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] [-observer-z int] [-delay usecs] [-window] [-root] [-mono] [-install] [-visual visual]

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.

-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 100000, or about 1/10th second.

-observer-z int
    How far away the observer is from the center of the cube (the cube is one unit per side.) Default 5.

-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 radians. These should be small floating-point values (less than 0.05 works best.) Default: xy=0.01, xz=0.005, yw=0.01.

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.
