NAME
     hypercube - 2d projection of a 4d object

SYNOPSIS
     hypercube [-display host:display.screen] [-foreground color]
     [-background  color]  [-color[0-7]  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 hypercube program displays a wireframe projection  of  a
     hypercube  which  is rotating at user-specified rates around
     any or all of its four axes.

OPTIONS
     hypercube 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.

     -color0 color

     -color1 color

     -color2 color

     -color3 color

     -color4 color
     -color5 color

     -color6 color

     -color7 color
             The colors used to draw the line segments  bordering
             the eight faces of the cube.  Some of the faces have
             only two of their border-lines drawn in  the  speci-
             fied color, and some have all four.

     -xw float

     -xy float

     -xz float

     -yw float

     -yz float

     -zw float
             The amount that the cube 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.
