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.
