Animating Articulated Characters using Wiggly Splines
(ACM Siggraph, 2015)We propose a new framework for spacetime optimization that can generate artistic motion with a long planning horizon for complex virtual characters. The scheme can be used for generating general types of motion and neither ... -
Computational Design of Walking Automata
(ACM Siggraph, 2015)Creating mechanical automata that can walk in stable and pleasing manners is a challenging task that requires both skill and expertise. We propose to use computational design to offset the technical difficulties of this ... -
BSwarm: Biologically-Plausible Dynamics Model of Insect Swarms
(ACM Siggraph, 2015)We present a biologically plausible dynamics model to simulate swarms of flying insects. Our formulation, which is based on biological conclusions and experimental observations, is designed to simulate large insect swarms ... -
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 ... -
Hierarchical Planning and Control for Complex Motor Tasks
(ACM Siggraph, 2015)We present a planning and control framework that enables physically simulated characters to perform various types of motor tasks. To create physically-valid motion plans, our method uses a hierarchical set of simplified ... -
Hands On: Interactive Animation of Precision Manipulation and Contact
(ACM Siggraph, 2015)Humans show effortless dexterity while manipulating objects using their own hands. However, specifying the motion of a virtual character's hand or of a robotic manipulator remains a difficult task that requires animation ... -
Efficient Simulation of Knitted Cloth Using Persistent Contacts
(ACM Siggraph, 2015)Knitted cloth is made of yarns that are stitched in regular patterns, and its macroscopic behavior is dictated by the contact interactions between such yarns. We propose an efficient representation of knitted cloth at the ... -
Fully Momentum-Conserving Reduced Deformable Bodies with Collision, Contact, Articulation, and Skinning
(ACM Siggraph, 2015)We propose a novel framework for simulating reduced deformable bodies that fully accounts for linear and angular momentum conservation even in the presence of collision, contact, articulation, and other desirable effects. ... -
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 ... -
Effect of Appearance on Perception of Deformation
(ACM Siggraph, 2015)We provide an experimental validation that appearance of an object can influence the perception of its level of deformation in a 3D simulation. Our study provides helpful insights in how to improve visual plausibility of ... -
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 ... -
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 ... -
Camera Motion Graphs
(The Eurographics Association, 2014)This paper presents Camera Motion Graphs, a technique to easily and efficiently generate cinematographic sequences in real-time dynamic 3D environments. A camera motion graph consists of (i) pieces of original camera ... -
Efficient Unsupervised Temporal Segmentation of Human Motion
(The Eurographics Association, 2014)This work introduces an efficient method for fully automatic temporal segmentation of human motion sequences and similar time series. The method relies on a neighborhood graph to partition a given data sequence into distinct ... -
View-Dependent Adaptive Cloth Simulation
(The Eurographics Association, 2014)This paper describes a method for view-dependent cloth simulation using dynamically adaptive mesh refinement and coarsening. Given a prescribed camera motion, the method adjusts the criteria controlling refinement to account ... -
Strain Based Dynamics
(The Eurographics Association, 2014)We propose a new set of constraints within the Position Based Dynamics (PBD) framework that allow the control of strain in directions that are independent of the edge directions of the simulation mesh. Instead of constraining ... -
Steklov-Poincaré Skinning
(The Eurographics Association, 2014)We introduce a novel and efficient simulation technique for generating physics-based skinning animations of skeleton-driven characters with full support for collision handling. Although physics-based approaches may use a ... -
Interactive Design of Modular Tensegrity Characters
