3 dymaxionmap - An animation of Buckminster Fuller's unwrapped icosahedral globe.
6 [\-display \fIhost:display.screen\fP]
7 [\-visual \fIvisual\fP]
10 [\-delay \fInumber\fP]
20 [\-frames \fInumber\fP]
24 Buckminster Fuller's map of the Earth projected onto the surface of an
25 unfolded icosahedron. It depicts the Earth's continents as one island, or
26 nearly contiguous land masses.
28 This screen saver animates the progression of the dusk terminator across
29 the flattened globe. It includes both satellite and flat-colored map
30 imagery, and can load and convert other Equirectangular-projected maps.
33 .B \-visual \fIvisual\fP
34 Specify which visual to use. Legal values are the name of a visual class,
35 or the id number (decimal or hex) of a specific visual.
38 Draw on a newly-created window. This is the default.
41 Draw on the root window.
43 .B \-delay \fInumber\fP
44 Per-frame delay, in microseconds. Default: 20000 (0.02 seconds).
46 .B \-speed \fIratio\fP
47 Speed of the animation. 0.5 means half as fast, 2 means twice as fast.
49 .B \-wander | \-no-wander
50 Whether the object should wander around the screen. Default yes.
53 Whether the object should roll randomly. Default yes.
55 .B \-stars | \-no-stars
56 Whether to display a star field. Default yes.
59 Whether to overlay a latitude/longitude grid over the map. Default yes.
62 Display a flat-colored map of the Earth. This is the default.
65 Display a day-time satellite map of the Earth.
68 An image to use for the day-time map.
70 .B \-image2 \fIfile\fP
71 An image to use for the night-time map.
72 The two images can be the same: the night-time one will be darkened.
74 .B \-frames \fInumber\fP
75 The number of frames in the day/night animation. Default 720.
76 Larger numbers are smoother, but use more memory.
77 The day/night animation happens if \fIimage2\fP is set, or
78 if \fIframes\fP is greater than 1.
80 .B \-wireframe | \-no-wireframe
81 Render in wireframe instead of solid.
84 Whether to show a frames-per-second display at the bottom of the screen.
89 to get the default host and display number.
92 to get the name of a resource file that overrides the global resources
93 stored in the RESOURCE_MANAGER property.
