 Order-Independent Transparency (OIT)
 ===
 
-An order-independent transparency demo framework, including optimizations and benchmark support. With [published strategies](http://heuristic42.com/research/) for fast sorting, this demo shows performance improvements over the basic per-pixel linked lists method of up to a factor of 5 or more.

 NOTE: I haven't had time to prettify everything (I won't argue with people calling the code a mess).
 There are makefiles for **gcc/Fedora 20** and solution/project files tested with **vs2013/Windows 7**.

 This code, and the LFB depndency, is the source code for
 *Efficient Layered Fragment Buffer Techniques* (well, updated source),
 *Backwards Memory Allocation and Improved OIT* and
-*Fast Sorting for Exact OIT of Complex Scenes* found [here](http://heuristic42.com/research/).

 This project requires the following two to be in the same directory. I.e. `/path/oit/`, `/path/lfb/` and `/path/pyarlib`.
