Autodesk and Disney Pact on XGen Tech

Autodesk obtained an exclusive five-year licensing agreement for the XGen Arbitrary Primitive Generator technology (XGen), used most recently by Walt Disney Animation Studios (WDAS) in the hit animated film Tangled. XGen technology was first presented by WDAS in a research paper at SIGGRAPH in 2003 for the creation of computer-generated fur, feathers, and foliage. Since that time, XGen has been used to create the fur, hair, feathers, trees, leaves and rocks in Bolt;  the trees and bushes in UP; the dust bunnies, debris, trees, bushes, clover, and flowers in Toy Story 3; and the grass and trees in Cars 2.

In Tangled, WDAS used XGen to bring the lavish CG-animated world to life: from Rapunzel’s perfectly groomed golden locks to the film’s lush, vegetation-filled landscapes, including bushes, flowers, vines, grass, weeds, moss, thistle, ground mulch, fallen leaves, sticks, rocks, butterfly fur, airborne dust, leaves and trees, plus props such as roof tiles, arrow fletchings, a broom, and paint brushes.

XGen is a comprehensive system for generating arbitrary primitives on a surface. The system advances the state-of-the-art in the industry in several ways with its versatility, durability, and impact. XGen allows techno-artistic access to interpolation in an intuitive manner for artists, empowering them with a powerful and flexible framework for primitive generation, which is highly art directable. The genesis of XGen was a collaboration between the WDAS production and software teams to provide its artists with intuitive, creative tools for 3D animation — such as “grooming” tools for fur and hair — so that they can develop the look and feel of their characters and environments more quickly and easily. Senior Development Software Engineer at WDAS Tom Thompson was an initial creator and remains the chief architect of the software. Walt Disney Pictures’ agreement with Autodesk will enable Autodesk to make this technology available to artists to create digital entertainment.

“Twenty years ago, visual effects artists creating computer graphics were mostly mathematicians and scientists using highly technical and complex software tools that required significant amounts of custom programming,” explained CTO Andy Hendrickson, Walt Disney Animation Studios. “Back then, off-the-shelf software could not create the required details of nuance and emotion. Today, we were able to create XGen as an effective artistic tool because Autodesk provides studios like ours with comprehensive tools and a flexible, extensible platform to develop on. The Autodesk customizable toolset helps visual effects artists do their best work.”

“A key challenge in the visual effects industry continues to be the need to constantly evolve creatively while somehow controlling rapidly escalating production costs,” added Marc Petit, svp Autodesk Media & Entertainment. “To help customers better address this challenge, Autodesk has been working with industry leaders like Walt Disney Animation Studios to help them innovate faster and to make these new technologies more broadly accessible. Digital Entertainment Creation users are sure to benefit from developments designed by industry visionaries and proven in production.”

Walt Disney Animation Studios Director of Studio Technology Dan Candela said, “A primary focus for my team is to ensure that the production pipeline is streamlined in order to efficiently produce the best possible CG animation. With Autodesk’s Maya as a core piece of our toolset, we’ve developed over 100 plug-ins and extensions for the platform to enable our artists to create a movie of the quality of Tangled within necessary time and budgetary limits. Sharing our technology with the VFX and CG animation community raises the creative bar for the entire industry.”
