I just thought I'd bring Andreas' excellent AngelCode Reference Library to public attention. It contains over 560 unique references on a huge range of topics collected from over 200 sites, covering everything from Script Engines to Terrain LOD, from AI to Encryption. It's really easy to browse the categories and locate useful articles quickly. I'm posting this because it's a very good reference for many people and yet it seems to be relatively unknown. Please, add it to your bookmarks - it's well worth checking if you need to find some information. Thanks for all of your hard work on this Andreas! [smile]
