The Technology Behind ID's Games
orac2 writes: "The current issue of IEEE Spectrum has an article on the groundbreaking technology behind iD Software's games, from the days of Commander Keen through to Return to Castle Wolfenstein. Graphics technologies covered include the original 2-D buffer trick that made side-scrolling games on the PC feasible, as well as the more modern Raycasting and Binary Space Partition Tree techniques. Carmack is quoted extensively."
now that was a classic series. anyone remember the secret commander keen level in doom ][?
gotta love easter eggs....
Not to troll or anything -- but it did seem quite amazing. I keep thinking he was like 27 or some such.
Does anybody here have opinions as to "when you grow older, you get [better/worse] at programming"?
My life in the land of the rising sun.
In my case I found it more fun to program than to play.
"Learning is not compulsory... neither is survival."
--Dr.W.Edwards Deming
I read this in the IEEE spectrum. They kept mixing up the advances in Quake I with Quake II. They even refer to a picture of Quake II as Quake I. But, there was some interesting history nonetheless.
come on fhqwhgads
Pfew, quite a relief : iat's quite a change from Carmack being quoted intensively.
When will I end this grieving ? When will my future begin ?
"First, they decided to see if they could recreate on a PC the gaming industry's biggest hit at the time, Super Mario Brothers 3. This two-dimensional game ran on the Super Nintendo Entertainment System, which drove a regular television screen."
If they can't even get that right, how am I to believe what they say about frame buffering, Hmmmmmmmmmm?????
I'm going to go get some pie instead.
I mean, hes not only a very good programmer, he looks like a computer dork, has a phat car, and actually cares what the community thinks about his games. As was the case when there was such a backlash about fixing the bug in the engine of quake2 that produced the strafe jump, he changed it, uproar ensued, he changed it back.
Carmack embodies what every programmer and any kind of computer company should strive to be.
Carmack has embraced the platform-generic opengl, and even coded his engine to be compatible on every major os. I love you carmack, please have my love child.
I MEAN C'MON hes the one responsible for such things as the infamous railgun, and the hilarious warnings about piracy on my copied version of wolf3d, which i still play on my 386 laptop.
This one is particularly good: about binary space partition tree.
Excellent. I wish I had read it when I was 12!
In the print version they show a screenshot of Quake II and identify it as being the original Quake and they also credit Return to Castle Wolfenstein as being an id project while in fact Gray Matter Studios did the bulk of the work on it (id has been working on DOOM III).

So close and yet so far from the world's perfect ID number
I feel bad, as I only point out the errors of others to create a superficial ego for my inadequacy as a human being.
Besides, I ran out of pie.
Basically, what I got out of this article was that John Carmack is almost single-handedly responsible for all of my non-productive time over the past 10 years. Thanks John!
"There were critical points in the evolution of this stuff," Carmack says, "getting into first person at all, then getting into arbitrary 3-D, and then getting into hardware acceleration....But the critical goals have been met. There's still infinite refinement that we can do on all these different things, but...we can build an arbitrary representational world at some level of fidelity. We can be improving our fidelity and our special effects and all that. But we have the fundamental tools necessary to be doing games that are a simulation of the world."
This article highlights how far we have come as game developers. id has been the "poster child" of the game development community, with the majority of other game developers following their lead. Doom III will continue this trend.
The next generation of games is going to be outstanding!
This article gives a great view of where we can be going with new technology. How realistic will games be in 10 years? My guess is that the graphic reality will become nearly indistinguishable from real life, but the greatest innovations will be in game-play. Interfacing with a keyboard/mouse/joystick isn't realistic. Voice control and force-feedback-like technologies are the way of the future, if our computing power can support it.
Kudos to Carmack on 10 years of FPS game design. Here's to the next 10!
Good article, but the Commander Keen scrolling trick was old news by then. Lots of Apple II, Atari ST, and Amiga scrolling games did the same thing. Impressive? At the time, yes. But let's not get too carried away with giving Carmack credit for everything.
The Amiga, not the PC, pioneered almost all 2D neatness - even today, some features of the Amiga HW are unavailable on standard PC cards - particularly Amigaish smooth-scrolling. Most PC card 2D scrolling STILL sucks compared to Amiga scrolling... Why? I don't know. My theory is that while the Amiga scrolled by changing the pointers to where the screen was in memory, the PC dumb-copies entire screens. Amiga: economic 60Hz multidir in 1985. PC: brute-force 70Hz multidir in 1993. Wow.
Talk about NIH and wheel-reinvention...
Age has nothing to do with it, it's all about experience and continuing to learn. Older programmers are better as long as they continue to learn and maintain curiosity about "new stuff". Experience + current knowledge > current knowledge. The myth of older programmers not being as good is really that many older programmers stop learning. For a while they are able to outperform younger programmers due to experience but eventually their laziness catches up and they being to underperform.
Not that ID is alone, but please, just how many versions of Wolfenstein 3D do we need? Let's see, offhand, I've played that, Quake 1 and 2, Marathon 1, 2 & 3, and various other modest variations on the same old theme. Networked. Non-networked (when available.)
The only unique game out there right now is Ambrosia's Pop-Pop (in Vs. mode anyway), which isn't to say that it doesn't borrow from the past (indeed from Arcanoid, Bust-A-Move, ShufflePuck and even Street Fighter), but it does so in a unique way and doesn't duplicate the same crap that has already been beaten to death ten times over by everyone else and their sister. That and it's damn fun and you can play a match in 10 minutes or less (or more, whatever you want).

