NAME

geodesic - animates a mesh geodesic sphere.

SYNOPSIS

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

-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.
