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.
