I still have the programs I wrote when I went through this book. The experience of bringing a 3D world to life felt like magic: you start with a black screen, draw some lines, and when you move them around in just the right way there’s suddenly a world inside the screen. It’s hard to get that same feeling today.

I think I was gifted this book for my 13th birthday so some of the math was a bit beyond me. But learning assembly and working out some of the more intricate algorithms like polygon clipping were both great training for a new programmer.
