NAME
hyperball - 2d projection of a 4d object

SYNOPSIS
hyperball [--display host:display.screen] [--foreground color] [--background color] [--xy float] [--xz float] [--yz float] [--xw float] [--yw float] [--zw float] [--delay usecs] [--window] [--root] [--window-id number] [--mono] [--install] [--visual visual] [--fps]

DESCRIPTION
The hyperball program displays a wireframe projection of a hyperball which is rotating at user-specified rates around any or all of its four axes.

OPTIONS
hyperball accepts the following options:

--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.

--mono
    If on a color display, pretend we're on a monochrome display.

--install
    Install a private colormap for the window.

--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.

--delay microseconds
    How much of a delay should be introduced between steps of the animation. Default 20000, or about 0.02 seconds.

--xw float

--xy float

--xz float

--yw float

--yz float

--zw float
    The amount that the ball should be rotated around the specified axis at each frame of the animation, expressed in 0.001 radians. These should be small floating-point values (less than 50 works best.) Default: xy=3, xz=5, yw=10.

--fps
    Display the current frame rate and CPU load.

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.
