Motion capture systems usually work in conjunction with complex 3D applications, such as 3D Studio Max by Kinetix or Maya by Alias/Wavefront. Once models have been created in these applications, motion capture systems provide the necessary data input to an ...
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 ...
We present a networked virtual environment (NVE) system and an attraction building system based on Windows NT that enables users to introduce their own scenario-based applications into a shared virtual environment. Our goal was to develop and integrate sev ...
The following topics are dealt with: motion capture and 3D reconstruction; parametric motion and retargeting; muscles and deformation models; facial animation and communication; and high-level behaviors and autonomous agents ...
In this paper, we extend our previous work (Proc. Computer Animation and Simulation, pp. 125-135, Aug. 2000) and propose a muscle model that is suitable for computer graphics based on physiological and anatomical considerations. Muscle motion and deformati ...
In virtual human modeling, the shoulder is usually composed of clavicular, scapular and arm segments related by rotational joints. Although the model is improved, the realistic animation of the shoulder is hardly achieved. This is due to the fact that it i ...
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 ...
Presents an integration framework for heterogeneous motion generators. The objective is to outline issues that are currently easily solved in the professional post-processing systems used in film and game production but which cannot be transposed “as ...
Most automatic facial expression analysis systems try to analyze emotion categories. However, psychologists argue that there is no straight forward way to classify emotions from facial expressions. Instead, they propose FACS (Facial Action Coding System), ...
Current virtual reality technologies provide many ways to interact with virtual humans. Most of those techniques, however, are limited to synthetic elements and require cumbersome sensors. We have combined a real-time simulation and rendering platform with ...
