A new real-time Eulerian fluid simulation that uses a hybrid grid of regular cubic cells on top of a layer of tall cells above an arbitrary terrain. The method includes a novel multigrid method and several fluid solver modifications, and achieves 30fps in real-world scenarios on a modern GPU.

A two-scale method for particle-based fluids that allocates computing resources to regions of the fluid where complex flow behavior emerges. This method produces similar surface details as the single-resolution simulation while improving the efficiency.

This paper presents a method for achieving non-reflecting boundaries when animating free surface fluids. The boundaries are based on the perfectly matched layer (PML) approach and are intended to allow localized high-quality simulations of large fluid domains such as oceans.

To efficiently obtain natural-looking liquid simulations subject to art direction, this method processes approved low-resolution geometry into a "guide shape" just below the liquid surface. The final high-resolution simulation runs just a surface layer constrained by the guide, with benefits for both speed and control.

A technique for synthesizing synchronized sounds for physically based fire animations. A hybrid method simulates low-frequency flame sounds using a physics-based approach, and then uses bandwidth extension and sound-texture synthesis to synthesize fiery high-frequency details.

This new approach for acquiring high-fidelity 3D facial performances with realistic dynamic wrinkles and fine facial details leverages state-of-the-art motion capture technology and advanced 3D scanning technology of facial-performance acquisition.

A new technique for high-quality facial performance capture that leverages the repetitive structure of face motions to automatically locate frames with similar expressions, called anchor frames. High-resolution geometry is reconstructed and temporal motion is propagated in parallel using robust image-space matching between the anchor frames.

A linear face modelling approach that generalizes better to unseen data and allows click-and-drag interaction for animation. The model consists of a collection of linear submodels independently trained but related through shared boundaries. It is demonstrated on dense-face motion capture data.

This paper presents a system for performance-based character animation that enables any user to control the facial expressions of a digital avatar in real-time using a non-intrusive, commercially available 3D sensor.

ShadowDraw, a system for guiding the freeform drawing of objects. As the user draws, ShadowDraw dynamically updates a shadow image underlying the user's strokes. The shadows suggest object contours to guide the drawing process.

OverCoat is a 3D painting system that allows the user to treat the full 3D space as a canvas. Paint strokes applied in 2D are embedded in a 3D scalar field that is shaped by proxy geometry, and rendered such that the result always looks like a 2D digital painting.

Designing and shading volumetric effects in feature-films is a difficult problem. This system, modeled after the way expert artists think about participating media, allows for intuitive control and authoring of both physically accurate and non-physical, artistic volumetric effects.

This noise function suitable for non-photorealistic rendering creates random variation that moves with the objects in a scene.

A new method for simulating realistic behavior of highly deformed, interacting solids without requiring explicit representation of the objects themselves.

A new and efficient algorithm for skinning skeleton-driven physically based elasticity. The algorithm and implementation are designed for efficiency with parallelism, matrix-free solvers, and branch-free vectorized and multi-threaded SVD computation. The paper demonstrates the system on real-world examples with contact and collisions.

This asynchronous mode-level-adaptive integrator with modified staggered projections synthesizes realistic multibody contact sounds. It resolves modal vibrations in both collision and frictional contact processing stages, thereby enabling non-rigid sound phenomena such as micro-collisions, vibrational energy exchange, and contact damping.

This paper focuses on the challenging problem of simulating frictional contact between thin elastic rods. Following the seminal work by Alart and Curnier in contact mechanics, this work simultaneously models contact and exact Coulomb friction as a root-finding problem that can be simply solved using a nonsmooth Newton algorithm.

A new framework for the simulation of constrained strands, which combines Lagrangian and Eulerian approaches. The two contributions are the reduced node, whose degrees of freedom precisely match the constraint, and the Eulerian node, which allows constraint handling that is independent of the initial discretization of the strand.

This paper shows how statistical modeling techniques can be combined with physics-based modeling techniques to address the limitations of both techniques. The power of this new model is generated by a wide range of physically realistic motions that achieve goals specified by the users.

A novel framework for generating full-body animations controlled by only four 3D accelerometers that are attached to the extremities of a human actor. This approach relies on a knowledge base that consists of a large number of motion clips obtained from marker-based motion capturing.

This paper presents a new data-driven approach for image-based synthesis of realistic video animations containing user-defined human motions seen from user-defined camera views.

A technique for animating characters traversing complex dynamic environments. The method uses motion capture to construct a set of controllers to traverse low-dimensional obstacles, and then employs a space-time planner to plan out the sequence in which the controllers must be used to traverse a complex dynamic environment.

This paper presents a large number of integrated locomotion skills for real-time physics-based quadrupeds. These skills include walk, trot, pace, canter, gallop, sit, lie-down, get-up, and parameterized leaps over barriers, across gaps, and onto platforms. The simulated motions are compared to known data for a dog.

This approach to constructing composite controllers that track multiple trajectories in parallel generates both high-quality animations and natural responses to certain disturbances.

This paper describes how game theory can be used to automatically create intelligent real-time controllers for characters engaged in a competitive game. These controllers employ long-term planning, display an intelligent use of randomness, and exhibit nuanced strategies based on unpredictability, such as feints and misdirection moves.
