    • ACMICS: an agent communication model for interacting crowd simulation 

      Kullu, K.; Güdükbay U.; Manocha, D. (Springer, 2017)
      Behavioral plausibility is one of the major aims of crowd simulation research. We present a novel approach that simulates communication between the agents and assess its influence on overall crowd behavior. Our formulation ...
    • ACMICS: An agent communication model for interacting crowd simulation: JAAMAS track 

      Kullu, K.; Güdükbay U.; Manocha, D. (International Foundation for Autonomous Agents and Multiagent Systems (IFAAMAS), 2018)
      We present and evaluate a novel approach to simulate communication between the agents. Our approach distinguishes low- And high-level communication tasks. This separation makes it easy to extend and use it in new scenarios. ...
    • Adaptive grids: an image-based approach to generate navigation meshes 

      Akaydın, A.; Güdükbay, U. (S P I E - International Society for Optical Engineering, 2013-02-01)
      We propose adaptive grids, an image-based approach for constructing navigation meshes, which are used for path planning. A cellular navigation mesh, called an adaptive grid, is constructed from a top-view range image of a ...
    • Communication models for crowd simulation 

      Küllü, Kurtuluş (Bilkent University, 2017-08)
      Modeling and animation of behaviorally plausible virtual crowds are important problems of crowd simulation research. We propose a communication model in order to equip virtual agents with the ability to autonomously ...
    • Creating crowd variation with the OCEAN personality model 

      Durupınar, Funda; Allbeck, J.; Pelechano, N.; Badler, N. (IFAAMAS, 2008-05)
      Most current crowd simulators animate homogeneous crowds, but include underlying parameters that can be tuned to create variations within the crowd. These parameters, however, are specific to the crowd models and may be ...
    • Dynamic point-region quadtrees for particle simulations 

      Oğuz, O.; Durupınar, F.; Güdükbay U. (Elsevier Inc., 2013)
      We propose an algorithm for dynamically updating point-region (PR) quadtrees. Our algorithm is optimized for simultaneous update of data points comprising a quadtree. The intended application area focuses on simulating ...
    • Emergency crowd simulation for outdoor environments 

      Oğuz, O.; Akaydın, A.; Yilmaz, T.; Güdükbay U. (Pergamon Press, 2010)
      We simulate virtual crowds in emergency situations caused by an incident, such as a fire, an explosion, or a terrorist attack. We use a continuum dynamics-based approach to simulate the escaping crowd, which produces more ...
    • From audiences to mobs : crowd simulation with psychological factors 

      Durupınar, Funda (Bilkent University, 2010)
      Crowd simulation has a wide range of application areas such as biological and social modeling, military simulations, computer games and movies. Simulating the behavior of animated virtual crowds has been a challenging ...
    • A group-based approach for gaze behavior of virtual crowds incorporating personalities 

      Ağıl, U.; Güdükbay U. (John Wiley and Sons, 2018)
      Predicting interest points of virtual characters and accurately simulating their gaze behavior play a significant role for realistic crowd simulations. We propose a saliency model that enables virtual agents to produce ...
    • How the ocean personality model affects the perception of crowds 

      Durupınar, F.; Pelechano, N.; Allbeck, J. M.; Güdükbay U.; Badler, N. I. (Institute of Electrical and Electronics Engineers, 2011)
      A personality model named High-Density Autonomous Crowds (HiDAC) simulation system provides individual differences by assigning each person different psychological and physiological traits. Users normally set these parameters ...
    • Learning from real-life experiences: a data-driven emotion contagion approach towards realistic virtual crowds 

      Başak, Ahmet Eren (Bilkent University, 2017-10)
      We propose a data-driven approach for tuning, validating and optimizing crowd simulations by learning parameters from real-life videos. We discuss the common traits of incidents and their video footages suitable for the ...
    • Modeling and populating virtual cities: automatic production of building models and emergency crowd simulation 

      Oğuz, Oğuzcan (Bilkent University, 2008)
      In this thesis, we present an automatic building generation method based on procedural modeling approach, and a crowd animation system that simulates a crowd of pedestrians inside a city. While modeling the buildings, ...
    • Psychological parameters for crowd simulation: from audiences to mobs 

      Durupınar, F.; Güdükbay U.; Aman, A.; Badler, N. I. (Institute of Electrical and Electronics Engineers, 2016)
      In the social psychology literature, crowds are classified as audiences and mobs. Audiences are passive crowds, whereas mobs are active crowds with emotional, irrational and seemingly homogeneous behavior. In this study, ...
    • Realistic modeling of spectator behavior for soccer videogames with CUDA 

      Ylmaz, E.; Molla, E.; Yıldız, C.; İşler V. (2011)
      Soccer has always been one of the most popular videogame genres. When designing a soccer game, designers tend to focus on the game field and game play due to the limited computational resources, and thus the modelling of ...
    • Simulating gaze behavior of virtual crowds by predicting interest points 

      Ağıl, Umut (Bilkent University, 2016-08)
      Creating realistic crowd behavior is one of the major goals in crowd simulations. Simulating gaze behavior and predicting interest points of virtual characters play a signifficant role in creating believable scenes, however ...
