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.
