Just for fun… sfmandelbrot computes the famous Mandelbrot set. See examples in rsf/rsf/fractal.

Zooming in, one can explore different fractal patterns inside the set.

Just for fun… sffern computes “fractal ferns”. See an example in rsf/rsf/fractal and an animated gif.

It its now possible to check parameters for Madagascar programs in SCons flows using CHECKPAR option like this: scons CHECKPAR=y <target> Here is what happened when I first ran an example from rsftour:

bash$ scons CHECKPAR=y 
scons: Reading SConscript files ... 
No parameter "n2" in sfwindow 
Failed on "window n2=10 min1=0.4 max1=0.8"

After fixing self-documentation for sfwindow:

bash$ scons CHECKPAR=y 
scons: Reading SConscript files ... 
No parameter "nc" in sfwiggle 
Failed on "wiggle transp=y poly=y yreverse=y pclip=100 nc=100 allpos=n "

Fixing that one requires changing the SConstruct file.

CHECKPAR is an experimental option and will be enhanced in the future to include parameter ranges and other safety checks. Another useful option is TIMER.

You can now time the execution of processing flows in Scons using a TIMER option. Use it like this:
scons TIMER=y <target>
An example from rsftour:

bash$ scons -Q TIMER=y windowed.rsf

/usr/bin/time < Txx.HH /path/to/RSF/bin/sfwindow n2=10 n1=200 f1=200 > windowed.rsf
