使用Java3D编写的生命棋游戏。可拖拽鼠标改变视角。

// Life3DConfig.java
// Andrew Davison, July 2006, [e-mail]

/* A set of controls for modifying the 7 properties managed by
   the LifeProperties object, lifeProps:
     * fullscreen: whether the Life3D appl is full-screen

     * width, height: the dimensions of the window if not full-screen

     * bgColour: the background colour used in Life3D;
                 it may be blue, green, white, or black

     * speed: the speed that the balls grid rotates;
              it may be slow, medium, or fast

     * the birth and die ranges used by the Life rules in CellsGrid. 
       A range is a series of numbers separated by spaces, each 
       number representing the number of neighbours that will trigger
       the cell's birth/death.
 
   The GUI uses:
      * a group of RadioButtons for the speed values
      * a combo box for the background colours
      * a group of two radio buttons for fullscreen and window
      * two textfields for the window's width and height
      * two textfields for the birth and die ranges
