November 2016 Concurrency and Computation: Practice & Experience: Volume 28 Issue 16, November 2016
Publisher: John Wiley and Sons Ltd.
Citation Count: 1

This paper describes the use of domain decomposition methods for accelerating wave physics simulation. Numerical wave-based methods provide more accurate simulation than geometrical methods, but at a higher computation cost as well. In the context of virtual reality, the quality of the results is estimated according to human perception, what ...

This paper covers the time consuming issues intrinsic to physically-based image rendering algorithms. First, glass materials optical properties were measured on samples of real glasses and other objects materials inside an hotel room were characterized by deducing spectral data from multiple trichromatic images. We then present the rendering model and ...

September 2014 A Roadmap in Digital Heritage Preservation on 3D Research Challenges in Cultural Heritage - Volume 8355
Publisher: Springer-Verlag New York, Inc.
Citation Count: 1

3D data acquisition and 3D virtual and physical reproductions are shortly described within the framework of our experiments with museum artefacts. Our experience in the cultural heritage field illustrates a lot of problems encountered and the solutions we brought. From this short analysis, a perspective for the next 10 or ...

In this paper, we use an original ray-tracing domain decomposition method to address image rendering of naturally lighted scenes. This new method allows to particularly analyze rendering problems on parallel architectures, in the case of interactions between light-rays and glass material. Numerical experiments, for medieval glass rendering within the church ...

As buildings from ancient times wither away or are transformed or destroyed, it becomes increasingly difficult to figure what it looked like back then. Virtual reality is a great tool to handle this role, although it often implies a three-dimensional model of a building disconnected from the remains. In this ...

In this paper, an original beam-tracing domain decomposition method is proposed for church acoustics. This new method allows to analyze large-scale acoustics problems in a reasonnable time on parallel architectures. Numerical experiments, for sound holography within the church of the Royaumont abbey, illustrate the performance of the proposed beam-tracing domain ...

October 2012 EuroMed'12: Proceedings of the 4th international conference on Progress in Cultural Heritage Preservation
Publisher: Springer-Verlag
Citation Count: 1

Fundamental optical properties of materials are described by intrinsic parameters that can be concentrated in only one notion: the components of the complex dielectric tensor. Such a notion is relevant in any cases and we shall give examples of applications in the cultural heritage field. Modern glasses characterization and ancient ...

The Idalion Tablet, an antique bronze (480-470 BC) found around 1850 in the antique city of Idalion in Cyprus is the main purpose of the presented interdiciplinary work. The tablet is the property of the Bibliothèque Nationale de France (BNF) since 1862, and is absent from collections of the Idalion ...

September 2010 VAST'10: Proceedings of the 11th International conference on Virtual Reality, Archaeology and Cultural Heritage
Publisher: Eurographics Association
Citation Count: 1

Lighting either natural or not in the european medieval architecture (roman period) is studied and simulated around a special and famous example. "Notre-Dame de Paris" cathedral and its polychromy are studied for many years and, today the remains of polychromy are very reduced. This prestigious monument is then a unique ...
