Excellent book if you're looking to understand the foundations of 2D & 3D graphics / game dev, although the topics covered have even more broad applications. I had quite a bit of experience with C/C++ going into it but no experience with game programming / math. I went through the book cover-to-cover when it was first published. Did all the exercises. Ran and stepped through all the code. Came away from it with a solid understanding of the basics and could have written a simple game engine I believe. I went on to tinker with a few real game engines and the knowledge gained from this book made it easier to get started with them. Highly recommended. Excited to see it updated and available online.
