Pixar @ GTC 2013

Leading Engineer at Pixar Dirk van Gelder to talk OpenSubDiv at GTC.



One of the key scientists working on SubDivision Surfaces at Pixar will be talking at the GPU Technology Conference (GTC 2013) in San Jose. Dirk van Gelder (Engineering Lead, Pixar) will talk about OpenSubdiv, a new open source library for drawing subdivision surfaces with GPU acceleration that Pixar uses internally for animated feature film production.


"The key question that Ed Catmull and the team asked in the earlier years was 'How can you represent a 3D surface in a concise way. How do you make the surface look smooth but then make it controllable and designable. How do I represent that surface and make that surface look beautiful, organic and smooth, but then gives controls that you can work with? Ed Catmull posed that question in his PhD thesis in 1978, 'Recursively generated B-Spline surfaces'," says van Gelder.


SubDivision Surfaces is something Dirk van Gelder and Tony DeRose at Pixar has been working since '98. "OpenSubDiv is what we want to give away so artists can learn how to use it and standardise the engine," concludes van Gelder. "We really want to promote their use. We think they're awesome and we've been using them forever."


The PIXAR talk at GTC by Dirk van Gelder will cover, firstly a full explanation of what SubDivision Surfaces are, and then an overview of what the OpenSubDiv implementation provides. There are a bunch of examples of industry doors opened, looking at Houdini implementation, and Maya implementation and a major mobile implementation that is well under way.

GPU offers high-performance real-time display of the same surface that Pixar renders with. The same high quality PRMan renders are available as real-time with GPUs. The newly released Quadro GPU family is built on NVIDIA Kepler––the world's fastest, most efficient GPU architecture––and offers unprecedented workstation performance and capability. It brings proven technology, compatibility, and reliability to media and entertainment professionals.


Connect with experts in digital filmmaking, visual effects, and broadcast graphics at GTX 2013. With a special emphasis on media and entertainment for 2013, the NVIDIA GTC 2013 will bring together leading feature film and TV producers, visual–effects artists, post–production professionals, broadcasters, and software developers from around the world. GTC 2013 is just three weeks away and the industry luminaries’ speeches are not to be missed.
