Ryusuke Villemin, Christophe Hery, Sonoko Konishi, Takahito Tejima, David Yu


Technology has always played an important part in Pixar's movie making process, starting with Toy Story over 20 years ago. This course will take you on a journey through that technical evolution, focusing on how story drove our technical designs and how we utilized new technical advancements to tell more appealing stories. Finally we'll focus on several fundamental changes that happened recently. Prman's long used REYES algorithm, has been replaced by RIS, a modern raytracing engine. At the same time, the shading language used for more than 20 years, RSL, was replaced by C++ and OSL shaders. Pixar's famous subdivision surface algorithm was made open-source, in order to make it available across 3D software, and promote its development at a larger scale.
