NAME
dizzy - a graphics demo that makes you dizzy using rotating textures
SYNOPSIS
dizzy [-f|-w width -h height] [-t switch_module] [-T options]
DESCRIPTION
dizzy is a graphics demo that rotates planes of patterns on a colored
background to make you dizzy. Textures can be cross-faded and there is
a mode that automatically changes textures, allowing Dizzy to be run as
a screensaver.
OPTIONS
-w width
--width width
-h height
--height height
Sets the window width and height.
-f
--fullscreen
Attempts to switch into a true fullscreen mode, if possible. The
window size parameters are ignored.
-a
--automode time
Automatically switches textures after a specified number of seconds
has passed. time can be fractional and the decimal separator is
always the period.
-t module
--texswitcher module
Selects the texture switching module to use. Default is Simple.
See below for available texture switchers and their descriptions.
-T option=value
--texswitcher-options option=value
Passes an option option with the value value to the selected
texture switcher. The available options depend on the texture
switcher used.
This option can be given multiple times to set multiple options.
-d module
--rotswitcher module
Selects the rotator switching module to use. Default is Simple.
See below for available texture switchers and their descriptions.
-D option=value
--rotswitcher-options option=value
Passes an option option with the value value to the selected
rotator switcher. The available options depend on the rotator
switcher used.
This option can be given multiple times to set multiple options.
-r resolution
--texture-resolution resolution
Changes the texture resolution. resolution must be a power of two.
The default value is 256.
-R resolution
--shader-resolution resolution
Changes the resolution used when rendering using shaders.
resolution must be a power of two. The default is 1024.
-z zoom
--zoom zoom
Zooms the textures. The default value is 100.
-c path
--cache-paths path
Use a different path for cached textures. This option can be
specified multiple times.
-C
--disable-cache
Don't use any texture cache at all.
--debug-show-planes
Zooms out of the normal view so you can see how Dizzy creates the
animation. A white border will also be drawn around the area that
would have been shown had this option not been used.
TEXTURE SWITCHERS
Simple
A simple texture switcher. It just sets the new texture when it is told
to do so. It takes no options.
Blend
A texture switcher that crossfades between textures to generate a
smooth transition. It takes one option:
blend=duration
Sets the duration of a blend to duration seconds. The value can be
fractional (the decimal separator is always a period). The default
value is 2.
Note that you have to add the time you specify here to the automode
time, so if you want the transition to take two seconds and every
image to stay for five seconds, you set the duration to 2 and
automode to 7 (not 5).
ROTATOR SWITCHERS
Simple
A simple switcher that just activates the new rotator without any
transition.
