NAME
cloudlife - a cellular automaton based on Conway's Life
SYNOPSIS
cloudlife [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-ncolors integer] [-cycledelay microseconds] [-cycle-colors integer][-cell-size integer] [-initial-density integer] [-max-age integer]
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 col
ors. 0 to disable color cycling. Default 2. - -cycle-colors integer
- How many ticks should elapse between cycling col
ors. 0 to use just one color. Default 1. - -ncolors integer
- How many colors should be used (if possible).
Default 32. 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.
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_MAN
AGER property.
