Start here. Work through all 5 parts. http://chrishecker.com/Miscellaneous_Technical_Articles http://chrishecker.com/Miscellaneous_Technical_Articles You'll have to implement each part yourself to understand them. It's not something that can be skimmed. But it's so worth it. After that, most of the mystery of graphics will be gone. (But not the thrill.) One of the most frustrating aspects of learning graphics programming was that most resources immediately start talking about theory. Partial derivatives of uv's and xy's, gradient values and mipmap selection, and you're just trying to draw a damn picture on a triangle. Learning from working code and implementing it yourself is a better teacher.