The point is that Carmack brought it to the world of PC games,

John, this post demands a response along these lines, methinks...
C'mon, give us geeks occasion for joy!
Blearf. Blearf, I say.
I don't get it. Carmack said no one had done side-scrolling on an IBM PC, you say your C=64 had it, and that the article is therefore flawed.
Your C64 was not an IBM PC. Well, mine sure wasn't anyway!

I joined Softdisk in 1995, a few years after the id guys left. The company was stunned by the success of Wolfenstein and Doom, and by Duke Nukem - also born of Softdisk alumni. It was basically a subscription software company, selling a package (card games, screen savers, etc.) on disk monthly. It was a good model for the 80's.
Softdisk tried to produce a couple of games, one called Greed (later In Pursuit of Greed) which was basically a 3D Doom-clone shooter. There was some neat technology (e.g. curved surfaces), but the art was...uh, well weak. The gameplay was decent, but there were some bugs to stomp and the ship date slipped...and slipped...and slipped. It was released, but didn't live up to the hype. The game was torn to shreds in the reviews. There was a second 3D shooter - developed totally in house, though it was basically a one-man project. The lead (only) programmer left, so it was shelved.
Softdisk finally shut down its on-disk-monthly subscription software and became an ISP/web development company. It was a necessary move, but sad since the company kicked a lot of ass in the 80's with LoadStar and Big Blue Disk.
For those interested, I ran Softdisk's online download software stores on CompuServe, Prodigy, AOL while another dude took care of eWorld. We were selling Commander Keen, Dangerous Dave, and a host of other early games the id guys produced at Softdisk. Last I checked, they were still being sold (at $19.95 a pop, even).
Wow. So in ten years we come this far. How long until our PC sims are no longer visually distinguishable from reality? Ten, Five years?
LOOK AT THE FUCKING LOGO. It's a distinct "id". Fucking christ....
First, they decided to see if they could recreate on a PC the gaming industry's biggest hit at the time, Super Mario Brothers 3. This two-dimensional game ran on the Super Nintendo Entertainment System,....
Am I retarted, but I thought Super mario brothers 3 was released for the regular NES, not the SNES...???
Carmack is only 31? Damn, I better get to work.
Search first, ask questions later.
So you're saying that a computer programmer has poor social skills and doesn't get along well with people who aren't as smart as he is? I'm shocked...SHOCKED I tell you.
He's not running for president or trying to get elected prom king. His life goal is to produce the best computer games in the world. He's been living up to that goal remarkably well for the past 12 years.
Carmack has a special place in my heart because being 24, I have quite litteraly grown up playing id games.
-B
I don't get it. Carmack said no one had done side-scrolling on an IBM PC, you say your C=64 had it, and that the article is therefore flawed.
Well, I seem to remember SOPWITH.EXE had some pretty smooth side scrolling, and that was on a REAL IBM PC. They make it out to sound like Carmack invented double buffering, he did not.
My point was that even the original IBM PC was over 6 times faster than a C64, so smooth side scrolling on it is no feat.
I've had enough abrasive sigs. Kittens are cute and fuzzy.
yeah... the um SMB 3 i believe ran on the NES not SNES... And while I'd like to believe that he invented smooth scrolling graphics i don't believe it. keepin' it real phjack

