Generating, animating, and rendering varied individuals for real-time crowds

To simulate realistic crowds of virtual humans in real time, three main requirements need satisfaction. First of all, quantity, i.e., the ability to simulate thousands of characters. Secondly, quality, because each virtual human composing a crowd needs to ...

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 ...

Reviving the Roman Odeon of Aphrodisias: Dynamic Animation and Variety Control of Crowds in Virtual Heritage

Daniel Thalmann, Sébastien Schertenleib, Jonathan Maim, Pablo Stanislaw De Heras Ciechomski

In this paper we propose a new method for rendering crowds of virtual humans with dynamicallydeformed skeletons with levels of detail using two simple caching schemes for animations and geometry. Weshow how the virtual heritage project ERATO pushed for the ...
