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 EisenHey, remember Kung Fury? That short film that was funded via Kickstarter a few years ago? You can watch it now. I suggest you do. It's fun! https://www.youtube.com/watch?v=bS5P_LAqiVg05/28/2015 - 5:14pm
Goth_SkunkOriginally, yes. Some content was cut out in order to reduce its ratign from AO down to M, but PC users could work around that an unlock the full content by means of a patch. Which is what I did. :D05/28/2015 - 3:56pm
Andrew EisenKarp - Yes, for strong sexual content. Although the recent remaster contains all that content and was rated M.05/28/2015 - 3:54pm
Andrew EisenDepends on if you consider Hatred misrated. I haven't played the game or seen the ESRB's rating summary so I'm undecided.05/28/2015 - 3:53pm
WonderkarpDidnt Fahrenheit have an AO?05/28/2015 - 3:52pm
Matthew Wilson@AE that is why I said it seems more moral panic to me.05/28/2015 - 3:51pm
Andrew EisenMatthew - From what I've seen (just the trailers) the game is nowhere near as gory as many, many other games. But again, I'm guessing the AO rating comes from theme and tone rather than outright gore.05/28/2015 - 3:50pm
Andrew EisenKarp - It didn't show penetration or nudity.05/28/2015 - 3:50pm
WonderkarpI'd say Mortal Kombat X has more Gore and Violence than Hatred.05/28/2015 - 3:50pm
Matthew Wilsonwhat I mean by worse in this case its not more gory/violent than others.05/28/2015 - 3:48pm
WonderkarpI forget....did Hot Coffee actually show Penetration?05/28/2015 - 3:48pm
Andrew EisenKarp - The Skyrim mods are external mods. The Hot Coffee mod unlocked content on the disc. Big difference. Still, the content that was unlocked was still perfectly in line with an M rating in my opinion.05/28/2015 - 3:47pm
Andrew EisenThemes are factored into ratings, not just mechanics. Still waiting for ESRB's rating summary. Very curious to see what it has to say.05/28/2015 - 3:46pm
Matthew WilsonHatred is a top down shooter though, and isnt any worse than other top down shooters?05/28/2015 - 3:45pm
Wonderkarpyeah, San Andreases rerating was ridiculous. Why not rerate Skyrim with all its crazy sex mods out there? But yeah, ESRB is good as policing itself. 05/28/2015 - 3:45pm
Andrew EisenManhunt 2 and Hatred though? Eh, there's an argument to be made for the higher rating.05/28/2015 - 3:43pm
Andrew EisenRerating San Andreas was a mistake though. That seemed to be the result of kowtowing to public pressure.05/28/2015 - 3:42pm
Andrew EisenThere wasn't one. It's just a dumb rating.05/28/2015 - 3:42pm
WonderkarpI dont see Moral Panic with a racing game though05/28/2015 - 3:40pm
Matthew Wilson@AE when they tend to misrate games its normally because of moral panic surrounding it.05/28/2015 - 3:38pm
