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.
