NAME
       glblur - 3D radial blur texture fields

SYNOPSIS
       menger  [-display host:display.screen] [-visual visual] [-window] [-root] [-delay number] [-blursize number] [-no-wander] [-no-spin] [-spin
       [XYZ]] [-wireframe] [-fps]

DESCRIPTION
       This program draws a box and a few line segments, and generates a radial blur outward from it.  This creates flowing field effects.

       This is done by rendering the scene into a small texture, then repeatedly rendering increasingly-enlarged and increasingly-transparent ver-
       sions  of  that	texture  onto the frame buffer.  As such, it's quite graphics intensive: don't bother trying to run this if you don't have
       hardware-accelerated texture support.  It will hurt your machine bad.

OPTIONS
       -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.

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

       -root   Draw on the root window.

       -delay number
	       Per-frame delay, in microseconds.  Default: 10000 (0.01 seconds.).

       -blursize number
	       How many copies of the scene should be laid down to make the vapor trail.  Default: 15.	Larger numbers create smoother fields, but
	       are slower.

       -wander | -no-wander
	       Whether the object should wander around the screen.

       -spin [XYZ]
	       Around which axes should the object spin?

       -no-spin
	       None.

       -wireframe
	       Render in wireframe instead of solid.

       -fps | -no-fps
	       Whether to show a frames-per-second display at the bottom of the screen.

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.
