For Disney's Big Hero 6, we were challenged to produce a world significantly more complex along with richer, more realistic lighting than our previous films. To achieve this, we developed a new path-traced renderer, Hyperion, based on a new streaming framework. The key innovation is that we use large, sorted ray batches along with deferred shading to improve performance in ray intersection and shading, enabling multi-bounce path-tracing with full material responses and textures calculated on every bounce. This presentation will provide the motivation for writing the new renderer, will describe it's key technical aspects in detail, and will recount its experience in its use on Big Hero 6.
Combining masterful artistry and storytelling with groundbreaking technology, Walt Disney Animation Studios is a filmmaker-driven animation studio responsible for creating some of the most beloved films ever made. Located in Burbank, WDAS continues to build on its rich legacy of innovation and creativity, stretching from the first fully-animated feature film, 1937's Snow White and the Seven Dwarfs, to 2013's Academy Award®-winning Frozen, the biggest animated film of all time. Among the studio's timeless creations are Cinderella, Sleeping Beauty, The Jungle Book, Beauty and the Beast, The Lion King, Tangled and the Oscar(R)-winning “Big Hero 6”.
