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-wander]   [--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 unfolded 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 imagery, 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  resources  stored  in  the
               RESOURCE_MANAGER property.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
