Motion capture has been adopted for the production of highly realistic movements, as well as for the clinical analysis of pathological motion. In both cases, a skeleton model has to be identified to derive the joint motion. The optical technology has gaine ...
In this paper we show how the mass properties of an articulated body, such as its center of mass and its moments of inertia, may be manipulated like any conventional end effector, with well-known iterative, numerical techniques. Within our interactive simu ...

Optical motion capture provides an impressive ability to replicate gestures. However, even with a highly professional system there are many instances where crucial markers are occluded or when the algorithm confuses the trajectory of one marker with that o ...
Rendering and animating in real-time a multitude of articulated characters presents a real challenge, and few hardware systems are up to the task. Up to now, little research has been conducted to tackle the issue of real-time rendering of numerous virtual ...
In combination with the rapid technical improvements of computers, building large virtual scenes has become a popular field in computer graphics. Often, within a real reconstructed city, a building that has disappeared, or a virtual town, virtual humans po ...
We present a new method for solving the motion retargeting problem, by using an intermediate skeleton. This allows us to convert movements between hierarchically and geometrically different characters. An inverse kinematics engine is then used to enforce C ...
Most of today's virtual environments are populated with some kind of autonomous life-like agents. Such agents follow a preprogrammed sequence of behaviours that excludes the user as a participating entity in the virtual society. In order to make inhabited ...
Motion capture techniques are rarely based on orientation measurements for two main reasons: (1) optical motion capture systems are designed for tracking object position rather than their orientation (which can be deduced from several trackers), (2) known ...
We outline the creation of an Informed Environment, dedicated to urban life simulation. We propose methods and tools for creating and providing the information necessary for animating virtual humans in a city using an Informed Environment. The Informed Env ...
Presents a new architecture for simulating virtual humans in complex urban environments. The approach is based on the integration of six modules. Four key modules are used in order to manage environmental data, simulate human crowds, control interactions b ...
