Learning an Inverse Rig Mapping for Character Animation
(ACM Siggraph, 2015)We propose a general, real-time solution to the inversion of the rig function - the function which maps animation data from a character's rig to its skeleton. Animators design character movements in the space of an animation ... -
Learning Reduced-Order Feedback Policies for Motion Skills
(ACM Siggraph, 2015)We introduce a method for learning low-dimensional linear feedback strategies for the control of physics-based animated characters around a given reference trajectory. This allows for learned low-dimensional state abstractions ... -
A Material Point Method for Viscoelastic Fluids, Foams and Sponges
(ACM Siggraph, 2015)We present a new Material Point Method (MPM) for simulating viscoelastic fluids, foams and sponges. We design our discretization from the upper convected derivative terms in the evolution of the left Cauchy-Green elastic ... -
Multifarious Hierarchies of Mechanical Models for Artist Assigned Levels-of-Detail
(ACM Siggraph, 2015)We present a new framework for artist driven level of detail in solid simulations. Simulated objects are simultaneously embedded in several, separately designed deformation models with their own independent degrees of ... -
A new sharp-crease bending element for folding and wrinkling surfaces and volumes
(ACM Siggraph, 2015)We present a novel sharp-crease bending element for the folding and wrinkling of surfaces and volumes. Based on a control curve specified by an artist or derived from internal stresses of a simulation, we create a piecewise ... -
Real-Time Dynamic Wrinkling of Coarse Animated Cloth
(ACM Siggraph, 2015)Dynamic folds and wrinkles are an important visual cue for creating believably dressed characters in virtual environments. Adding these fine details to real-time cloth visualization is challenging, as the low-quality cloth ... -
Resampling Adaptive Cloth Simulations onto Fixed-Topology Meshes
(ACM Siggraph, 2015)We describe a method for converting an adaptively remeshed simulation of cloth into an animated mesh with fixed topology. The topology of the mesh may be specified by the user or computed automatically. In the latter case, ... -
Simulation of Fluid Mixing with Interface Control
(ACM Siggraph, 2015)The simulation of fluid mixing under the Eulerian framework often su ers from numerical dissipation issues. In this paper, we present a mass-preserving convection scheme that o ers direct control on the shape of the ... -
Sketch Abstractions for Character Posing
(ACM Siggraph, 2015)We propose a sketch-based posing system for rigged 3D characters that allows artists to create custom sketch abstractions on top of a character's actual shape. A sketch abstraction is composed of rigged curves that form ... -
Tracking Control for Streaming Input Motion Using Segmented Foot Model
(ACM Siggraph, 2015)Motion capture data has been widely used to make realistic animation. Especially, in physics-based character simulation, motion data provides plausible reference trajectory of the character. However, it requires post-processing ... -
Trajectory-Free Reactive Stepping of Physics-based Character Using Momentum Control
(ACM Siggraph, 2015)We introduce a trajectory-free reactive stepping controller using momentum control. The controller is characterized by moving passively in the direction of external pushes without attempting to follow some prescribed ...
