So there's a bit of a debate out there as to whether or not the Doom Engine, used in a variety of games, not just the original Doom, is a raycaster like Wolfenstein 3D or not. Well, after doing a bit of research, here's the definitive answer!

For more information on how the Doom Engine works, here's a very good run-down of what the source code is doing behind the scenes: http://fabiensanglard.net/doomIphone/doomClassicRenderer.php

Additional Information and Corrections:

* I couldn't think of a good way to demonstrate most of what I was talking about, as it can be difficult to intentionally create some of the potential issues the engine can run into. Fortunately, I stumbled across one just looking through random Doom levels with Doom Builder 2. Easy to see how it was missed too given all the textures in that area were primarily red. :B
