Le, Moulec Gwendal. "Synthèse d'applications de réalité virtuelle à partir de modèles". Thesis, Rennes, INSA, 2018. http://www.theses.fr/2018ISAR0010/document.
Development practices in Virtual Reality (VR) are not optimized. for example, each company uses its own methods. The goal of this PhD thesis is to automatize development and evaluation of VR software with the use of Model-Driven Engineering (MDE) technics. The existing approaches in VR do not take advantage of software commonalities. Those lacks of reuse and abstraction are known problems in MDE, which proposes the Soflware Product Line (SPL) concept to automatize the production of software belonging to the same family, by reusing common components. However, this approach is not adapted to software based on a scenario, like inVR.We propose two frameworks that respectively address the lacks in MDE and VR : SOSPL (scenario-oriented software product line) and VRSPL (VR SPL). SOSPL is based on a scenario model that handles a software variability model (feature model , FM). Each scenario step matches a configuration of the FM. VRSPL is based on SOSPL. The scenario manages virtual objects manipulation, the objects being generated automatically from a model. We implemented these frameworks inside tools that have been tried on exemples and evaluated by their target users. The results promote the use of these frameworks for producing scenario-based software
Verron, Charles. "Synthèse immersive de sons d'environnement". Aix-Marseille 1, 2010. http://theses.univ-amu.fr.lama.univ-amu.fr/2010AIX11009.pdf.
Most of the existing tools for producing sounds in virtual environments are based on wavetables : sounds are pre-recorded and triggered in real time according to the actions of the user in the virtual world. Spatialization techniques are usually integrated in a second stage, for simulating reverberation and spatial properties of sound sources, such as position, directivity and spatial extension. In this thesis we propose an original approach to synthesis and spatialization of environmental sounds. We design a real-time synthesizer that produces various environmental sources (like rain, wind, fire, waves, impacts. . . ), provides interactive controls based on “high-level” parameters, and allows manipulating the sources in a 3D virtual space. After reviewing the existing synthesis approaches for environmental sounds, we propose a generic model based on additive synthesis and on a set of five parametric sonic structures called “atoms”. An adequate combination of these atoms allows the creation of sources associated with the three categories of environmental sources : vibrating solids, aerodynamics and liquids. The synthesizer engine combines efficiently synthesis and spatialization modules at the prime level of sound generation. We use the efficient implementation of additive synthesis by inverse fast Fourier transform, and propose an adapted set of parameters. The 3D audio rendering is compatible with standard audio formats (multichannel, ambisonics, binaural) and can be achieved on arbitrary loudspeaker configurations or over headphones. We also present an alternative synthesis method based on a “subband” formalism for synthesizing noisy signals that contain at the same time short transients and narrow spectral components (like impacts or fire sounds). High-level controls are specified for manipulating the synthesizer intuitively, via physical properties such as “the speed of the wind” or “the intensity of the fire”. We also propose a spatial extension effect, validated by a formal listening test, for simulating efficiently naturally extended sound sources like rain or waves. Combined controls of timbre and spatial properties of sources allow creating intuitively complex and immersive sound scenes

A majority of 3d films and computer graphics respect a realistic aesthetic. On one hand, I will analyse why such totally made images initiate a film or reality and on the other hand, I will try to offer alternativity in order to create an other aesthetic, not being realistic. Softwares need numerous scientific formulas, therefore the author, while manipuling it, will be the main actor to change the situation. This is the main point. Realism exists in every 3d application, such as research, tv, cinema, fiction, school and even often in creation. A few artists managed to escape from realism, i. E. : Joan Stavely, Tamas Waliczky or Michel Bret. Each has its own way of working but they all aim at the same: not to reach realistic simulation. I agree on this point and illustrate my thinking, I made three 3d films with more sensitivity than technical challenge. It is possible to avoid the trap of realism. Indeed, by manipulating and divert the software, one can obtain different 3d computer graphics. Step by step, a new approach to handle and to develop tools apears, and thanks to this, authors can create films other than realistic.

Nowadays, computer generated images are very present in our everyday life. Realism of these images is increasing, surprising and it isn’t often easy to distinguish the reality of the virtuality, this reality made by all the complexity of the natural phenomena which surround us. Water is one of these phenomena among which the variety and the dynamic comportment produce complex representation. We are interested in this thesis in its most area shape, that of the oceans, which are a part integral of our landscapes. At first, we study the methods allowing the simulation and rendering of the ocean in the physical domain and in computer graphics. In the second chapter, we propose a new rendering method unified allowing a faster visualization of ocean surface and allowing to approximate scattering and sub-scattering exchanges of light, foam and glare effects. In the chapter 3, we are interested to breaking waves by proposing a new physical based adaptive approach allowing to reproduce this phenomenon and to reduce time of calculations imposed by the resolution of equations of the fluid mechanics in 3D. In the fourth chapter, we extend this model by proposing a hierarchical approach allowing a stronger acceleration of the process of resolution and to obtain a simulation close to interactivity

It computer graphics is analysed within a historical background of a pictorial tradition, and not exclusively under the traditional perspective view-point, it also can be thorugh other artistic evolutions, so that it sounded out as the outcome of the illusionnist representation history, whose stakes computer graphics joins and brings foreward. Beyond a possible comparison of these shapes to varied pictorial aesthetics, computer graphics creation tools are resolutely new. They sometimes materialize into a computer. But they can remaion conceptual, asd an algorithm, the nature of such a represented object comes completely transformed. By using those numerous representations of a same object, computer graphics is brought into the world of motion, and thus, through virtual realities, it can immensde as well individually people, as virtual communities socially do it. In fact, the improvement in these representation forms can lead to confusion with analogical image - a reality trace - and can supplant reality itself
