16 The \fIglcells\fP program draws cells that divide exponentially, eat and eventually die.
19 accepts the following options:
22 Draw on a newly-created window. This is the default.
25 Draw on the root window.
28 Install a private colormap for the window.
30 .B \-visual \fIvisual\fP\fP
31 Specify which visual to use. Legal values are the name of a visual class,
32 or the id number (decimal or hex) of a specific visual.
34 .B \-pause \fInum\fP\fP
35 Specifies the pause at the end of the animation (all cells dead or maximum amount of cells reached). Unit is in frames, default 20.
37 .B \-maxcells \fInum\fP\fP
38 Specifies the maximum number of cells on screen (dead cells also count, even if invisible). Default is 800.
40 .B \-radius \fInum\fP\fP
41 Specifies the radius of the cells. Default is 40.
43 .B \-seeds \fInum\fP\fP
44 Specifies the number of cells when animation starts. Default is 1.
46 .B \-quality \fInum\fP\fP
47 Specifies subdivision quality of the spheres used to draw the cells [0...5]. Default is 3.
49 .B \-minfood \fInum\fP\fP
50 Food is ditributed randomly on the screen (Yes, the cells need to eat). This parameter specifies the
51 minimum amount of food per pixel. Default is 5.
53 .B \-maxfood \fInum\fP\fP
54 Food is ditributed randomly on the screen (Yes, the cells need to eat). This parameter specifies the
55 maximum amount of food per pixel. Default is 20.
57 .B \-divideage \fInum\fP\fP
58 Specifies the minimum age in frames a cell needs to have before beeing able to divide. Default is 20
60 .B \-mindist \fInum\fP\fP
61 Specifies the minimum distance between cells. Default 1.4
64 How long to pause between frames. Default is 20000, or 0.02 second.
67 Display a running tally of how many frames per second are being rendered.
68 In conjunction with \fB\-delay 0\fP, this can be a useful benchmark of
75 Dead cells stay on screen.
80 to get the default host and display number.
83 to get the name of a resource file that overrides the global resources
84 stored in the RESOURCE_MANAGER property.
