Populating Ancient Pompeii with Crowds of Virtual Romans

Daniel Thalmann, Jonathan Maim, Barbara Yersin

Pompeii was a Roman city, destroyed and completely buried during an eruption of the volcano Mount Vesuvius. We have revived its past by creating a 3D model of its previous appearance and populated it with crowds of Virtual Romans. In this paper, we detail ...

An action selection architecture for autonomous virtual humans in persistent worlds

Etienne De Sevin

Nowadays, virtual humans such as non-player characters in computer games need to have a strong autonomy in order to live their own life in persistent virtual worlds. When designing autonomous virtual humans, the action selection problem needs to be conside ...

Merging Cellular Automata for Simulating Surface Effects

Stéphane Gobron

This paper describes a model of three-dimensional cellular automata allowing to simulate different phenomena in the fields of computer graphics or image processing. Our method allows to combine them together in order to produce complex effects such as auto ...

Organic shape modeling through haptic devices

Daniel Thalmann, Frédéric Vexo, Renaud Ott

This paper presents a sketching system for 3D organic shapes modeling and animation using virtual reality devices. On the hardware side, it is based on the Haptic Workstation™ which conveys force feedback on the user arms (upper body limbs), and a head mou ...

Real-time navigating crowds: Scalable simulation and rendering

Daniel Thalmann, Jonathan Maim, Barbara Yersin

This paper introduces a framework for real-time simulation and rendering of crowds navigating in a virtual environment. The solution first consists in a specific environment preprocessing technique giving rise to navigation graphs, which are then used by t ...

Implicit Meshes for Surface Reconstruction

Pascal Fua, Slobodan Ilic

Deformable 3--D models are used extensively in Computer Graphics and Computer Vision for Visualization, Animation and Modeling. They can be represented either as traditional explicit surfaces, such as triangulated meshes, or as implicit surfaces. Explicit ...

A multitasking and data-driven architecture for multi-agents simulations

Sébastien Schertenleib

The expansion of 3D real-time simulations (3DRTS) into millions of homes together with the technical progress of computers hardware force to approach software developments for 3DRTS from different perspectives. From an historical standpoint, 3DRTS started ...

Theoretical treatment and computer simulation of microelectrode arrays

Nico de Rooij

New relations for and interrelations between the current responses of different microelectrode arrays are presented. Interdigitated microelectrode arrays (IDAs: alternating cathodes and anodes) and uniform microband electrode arrays (MEAs: only cathodes or ...

Omnidirectional views selection for scene representation

Pascal Frossard, Ivana Tosic

This paper proposes a new method for the selection of sets of omnidirectional views, which contribute together to the efficient representation of a 3d scene. When the 3d surface is modelled as a function on a unit sphere, the view selection problem is most ...

Standardized Virtual Reality, are we there yet ?

Daniel Thalmann, Frédéric Vexo

Despite its history of several decades and impressive achievements, developing a VR application is still a complex task. Setting-up a Virtual Environment requires choosing a suitable combination of elements from a large amount of technologies, software fra ...
