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_MAN
AGER property.
