NAME

6       queens - n queens screensaver
7

SYNOPSIS

9       queens  [-display  host:display.screen]  [-window]  [-root]  [-install]
10       [-visual visual] [-delay microseconds] [-wireframe] [-fps]
11

DESCRIPTION

13       The queens program solves the n-queens problem (where, in this program,
14       N  is  between  5  and  10 queens) using a straightforward backtracking
15       algorithm.  The problem is: how may one place N queens on an NxN chess‐
16       board such that no queen can attack a sister?
17

OPTIONS

19       queens 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       -wireframe
34               Render  in  wireframe instead of solid.  -fps Display a running
35               tally of how many frames per second  are  being  rendered.   In
36               conjunction  with  -delay  0, this can be a useful benchmark of
37               your GL performance.
38

ENVIRONMENT

40       DISPLAY to get the default host and display number.
41
42       XENVIRONMENT
43               to get the name of a resource file that  overrides  the  global
44               resources stored in the RESOURCE_MANAGER property.
45

BUGS

47       It's not unknown for this and other OpenGL hacks to fail under hardware
48       accelaration (UtahGLX) and take the X server with them.  Texture images
49       must be 16x16 or 32x32 or 64x64 etc.
