Semantics-based representation of virtual environments

Daniel Thalmann, Frédéric Vexo

In this paper we present an object representation based on the semantics and functionality of interactive digital items - virtual objects - within a virtual environment (VE). We consider every object participating in a VE application not only as a 3D shape ...

Multi-finger haptic rendering of deformable objects

Daniel Thalmann, Ronan Boulic, Sofiane Sarni, Anderson Maciel, Olivier Buchwalder

The present paper describes the integration of a multi-finger haptic device with deformable objects in an interactive environment. Repulsive forces are synthesized and rendered independently for each finger of a user wearing a Cybergrasp force-feedback glo ...

Creating cyberworlds: experiences in computer science education

Daniel Thalmann, Frédéric Vexo

This article shows that the creation of cyberworlds (interactive virtual environments) can be an excellent educational tool covering a wide range of computer science and engineering disciplines. We present the experiences gathered during more than one seme ...

Virtual humans for virtual reality and augmented reality

Daniel Thalmann

The tutorial will explain the techniques for integrating virtual humans into virtual and real environments. It will first present the concept of avatars and autonomous virtual actors and the main techniques to create and animate them (body and face). It wi ...

The virtual human as a multimodal interface

Daniel Thalmann

This paper discusses the main issues for creating interactive virtual environments with virtual humans emphasizing the following aspects: creation of virtual humans, gestures, interaction with objects, multimodal communication ...

Towards interactive real-time crowd behavior simulation

Daniel Thalmann, Branislav Ulicny

While virtual crowds are becoming common in non-real-time applications, the real-time domain is still relatively unexplored. In this paper we discuss the challenges involved in creating such simulations, especially the need to efficiently manage variety. W ...

Sharing attractions on the Net with VPark

Daniel Thalmann, Joaquim Esmerado

We present a networked virtual environment (NVE) system and an attraction building system based on Windows NT that enables users to introduce their own scenario-based applications into a shared virtual environment. Our goal was to develop and integrate sev ...

Simulating virtual humans in networked virtual environments

Daniel Thalmann

In the past decade, networked virtual environments (NVEs) have been an increasingly active area of research, with the first commercial systems emerging recently. Graphical and behavioral representation of users within such systems is a particularly importa ...

Path finding for human motion in virtual environments

Daniel Thalmann

This paper presents an efficient and robust technique for generating global motion paths for a human model in virtual environments. Initially, a scene is discretized using raster hardware to generate an environment map. An obstacle-free cell path sub-optim ...

A paradigm for controlling virtual humans in urban environment simulations

Daniel Thalmann, Ronan Boulic

Presents a new architecture for simulating virtual humans in complex urban environments. The approach is based on the integration of six modules. Four key modules are used in order to manage environmental data, simulate human crowds, control interactions b ...
