glcells - growing cells graphics hack
glcells [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay num] [-pause num] [-maxcells num] [-radius num] [-seeds num] [-quality num] [-minfood num] [-maxfood num] [-divideage num] [-mindist num] [-keepold] [-wireframe] [-fps]
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.
