So the other day I sat down and thought to myself: self, it’s high time you learn you some of this new fancy pants AGAL that’s all the rage these days. Now, after a few days of playing around I am by no means a master at the art of shader programming, but due to the still huge lack of available material on the subject, I figured I’d share a few things I’ve learned. Please feel free to post some comments correcting me where I’m wrong as I’m bound to be. I’m hoping though, that this may help out a few folks who, like me, learned programming via actionscript and have never actually written a shader in their life. I’m not going to go into the very basics of AGAL and uploading index and vertex data. There are plenty of tutorials out there about that. And if you’re looking for a book, this one by Christer Kaitila (aka Breakdance McFunkypants) is fantastic. In fact, here, I’m only going to use the utmost basic of vertex shaders and focus entirely on fragment shaders. I know when most people start getting into shader programming they jump straight into the world of 3D. If […]
