    • Concepts and Algorithms for the Deformation, Analysis, andCompression of Digital Shapes 

      von Tycowicz, Christoph (von Tycowicz, 2014-05-05)
      We propose new model reduction techniques for the construction of reducedshape spaces of deformable objects and for the approximation ofreduced internal forces that accelerate the construction of a reduced dynamicalsystem, ...

    • Understanding the Structure of 3D Shapes: PolyCubes and Curve-Skeletons 

      Livesu, Marco (Livesu, 2014-05-23)
      Compact representations of three dimensional objects are very often usedin computer graphics to create effective ways to analyse, manipulate andtransmit 3D models. Their ability to abstract from the concrete shapes andexpose ...

    • Image Space Adaptive Rendering 

      Rousselle, Fabrice (2014-06-06)
      In this thesis, we develop an adaptive framework for Monte Carlo rendering, and more specifically for Monte Carlo Path Tracing (MCPT) and its derivatives. MCPT is attractive because it can handle a wide variety of light ...

    • Computational Shape Understanding for 3D Reconstruction and Modeling 

      Ceylan, Duygu (Ceylan, 2014-06-10)
      The physical and the digital world are becoming tightly connected as we see an increase in thevariety of 2D and 3D acquisition devices, e.g., smartphones, digital camera, scanners, commercialdepth sensors. The recent ...

    • Interactions with Gigantic Point Clouds 

      Scheiblauer, Claus (2014-06-25)
      During the last decade the increased use of laser range-scanners for sampling the environment has led to gigantic point cloud data sets. Due to the size of such data sets, tasks like viewing, editing, or presenting the ...

    • Inverse rendering for scene reconstruction in general environments 

      Wu, Chenglei (Wu, Chenglei, 2014-07-10)
      Demand for high-quality 3D content has been exploding recently, owing to the advances in 3D displays and 3D printing. However, due to insufficient 3D content, the potential of 3D display and printing technology has ...
