NAME

geodesic - animates a mesh geodesic sphere.

SYNOPSIS

geodesic [--display host:display.screen] [--visual visual] [--window]
[--root] [--window-id number] [--mode mode] [--no-wander] [--no-spin]
[--fps] [--delay number] [--speed number] [--count number]

DESCRIPTION

Animates a mesh geodesic sphere of increasing and decreasing
complexity. A geodesic sphere is an icosohedron whose equilateral
faces are sub-divided into non-equilateral triangles to more closely
approximate a sphere.

The animation shows the equilateral triangles subdivided into four
coplanar equilateral triangles; and then inflated outward, causing
the sub-triangles to no longer be equilateral, but to more closely
approximate the surface of a sphere.

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.

--mode mesh | solid | stellated | stellated2 | wire
Face/edge display style. Default mesh.

--wander | --no-wander
Whether the object should wander around the screen.

--spin | --no-spin
Whether the object should spin.

--fps | --no-fps
Whether to show a frames-per-second display at the bottom of
the screen.

--delay number
Per-frame delay, in microseconds. Default: 30000 (0.03
seconds).

--speed number
Animation speed. 2.0 means twice as fast, 0.5 means half as
fast.

--count number
Depth (frequency) of the geodesic sphere. Default: 4.

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.