We may or may not have noticed that.
Flight Simulator pioneered this sort of limited 3D. Bruce Artwick did the original Flight Simulator on machines that didn't have enough power to fill the whole screen with a solid color in one refresh. He wrote a book about how he did it in 1985. The pain, the agony...
Artwick seems to have dropped out of game development, but Carmack keeps pushing what's possible with available hardware.
Oh really, is that so? Hmm, where did I see that, oh right, IN THE ARTICLE.
Profiting from improvements in computer speed and memory, Carmack began working on how to draw polygons with more arbitrary shapes than Wolfenstein's trapezoids. "It was looking like [the graphics engine] wouldn't be fast enough," he recalls, "so we had to come up with a new approach....I knew that to be fast, we still had to have strictly horizontal floors and vertical walls." The answer was a technique known as binary space partitioning (BSP). Henry Fuchs, Zvi Kedem, and Bruce Naylor had popularized BSP techniques in 1980 while at Bell Labs to render 3-D models of objects on screen.
(emphasis mine)
Perhaps READING THE ARTICLE would have saved you the trouble of trying to show us how smart you are.

Heres a neat analogy: Orson Wells was to film as John Carmack is to computer gamiong. Both were immensly successful in their early years (Wells directed Citizen Kane in his 20's) and created a model that was mimicked for long time.

