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.
