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:

       duration=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.

KEYBOARD COMMANDS

       Cursor left
	   Select previous available texture.

       Cursor right
	   Select next available texture.

       Cursor down
	   Select previous available rotator function.

       Cursor up
	   Select next available rotator function.

       Escape
       q   Exit Dizzy.