I'm not saying he isn't a successful business man, he is. But all credit shouldn't go to him and id. Others came up with much of the technology driving the games before id did.
"iD" No.......
It's "id" dammit. id Sofware. Jeez...get it right.
The article says Super Mario Brothers 3 was made for SNES. This is wrong. It was on NES.
If there is one word i'd use to describe that comment, it would be "insightful!" ;) DIE EVIL MOD heh
beware the jabberwock, my son! the jaws that bite, the claws that catch!
It all comes down to the same trick.. Build screen in back buffer, flip memory around to display on primary buffer when done .. Repeat. Carmack didn't invent this .. I'm surprised it took someone like him to even do this, since the Amiga folks were doing it in the mid/late 80s.. And it wasn't special Amiga hardware that allowed this technique, this was just common programming technique for simple scrolling. The Amiga hardware allowed it to be taken to entirely new levels (Parallax scrolling, blitting, etc .. )..
Why people worship him, especially now, is beyond me.
Well, ummm, you have a go then. Particularly at the 1996 stuff - you have a P75 and 8Mb, render a 3d texture mapped scene at 20fps.
Dave
I write a blog now, you should be afraid.
So, rendering engine improvement is essentially incremental from here? It seems to be that way, coming from Id's last two or three offerings. This is a rather distressing for someone as forward looking as myself.
Although the fundamentals have been laid into place, there must be a way or two to leap ahead of the current generation while sacrificing something from the generic style engine such as what Id has produced. For example, if you had a game where you wandered around looking for people to scrap with, you could optimize the 1 on 1 fighting with a different networking model where you are guaranteed to only have one opponent.
Windows of advantage for things like this come and go, but they certainly do seem to exist to me.
I'm running SimCity 3000 Unlimited for Linux on my ev56 Alpha via "BinTrans".
In the local book-hoarding conservatory, land was allocated to construct the statue after-which there are currently 1,200 pigeons pirched ontop of John Carmack's head.
However, all the people in surrounding areas started chanting Bible verses about John Carmack being a false-god and allegations of idoltry spread. A vicous court-battle ensued and the property-owner decided to accept immunity only if the Statue of John Carmack was publicly destroyed with a BFG-10,000,000.
*SIGH*.
Yes, the Amiga had smooth scrolling before anyone thought to do it on the PC. It took Carmack to do it simply because he was the first to do it. It wasn't all that hard, but someone had to do it first on the PC.
The important point that many people seem to be missing is the historical aspects of teh IBM PC. While the Amiga was developed with games and multimedia (and developed after the PC, I might add), the IBM PC was designed first as a smart 3270 terminal with the ability to run local programs, and then later slightly retooled to be a "business copmputer". The original PC came with a text-only dsiplay adapter and no ability to play anything but the most primitive of sounds. This was all done very much on purpose. IBM did not want the PC to be persieved as a game box, a toy. They wanted it to be seen as a work machine, an office computer to get work done on.
IBM didn't even develope the first graphics adapter for the PC, that was a small company called Hercules. Only after the runaway success of the Hercules card did IBM bother to develope the (weak and craptastic) CGA desplay.
IBM didn't put sound or music into the PC, either. That was done by Adlib, Creative Labs and Advanced Gravis.
Also of importance is the fact that the Amiga; the Atari ST, 400, 800, etc; the C64, Apple 2, etc... is that these system all shipped with fixed graphics adapters: an Amiga programmer knew that he had a display of XxY pixels and 4096 colors to play with, or the C64 programmer knew what his display was able to doi. In the PC wordld you had MDA, CGA, EGA, and VGA. Each generation of adapter brough new abilities to the PC and programmers had to decide which minimum technology level they were going to require.
So Carmak was the first to do smooth side scrolling on the PC? Someone had to be first. If nor John Carmack, it could have been Roberta Williams.
Boobies never hurt anyone. - Sherry Glaser.
Indeed. The most obvious one (to me, at least) was the claim that gaming in the late 80s was dominated by consoles. At least in the UK, consoles barely scratched the surface of the market back then, which was utterly dominated by personal computers. The C64, Amiga, Atari ST ruled the market, and even the Spectrum was still going strong. Apart from the Atari 2600, consoles barely existed until the Sega Megadrive 2 came along in 1989, and didn't really hit the big time until around 1992.
"The invisible and the non-existent look very much alike." -- Delos B. McKown
At no time did this article ever claim that John Carmack invented BSPs or ray-tracing. He just used them in a gaming environment, which was pretty groundbreaking for games.
Carmack's skill is, and always has been, at adapting graphics display technologies to games. He hasn't invented most of teh techniques and technologies he's used in his engines. What he has done is manage to get those techniques and technologies to work effectively within the cionstraints of a gaming environment. There are a ton of rendering engines out there that kick anything John Carmack has ever done right into the dirt. But they can't render scenes fast enough to work in a gaming environment.

I seem to recall that "Descent" had arbitrary 3D (along with MAPPING!, which the Quake series simply doesn't have) way way before it ever came out in any id software games.
How come the Descent series doesn't get any respect? There's some AWESOME graphics in them thar games! Smooth indoor/outdoor transitions, even rain on your windshield, not to mention a full six degrees of freedom in moving about.
I loved those games.

Well currently I would says he is very smart, he did contribute to the advancement of PC graphics quite a bit. I remember when I first saw quake, my mouth fell to the floor at the dynamic lighting. Is it ingenius, I don't know. ingenius people usually develop something, whatever it is... should last a long time, long enough to be of use to other people I suspect. Example, theories that Newton set forth hundreds of years ago are still in use today for most standard applications, now that's genius. Will people/programmers be using the 3d solutions Carmark has come up with 10 years from now? Only time will tell...

