The democratization of Computer Arts and Computer Music has, due to dematerialization(virtualization) con-sequence of digital technologies, considerably widenedthe boundaries of creativity. As we are now entering a second phase that has been labeled “post-digital”, we are calledto reconcile this openness with notions such as embodiment, presence, e...
Conference Paper
This work focuses modelling and simulation of physics-based topological discontinuities in deformable objects, as they appear in fracturing, tearing or cracking phenomena. It introduces a new methodology, called “Splitting MAT”, which integrates into masses-interactions modelling. This methodology enables modelling topological discontinuities not o...
Conference Paper
This work introduces a new modeling/simulation pipeline for handling topological discontinuities as they appear in fracturing, tearing or cracking phenomena. This pipeline combines, in a cascade (1) physics-based particle modeling, which enables a wide variety of temporal phenomena, including physics state changes; (2) explicit topological modeling...

Conference Paper
Animation of topological transformations, such as fractures, cracks, tears, crumbles or fragmentations, is a new challenge in Computer Graphics and Animation. We propose a new way to model and animate topological changes, allowing the programmer to design any type of topological changes and animation mapping. This model is based on organizing the c...
Conference Paper
We present GENESIS-RT, a Virtual Reality platform conceived for musical creation. It allows the user to (1) interactively create physically-based musical instruments and sounding objects, and (2) play them in real time in a multisensory fashion, by ways of haptics, 3D visualisation during playing, and sound. The design of this platform aims for ful...
Conference Paper
Particle-based models produce various, flexible and optimized animations. Intrinsically, they are neither based on a boundary representation nor on volumetric objet meshed representations. Thus, they raise rendering issues since they do not contain enough geometrical information and do not even provide an underlying spatial topology. Consequently,...
Conference Paper
Full-text available
In this work, we carried out psychocognitive experiments about the human cognitive behavior faced to a new generation of virtual animations. These animations are based on motion synthesized by means of physical modeling, and synthetic shapes mapped on the so produced movements. The novelty of these animations is that we associated two complementary...
Conference Paper
Full-text available
Les modèles particulaires permettent de produire des animations riches et variées. Ils sont particulièrement adaptés à certains effets d’animation. Mais intrinsèquement, ils ne sont pas basés sur des représentations surfaciques ou volumiques d’objets. Ainsi, visualiser le mouvement qu’ils décrivent peut poser problème car ils ne contiennent souvent...
Conference Paper
In order to better understand perceptual and cognitive features of shapes and motions associations, we first create synthetic animation composed of realistic motions modeled by physical modeling mapped on abstract shapes. Second, we propose such paradoxical and surprising animations to subject's observations and we analyze them by qualitative analy...
Conference Paper
Full-text available
In this work, we designed virtual animations by generating motion synthesis by means of physical modeling and synthesized shapes mapped on some produced movements. The novelty is that we associated two complementary kinds of figures: on one hand, the movement, as it is built using physical models, which presents realistic and coherent dynamics, and...

Article
This work is grounded on the idea that physical and topological properties are complementary features in visual objects and their transformations. Indeed, physical properties delimit the quality of the dynamics whereas topological properties focus on the spatial organization. In this paper, we propose a new cooperation between mass-interaction mode...

This paper is focused on the question of simulation and visualiza- tion of 3D gel and paste dynamic effects. In a first part, we introduce a 3D physically based particle (or mass-interaction) model, with a small number of masses and few powerful interaction parameters, which is able to generate the dynamic features of both gels and pastes. This mod...

Full-text available
The nanoworld is invaded by human technologies but remains foreign to our perception and action. Discussions about “nanos” in the society ask for knowledge dissemination in population. Simultaneously, scientists in biology, chemistry... need tools to directly manipulate single nano-object. Both aspects can be now addressed by coupling real time mul...
Conference Paper
« Somnambule » is a global instrument which produces sound and picture, generated by a gesture - more precisly the pianistic gesture. The sound has its source in two different worlds : the real world for the sound of piano, and the virtual world for the synthetic sounds. The video derives directly from the dynamic of the pianistic gesture, where a...

We explore how an ‘ergotic gesture-sound situation’ is a genuine way to improve the playability, believability and presence of virtual musical instruments. An ergotic gesture-sound situation is a situation where the instrumental gesture and the sound produced are intimately energetically linked. We perform two sets of experiments: the first aims at...

Full-text available
For hand–object interaction in real situations the interplay between the local tactile interaction and force interaction seems to be very important. In current haptic interfaces, however, two different trends are present: force feedback devices which offer a permanent invariable grip and a resultant force, and tactile devices, which offer variable...

Numerous studies have been performed on the human perception of object's weight, elasticity or viscosity. Most of them were however based on discrimination tasks, and used or simulated very simple objects from haptic and visual information. We found that observers could make judgements on elasticity in an orderly way, and that all of the different...

Several studies have investigated the robustness of the sound-action perception to auditory delay, and the effects of delay on performance in tapping gesture. In this paper we propose a complementary approach, by modifying the stiffness of the tapped object. Participants had to perform synchronous tapping along with a metronome reference, using a o...

The presentation and the evaluation of an educational tool based on a haptic interface used to teach physical phenomena at a nanometer scale are the central objectives of the present work. This haptic interface has also allowed characterising non-conventional samples illustrated through an experience when students shake the Drosophilae leg.
Conference Paper
The link from action to sound is under-explored in virtual realities. The article categorizes the action-sound relations, proposing the term "ergotic" to refer to the case when there is a mechanical interaction between the subject and the sound source. Force-feedback devices and physically based models are indeed required for implementing virtual e...
Conference Paper
As quoted in the philosophy of contemporary dance: >, a lot of emphasis is put currently on generating computing dance movement by dynamic and energy, which is totally different from producing movement by kinematical based gestures in sequence. We argue that it is an ideal interactive media to connect computer and choreographer.In this paper, we pr...

As quoting in the philosophy of free dance: «Understanding the directions for a Free Dance performer stems mainly from the qualities and energy of the movement rather from spatial criteria», we advocate that dance movement is not only to perform a desired motion but also to feel and to transmit "sensation (expression)" by body and energy. Dynamic m...
