Crowd simulation incorporating agent psychological models, roles and communication
(2005)
Text en actes de congrés
Accés obertWe describe a new architecture to integrate a psychological model into a crowd simulation system in order to obtain believable emergent behaviors. Our existing crowd simulation system (MACES) performs high level wayfinding ... -
Efficient elimination of foot sliding for crowds
(2010)
Comunicació de congrés
Accés restringit per política de l'editorialThis poster presents an efficient Animation Planning Mediator (APM) designed to animate virtual characters in real time for crowd simulation. The APM selects the most appropriate animation clip available for each character ... -
Efficient rendering of animated characters through optimized per-joint impostors
(2012-02)
Article
Accés restringit per política de l'editorialIn this paper, we present a new impostor-based representation for 3D animated characters supporting real-time rendering of thousands of agents. We maximize rendering performance by using a collection of pre-computed ... -
Evacuation simulation models: challenges in modeling high rise building evacuation with cellular automata approaches
(2008-05)
Article
Accés restringit per política de l'editorialBuilding evacuation simulation provides designers with an efficient way of testing the safety of a building before construction. A significant number of models have been developed in a variety of disciplines (computer ... -
Exploiting the potential of image based crowd rendering
(European Association for Computer Graphics (Eurographics), 2015)
Comunicació de congrés
Accés restringit per política de l'editorialPer-joint impostors have been used to achieve high performance when rendering thousands of agents, while still allowing us to blend animation. This provides interactively animated crowds and reduces the memory footprint ... -
Exploring virtual reality as a validation methodology
([s.n.], 2008-06-30)
Text en actes de congrés
Accés obertVirtual environments can be used as a test bed for validation of human behavior simulation techniques since they place people within a simulated situation from an egocentric perspective. We propose level of presence achieved ... -
Feeling crowded yet?: Crowd simulations for VR
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés obertWith advances in virtual reality technology and its multiple applications, the need for believable, immersive virtual environments is increasing. Even though current computer graphics methods allow us to develop highly ... -
Feeling crowded? Exploring presence in virtual crowds
(2007)
Text en actes de congrés
Accés obertVirtual reality experiments with virtual crowds are necessary to study human behavior under panic or stressful situations that cannot be evaluated in the real world (i.e., building evacuation due to fire). In order to ... -
Fitted avatars: automatic skeleton adjustment for self-avatars in virtual reality
(2023-07-06)
Article
Accés obertIn the era of the metaverse, self-avatars are gaining popularity, as they can enhance presence and provide embodiment when a user is immersed in Virtual Reality. They are also very important in collaborative Virtual Reality ... -
Follower behavior under stress in immersive VR
(2020-12)
Article
Accés obertUnderstanding human decision making is a key requirement to improve crowd simulation models so that they can better mimic real human behavior. It is often difficult to study human decision making during dangerous situations ... -
Footstep parameterized motion blending using barycentric coordinates
(2015-04-01)
Article
Accés obertThis paper presents a real-time animation system for fully embodied virtual humans that satisfies accurate foot placement constraints for different human walking and running styles. Our method offers a fine balance between ... -
From one to many: Simulating groups of agents with reinforcement learning controllers
(2015)
Comunicació de congrés
Accés obertSimulation of crowd behavior has been approached through many different methodologies, but the problem of mimicking human decisions and reactions remains a challenge for all. We propose an alternative model for simulation ... -
Generating plausible individual agent movements from spatio-temporal occupancy data
(2007)
Text en actes de congrés
Accés restringit per política de l'editorialWe introduce the Spatio-Temporal Agent Motion Model, a datadriven representation of the behavior and motion of individuals within a space over the course of a day. We explore different representations for this model, ... -
GREIL-Crowds: crowd simulation with deep reinforcement learning and examples
(2023-08)
Article
Accés obertSimulating crowds with realistic behaviors is a difficult but very important task for a variety of applications. Quantifying how a person balances between different conflicting criteria such as goal seeking, collision ... -
Hierarchical path-finding for Navigation Meshes (HNA*)
(2016-10-01)
Article
Accés obertPath-finding can become an important bottleneck as both the size of the virtual environments and the number of agents navigating them increase. It is important to develop techniques that can be efficiently applied to any ... -
Impostor-based crowd rendering
(CRC Press, 2016-09-27)
Capítol de llibre
Accés restringit per política de l'editorialReal-time rendering of detailed animated characters in crowd simulations is still a challenging problem in computer graphics. State-of-the-art approaches can render up to several thousand agents by consuming most of the ... -
Improving the realism of agent movement for high density crowd simulation
(2006)
Comunicació de congrés
Accés restringit per política de l'editorialSimulating realistic, large, dense crowds of autonomous agents is still a challenge for the computer graphics community. Typical approaches either look like particle simulations (where agents ‘vibrate’ back and forth) or ... -
Interoperable human behavior models for simulations
