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
(2006)
Text en actes de congrés
Accés obertModern simulations and games have limited capabilities for simulated characters to interact with each other and with humans in rich, meaningful ways. Although significant achievements have been made in developing human ... -
Introductory graphics for very diverse audiences
(European Association for Computer Graphics (Eurographics), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents our first experience teaching WebGL in a master’s degree for a class of students with very different backgrounds. The main challenge was to prepare a course that would be engaging for students with ... -
La realidad virtual en el aprendizaje de historia mediante la interacción con humanoides virtuales
(2009)
Text en actes de congrés
Accés obertLa realidad virtual ofrece la posibilidad de interactuar de manera inmersiva en mundos virtuales 3D. Estos mundos virtuales pueden ser representaciones de otros momentos históricos que permiten al usuario explorar los ... -
Modeling crowd and trained leader behavior during building evacuation
(2006-11)
Article
Accés obertThis article considers animating evacuation in complex buildings by crowds who might not know the structure’s connectivity, or who find routes accidentally blocked. It takes into account simulated crowd behavior under two ... -
Multi-agent parallel hierarchical path finding in navigation meshes (MA-HNA*)
(2020-02)
Article
Accés obertOne of the main challenges in video games is to compute paths as efficiently as possible for groups of agents. As both the size of the environments and the number of autonomous agents increase, it becomes harder to obtain ... -
Multi-domain real-time planning in dynamic environments
(2013)
Comunicació de congrés
Accés restringit per política de l'editorialThis paper presents a real-time planning framework for multi-character navigation that enables the use of multiple heterogeneous problem domains of differing complexities for navigation in large, complex, dynamic virtual ... -
Output-sensitive rendering of detailed animated characters for crowd simulation
(2010)
Text en actes de congrés
Accés restringit per política de l'editorialRendering detailed animated characters is a major limiting factor in crowd simulation. In this paper we present a new representation for 3D animated characters which supports output-sensitive rendering. Each character is ... -
Procedural crowd generation for semantically augmented virtual cities
(2021-10)
Article
Accés obertAuthoring meaningful crowds to populate a virtual city can be a cumbersome, time-consuming and an error-prone task. In this work, we present a new framework for authoring populated environments in an easier and faster way, ... -
Procedural semantic cities
(European Association for Computer Graphics (Eurographics), 2017)
Text en actes de congrés
Accés obertProcedural modeling of virtual cities has achieved high levels of realism with little effort from the user. One can rapidly obtain a large city using off-the-shelf software based on procedural techniques, such as the use ... -
Simulating real-life scenarios to better understand the spread of diseases under different contexts
(Springer, 2024-02-01)
Article
Accés obertCurrent statistical models to simulate pandemics miss the most relevant information about the close atomic interactions between individuals which is the key aspect of virus spread. Thus, they lack a proper visualization ... -
Smooth transitioning between two walking metaphors for virtual reality applications
(European Association for Computer Graphics (Eurographics), 2019)
Text en actes de congrés
Accés obertVirtual navigation should be as similar as possible to how we move in the real world, however the limitations of hardware and physical space make this a challenging problem. Tracking natural walk is only feasible when the ... -
SparsePoser: Real-time full-body motion reconstruction from sparse data
(2023-10-31)
Article
Accés obertAccurate and reliable human motion reconstruction is crucial for creating natural interactions of full-body avatars in Virtual Reality (VR) and entertainment applications. As the Metaverse and social applications gain ... -
The impact of animations in the perception of a simulated crowd
(Springer, 2021)
