DESCRIPTION

15       The gltext program draws some text spinning around in 3D, using a  font
16       that appears to be made of solid tubes.
17

OPTIONS

19       gltext accepts the following options:
20
21       -window Draw on a newly-created window.  This is the default.
22
23       -root   Draw on the root window.
24
25       -install
26               Install a private colormap for the window.
27
28       -visual visual
29               Specify  which  visual  to use.  Legal values are the name of a
30               visual class, or the id number (decimal or hex) of  a  specific
31               visual.
32
33       -text string
34               The  text  to  display.   This  may  contain  newlines,  but it
35               shouldn't be very long.  The default is to display the  machine
36               name and OS version.
37
38               This  may  also  be  a  format string acceptable to date(1) and
39               strftime(3), in which case, it will be updated once  a  second.
40               So  to  make this program display a spinning digital clock, you
41               could do this:
42               gltext -text "%A%n%d %b %Y%n%l:%M:%S %p"
43               To include a literal `%', you must double it: `%%'.
44
45               See the man page for strftime(3) for more details.
46
47       -program command
48               The given program is run, and  its  output  is  displayed.   If
49               specified,  this  overrides  -text.  The output of this program
50               will be repeatedely displayed, with new pages of text  shifting
51               in  every  few seconds.  Lines should be relatively short.  You
52               might try:
53               -program 'xscreensaver-text --cols 20'
54
55       -maxlines
56               Set the number of lines of text to display.  By default, gltext
57               will  print  8  lines  of  text  at a time.  Use this option to
58               increase or decrease that number.   Be  aware  that  gltext  is
59               designed to work with a fairly small amount of text, so setting
60               this value too high might result in slow performance or strange
61               behaviour stemming from buffer overflows.  Increase at your own
62               risk.
63
64       -mono   Display the text in a monospace font.  Default is  a  variable-
65               width font.
66
67       -no-mono
68               Display  the  text  in  a  variable-width  font.   This  is the
69               default.
70
71       -wander Move the text around the screen.  This is the default.
72
73       -no-wander
74               Keep the text centered on the screen.
75
76       -wander-speed
77               Sets the speed at which the text wanders  around.   Default  is
78               0.02.
79
80       -spin   Which  axes  around which the text should spin.  The default is
81               "XYZ", meaning rotate it freely  in  space.   "-spin  Z"  would
82               rotate  the  text in the plane of the screen while not rotating
83               it into or out of the screen; etc.
84
85       -no-spin
86               Don't spin the text at all: the same as -spin "".
87
88       -front  When spinning, never spin all the way around  or  upside  down:
89               always face mostly forward so that the text is easily readable.
90
91       -no-front
92               Allow  spins  to go all the way around or upside down.  This is
93               the default.
94
95       -wireframe
96               Render in wireframe instead of solid.
97
98       -fps    Display the current frame rate, CPU load, and polygon count.
99
100       -scale  Sets the scale at which the text is  rendered.   Bigger  values
101               will  result  in  bigger  text;  smaller  values will result in
102               smaller text.  The default value is 0.01.
103

ENVIRONMENT

105       DISPLAY to get the default host and display number.
106
107       XENVIRONMENT
108               to get the name of a resource file that  overrides  the  global
109               resources stored in the RESOURCE_MANAGER property.
