    • Filament-Based Smoke 

      Weißmann, Steffen (Weißmann, 15. 9. 201)
      This cumulative dissertation presents a complete model for simulating smoke usingpolygonal vortex filaments. Based on a Hamiltonian system for the dynamics ofsmooth vortex filaments, we develop an effcient and robust ...

    • Human Visual System Models in Computer Graphics 

      Aydin, Tunc Ozan (Tunc Ozan Aydin, 2011-10-11)
      At the receiving end of visual data are humans; thus it is only natural to takeinto account various properties and limitations of the human visual system whiledesigning new image and video processing methods. In this ...

    • Hybrid Methods for Interactive Shape Manipulation 

      Weber (Weber, 2010-09-12)
      Manipulating 2D and 3D shapes interactively is an important task in computer graphics. The challenge is to be able to induce a global change to the shape while preserving its local structure. A deformation tool accepts as ...

    • Measurement-based modeling and fabrication of deformable materials for human faces 

      Bickel, Bernd (Bickel, 2010)
      <p>This thesis investigates the combination of data-driven and physically basedtechniques for acquiring, modeling, and animating deformable materials,with a special focus on human faces. Furthermore, based on these ...

    • NURBS-compatible subdivision surfaces 

      Cashman, Thomas J. (Cashman, Thomas J., Mar 2010)
      Two main technologies are available to design and represent freeformsurfaces: Non-Uniform Rational B-Splines (NURBS) and subdivision surfaces. Both representations are built on uniform B-splines, but they extend this ...

    • Process-Based Design of Multimedia Annotation Systems 

      Hofmann, Cristian Erick (Hofmann, 06.12.2010)
      Annotation of digital multimedia comprises a range of different application scenarios,supported media and annotation formats, and involved techniques. Accordingly, recentannotation environments provide numerous functions ...

    • Processing of Façade Imagery 

      Musialski, Przemyslaw (Musialski, 2010)
      Modeling and reconstruction of urban environments is currently the subject of intensive research. There is a wide range of possible applications, including virtual environments ...

    • Real-time High Quality HDR Illumination and Tonemapped Rendering 

      Michael, Despina (Michael, 2010-07-10)
      Real-time realistic rendering of a computer generated scene is one of the core research areas in computer graphics as it is required in several applications such as computer games, training simulators, medical and architectural ...

    • Reconsidering Light Transport - Acquisition and Display of Real-World Reflectance and Geometry 

      Hullin, Matthias (Matthias Hullin, 2010-12-15)
      In this thesis, we cover three scenarios that violate common simplifying assumptions about the nature of light transport. We begin with the first ingredient to any 3D rendering: a geometry model. Most 3D scanners require ...

    • A Robust Approach to Interactive Virtual Cutting: Geometry and Color 

      Pietroni, Nico (Pietroni, 2010-05-08)
      Interactive simulation of deformable bodies has attracted growing interest in the course of the last decade and, while for a long time it has been limited to applicative domains such as virtual surgery, it is nowadays a ...

    • A Stochastic Parallel Method for Real Time Monocular SLAM Applied to Augmented Reality 

      Sanchez Tapia, Jairo Roberto (Sanchez Tapia, 2010-12-10)
      In augmented reality applications, the position and orientation of the observermust be estimated in order to create a virtual camera that renders virtual objectsaligned with the real scene. There are a wide variety of ...

    • Study of parallel techniques applied to surface reconstruction from unorganized and unoriented point clouds 

      Buchart Izaguirre, Carlos Ignacio (Buchart Izaguirre, 2010-12-13)
      Nowadays, digital representations of real objects are becoming biggeras scanning processes are more accurate, so the time required for thereconstruction of the scanned models is also increasing.This thesis studies the ...

    • Visibility Computations for Real-Time Rendering in General 3D Environments 

      Mattausch, Oliver (Mattausch, 27.4.2010)
      Visibility computations are essential operations in computer graphics, which are required for rendering acceleration in the form of visibility culling, as well as for computing realistic lighting. Visibility culling, which ...

    • Visual Analytics of Large Weighted Directed Graphs and Two-Dimensional Time-Dependent Data
