XScreenSaver !!!XScreenSaver NAME SYNOPSIS DESCRIPTION OPTIONS ENVIRONMENT SEE ALSO COPYRIGHT AUTHOR ---- !!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_MANAGER property. !!SEE ALSO X(1), xscreensaver(1) !!COPYRIGHT Copyright 2000 by Joe Keane.
