Well, its not too bad. Took 48s on my work box, which is actually a pretty weak
box.
It is much slower than the glow patch, but this is to be expected with media. A
few artifacts here and there.
It is getting there, at least!

side by side MegaPov on the left, MediaGlow on the right.
Its not perfect, adn you can see the spheres in the center of the glows
reflected in the chrome sphere.
Some work to do.
It looks like the plane reflection is different in the lower portion of the
sphere as well. Wonder why...oh well.
Other than using the media glow this is the same test file which comes with
megapov: glowlits.pov.

THis is annoying, every time I get close to replicating the glow, I hit
FixedSimpleVector limit, either due to number of light sources, number of media,
or even scaling objects and media...
I'm half ready to give up and wait for megapov for 3.7, or just put a bounty out
on adding glows to Pov3.7.
Anyway, here are the latest test images, note some of these are pretty cool,
even though they don't exactly replicate the glow object.

well ... you did see the relevant threads over in p.general and the
addition I made to the documentation correct?
http://wiki.povray.org/content/Documentation:Reference_Section_4.3#Light_Sources
there IS a way around it if you're inclined towards recompiling you own
version ... if it's THAT important maybe it would be worth the effort ;-)

Yes I did see the information, and thank you for providing it. :)
Outside of the FixedSimpleVector issue, I do really like glows, so i am giving
another shot at integrating that patch with 3.7. Of course, I fully expect to
run into the FSV limit if i succeed, just because this is something i want to
use lol. :p
I keep discovering that most of what i want to do in pov runs into one limit or
another...I guess thats just my luck. ;)

From my understanding, the Do_Glow() call should go into trace.cpp,
function Trace::TraceRay(...), near line 250, right before:
if(traceLevelIncremented)
ticket.traceLevel--;
Hope this helps.
