    Default Carmack's Reverse In Doom 3 Has Work-Around

    Phoronix: Carmack's Reverse In Doom 3 Has Work-Around

    It looks like the patent issue with the open-source Doom 3 game won't severely delay the push of this code to the public. John Carmack has already worked around the legal issue within the id Tech 4 engine...

    So iD Software was forced to add EAX compatibility to Doom 3 and its engine for permission to change a total of 6 lines of code? Yes, sounds like an idiotic patent to me.

    To me what's it idiotic is that Creative could arm-twist id to use EAX. Patents should not only be publicly disclosed but be available in a nondiscriminatory fashion. There should be one price for everybody regardless of all other issues. And, of course, there should be no software patents.

    I agree with pretty much all of that, and I'll raise you a "How the heck could they even think of charging John Carmack for using something that was already called the 'Carmack's Reverse'." Also, not only should there be one price, but that price should be representative of the originality of the subject of the patent.... so in this case, $0.05 USD.

    Yup, software patents are a minefield and a pain in the backside.

    It was truly idiotic.

    I wonder what Carmack changed? There have been, for years, plenty of tutuorials on the web for stencil volumes that didn't violate the patent, so I'm not surprised it only took him a couple of days to complete this, but it sounds like he just tweaked his own code. Will be interesting to see if that is more efficient than some of the other stencil volume methods.

    I'm not a coder but so few lines of code? I wonder if that wasn't a trivial patent or something. A shame that something trivial can be patented. And then later used to sue the hell out of anybody. Or sneak in their otherwise maybe unwanted technology (EAX).
    I am also somewhat surprised that Creative seems to be still alive. I mean, they had good soundcards back at 486 DOS times but... that is now a long time ago.

    Default Where are software patents?

    Where are software patents? I can only think of 4 countries: USA, Germany, Japan and Korea.

    Why must the idiocy of 4 be imposed by force to the rest of the world?
    To me, software patents do not exist, as should be for everyone else.

    true but germany do only have hardware binding software patents.
    like Fat32 Microsoft patent or S3TC HTC patent.

    but yes you are right software patents are complete against the humanity-
