Hovertank 3D (also known as Hovertank One) was a simple drive-through-the-colored-wall maze shooter. Romero got off the phone and said, "Paul said they are doing a thing called ’texture mapping’." John Carmack looked up and to his left, thought a bit, and said, "I can do that." We then started on a path to that goal. Now John Romero, one of the four co-founders of id (along with myself, John Carmack, and Adrian Carmack – no relation) talked with Paul Neurath of Looking Glass Studios about a new game they were making (Ultima Underworld). At id software, we had enjoyed great success with our Commander Keen games, based on my childhood, my love of science fiction, and Chuck Jones’ Warner Brothers cartoons. ACHTUNG! – John Carmackįoreword by Tom Hall It all started with a phone call. Ray-casting got me where I needed to be at an acceptable cost. I wasn’t experienced enough yet to do a solid implementation of a polygon, or even line-based, engine. The choice to use ray casting was also an important pragmatic decision. Compiled scalers are a case of code specialization taken to the extreme, which, combined with the low level VGA trick of multi-column writes and the progressive performance characteristics of ray-casting make it much more even in framerate than a conventional approach. I was 21 years old when I wrote most of the code, and I had only been programming in C for a year, so it is far from a masterpiece of coding style, but there are still some things that were done well. Back then I barely trusted (with some reason!) the C standard library implementations that we had to work with, so almost everything was done in those few source files. The most remarkable thing about the project from today’s perspective is just how small it was: one little directory of code files with no external dependencies. Despite being open source, the 16-bit code and assembly language is not easy to build or experiment with, so far fewer people have looked into it than the later codebases. While often overshadowed by Doom, Wolfenstein 3D does hold a significant place in video game history, and it remains fun to run around in today, just like dropping a quarter in a Pac Man machine.
