Efficient and Controllable Fur Rendering
Walt Disney Animation Studios is seeking a graduate student with interest in fur rendering to join its project-based Summer Intern Program. The intern will work with the software group responsible for developing and supporting tools and workflows for fur rendering.
This internship offers the chance to develop photo-realistic fur shading techniques and to adapt the results for production use. The goal is to render fur more efficiently while allowing for a wide variety of fur styles and volumetric appearance.

Shape Analysis for Animation
The Animation Technology Group creates tools and processes for character animation, layout, modeling, and stereo. Our group seeks a qualified candidate to design and develop a new method for analyzing geometry by its shape, and then using this method to apply art-direction to character rigs. This method will accommodate dynamic shape changes and support real-time manipulation. This internship project will have a broad impact to the studio, especially to character rigging, animation, and cleanup.

Adaptive Material Point Simulation
Walt Disney Animation Studios is seeking a graduate student with interest in simulation and material point methods to join its project-based Summer Intern Program. The intern will work with the Technology software group responsible for developing tools for the animation pipeline.
Recently our studio has been using a snow simulator based on the material point method (MPM) (http://www.disneyanimation.com/technology/publications). Its ability to simulate dynamic elasto plastic materials effectively has inspired us to expand the use of material point methods. One key bottleneck in the execution speed of MPM methods is the reliance on a uniform grid. While this can be handled somewhat efficiently with sparse grids, we desire the ability to simulate with adaptive resolution so less active areas require less computation and vice versa. The candidate will interact closely with full-time developers and possibly artists. The internship will consist of applying and evaluating different adaptive material point techniques.
The internship will held at our Burbank, CA studio for a duration of 12 weeks beginning in he summer of 2014. Start dates can be flexible to accommodate academic schedules.

Efficient, Controllable Volumetric Cloud Rendering
Walt Disney Animation Studios is seeking a graduate student to join its project-based Summer Intern Program. The intern will work with the Technology software group responsible for developing tools for the animation pipeline.
Physically based volumetric rendering of clouds remains challenging because clouds tend to be highly scattering. The combination of forward scattering with a large albedo makes it much more challenging than other volumetric effects like smoke or fire. It typically requires dozens of bounces to get an accurate look forcing the use of scattering approximations. Our goal is to model scattering as realistically and efficiently as possible for use in our future films. This internship will explore approximations and possible improvements to performance and controllability of cloud rendering. There will be potential to perform novel research and to produce software used in production of films.

SeExpr Just-in-time Compilation
Walt Disney Animation Studios is seeking a graduate student to join its project-based Summer Intern Program. The intern will work with the Technology software group responsible for developing tools for the animation pipeline.
SeExpr (http://www.disneyanimation.com/technology/seexpr.html) is an open source expression language for enhancing the flexibility of artistic tools. We use it extensively in our software, making its performance important. The goal of this project to accelerate the evaluation of expressions by using dynamic just in time (JIT) compilation---replacing runtime interpretation. Beyond the goal of simple compilation, we must also address threading and vectorization. If time allows, a GPU compiler target will be investigated. The intern will work closely with our full- time developers to build a prototype and productize it, while at the same time contributing the result back to the open source community.The internship will held at our Burbank, CA studio for a duration of 12 weeks beginning in he summer of 2014.
