Overview
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.
