POV mesh code
is highly optimized, so IMHO it's unlikely that such extended syntax
will be adopted as standard.

Well, I guess it depends. You could write a batch file to swap the
standard executable with the modified one, and have it swap
an include file at the same time, then #include it and test the
variable you declare there.

-- file subdivision.inc
#declare SUBDIVISION = on;

-- file subdivision.bak
#declare SUBDIVISION = off;

-- file somefile.pov
#include "subdivision.inc"
#if (SUBDIVISION = on)
   // non-standard code
#else
  // standard code
#end

-- file swap_pov.bat (for DOS)
cd **povdirectory**
ren pvengine.exe pvengine.tmp
ren pvengine.bak pvengine.exe
ren pvengine.tmp pvengine.bak
ren subdivision.inc subdivision.tmp
ren subdivision.bak subdivision.inc
ren subdivision.tmp subdivision.bak

Man, I hope they do. The subdivision patch is extremely useful!

Meaning the subdivision patch? I hope that isn't true :( I want to see
it become part of the official version. It would make POV-Ray more 
useful as a modeler >> hint hint :)

I just tested the patch with the beta version. Unfortunately, the
combination is buggy. I'm unable to open files, though I am able to render
whatever file the program loads automatically.

  I don't understand how you can apply a patch to a verion of POV-Ray with
no source code.

I think most of this patch resides in it's own
executable... but a modified pvengine (3.6) is
modified to link it, I think.  Don't get those files
with the same names too confused =P

MD5 of version 3.6.1c.icl8.win32
