    • Conservative occlusion culling for urban visualization using a slice-wise data structure 

      Yılmaz, T.; Güdükbay U. (Academic Press, 2007)
      In this paper, we propose a framework for urban visualization using a conservative from-region visibility algorithm based on occluder shrinking. The visible geometry in a typical urban walkthrough mainly consists of partially ...
    • 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 ...
    • Ray tracing geometric models and parametric surfaces 

      İşler, Veysi (Bilkent University, 1989)
      In many computer graphics applications such as CAD, realistic displays have very important and positive effects on designers using the system. There axe several techniques to generate realistic images with the computer. ...
    • Scene representation technologies for 3DTV-a survey 

      Alatan, A. A.; Yemez, Y.; Güdükbay U.; Zabulis, X.; Müller, K.; Erdem, C.; Weigel, C.; Smolic, A. (Institute of Electrical and Electronics Engineers, 2007-11)
      3-D scene representation is utilized during scene extraction, modeling, transmission and display stages of a 3DTV framework. To this end, different representation technologies are proposed to fulfill the requirements of ...
