Right. This is the case now; it's just a question of merging in master
changes regularly.
Anyway, done profiling. Results at:
http://dl.sv.nongnu.org/releases/glob2/profiling.tar.bz2
Looks like the two functions it used to call (perlin noise and cloud
compute (or something like that)), are now just one function (simplex
noise) with about 6% less cpu used??
Well, DynamicClouds::compute() is still there, so the (absolute) savings
seems to be down at 3%.
But on the other hand, cloud computation is done about 50% more times -
which probably means a 50% increase in the framerate?
Anyway, not 6x speed according to these measurements, but still
something :-)
The gains of eliminating floating point operations are somewhat machine
dependent...
(Fwiw, my measurements are based on a program running both the old and
new version at the same time, to ease comparison.)
