Fancy that you could create the next Inside Out if you only had the right tools? Pixar just made that dream a little more realistic. Mere months after giving away Renderman, the studio has announced plans to open the source code for its Universal Scene Description software, which gives multiple computer animation apps a common "scene graph" to work from. It should help movie makers streamline the production process (particularly if there's more than one company involved), but it'll also be a boon to animation app designers who want their various programs to play together.
