Hallo,

on this webseite:
http://www-f9.ijs.si/~matevz/docs/MegaPov/megapov.html#photons
is mentioned that Nathan Kopp wrote a paper about photon maps.

Quoting:
"The paper is called Simulating Reflective and Refractive Caustics in POV-Ray
Using a Photon Map, and you can download it in zipped postscript format at
http://nathan.kopp.com/nk_photons.zip (size: about 800 KB)."

Unfortunately this website is no longer available and I can't find this
Zip-file.

Does anyone here maybe still have a copy of it or knows  how to acquire it?
I would aprreciate  it.

Regards
Elma

The Wayback Machine at archive.org is your friend.

Do you happen to know what app will display this file? At the top, it says
%!PS-Adobe-3.0
....and the next line says
%%Creator: PSCRIPT.DRV Version 4.0

Looks like a Postscript file(?)

Btw, I actually thought I had a copy of Nathan Kopp's paper in some form,
downloaded long ago; but no luck in my file searches.

The inbuilt "document viewer" in Linux Mint opens it as well.   You might be
able to use an office app in windows...   ?

Those that have a postscript printer could just try to "drop" or copy the file
to the printer to get a printout.

Some Linux distribution have a ps2pdf utility installed that can convert the
postscript file to a PDF file. See the attached PDF file, that has been
converted that way.

Thanks for the file ! I have a profane feeling that many of the statements made
in the paper are no longer relevant as of POV 3.8 aren't they?
Some pov/branch developer review where he would strike out all solved issues  or
changed behaviours may save some energy. would a lot remain useful information?

No problem.

I haven't had time to read it yet, so I don't know.
