    • Dynamic point-region quadtrees for particle simulations 

      Oğuz, O.; Durupınar, F.; Güdükbay, Uğur (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 ...
    • How the ocean personality model affects the perception of crowds 

      Durupınar, F.; Pelechano, N.; Allbeck, J. M.; Güdükbay, Uğur; 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 ...
    • Procedural visualization of knitwear and woven cloth 

      Durupınar, F.; Güdükbay, Uğur (Pergamon Press, 2007-11)
      In this paper, a procedural method for the visualization of knitted and woven fabrics is presented. The proposed method is compatible with a mass-spring model and makes use of the regular warp-weft structure of the cloth. ...
    • Psychological parameters for crowd simulation: from audiences to mobs 

      Durupınar, F.; Güdükbay, Uğur; 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, ...
    • Using real life incidents for creating realistic virtual crowds with data-driven emotion contagion 

      Başak, Ahmet Eren; Güdükbay, Uğur; Durupınar, F. (Pergamon Press, 2018)
      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 ...
    • Visualization of crowd synchronization on footbridges 

      Durupınar, F.; Güdükbay, Uğur (Springer, 2010)
      This paper proposes a framework for the visualization of crowd walking synchronization on footbridges. The bridge is modeled as a mass-spring system, which is a weakly damped and driven harmonic oscillator. Both the bridge ...
