DESCRIPTION

       The glcells program draws cells that divide exponentially, eat and eventually die.

OPTIONS

       glcells accepts the following options:

       --window
               Draw on a newly-created window.  This is the default.

       --root  Draw on the root window.

       --window-id number
               Draw on the specified window.

       --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.

       --pause num
               Specifies the pause at the end of the animation (all  cells  dead  or  maximum  amount  of  cells
               reached). Unit is in frames, default 20.

       --maxcells num
               Specifies  the  maximum  number  of  cells  on screen (dead cells also count, even if invisible).
               Default is 800.

       --radius num
               Specifies the radius of the cells. Default is 40.

       --seeds num
               Specifies the number of cells when animation starts. Default is 1.

       --quality num
               Specifies subdivision quality of the spheres used to draw the cells [0...5]. Default is 3.

       --minfood num
               Food is ditributed randomly on the screen (Yes, the cells need to eat). This parameter  specifies
               the minimum amount of food per pixel. Default is 5.

       --maxfood num
               Food  is ditributed randomly on the screen (Yes, the cells need to eat). This parameter specifies
               the maximum amount of food per pixel. Default is 20.

       --divideage num
               Specifies the minimum age in frames a cell needs to have before being able to divide. Default  is
               20

       --mindist num
               Specifies the minimum distance between cells. Default 1.4

       --delay num
               How long to pause between frames.  Default is 20000, or 0.02 second.

       --fps   Display the current frame rate, CPU load, and polygon count.

       --wireframe
               Draw wireframe only.

       --keepold
               Dead cells stay on screen.

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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
