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.

-install

Install a private colormap for the window.

-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 beeing 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.

DISPLAY

to get the default host and display number.
