This is an implementation of the algorithms described in our paper

	Recursive Wang Tiles for Real-Time Blue Noise
	Johannes Kopf, Daniel Cohen-Or, Oliver Deussen, Dani Lischinski
	In ACM Transactions on Graphics 25, 3 (Proc. SIGGRAPH 2006)

If you use this software for research purposes, please cite the aforementioned
paper in any resulting publication.
	
Note that this is research code, and thus partly messy, ugly, and likely to
contain bugs. We really tried to clean things up for the release version,
though. If you have any questions, please don't hesitate to ask Johannes
(kopf@inf.uni-konstanz.de). He is happy to help!

You can always find the latest versions of this code and the other supplementary
materials on our homepage:
	http://graphics.uni-konstanz.de/publications/2006/blue_noise
	
The archive includes four folders:
    * source: contains the common sources you need if you want to use our
      algorithms in your project.
    * examples: contains two projects showing how to generate and use tiles with
      the code in the source folder. Please see the separate README.TXT in the
      examples folder
    * demos: some GUI demos (executable only), please see the separate
      README.TXT in the demos folder.
    * lib: required libraries. You need to install these by yourself.

To compile the code you need the following libraries (also provided in the lib
folder, feel free to download and use the latest versions from the web instead):
    * GLEW (The OpenGL Extension Wrangler Library)
      http://glew.sourceforge.net/
    * DevIL (formerly OpenIL, an image library)
      http://openil.sourceforge.net/
    * Randoma (a library of uniform random number generators coded in assembler
      and running at insane speeds)
