    • 3D Hair sketching for real-time dynamic & key frame animations 

      Aras, R.; Başarankut, B.; Çapın, T.; Özgüç, B. (Springer, 2008-07)
      Physically based simulation of human hair is a well studied and well known problem. But the "pure" physically based representation of hair (and other animation elements) is not the only concern of the animators, who want ...
    • Animated mesh simplification based on saliency metrics 

      Tolgay, Ahmet (Bilkent University, 2008)
      Mesh saliency identifies the visually important parts of a mesh. Mesh simplification algorithms using mesh saliency as simplification criterion preserve the salient features of a static 3D model. In this thesis, we propose ...
    • Animation of boiling phenomena 

      Bulbul, A.; Kucuktunc, O.; Ozguc, B. (2008)
      Phenomenon of boiling is a challenging topic for computer graphics due to its complex hydrodynamics and formulation. Realistic fluid animations require very heavy three-dimensional fluid flow calculations, and surface ...
    • Animation of deformable models 

      Güdükbay U.; Özgüç, B. (Pergamon Press, 1994)
      Although kinematic modelling methods are adequate for describing the shapes of static objects, they are insufficient when it comes to producing realistic animation. Physically based modelling remedies this problem by ...
    • An animation system for fracturing of rigid objects 

      Küçükyilmaz, A.; Özgüç, B. (Springer, 2005)
      This paper describes a system for the animation of fracturing brittle objects. The system combines rigid body simulation methods with a constraint-based model to animate fracturing of arbitrary polyhedral shaped objects ...
    • Animator's hell : an animation inspired by Sartre's other 

      Akgülgil, Nadide Gizem (Bilkent University, 2012)
      Animation is a form that allows the animator to enter a world of impossibilities. Things that are hard or impossible to show in live action become easier or possible in animation. The animator as a subject animates an ...
    • Combined filtering and key-frame reduction of motion capture data with application to 3DTV 

      Önder O.; Erdem Ç.; Erdem, T.; Güdükbay, U.; Özgüç, B. (2006)
      A new method for combined filtering and key-frame reduction of motion capture data is proposed. Filtering of motion capture data is necessary to eliminate any jitter introduced by a motion capture system. Key-frame reduction, ...
    • Creating crowd variation with the OCEAN personality model 

      Durupinar F.; Allbeck J.; Pelechano, N.; Badler, N. (International Foundation for Autonomous Agents and Multiagent Systems (IFAAMAS), 2008)
      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 ...
    • A decision theoretic approach to motion saliency in computer animations 

      Arpa, S.; Bulbul, A.; Capin, T. (IEEE, 2011)
      We describe a model to calculate saliency of objects due to their motions. In a decision-theoretic fashion, perceptually significant objects inside a scene are detected. The work is based on psychological studies and ...
    • 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 ...
    • Example based retargeting human motion to arbitrary mesh models 

      Yaz, İlker O (Bilkent University, 2013)
      Animation of mesh models can be accomplished in many ways, including character animation with skinned skeletons, deformable models, or physic-based simulation. Generating animations with all of these techniques is time ...
    • Example-based retargeting of human motion to arbitrary mesh models 

      Celikcan, U.; Yaz I.O.; Capin, T. (Blackwell Publishing Ltd, 2015)
      We present a novel method for retargeting human motion to arbitrary 3D mesh models with as little user interaction as possible. Traditional motion-retargeting systems try to preserve the original motion, while satisfying ...
    • Keyframe reduction techniques for motion capture data 

      Önder O.; Güdükbay U.; Özgüç, B.; Erdem, T.; Erdem Ç.; Özkan, M. (2008)
      Two methods for keyframe reduction of motion capture data are presented. Keyframe reduction of motion capture data enables animators to easily edit motion data with smaller number of keyframes. One of the approaches achieves ...
    • Kubo ... And The Two Strings 

      Haimes, Marc; Butler, Chris; Tindle, Shannon; Haimes, Marc; Knight, Travis (2016-01-05)
    • Mars: A tool-based modeling, animation, and parallel rendering system 

      Aktıhanoğlu, M.; Özgüç, B.; Aykanat, C. (Springer, 1994)
      This paper describes a system for modeling, animating, previewing and rendering articulated objects. The system has a modeler of objects that consists of joints and segments. The animator interactively positions the ...
    • Media convergence in animation : an analysis of aesthetic uniformity 

      Gündeş, Feridun (Bilkent University, 2017-02)
      This thesis analyzes the uniformity in animation aesthetics within the framework of convergence theory. The sources of aesthetic diversity in animation art are demonstrated along with the process though which these became ...
    • Motion based clustering of model animations using PCA 

      Köse, K.; Çetin, A.E. (2009)
      In the last few years, there is great increase in capture and representation of real 3-Dimensonal scenes using 3D animation models. The 3D signals are then compressed, transmitted to the client side and reconstructed for ...
    • Motion capture and human pose reconstruction from a single-view video sequence 

      Güdükbay U.; Demir, I.; Dedeoǧlu, Y. (Academic Press, 2013)
      We propose a framework to reconstruct the 3D pose of a human for animation from a sequence of single-view video frames. The framework for pose construction starts with background estimation and the performer's silhouette ...
