    • Smart Scribbles for Sketch Segmentation 

      Noris, G.; Sýkora, D.; Shamir, A.; Coros, S.; Whited, B.; Simmons, M.; Hornung, A.; Gross, M.; Sumner, R. (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present ‘Smart Scribbles’—a new scribble‐based interface for user‐guided segmentation of digital sketchy drawings. In contrast to previous approaches based on simple selection strategies, Smart Scribbles exploits richer ...

    • Comparison of Four Subjective Methods for Image Quality Assessment 

      Mantiuk, Rafał K.; Tomaszewska, Anna; Mantiuk, Radosław (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      To provide a convincing proof that a new method is better than the state of the art, computer graphics projects are often accompanied by user studies, in which a group of observers rank or rate results of several algorithms. ...

    • Interactive Character Animation Using Simulated Physics: A State‐of‐the‐Art Review 

      Geijtenbeek, T.; Pronost, N. (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Physics simulation offers the possibility of truly responsive and realistic animation. Despite wide adoption of physics simulation for the animation of passive phenomena, such as fluids, cloths and rag‐doll characters, ...

    • Temporal Blending for Adaptive SPH 

      Orthmann, Jens; Kolb, Andreas (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      In this paper, we introduce a fast and consistent smoothed particle hydrodynamics (SPH) technique which is suitable for convection–diffusion simulations of incompressible fluids. We apply our temporal blending technique ...

      In recent years, a collection of new techniques which deal with video as input data, emerged in computer graphics and visualization. In this survey, we report the state of the art in video‐based graphics and video ...

    • Computer Assisted Relief Generation—A Survey 

      Kerber, J.; Wang, M.; Chang, J.; Zhang, J. J.; Belyaev, A.; Seidel, H.‐P. (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      In this paper, we present an overview of the achievements accomplished to date in the field of computer‐aided relief generation. We delineate the problem, classify different solutions, analyse similarities, investigate ...

    • Low‐Complexity Intervisibility in Height Fields 

      Timonen, Ville (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Global illumination systems require intervisibility information between pairs of points in a scene. This visibility problem is computationally complex, and current interactive implementations for dynamic scenes are limited ...

    • Temporal Coherence Methods in Real‐Time Rendering 

      Scherzer, Daniel; Yang, Lei; Mattausch, Oliver; Nehab, Diego; Sander, Pedro V.; Wimmer, Michael; Eisemann, Elmar (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Nowadays, there is a strong trend towards rendering to higher‐resolution displays and at high frame rates. This development aims at delivering more detail and better accuracy, but it also comes at a significant cost. ...

    • Dependency‐Free Parallel Progressive Meshes 

      Derzapf, E.; Guthe, M. (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      The constantly increasing complexity of polygonal models in interactive applications poses two major problems. First, the number of primitives that can be rendered at real‐time frame rates is currently limited to a few ...

    • CageR: Cage‐Based Reverse Engineering of Animated 3D Shapes 

      Thiery, Jean‐Marc; Tierny, Julien; Boubekeur, Tamy (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present CageR: A novel framework for converting animated 3D shape sequences into compact and stable cage‐based representations. Given a raw animated sequence with one‐to‐one point correspondences together with an initial ...

    • Visualization for the Physical Sciences
