hyperball - 2d projection of a 4d object
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]
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.
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.
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.
How much of a delay should be introduced between steps of the animation. Default
100000, or about 1/10th second.
How far away the observer is from the center of the cube (the cube is one unit per
side.) Default 5.
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 val-
ues (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.
