An approximation algorithm for computing the visibility region of a point on a terrain and visibility testing
(IEEE, 2014-01)Given a terrain and a query point p on or above it, we want to count the number of triangles of terrain that are visible from p. We present an approximation algorithm to solve this problem. We implement the algorithm and ... -
Emergency crowd simulation for outdoor environments
(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 ... -
Extraction of 3D navigation space in virtual urban environments
(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 ... -
“Night Hawks” watching over the city: redeployment of night watchmen and the politics of public space in Turkey
(Sage Publications, 2019-11)Technological advances have enormously increased surveillance techniques in the last three decades. In this article, we scrutinize the re-instatement of bekçi, the traditional night watchmen patrolling the residential ... -
A tool for pattern information extraction and defect quantification from crystal structures
(Elsevier, 2015)In this paper, we present a revised version of BilKristal 2.0 tool. We added defect quantification functionality to assess crystalline defects. We improved visualization capabilities by adding transparency support and ... -
Youtube vlogs, stardom and LGBTQ community
(Bilkent University, 2018-03)This thesis analyzes the rising importance of YouTube vlogs and vloggers against mainstream media organs in terms of self-representation and affiliation. The research specifically focuses on LGBTQ individuals’ sexual ...
