Pixar goes open source
A few days ago at SIGGRAPH 12 conference, Pixar presented their latest hot technology called Open Subdiv. This is what Pixar uses in all their videos enjoying extreme flexibility that they can achieve with any kind of mesh topology through Subdivision Surfaces. This method is very efficient to model smooth shapes, such as a round face for a human character. For this task subdivision surfaces ensure that you always get an exactly rounded shape without any
sharp or polygonal edges. In addition, this is very important for facial expressions because a clean look is much easier to read the emotions. That’s why Pixar’s short films are so famous and successive — because audience fully understands the behaviour of the character.
Open Subdiv is very powerful performance wise. It supports GPU compute for Tessellation and internal computing through CUDA, while others are also supported, such as OpenCL, GLSL and OpenMP on CPU trying to be as versatile as possible — as well as multiplatform. Thus you can use Maya (Linux version) to do all the workspace running a modern PC at decent speed at an interactive framerate. To simply put, you can deform your object without losing FPS.
Open Subdiv it’s on the trees, on the birds, on the bears, it’s on everything in Pixar’s films; and now it’s free to use! Pixar is now legally granting license to all necessary SubDivision patterns because they have decided it is more important for the industry to be able to share this technology without messing around with intellectual property issues. If you can’t wait longer, Open Subdiv it’s currently available on github and it’s still on beta due to some optimisation problems.
All in all you are able to use Open Subdiv for your project using any 3rd party animation, modelling and painting application (e.g. Blender). Pixar claimed that they want the whole ecosystem of applications to be consisted and available for everyone. Take a look to the presentation bellow to fully release what Open Subdiv is all about.

Larry Page is not being completely honest! The manner in which the PRISM program/project works does not need access from company administrators or owners, so called “direct access”; the access to the information is already there. These tech company CEOs take for granted the actual intelligence of most end users of their products. All it takes is a little digging and reading to go from ignorant to informed on these things especially on exactly how the internet works/functions in the U.S.A. I find Larry Page’s remarks just as laughable as Al Gore’s claim to “inventing” the internet/world wide web!
If you, as an end user, are reading this post; I challenge you to research these matters yourself. It really is quite simple with all the “information sites” that exist on the web today ie Wikipedia, & other online encyclopedias that actually list source material, as well as highly respected tech sites and blogs that also list their source material. Be warned: this is only the tip of the iceberg and these tech CEOs know and understand this; they are scrambling in attempt to perform DAMAGE CONTROL to save the company and what little trust thay have left from their products end users/consumers.
Am I a skeptic? I believe someone has to be or needs to be at this point in time! If your not just a little skeptical of the government, tech companies, and the people that are in charge of these agencies and companies; you need to be, even if just a little skeptic. For your own personal protection and security! I know I was a part of this community for over 14 years!
