# glsnake(6x)

OpenGL enhanced Rubik's Snake cyclewaster.

## NAME

glsnake - OpenGL enhanced Rubik's Snake cyclewaster.

## 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.
