SYNOPSIS

       glsnake [--display host:display.screen] [--window] [--root] [--window-id number] [--visual
       visual] [--delay microseconds]  [--fps]  [--wireframe]  [--altcolour]  [--angvel  angular]
       [--explode distance] [--statictime milliseconds] [--yangvel angle] [--zangvel angle]

DESCRIPTION

       glsnake is an imitation of Rubiks´ Snake, using OpenGL.

OPTIONS

       glsnake accepts the following options:

       --window
               Draw on a newly-created window.  This is the default.

       --root  Draw on the root window.

       --window-id number
               Draw on the specified 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 the current frame rate, CPU load, and polygon count.

       --wireframe
               Display the snake in wireframe mode, rather than the default solid mode.

       --altcolour
               Use the alternate colour scheme for the snake.  Shape identification using  colour
               will be disabled.

       -angvel angular
               Change the speed at which the snake morphs to a new shape.

       -explode distance
               Change the distance between the nodes of a snake.

       --statictime milliseconds
               Change the time between morphs.

       --yangvel angle
               Change the angle of rotation around the Y axis per frame.

       --zangvel angle
               Change the angle of rotation around the Z axis per frame.

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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.

BUGS

       The snake will happily intersect itself while morphing (this is not a bug).

       The rotation/camera position sucks.