Actually, that's exactly what I'm talking about: game-play. Improvements in AI, interface, etc.
Plus, we DO know HOW to make great AI. Neural computing, Fuzzy logic. Using brute force methods, we can make programs that beat (or at least challenge) the world's greatest chess players. The problem is computing power. Deep Blue takes a significant amount of time to calculate a move. This is acceptable in chess; it isn't in "real-time" games like an FPS.
jees, they make it sound like carmack invented smooth scrolling. that same technique was used on commodore games circa 1986. an interesting read, but they need to tone down the fawning hype.
Was DoomII really ported to an arcade machine over in the States? I remember seeing one in the Film "Grosse Point Blanke" and thought it was probably a fabrication. If it was real, it must have been a nightmare to play with a joystick and XX buttons for weapons, jump, strafe etc etc!!

On my Casio EM-500, I had 16MB of RAM in which to store the program, store my maps AND run the game. The scary thing is, that was enough. You couldn't play it on the faster StrongARM IPAQs, as the IPAQ engineers (who should all be subject to mass execution) saw fit not to support the detection of multiple button presses. However, on the little MIPS Casio chip, with its proper gamepad and buttons, it ran just fine. A game which still looks modern and can be stored and run in a total of 16MB of storage. Magic.

:) Look at many of the NeoGeo games, heh. Not to mention that when you are working on Consoles in general that 16Megabytes is considered to be a lot, remember that cartridge consoles measured games in terms of megaBITS, so many of the n64 games would (I think?) fit into 16megabytes of ram quite easily. ^_^

Gaming in the 80s *was* dominated by consoles:
:) - and the Amiga was pretty much out of the price range of most consumers at the time.
In the US/Canada and Japan, you had the original Nintendo Entertainment System. In most parts of Europe and South America, the Sega Master System. Both came out around 1985 (exact date depended on where you lived), and pretty much dominated the gaming scene in their respective areas. Other than the Amiga, there was no personal computer that could stand up to these consoles (try Super Mario Brothers for the C64 if you don't believe me
The only time game consoles HAVEN'T the dominant platform was around 1983-4, when the entire video game industry crashed hard, and Commodore and Sinclair provided us with lots of fun. Although the case could be made for the modern era of games...

"Yeah, well, Dracula called and he's coming over tonight for you and I said okay."
The game you are refering to was probabably Specter, it got away with full 3D by making the 3D window 1/6 of the screen. Lots of scrollers for the apple II, the only advantage the apple II had was page flipping built in!
A little known fact - our archivist put a build on a server for some of our testers and 'oops' - he mis-set permissions. There were loads of people continuously scanning our site for a demo and 'viola'. The game got passed around - it wasn't done, but it was getting there - and we got a LOT of unsolicited feedback. Our guys also scoured message boards for opinions, etc. The feedback was 'bad, keep working' - and we did. However, the game was a disappointment in my book - good idea, some really cool features, but...it wasn't all that.

