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.

       -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.
