Pixar Demos Newly Open-Sourced OpenSubdiv Graphics Tech
An anonymous reader writes "Last week at SIGGRAPH, Pixar Animation Studios announced OpenSubdiv, an open source implementation of the Renderman subdivision surface technology, thus releasing the patents to the long standing Pixar 'secret sauce.' In addition to the offline subdivision scheme, it also includes a GPU implementation. This video demonstrates a realtime deforming subdivision surface running at 50 FPS in Maya (though it is freely available to use anywhere). The source code is available on Pixar's GitHub account."
Says the project's site: "OpenSubdiv is covered by the Microsoft Public License, and is free to use for commercial or non-commercial use. This is the same code that Pixar uses internally for animated film production."
...And this type of reaction is why more companies aren't exactly tripping over themselves to open their code.
It's free for non-commercial AND commercial use. What the fuck else do you want? Are you really that offended that their open-source rendering library has the word "Microsoft" even tangentially related to it? Do you really think they would publish it under GPLv3, which could potentially force them to open their entire codebase?
Don't look a gift horse in the mouth.
Boo hoo. All the criticisms apply equally or more to the GPL. The license seems to be about halfway between the BSD license and the LGPL. You COULD make a library out of the MSPL code and link to it from GPLed code. Unless something in the GPL forbids that.
It's pretty hypocritical to criticize a license for requiring that redistribution of the source of that code or derivatives must be under the same license and then turn around and recommend everyone use the GPL instead.
