See you are using the fixed-function pipeline, though. You probably know that most of the interesting 3D stuff is happening in shaders these days, right? I was reluctant, at first, to break away from my fixed-function crutch – especially since most tutorials on the Web still use it in their examples. But, I forked out some money for a book (OpenGL Superbible, 5th ed.), found some nice tutorials on the web (http://duriansoftware.com/joe/An-intro-to-modern-OpenGL.-Table-of-Contents.html and http://www.arcsynthesis.org/gltut/) and really haven’t looked back since. There has been a lot to re-learn, and I am not exactly the quickest learner on the block, but learning shaders is fundamentally learning how those dedicated 3D graphics card-thingy’s work. Interesting stuff, it is.

Not that I have written anything interesting, mind you. With a five-year old and a full-time job that has nothing to do with programming I average a line of code a week, so all I’ve got going at the moment is a rotating triangle (not even 3D!). I could probably have more working if I wasn’t so obsessively trying to develop a macro to automagically compile and link shaders written in a lisp-like language…

Keep it up! I’d be interested if you find any good linear algebra libraries. I ended up writing a poor-hacked one of my own many years ago, before the seemingly recent explosion of libraries. If nothing else, it was a good programming exercise.
