NAME
       bubbles - frying pan / soft drink simulation

SYNOPSIS
       bubbles [-display host:display.screen] [-foreground color] [-background
       color] [-window] [-root] [-mono] [-install] [-visual visual]  [-simple]
       [-broken] [-3D] [-rise|-drop] [-trails] [-fps]

DESCRIPTION
       Bubbles	sprays lots of little random bubbles all over the window which
       then grow until they reach their maximum size and go pop.  The inspira‐
       tion  for  this	was watching little globules of oil on the bottom of a
       frying pan and it also looks a little like bubbles in fizzy soft drink.
       The default mode uses fancy ray-traced bubbles but there is also a mode
       which just draws circles in case the default mode is too taxing on your
       hardware.

OPTIONS
       Depending  on  how  your bubbles was compiled, it accepts the following
       options:

       -foreground
	       Colour of circles if -simple mode is selected.

       -background
	       Colour of window background.

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

       -mono   If on a color display, pretend we're on a monochrome display.

       -install
	       Install a private colormap for the window.

       -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.

       -delay microseconds
	       How much of a delay should be introduced between steps  of  the
	       animation.   Default  800, or about 800 microsecond.  Actually,
	       this is the delay between each group of 15  new	bubbles	 since
	       such a delay between each step results in a very slow animation
	       rate.

       -nodelay
	       Same as -delay 0.

       -simple Don't use the default fancy pixmap bubbles.  Just draw  circles
	       instead.	 This may give more bearable performance if your hard‐
	       ware wasn't made for this sort of thing.

       -broken Don't hide bubbles when they pop.  This was a bug during devel‐
	       opment but the results were actually quite attractive.

       -3D     Normally,  the simulation is done completely in two dimensions.
	       When a bubble swallows up another bubble, the areas of each are
	       added  to  get  the  area of the resulting bubble.  This option
	       changes the algorithm to instead add volume (imagining each  to
	       be a sphere in 3D space).  The whole thing looks more realistic
	       but I find it attracts attention to the flickering of each bub‐
	       ble as they are move and are redrawn.  Your mileage may vary.

       -quiet  Don't print messages explaining why one or several command line
	       options were ignored.  This is disabled by default.

       -rise | -drop

       -trails

       -fps    Display the current frame rate and CPU load.

NOTES
       If you find the pace of things too slow, remember that there is a delay
       even  though you specify no -delay option.  Try using -nodelay although
       beware of the effects of irritation of  other  users  if	 you're	 on  a
       shared system as you bleed their CPU time away.

       Some  tools  to	assist	in creation of new bubbles are included in the
       source distribution.  These can either be  loaded  with	the  -file  or
       -directory  options  (if available) or they can be used in place of the
       distributed default bubble (bubble_default.c).  You might like to  copy
       these  scripts  to  a  permanent	 location  and	use  them.   Read bub‐
       bles.README.

       Rendered bubbles are not supported on  monochrome  displays.   I'm  not
       convinced  that small bubbles, even dithered properly are going to look
       like anything more than a jumble of random dots.

BUGS
       There is a delay before something appears on the screen when using ren‐
       dered  bubbles.	 The  XPM  library  seems  to take a long time to make
       pixmaps out of raw data.	 This can be irritating on slower systems.

       The movement of the bubbles looks jerky if an incomplete set of bubbles
       is used.

       The  hide/display algorithm could do with some work to avoid flickering
       when -nodelay is set.

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.
