After seeing Chris Huff's bucket photons i tried some tests for using
photons on large water surfaces in outdoor scenes.
Using large objects with photons turned out to be quite slow and therefore
i tried to split up the water surface into parts where photons are
calculated and where not.
See the results attached, the calculation times are:
#1:
photons: 2:06
total: 11:46
#2:
photons: 8:57
total: 22:54
#3:
photons: 1:54
total: 13:44
#4 (higher quality):
photons: 5:23
total: 21:59
This splitting up works quite well, but i wonder if it would be useful to
include support for automatizing this in povray. For example one could
specify an object and only inside this object photons are calculated.
