La qualification des ambiances sonores urbaines

Un système multi-agent pour la simulation des dynamiques urbaines

Simulating the evolution of cities suggests the ability to understand and model the laws governing urban dynamics. The approach presented in this paper uses a multi-agent system to model the self-organising properties of urban systems and aims at providing a tool to study the evolutions of the modelled system. The proposed multi-agent system is a hierarchy of topographic agents (e.g. buildings,...

Première étape vers une navigation référentielle par l'image pour l'assistance à la conception des ambiances lumineuses

In the first design stage, image reference plays a double role of means of formulation and resolution of problems. In our approach, we consider image reference as a support of creation activity to generate ideas and we propose a tool for navigation in references by image in order to assist daylight ambience design. Within this paper, we present, in a first part, the semantic indexation method t...

An acoustic ambience study by immersive sound recognition

For many years, architectural and urban ambiences have been the main study subject of our laboratory, dealing with the urban built shape interactions. Classical results are predictive numerical models, which provide parameters related to the environment physical factors. Through interaction with environmental parameters such as sound, the human being position through its perception of environme...

Construction, manipulation et visualisation de processus sonores dans des environnements virtuels immersifs pour la performance musicale

The work presented in this thesis belongs to the computer music field as well as to the virtual reality field. First, we describe the advantages of immersive virtual environments and of 3D graphical interaction for multiprocess instruments and particularly for the hierarchical live-looping, a new instrument model that we define. We then suggest solutions to visualize and manipulate sound proces...
