glblur - 3D radial blur texture fields
menger [-display host:display.screen] [-visual visual] [-window]
[-root] [-delay number] [-blursize number] [-no-wander] [-no-spin]
[-spin [XYZ]] [-wireframe] [-fps]
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 repeat-
edly 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.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
Per-frame delay, in microseconds. Default: 10000 (0.01 sec-
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.
Around which axes should the object spin?
Render in wireframe instead of solid.
-fps | -no-fps
Whether to show a frames-per-second display at the bottom of
DISPLAY to get the default host and display number.

resources stored in the RESOURCE_MANAGER property.
