Thank you very much for this. I'm glad there still are people writing books like this one. When I was a teenager, I found a book by L. Ammeraal which was awesome reading. It taught how to build a simple 3D graphics renderer with hidden edges removal and other interesting features. Unfortunately, back then I was a Pascal fan, so it took me some significant effort to translate bits of the code from the book from C

Later, I found another book, can't remember the author, which described even more things, like z-buffering and so on. Very interesting and very useful.
