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 ...

Defining behaviors for autonomous agents based on local perception and smart objects

Daniel Thalmann

An integrated framework is proposed in which local perception and close manipulation skills are used in conjunction with a high-level behavioral interface based on a "smart object" paradigm as support for virtual agents to perform autonomous tasks. In our ...

Specifying MPEG-4 body behaviors

Daniel Thalmann, Anthony Guye-Vuillème

The MPEG-4 standard specifies a set of low-level animation parameters for body animation, but does not provide any high-level functionality for the control of avatars or embodied agents. In this paper we discuss the required features for a script format al ...

Deformable Avatars

Daniel Thalmann

The following topics are dealt with: motion capture and 3D reconstruction; parametric motion and retargeting; muscles and deformation models; facial animation and communication; and high-level behaviors and autonomous agents ...

ACE: a platform for the real time simulation of virtual human agents

Daniel Thalmann, Jean-Sébastien Monzani

The paper describes a system platform for virtual human agent simulations that is able to coherently manage the shared virtual environment. Our “agent common environment” (ACE) provides built-in commands for perception and for acting, while the ...

Verbal communication using approximate sound propagation to design an inter-agents communication language

Daniel Thalmann, Jean-Sébastien Monzani

We present a method for generating conversations between human-like agents by proposing specific parameters for inter-agents messages with an approximation of virtual sound propagation. We are then be able to simulate appropriate human-like behaviours auto ...

Nonverbal communication interface for collaborative virtual environments

Daniel Thalmann, Anthony Guye-Vuillème

Nonverbal communication is an important aspect of real-life face-to-face interaction and one of the most efficient ways to convey emotions, therefore users should be provided the means to replicate it in the virtual world. Because articulated embodiments a ...

Anyone for tennis?

Daniel Thalmann, Amaury Aubel

The authors present a virtual tennis game. They describe the creation and modeling of the virtual humans and body deformations, also showing the real-time animation and rendering aspects of the avatars. They focus on the animation of the virtual tennis bal ...

Conferring human action recognition skills to life-like agents

Daniel Thalmann, Ronan Boulic

Most of today's virtual environments are populated with some kind of autonomous life-like agents. Such agents follow a preprogrammed sequence of behaviours that excludes the user as a participating entity in the virtual society. In order to make inhabited ...

Virtual hand interactions with 3D world

Daniel Thalmann, Zhouji Huang

Interactions between a virtual actor and its virtual environment involve many aspects. An important one is hand interactions. In a virtual scene depicting everyday life, the actor will need to grasp and hold objects, in such a way that both skeleton motion ...
