       hyperball - 2d projection of a 4d object


       hyperball  [-display  host:display.screen]  [-foreground color] [-back-
       ground color] [-xy float] [-xz float]  [-yz  float]  [-xw  float]  [-yw
       float]  [-zw  float] [-observer-z int] [-delay usecs] [-window] [-root]
       [-mono] [-install] [-visual visual]


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


       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 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

       -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.


       DISPLAY to get the default host and display number.

               to  get  the  name of a resource file that overrides the global
               resources stored in the RESOURCE_MANAGER property.
