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)
The exchange of avatars, i.e. the actual fact of changing once avatar with another one, is a promising trend in multi-actor virtual environments. It provides new opportunities for users, such as controlling a different avatar for a specific action, retrieving knowledge belonging to a particular avatar, solving conflicts and deadlocks situations or even(More)
Virtual agents are a real asset in collaborative virtual environment for training (CVET) as they can replace missing team members. Collaboration between such agents and users, however, is generally limited. We present here a whole integrated model of CVET focusing on the abstraction of the real or virtual nature of the actor to define a homogenous(More)
This paper presents #FIVE (Framework for Interactive Virtual Environments), a framework for the development of interactive and collaborative virtual environments. #FIVE has been developed to answer the need for an easier and a faster conception and development of virtual reality applications. It has been designed with a constant focus on re-usability with(More)
We present a 3D container model that enables the compositing of 3D file formats. It allows not only to compose 3D scenes made of several 3D files of different types but also to combine their functionalities and to make them interact together in the rendering window. This model, called 3DFC for 3D File Container, relies on the Scene Graph Adapter (SGA)(More)
In this paper we present #SEVEN, a sensor effector model that enables the execution of complex scenarios for driving Virtual Reality applications. #SEVEN is based on an enhanced Petri net model which is able to describe and solve intricate event sequences. Our model also proposes several useful features for the design of collaborative scenarios for(More)
This paper presents the use of Virtual Reality (VR) for movie actors rehearsal of VFX-enhanced scenes. The impediment behind VFX scenes is that actors must be filmed in front of monochromatic green or blue screens with hardly any cue to the digital scenery that is supposed to surround them. The problem is worsens when the scene includes interaction with(More)
