Carmack Rewriting Doom 3 Engine Code to Avoid Legal Troubles

November 17, 2011 -

To avoid some potential legal problems related to shadow rendering code Creative Labs apparently holds a patent to, id Software has decided to hold off on releasing the code. Rather than risking legal action, id Software co-founder John Carmack has decided to rewrite part of the Doom 3 engine's code. Yesterday it was revealed that id Software had delayed releasing the code to the public because of Bethesda's concerns of potential liability related to the Creative Labs patent.

According to a tweet from Carmack, Bethesda's lawyer's raised issues about the patent by Creative Labs for a stencil shadowing technique called “Carmack's Reverse” which was created by Carmack and other coders. id Software used the technique under contract for Doom 3, but because they are providing the source code to the public, using the technique might have caused a legal headache with Creative Labs.

Bethesda and id Software have not revealed when it will be released. Chances are, Carmack would say it will be released "when it's done."

If Carmack wrote it, how did Creative Labs end up holding the patent?

Re: Carmack Rewriting Doom 3 Engine Code to Avoid Legal Troubles

Creative Labs Patented it and Carmack independently invented it. It happens all the time in software and no one cares because patents are one of those issues that get politicians scared because the wrong move would lose them all kinds of campaign contributions.

So is this Doom 3 for the PC or consoles? Personally, Carmack needs to make up some good will with us PC gamers for him forgetting who got him to his vaulted position in life. I think Doom 3 on PC (done right, and not as a shitty console port) would make up a lot of what he's lost in my eyes.

Re: Carmack Rewriting Doom 3 Engine Code to Avoid Legal Troubles

Its the PC version. He wouldn't be able to open source the Console version because of the proprietary console code that goes into it.

Surprising that this wasn't thought about before this. I remember reading quite a bit about Creative Labs patent on this back when Doom 3 came out.

Andrew EisenNo but it is defaulting to a very low volume. Not muted though.11/20/2014 - 10:14pm
MaskedPixelanteIs anyone else experiencing this weird Youtube glitch where, no matter what you had the volume set at last time, it defaults to muted no matter what?11/20/2014 - 10:07pm
MechaTama31What was wrong with Remember Me? I liked that one... >.>11/20/2014 - 8:50pm
AvalongodI tend to see the violence and sexism issues as different. Historically we know that the violence issue is overblown. But sexism is real. Better representations of women in games WILL happen.11/20/2014 - 7:35pm
Andrew EisenAnd unless I completely missed it, there's nothing in there about "how Pokemon in general is sexist but you gotta look deep for it."11/20/2014 - 5:10pm
Andrew EisenSeriously, you're upset, irked and fearful over an opinion piece that suggests the Pokemon demo would be better with more options and a better-written female character? SERIOUSLY?!11/20/2014 - 5:07pm

Andrew EisenAre you SURE you provided the right link?11/20/2014 - 4:59pm
prh99And yeah that sucks, especially when bonuses are tied to it, but that is more a problem with crappy publisher policies and scoring in general than any discussion on what may or may no be sexism in games.11/20/2014 - 4:59pm
prh99But no one is on their legislative high horse or on the litigation war path, for that matter. The biggest effect is that a reviewer might give it a lower score and drag down their meta critic ranking.11/20/2014 - 4:56pm

Andrew EisenOh for crying out loud. Wonderkarp, I apologize for how rude this question is but seriously, did you actually read that article?11/20/2014 - 4:47pm
Wonderkarpits a stigma. people in power hear this crap and start getting on their legislative high horse. but I feel like we've already paid too much attention too a demo.11/20/2014 - 4:46pm
Andrew EisenHarm gaming how?11/20/2014 - 4:35pm
Wonderkarpcause it gets parroted around and is used by people to harm gaming like Jack Thompsons did with Violence. http://www.themarysue.com/pokemon-oras-sexism/ here's the article.11/20/2014 - 4:28pm
Andrew EisenNo idea why such an opinion would upset or irk you so I'd be interested in reading it. Got a link?11/20/2014 - 4:13pm
Wonderkarplook deep for it....reaching much. those kinds of people are what urk me.11/20/2014 - 4:07pm
WonderkarpI got upset the other day when a known feminist blog wrote a large article on how the demo to Pokemon Omega Ruby was Sexist cause you couldnt play as a girl. It was a Demo....who cares? but they went off on how Pokemon in general is sexist but you gotta11/20/2014 - 4:06pm
Andrew EisenHere's the panel that Sarkeesian quote from earlier comes from. Amazing what the proper context does, isn't it? https://www.youtube.com/watch?v=e0qxtKz2vZw11/20/2014 - 3:32pm
NeenekoSomething to keep in mind, we tend to look at physics as 'hard', but math and physics are trivial compared to soc/psych (I have worked in both), but FEELS like it should be simplier.11/20/2014 - 3:17pm
