The glcells program draws cells that divide exponentially,
eat and eventually die.
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.
- -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 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.
- XENVIRONMENT
- to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
