Overview
The cloudlife program draws a cellular automaton based on Conway's Life, except that cells have a maximum age, and only one pixel per cell is drawn every tick.
Options
cloudlife accepts the following options:
-
--window -
Draw on a newly-created window. This is the default.
-
--root -
Draw on the root window.
-
--window-id number -
Draw on the specified window.
-
--mono -
If on a color display, pretend we're on a monochrome display.
-
--install -
Install a private colormap for the window.
-
--visual visual -
Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.
-
--cycle-delay integer -
Time in microseconds to sleep between ticks. Default 25000.
-
--cycle-colors integer -
How many ticks should elapse between cycling colors. 0 to disable color cycling. Default 2.
-
--ncolors integer -
How many colors should be used (if possible). Default 64. The colors are chosen randomly.
-
--cell-size integer -
Size of each cell, in powers of 2. Default 3 (8-pixel cells).
-
--initial-density integer -
Percentage of cells that are alive at start and when the field is repopulated. Default 30.
-
--max-age integer -
Maximum age for a cell. Default 64.
-
--fps -
Display the current frame rate and CPU load.
Environment
-
XENVIRONMENT -
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
-
XSCREENSAVER_WINDOW -
The window ID to use with --root.
