Disney Releases 3D Texture Mapper Source Code 83

dsavi writes "Ptex, Walt Disney Animation Studio's cutting-edge 3D texture mapping library which was first used on nearly every surface in the 2008 animated feature Bolt, was released under the BSD license on Friday. Quoting the announcement on monophyl.com: 'We expect to follow Ptex with other open source projects that we hope the community will find beneficial. We will soon be launching a new Walt Disney Animation Studios Technology page under disneyanimation.com. It will include links to our open source projects as will as a library of recent publications.' This looks good for open source 3D graphics."

        Yeah... this might be some sort of miscommunication. Mickey Mouse's lawyers might not have really understood the implications of a BSD license. I wouldn't be surprised if the Ptex site disappears, nothing further ever arrives along the lines of open-source code, and Disney's lawyers attempt to find loopholes to get mirrors of the Ptex source taken down.

        Disney has always held tight controls over their IP, and while the BSD license gives them a lot of control over what *they* do with Ptex, it gives the comm

          This is a major understatement. Disney is the reason why Copyright has been extended for so long. I mean its nicknamed the Mickey Mouse Copyright act for a reason.

          • On top of that is their aggressive appropriation of endless folk tales from all cultures. They don't just lock up their ideas for eternity, they want to lock up public domain works as well.

        • Trust me, anything like this has been carefully been gone over by quite a few lawyers. Disney uses software that comes under a variety of licenses and looks at each one carefully, and they're even more careful when it comes to releasing something.

          In this case, they want the ptex file format to be used and support to become wider among apps. Releasing the libraries (especially under BSD) will make it easier for 3rd party applications to incorporate it.

        Offtopic, but your sig is wrong. Money would be equal to Work multiplied by Knowledge.

        Knowledge = Power

        Power = Work / Time

        Power = Work / Money

        Solve for Money:

        Knowledge = Work / Money

        # Multiply both sides by Work
        Work * Knowledge = Work / Money * Work

        # Work / Money * Work = Money, so:

                  You've obviously got an axe to grind. The iPhone isn't particularly open, but you might have noticed that's only one of Apple's products. Saying they're the only ones to have gained from their open source contributions is just stupid.

              Indeed. An even more worrying issue is that (which, IIRC, has happened at least once): someone could port your open source software to the Iphone, with or without your permission, and get it on the Apple Store. But if you then decide to port it yourself, Apple won't allow it on their store - thus no one will be able to run your version (except a few who have hacked their phones).

    This is great, a similar thing happened with Open EXR [openexr.com] which is an image file format for high end film production. ILM open sourced it and it was quickly picked up by other studios, which lead to the software companies implementing it.

    It seems like it's a good route for the VFX companies to take. Open source tools that are useful, then they get implemented in the main software packages which reduces your costs of maintaining plugins and a lot of custom code.

      Besides ILM and Disney, Sony has also been releasing a lot of code recently, though I don't know how good it is. OSL (open shading language) is probably the big one there.

      The purpose of this is so that other software will read/write these formats. Effects houses use lots of commercial software and free software. They also have to cooperate with *other* effects houses so limiting their own software will not help (look at the credits on the end of any big-budget movie and you will see six or more effects comp

  • Kudos to Disney for this! Very cool.

    One of the reason this is so rare, though, is that patents and IP in graphics are in a bit of a mucky muck. Companies just cross-license and forget about it, but usually that means nothing gets opened up because it's too much work to determine if they can, legally, or it's too risky, legally.
