Ah yes the 3d game engines of yesteryear...
http://www.maximumpc.com/article/features/3d_game_engines?page=0%2C0Doom might arguably be the most memorable (or at least the most popular) PC game of all time, and with good reason. Prior to Doom's release, programmers found themselves in the stone age of game development. For the most part, building a game meant starting from scratch and compiling all new code, but like the invention of the wheel, the advent of the game engine forever changed the PC gaming landscape.
Now, we know what you're thinking, and we're well aware that game engines existed prior to Doom's release in 1993; we're even going to cover some. But it was id Software's now legendary first-person shooter that pushed reusable 3D game engines as a viable programming model, and videogame development has never been the same since then.
On the following pages, we look back at all the major PC game engines and what made each one special. As a prerequisite, be sure to check out our history of 3D graphics, which covers videocards from the Voodoo to the GeForce and everything in between. Once you've digested these two features, you're guaranteed to have a new-found respect for gaming on the PC!
