glblur(6) XScreenSaver manual glblur(6) NAME glblur - 3D radial blur texture fields SYNOPSIS glblur [--display host:display.screen] [--visual visual] [--window] [--root] [--window-id number] [--delay number] [--blursize number] [--no-wander] [--no-spin] [--spin [XYZ]] [--fps] DESCRIPTION This program draws a box and a few line segments, and generates a ra- dial 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. 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. --window-id number Draw on the specified window. --delay number Per-frame delay, in microseconds. Default: 10000 (0.01 sec- onds.). --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. --fps Display the current frame rate, CPU load, and polygon count. 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. SEE ALSO X(1), xscreensaver(1) COPYRIGHT Copyright (C) 2002 by Jamie Zawinski.
