NAME
     dymaxionmap  -  An  animation of Buckminster Fuller's unwrapped icosahedral
     globe.

SYNOPSIS
     dymaxionmap [--display host:display.screen]  [--visual  visual]  [--window]
     [--root]  [--window-id  number] [--delay number] [--speed ratio] [--no-wan-
     der] [--no-roll] [--no-stars] [--no-grid] [--flat]  [--satellite]	[--image
     file] [--image2 file] [--frames number] [--wireframe] [--fps]

DESCRIPTION
     Buckminster  Fuller's map of the Earth projected onto the surface of an un-
     folded icosahedron. It depicts the Earth's continents  as	one  island,  or
     nearly contiguous land masses.

     This  screen  saver  animates the progression of the dusk terminator across
     the flattened globe. It includes both satellite and  flat-colored	map  im-
     agery, and can load and convert other Equirectangular-projected maps.

OPTIONS
     --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.

     --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.

     --delay number
	     Per-frame delay, in microseconds.	Default: 20000 (0.02 seconds).

     --speed ratio
	     Speed  of	the  animation. 0.5 means half as fast, 2 means twice as
	     fast.

     --wander | --no-wander
	     Whether the object should wander around the screen. Default yes.

     --roll | --no-roll
	     Whether the object should roll randomly. Default yes.

     --stars | --no-stars
	     Whether to display a star field. Default yes.

     --grid | --no-grid
	     Whether to overlay a latitude/longitude grid over the map.  Default
	     yes.

     --flat  Display a flat-colored map of the Earth. This is the default.

     --satellite
	     Display a day-time satellite map of the Earth.

     --image file
	     An image to use for the day-time map.

     --image2 file
	     An  image to use for the night-time map.  The two images can be the
	     same: the night-time one will be darkened.

     --frames number
	     The number of frames  in  the  day/night  animation.  Default  720.
	     Larger  numbers  are  smoother, but use more memory.  The day/night
	     animation happens if image2 is set, or if frames is greater than 1.

     --wireframe | --no-wireframe
	     Render in wireframe instead of solid.

     --fps | --no-fps
	     Whether to show a frames-per-second display at the  bottom  of  the
	     screen.

ENVIRONMENT
     DISPLAY
	     to get the default host and display number.

     XENVIRONMENT
	     to  get  the  name of a resource file that overrides the global re-
	     sources stored in the RESOURCE_MANAGER property.

     XSCREENSAVER_WINDOW
	     The window ID to use with --root.
