    • Approximation algorithms for visibility computation and testing over a terrain 

      Alipour S.; Ghodsi M.; Güdükbay, Uğur; Golkari M. (Springer, 2017)
      Given a 2.5D terrain and a query point p on or above it, we want to find the triangles of terrain that are visible from p. We present an approximation algorithm to solve this problem. We implement the algorithm and test ...

    • Extraction of 3D navigation space in virtual urban environments 

      Yılmaz, Türker; Güdükbay, Uğur (IEEE, 2005-09)
      Urban scenes are one class of complex geometrical environments in computer graphics. In order to develop navigation systems for urban sceneries, extraction and cellulization of navigation space is one of the most commonly ...
