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
