glblur - 3D radial blur texture fields
] [-visual visual
[-window] [-root] [-delay number
] [-blursize number
[-no-wander] [-no-spin] [-spin [XYZ]
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 versions 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.
- -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.
- Draw on a newly-created window. This is the default.
- Draw on the root window.
- -delay number
- Per-frame delay, in microseconds. Default: 10000 (0.01
- -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
- -wander | -no-wander
- Whether the object should wander around the screen.
- -spin [XYZ]
- Around which axes should the object spin?
- Display the current frame rate, CPU load, and polygon
- to get the default host and display number.
- to get the name of a resource file that overrides the
global resources stored in the RESOURCE_MANAGER property.
