NAME
queens - n queens screensaver
SYNOPSIS
queens [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay microseconds] [-fps]
DESCRIPTION
The queens program solves the n-queens problem (where, in
this program, N is between 5 and 10 queens) using a
straightforward backtracking algorithm. The problem is:
how may one place N queens on an NxN chessboard such that
no queen can attack a sister?
OPTIONS
queens 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. -fps Display a run
ning tally of how many frames per second are being
rendered. In conjunction with -delay 0, this can be a useful benchmark of your GL performance.
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_MAN
AGER property.
BUGS
It's not unknown for this and other OpenGL hacks to fail
under hardware accelaration (UtahGLX) and take the X
server with them. Texture images must be 16x16 or 32x32
or 64x64 etc.
