Random moving pixels accumulate in clusters. Uses virtual screens
for frame animation. This uses basic VGA functionality and works
only in 320x200x256.
Hit
<Ctrl>-C
to abort. The bottom row shows all
'clustered' pixels (on the screen a blue circle marks the seed of the
largest cluster and its size), frames drawn, and (after some time)
average frames per second. Once the screen is filled, a new random
setup is run.
This demo is part of svgalib and can be found in the
demos/
subdirectory of the original svgalib distribution. However, it is not installed in the system
by default, s.t. it is unclear where you can find it if your svgalib was installed by some
linux distribution. Even then, when you have the demo on your system, you probably won't have
the sources s.t. it is only of limited use for you.
In case of any such problem, simply get an svgalib distribution from the net. You even
don't need to install it. Just
make
in the
demos/
subdirecty. As of this writing,
svgalib-1.2.12.tar.gz is the latest version and can be retrieved by ftp from
sunsite.unc.edu at /pub/Linux/libs/graphics
and
tsx-11.mit.edu at /pub/linux/sources/libs
which will most probably be mirrored by a site close to you.