I remember Al talking about the lawsuit and the source code. One poker night (which I played badly) Dan Tobias went on a long rant (suprise) about the whole ordeal. I share his opinion that moonlight code belonged to the programmer, not the company.
Absolutely nothing came of the source code. It sat in Jim's office unused.
I was fairly pleased with how that article turned out - when I first heard about it, I dreaded seeing a trivialized simplification of the issues, but it turned out as representative as you can be in that space.
However, I really dislike discussions of the attribution of techniques to a particular programmer. Everything is derived from things before it, and I make no claims of originality. I would say that one of my talents is the ability to be aware of what sources are feeding into my work, and be able to backtrack to them. Also, there are always lots of other possible answers for any given problem that can be made to work. BSP vs sector list, Portals vs PVS vs scan line occlusion, tilted constant Z rasterization vs block subdivision vs background divides, etc. Looked at in the proper perspective, individual techniques just aren't all that important. Sometimes it sounds like "Dude, he INVENTED needle nose pliers!!!"
Heck, I somewhat deride the very concept of originality. Creativity is just synthesis without the introspection. Lots of people will catch on that and start a rant about how Id games aren't original, but they are missing the point - it is possible to set out and develop something that will be received as "original" without ever having an "original" idea spring into your mind.
The best way to get answers is to just keep working the problem, recognizing when you are stalled, and directing the search pattern. Many of the popular notions of innovation and creativity are in some ways cop-outs that keep people from being as effective as they could be. The little document I wrote about developing a part of the shadow algorithm for Doom that Nvidia has on their website was a pretty good example of my process. Don't just wait for The Right Thing to strike you - try everything you think might even be in the right direction, so you can collect clues about the nature of the problem.
John Carmack
Mozart was just some guy that wrote songs..
Newton was just a guy who could look at the natural world and derive laws that seemed to cover what he saw (oh, and co-invent calculus too). I'm not putting Carmack up with these guys, but it's pretty easy to diminish someone's accomplishments by saying they're "just a" something....
Back in the 80s *no* computer or console had the bandwidth to scoll by copying pixels - it was always done by changing the bitmap vectors in the gfx hardware.
All ID did was use the same technique as nintendo (and I'll bet it was patented by someone, atari?) thanks to IBM, who quite obviously had designed EGA with games and scrolling in mind.
What impressed me at the time of 386s was when the C64s emulator came out, and ran commodore 64 scrolling games at pretty much full speed. They were smooth scrolling away before I noticed any native PC games scrolling smoothly. And with proper graphics instead of Commander Keen's "programmer sprites". (Hey, I can't draw either. That's why they pay an artist). I wondered at the time how they could get a layer of emulation to blit things faster than native code (I think ModeX had something to do with it, so that may be VGA rather than EGA).
I have just been learning Z80 this last week, and damn it's a cool processor! And still for sale...

I just absolutely will not sign a contract that has an intellectual property clause that claims ownership of code I develop for non-company-related projects on my own time. I've invested years learning my trade because I enjoy what I do and I won't allow that enjoyment to be crushed out of me.
Arguably such clauses mean that you cannot participate in open source projects or hell - can't develop for fun at all without your efforts being assigned to XYZ Corp. Hell, arguably you're required to give notice of any such projects or could find yourself being sued b/c the company lost a market window...blah...blah...blah.
Yes, but in chess *people* take a significant amount of time to calculate a move. It's okay that computers can't take a ton of time to decide what to do in a FPS, neither can people!
Alternate Reality: The City Was the first game I remember that had a 3D Textured viewscreen on an Apple II/c (also available for the Atari ST, C64, Amiga, and a basterdized version for the PC) The Dungeon was the sequal, and had much more visual detail.
It was also one of the first games to have a soundtrack, and lyric text synchronized to the music.

I noticed the Quake II shot being referenced as Quake... But for talking about the technology or engines does it really matter?

I disagree with this view. You cannot completely decouple originality from creativity. Even if you only combine existing ideas together: for example packages and a kernel into a distribution; a graphics engine and art into a game; or off-the-shelf parts into a rocket you no doubt have to use an introspective process to create. It is the integration process that is the invention, not its indivdual parts, because after all: the individual parts were an integration process at an earlier time to begin with until we go back in human history to where we started to bang rocks together!
Even if you had only managed to exactly synthesize another persons work but you had beaten them at market, it proves that you had thought of another idea to more effectively share your invention with the world...but you had to think to make this happen. Nothing in this world happens automatically * .
However, I believe it is the mark of a genius to claim otherwise: I was reading an article on John Frusciante of the Red Hot Chili Peppers and during the interview he was asked where he got his musical ideas. He said (and I paraphrase,) "I don't come up with anything, the music simply enters me from another dimension." I would argue however, that the process becomes so deeply introspective that you are hooked up directly to yourself at such a deep level that the creative process happens nearly automatically.
Here's a quote:
John, iD, thanks for the innovation...no matter how it happens I'm always entertained!
-AP
* : except the fundamental actions of the universe; or so it seams.
Granted, we aren't able to emulate the human brain, regardless of the amount of computing power we have. That's not necessary for modern games, though. Even in a Quake 3 Arena type game, where the "human" qualities of the opponents are highly exposed, the bots don't need completely human qualities. They just need to react in a "realistic" manner.
If I toss a rocket down the hall, they should find cover. They should chase me when I run away, etc. They don't require "human-level" intelligence to provide realistic game-play.
