NAME

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

SYNOPSIS

dymaxionmap [-display host:display.screen] [-visual visual] [-window] [-root] [-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.

-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.
