Real-time motion planning, navigation, and behavior for large crowds of virtual humans

Simulating crowds in real time is a challenging problem that touches many different aspects of Computer Graphics: rendering, animation, path planning, behavior, etc. Our work has mainly focused on two particular aspects of real-time crowds: motion planning ...

Gaze Behaviors for Virtual Crowd Characters

Daniel Thalmann, Barbara Yersin, Jonathan Maim, Helena Stephanie Grillon Le Gallennec

Nowadays, crowds of virtual characters are used in many domains such as neurosciences, psychology, and computer sciences. Since as human beings, we are natural experts in human being representation and movement, it makes it that much harder to correctly mo ...

Crowd Patches: Populating Large-Scale Virtual Environments for Real-Time Applications

Daniel Thalmann, Barbara Yersin, Jonathan Maim

Populating virtual environments (VEs) with large crowds is a subject that has been tackled for several years. Solutions have been proposed to offer realistic trajectories as well as interactivity, but limitations remain on the environment dimensions with r ...

Unique Character Instances for Crowds

Daniel Thalmann, Barbara Yersin, Jonathan Maim

Real-time crowd simulations are realistic only if each human instance looks unique. A proposed solution varies the shape of human instances by attaching accessories. It also modifies the instances' appearance with a generic technique based on segmentation ...

Challenges in Crowd Simulation

Daniel Thalmann, Barbara Yersin, Jonathan Maim, Helena Stephanie Grillon Le Gallennec

The purpose of this paper is to identify the problems to solve in order to simulate real-time crowds in a Virtual Environment. We try to classify these problems and study how they have been addressed until now by the research community and our Lab in parti ...

Populating Ancient Pompeii with Crowds of Virtual Romans

Daniel Thalmann, Barbara Yersin, Jonathan Maim

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 ...

Real-Time Scalable Motion Planning for Crowds

Daniel Thalmann, Barbara Yersin, Jonathan Maim, Fiorenzo Morini

Real-time crowd motion planning requires fast, realistic methods for path planning as well as obstacle avoidance. The difﬁculty to ﬁnd a satisfying trade-off between efﬁciency and believability is particularly challenging, and prior techniques tend to focu ...

Real-time navigating crowds: Scalable simulation and rendering

Daniel Thalmann, Barbara Yersin, Jonathan Maim

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 ...
