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.
 
        -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.
 

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.
