DESCRIPTION¶

This draws one of several three dimensional parametric surfaces.

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.

--delay number

Per-frame delay, in microseconds. Default: 20000 (0.02 seconds.).

--speed number

Number of frames before changing shape. Default: 1000.

--surface random (Shortcut: --random-surface)

Display a random surface. This is the default.

--surface dini (Shortcut: --dini)

Display Dini's surface.

--surface enneper (Shortcut: --enneper)

Display Enneper's minimal surface.

--surface kuen (Shortcut: --kuen)

Display the Kuen surface.

--surface moebius (Shortcut: --moebius)

Display the Moebius strip.

--surface seashell (Shortcut: --seashell)

Display the seashell surface.

--surface swallowtail (Shortcut: --swallowtail)

Display the swallowtail catastrophe.

--surface bohemian (Shortcut: --bohemian)

Display the Bohemian dome.

--surface whitney (Shortcut: --whitney)

Display the Whitney umbrella.

--surface pluecker (Shortcut: --pluecker)

Display Pluecker's conoid.

--surface henneberg (Shortcut: --henneberg)

Display Henneberg's minimal surface.

--surface catalan (Shortcut: --catalan)

Display Catalan's minimal surface.

--surface corkscrew (Shortcut: --corkscrew)

Display the corkscrew surface.

--mode random (Shortcut: --random-mode)

Use random OpenGL primitives to display the surface. This is the default.

--mode points (Shortcut: --points)

Use OpenGL points to display the surface.

--mode lines (Shortcut: --lines)

Use OpenGL lines to display the surface.

--mode line-loops (Shortcut: --line-loops)

Use OpenGL line loops to display the surface.

--wander | --no-wander

Whether to wander around the screen.

--spin | --no-spin

Whether to rotate around the center of the figure.

--fps

Display the current frame rate, CPU load, and polygon count.

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.

SEE ALSO¶
