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.
