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 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.
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.
