Once already mentioned on this blog, but now it is finally available: The Irrlicht book by Johannes Stein and Aung Sithu Kyaw, named "Irrlicht 1.7 Realtime 3D Engine Beginner's Guide
" is now available. It is a step-by-step guide to Irrlicht that starts at an easy level for beginners and then gradually works to more advanced topics.
When the book was 'in development' a year ago, I was doing the technical review for this, but after a few chapters, somehow they slowed down the work on the book, and my reviewing stopped there. So I only know the first few chapters of a maybe now edited version, but what I read then was quite ok, and felt a lot like the official Irrlicht tutorials I wrote myself. So if you are an Irrlicht beginner, I think this book might be something for you.
