dymaxionmap(6)

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.
