NAME
cloudlife - a cellular automaton based on Conway's Life
SYNOPSIS
cloudlife [-display host:display.screen] [-foreground color] [-back-
ground color] [-window] [-root] [-mono] [-install] [-visual visual]
[-ncolors integer] [-cycle-delay microseconds] [-cycle-colors inte-
ger][-cell-size integer] [-initial-density integer] [-max-age integer]
[-fps]
DESCRIPTION
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.
-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 dis-
able 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
DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
