Well, I've finally put together the new version of the photon patch. Go
to my website for more info:
http://nathan.kopp.com/patched.htm
Anyone who has mirrored this should update their mirrors.
If you are using layered textures with UVPov (such as the textures in
"woods.inc"), you will need to change 'filter' to 'transmit' and
'rgbf' to 'rgbt' to make the textures look the way they used to.
Soon I want to release a version of the photon patch that is part
of the superpatch (and it will only add photons, not all of my
other quirky changes). BTW, try something... change that rgbf to
rgbt and render with the official POV... see if it makes any
difference (in most cases it won't).

Thank you Nathan. Could you detail the changes that were made in
this release so I may help answer those who are bound to ask this
very question in the coming weeks ?

Photon Mapping Update
---------------------
Memory optimization: Uses less than half of the memory that it used to (46%).
Syntax changes: "density" switched to "separation", other changes (see
documentation).
Speed optimization: Probably not noticeable
New adaptive search: New thresholds employed. Read the documentation for more
information.
New features:
added max_trace_level for photons
added adc_bailout for photons
ability to turn union splitting on/off on a per-object basis (use split_union
yes/no in the union)
Bugs fixed:
no more crashes with gather greater than 300
shouldn't crash for animation anymore
area lights work as expected
spot lights work as expected
cylinder lights DO NOT work as expected - working on that
I also incorporated the lathe speed improvements from 3.1e (but not all other
3.1e stuff).
One last thing... there's a paper that I wrote (in postscript format) that
details what I did so far with photon mapping (for my directed study for
school).

Hmm, good idea for the Windows users... I compiled an earlier version on the
Mac, but with the Superpatch is is a bit more work (especially the iso
surface part of it). Please, please keep a photon patch only version as
well!!! :-)

Thanks a bunch, Nathan. Been looking forward to this addition to
UVPov.

I want to keep uvpov available. But some have requested photon mapping
in the SuperPatch, so I though I'd give that a try (save Ron some work).
UV mapping is already part of the SuperPatch.

Does it mean that there will be two patches available: one for photon
and one for the uv stuff ?

PS:
I have added your background include file to the 3ds converter. Works
perfect.
