Composite control of physically simulated characters
Uldarico Muico, Jovan Popović, Zoran Popović
Article No.: 16
A physics-based control system that tracks a single motion trajectory produces high-quality animations, but does not recover from large disturbances that require deviating from this tracked trajectory. In order to enhance the responsiveness of...
We propose a generalized approach to decoupling shading from visibility sampling in graphics pipelines, which we call decoupled sampling. Decoupled sampling enables stochastic supersampling of motion and defocus blur at reduced shading...
Motion reconstruction using sparse accelerometer data
Jochen Tautges, Arno Zinke, Björn Krüger, Jan Baumann, Andreas Weber, Thomas Helten, Meinard Müller, Hans-Peter Seidel, Bernd Eberhardt
Article No.: 18
The development of methods and tools for the generation of visually appealing motion sequences using prerecorded motion capture data has become an important research area in computer animation. In particular, data-driven approaches have been used...
Physically valid statistical models for human motion generation
Xiaolin Wei, Jianyuan Min, Jinxiang Chai
Article No.: 19
This article shows how statistical motion priors can be combined seamlessly with physical constraints for human motion modeling and generation. The key idea of the approach is to learn a nonlinear probabilistic force field function from...
The simulation of weathered appearance is essential in the realistic modeling of urban environments. A representative and particularly difficult effect to produce on a large scale is the effect of fluid flow. Changes in appearance due to flow are...
In this article we derive an equation for the velocity of an arbitrary time-evolving implicit surface. Strictly speaking, only the normal component of the velocity is unambiguously defined. This is because an implicit surface does not have a...
We present a method for restoring antialiased edges that are damaged by certain types of nonlinear image filters. This problem arises with many common operations such as intensity thresholding, tone mapping, gamma correction, histogram...
Space-time planning with parameterized locomotion controllers
Sergey Levine, Yongjoon Lee, Vladlen Koltun, Zoran Popović
Article No.: 23
We present a technique for efficiently synthesizing animations for characters traversing complex dynamic environments. Our method uses parameterized locomotion controllers that correspond to specific motion skills, such as jumping or obstacle...
Highlighted depth-of-field photography: Shining light on focus
Jaewon Kim, Roarke Horstmeyer, Ig-Jae Kim, Ramesh Raskar
Article No.: 24
We present a photographic method to enhance intensity differences between objects at varying distances from the focal plane. By combining a unique capture procedure with simple image processing techniques, the detected brightness of an object is...
Progressive photon mapping: A probabilistic approach
Claude Knaus, Matthias Zwicker
Article No.: 25
In this article we present a novel formulation of progressive photon mapping. Similar to the original progressive photon mapping algorithm, our approach is capable of computing global illumination solutions without bias in the limit, and it uses...
Global registration of dynamic range scans for articulated model reconstruction
Will Chang, Matthias Zwicker
Article No.: 26
We present the articulated global registration algorithm to reconstruct articulated 3D models from dynamic range scan sequences. This new algorithm aligns multiple range scans simultaneously to reconstruct a full 3D model from the geometry of...
