We present a generic architecture which enables the loading of several 3D formats in most 3D application engines. The purpose of this work is to solve the interoperability issue among 3D formats raised by the multiplicity of formats. We propose a programming interface, the Scene Graph Adapter, that allows mixing several 3D formats in a single application(More)
This demonstration introduces new ways and approaches for exploring 3D scientific datasets obtained by numerical simulation. Three main points will be addressed, including compression methods, collaborative virtual environments and features enabling the mix, in the same shared virtual scene, of results given by two different post-processing engines(More)
We present in this paper a generic animation and simulation platform which integrates the different animation models: descriptive, generative and behavioural models. The integration of these models in the same platform allows to offer to each dynamic entity a more realistic and a richer environment, and thereby to increase possible interactions between an(More)
Collaborative Virtual Environments (CVE) enable users to collaborate and interact together by sharing a common virtual environment. Ensuring the global consistency of a virtual environment is very important to provide efficient collaboration between users. However, users sharing a CVE may be scattered over different physical locations, so CVE systems have(More)
Plasticity of 3D user interfaces refers to their capabilities to automatically fit to a set of hardware and environmental constraints. This area of research has already been deeply explored in the domain of traditional 2D user interfaces. Besides, during the last decade, interest in 3D user interfaces has grown. Designers find with 3D user interfaces new(More)

Consistency of the virtual environment is very important to provide an efficient collaboration between users.

This paper describes a novel 3D interaction technique called the “SkeweR”, dedicated to the 2-user collaborative manipulation of objects in virtual environments. This technique enables two users to move simultaneously the same virtual object in 3D. For this aim, each user manipulates the object by one crushing point, like handling the extremity of a skewer.(More)
Most Virtual Reality (VR) systems must consider the users’ physical environment to immerse these users in a virtual world and to make them aware of their interaction capabilities. However, no consensus has been found in the existing VR systems to embed the real environment into the virtual one: each system meets its particular requirements according to the(More)
