       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 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

       -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

       -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

       -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

       -fps    Display the current frame rate, CPU load, and polygon count.

               Draw wireframe only.

               Dead cells stay on screen.


       DISPLAY to get the default host and display number.

               to get the name of a resource file that  overrides  the  global
               resources stored in the RESOURCE_MANAGER property.
