POV-Ray 3.7.beta.12a is available from http://www.povray.org/beta/. This is a
small update to beta 12 which provides significant improvement for BSP trees
on large scenes, as well as fixing a problem with missing objects. For most
scenes, the BSP tree should now provide faster renders than the default BVH.
Additionally support for the new render window has been removed, at least for
now, due to the previously-mentioned performance issues. This also means that
the EXE should work on Windows 95 again.
Changes between 3.7.beta.12 and 3.7.beta.12a
--------------------------------------------
Fixed issue with BSP that caused long build times on large trees.
Changed default BSP child access cost to 5.0 (was 1.5).
Fixed issue with BSP trees that would cause some objects to vanish.
Added an optimization which speeds up BSP renders.

You can load the appropiate DLL at runtime to execute
SetLayeredWindowAttributes if a Windows 2000 or better OS is found.
Therefore, is users use POV under Win98/Win95 it wouldn't load the
function.

I'm aware of that; I use that technique in numerous places in POVWIN.
I simply didn't bother because the feature has other issues and it was
better to just pull it out entirely.

Something that changed between 11c and 12a (didn't get to 12 in time) broke
balcony.pov - the glass is now full of clear liquid instead of purple...
Don't know quite what could cause that, but didn't see anything listed in
the changes nor known issues that jumped out at me about it. I've tried
with a few different combinations of settings (like AA on / off, the new
B2, etc) and it's the same each time.
Warp had mentioned a problem with bwstripe.pov, which is wow very different,
but I don't have a copy of 11c around anymore to tell whether it's a
difference between 3.6 and 3.7 in general or just 7.11 and 7.12; the liquid
in the glass though is definitely different between 11c and 12a, though.
Just noticed that wineglass.pov renders differently too, though the color is
still present in the liquid. The checkerboard pattern is reversed (white
and black squares are switched). Weird.

Ooooo, and +B2 breaks sombrero.pov (right half gets cut off completely!).
Wallstucco looks a little bit different, too (not related to +B2). All of
these are in scenes/advanced, btw, for those who don't know and are curious
to see.
I just redownloaded 11c, I'll put in on later tonight and see if I can find
out what's different in these renders *specifically* between 11 and 12
(most are probably 3.6->3.7 differences though, I'd guess.)

I can't tell for all the cases, but running tango.pov on 3.7 and 3.6 show huge
performance
improvement. With +b2, it's more than twice as fast as 3.6!
3.6.1 54:22
3.7 -b2 36:12
3.7 +b2 25:28
Single core single CPU.

Before anybody else asks... is there a good article somewhere that
explains what BSP is, and why it's good?

Heyy Congratulation! This method is very fast (%50). I need povray's consol
version for the adaptation to my drawing program like yafray or megapov. is
