NAME

        hyperball - 2d projection of a 4d object
 

SYNOPSIS

        hyperball  [-display  host:display.screen]  [-foreground color] [-back-
        ground color] [-xy float] [-xz float]  [-yz  float]  [-xw  float]  [-yw
        float]  [-zw float] [-delay usecs] [-window] [-root] [-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.
 
        -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  radi-
                ans.  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.
