Linear Local Models for Monocular Reconstruction of Deformable Surfaces

Recovering the 3D shape of a nonrigid surface from a single viewpoint is known to be both ambiguous and challenging. Resolving the ambiguities typically requires prior knowledge about the most likely deformations that the surface may undergo. It often take ...

Realtime Performance-Based Facial Animation

Mark Pauly, Hao Li, Sofien Bouaziz

This paper presents a system for performance-based character animation that enables any user to control the facial expressions of a digital avatar in realtime. The user is recorded in a natural environment using a non-intrusive, commercially available 3D s ...

Ergonomic Simulation Revisited Using Parametric Virtual Humans in the Biomechanical Framework

Hareesh Puthiya Veettil

The conventional CAD/CAM approach to design does not show the essential spatial relationships between user and product that are crucial for intuitive design analysis. As populations age and the home appliance market stagnates, Universal Design principles i ...

Parametric free-form shape design with PDE models and reduced basis method

Gianluigi Rozza, Toni Mikael Lassila

We present a coupling of the reduced basis methods and free-form deformations for shape optimization and design of systems modelled by elliptic PDEs. The free-form deformations give a parameterization of the shape that is independent of the mesh, the initi ...

Understanding cave genesis along favourable bedding planes. The role of the primary rock permeability

Laurent Tacher, Marco Filipponi, Pierre-Yves Jeannin

Recent studies on the complex 3D geometry of large cave systems around the World allowed us to get statistical evidence of the inception horizon hypothesis. It clearly confirmed the idea that the development of karst conduits under phreatic conditions is s ...

Modélisation géométrique itérative sous contraintes

Gilles Gouaty

Iterative models are widely used today in CAD. They allow, with a limited number of parameters, to represent relatively complex forms through a subdivision algorithm. There is a wide variety of such models (Catmull-Clark, Doo-Sabin, L-Systems...). Most ite ...

Modeling stochasticity and robustness in gene regulatory networks

Giovanni De Micheli, Abhishek Garg, Ioannis Xenarios

Motivation: Understanding gene regulation in biological processes and modeling the robustness of underlying regulatory networks is an important problem that is currently being addressed by computational systems biologists. Lately, there has been a renewed ...

Visualization and analysis of SPH data

Pierre Maruzewski

Advances in graphics hardware in recent years have led not only to a huge growth in the speed at which 3D data can be rendered, but also to a marked change in the way in which different data types can be displayed. In particular, point based rendering tech ...

A Fast Method for Finding Range of Motion in the Human Joints

Daniel Thalmann, Ronan Boulic, Ehsan Arbabi

Finding the range of motion for the human joints is a popular method for diagnosing joint diseases. By current technology, it is more trustable and easier to find the range of motion by employing computer based models of the human tissues. In this paper we ...

VARIABLE-ANGLE 3-DIMENSIONAL EXCHANGE NUCLEAR-MAGNETIC-RESONANCE SPECTROSCOPY FOR THE STUDY OF MOLECULAR-MOTION IN COMPLEX SOLIDS

David Lyndon Emsley

Although molecular motions are responsible for many of the macroscopic properties observed in solids, especially in polymers, methods for studying these processes in all but the simplest systems are scarce. In the present study we introduce a three-dimensi ...
