XBall allows the user to create 3-d shaded balls, or to write and run demo which create and manipulate the balls in various ways. Documentation is included on-line via the Help menu and is not reproduced here.
Run xball -help for a decription of the command line options
Several demo files are included with the distribution. To run all the demos, run 'run_demos'.
Most resources are available for user modification. See the XBall app-defaults file for a complete listing of widgets, Following is a list of the most useful resources: XBall*canvas.width, height The default width and height of the window in which balls bounce in. XBall.delay The amount to slow the simulation, in case the computer is too fast. A reasonable range is 0 to 200. XBall.itemWidth, itemHeight The default width and height of the balls. XBall.collide If true, balls are colliding on startup. XBall.perpetual If true, balls are perpetual on startup. XBall.haltSim If true, simulation is halted on startup. XBall.demoFile Specified the file to run as a demo on startup. XBall.rgbTxt Specified the file to load for the colors. The default file is /etc/X11/rgb.txt
