HairControl: A Tracking Solution for Directable Hair Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
We present a method for adding artistic control to physics-based hair simulation. Taking as input an animation of a coarse set of guide hairs, we constrain a subsequent higher-resolution simulation of detail hairs to follow ...
Programmable Animation Texturing using Motion Stamps
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Our work on programmable animation texturing enhances the concept of texture mapping by letting artists stylize arbitrary animations using elementary animations, instantiated at the scale of their choice. The core of our ...
Example-Based Brushes for Coherent Stylized Renderings
(Association for Computing Machinery, Inc (ACM), 2017)
Painterly stylization is the cornerstone of non-photorealistic render- ing. Inspired by the versatility of paint as a physical medium, exist- ing methods target intuitive interfaces that mimic physical brushes, providing ...
BetweenIT: An Interactive Tool for Tight Inbetweening
(The Eurographics Association and Blackwell Publishing Ltd, 2010)
The generation of inbetween frames that interpolate a given set of key frames is a major component in the production of a 2D feature animation. Our objective is to considerably reduce the cost of the inbetweening phase by ...
Efficient Simulation of Secondary Motion in Rig-Space
(ACM SIGGRAPH / Eurographics Association, 2013)
We present an efficient method for augmenting keyframed character animations with physically-simulated secondary motion. Our method achieves a performance improvement of one to two orders of magnitude over previous work ...
Iterative Image Warping
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
Animated image sequences often exhibit a large amount of inter-frame coherence which standard rendering algorithms and pipelines are ill-equipped to exploit, limiting their efficiency. To address this inefficiency we ...
CANVAS: Computer-Assisted Narrative Animation Synthesis
(The Eurographics Association, 2016)
Despite the maturity in solutions for animating expressive virtual characters, innovations realizing the creative intent of story writers have yet to make the same strides. The key challenge is to provide an accessible, ...
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 ...
Visibility Transition Planning for Dynamic Camera Control
(ACM SIGGRAPH / Eurographics Association, 2009)
We present a real-time camera control system that uses a global planning algorithm to compute large, occlusion free camera paths through complex environments. The algorithm incorporates the visibility of a focus point into ...
Differential Blending for Expressive Sketch-Based Posing
(ACM SIGGRAPH / Eurographics Association, 2013)
Generating highly expressive and caricatured poses can be difficult in 3D computer animation because artists must interact with characters indirectly through complex character rigs. Furthermore, since caricatured poses ...
