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  re-
	     sources stored in the RESOURCE_MANAGER property.

     XSCREENSAVER_WINDOW
	     The window ID to use with --root.
