Problem: The object looks noisy, even with "sturm" enabled. :-(
How can I get a smooth rendering? Is it possible for "poly" objects to
enforce some "precomputing" or the like?
I rendered with
-ibutterfly.pov +d +v -p +w800 +h600 +sp8 +ep8 +a0.1 +am2 +r3
it took 3½ minutes, with -a it took 27 seconds but looks very ugly due
to the noises. :-(
