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] [-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 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.

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.
