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.
