      Fantoni, Simone; Castellani, Umberto; Fusiello, Andrea (The Eurographics Association, 2012)
      In this paper we tackle the problem of automatically aligning an unordered set of range views. We propose a full pipeline that goes from the scans to the complete 3D model. The emphasis is on the automation no manual ...
    • 3D Material Style Transfer 

      Nguyen, Chuong H.; Ritschel, Tobias; Myszkowski, Karol; Eisemann, Elmar; Seidel, Hans-Peter (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      This work proposes a technique to transfer the material style or mood from a guide source such as an image or video onto a target 3D scene. It formulates the problem as a combinatorial optimization of assigning discrete ...
    • Incoherent Ray Tracing without Acceleration Structures 

      Áfra, Attila T. (The Eurographics Association, 2012)
      Recently, a new family of dynamic ray tracing algorithms, called divide-and-conquer ray tracing, has been introduced. This approach partitions the primitives on-the-fly during ray traversal, which eliminates the need for ...

      Birklbauer, Clemens; Bimber, Oliver (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      We present a first approach to light-field retargeting using z-stack seam carving, which allows light-field compression and extension while retaining angular consistency. Our algorithm first converts an input light field ...
    • Symmetry in 3D Geometry: Extraction and Applications 

      Mitra, Niloy J.; Pauly, Mark; Wand, Michael; Ceylan, Duygu (The Eurographics Association, 2012)
      The concept of symmetry has received significant attention in computer graphics and computer vision research in recent years. Numerous methods have been proposed to find and extract geometric symmetries and exploit such ...
    • Multitouch Gestures for Constrained Transformation of 3D Objects 

      Au, Oscar Kin-Chung; Tai, Chiew-Lan; Fu, Hongbo (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      3D transformation widgets allow constrained manipulations of 3D objects and are commonly used in many 3D applications for fine-grained manipulations. Since traditional transformation widgets have been mainly designed for ...
    • Perceptually Linear Parameter Variations 

      Lindow, Norbert; Baum, Daniel; Hege, Hans-Christian (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      Most visual analysis tasks require interactive adjustment of parameter values. In general, a linear variation of a parameter, using for instance a GUI slider, changes the visual result in a perceptually non-linear way. ...
    • Automatically Rigging Multi-component Characters 

      Bharaj, Gaurav; Thormählen, Thorsten; Seidel, Hans-Peter; Theobalt, Christian (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      Rigging an arbitrary 3D character by creating an animation skeleton is a time-consuming process even for experienced animators. In this paper, we present an algorithm that automatically creates animation rigs for multicomponent ...
    • Hyperplane Culling for Stochastic Rasterization 

      Munkberg, Jacob; Akenine-Möller, Tomas (The Eurographics Association, 2012)
      We present two novel culling tests for rasterization of simultaneous depth of field and motion blur. These tests efficiently reduce the set of xyuvt samples that need to be coverage tested within a screen space tile. The ...
    • Automatic Line Handles for Freeform Deformation 

      Schemali, Leïla; Thiery, Jean-Marc; Boubekeur, Tamy (The Eurographics Association, 2012)
      Interactive freeform surface deformation methods allow to explore the space of possible shapes using simple control structures. While recent advances in variational editing provide high quality deformations, designing ...
    • On User-Interaction in 3D Reconstruction 

      Schneider, David C.; Eisert, Peter (The Eurographics Association, 2012)
      For many computer graphics tasks such as segmentation, tracking or retargeting, algorithms are designed to allow user interaction. For real-world applications, tools which give users some form of control are often preferred ...
    • Evaluation of a Curriculum for Technical Artists 

      Sundstedt, Veronica; Lanner, Martin (The Eurographics Association, 2012)
      A Technical Artist requires a unique set of skills to act as a bridge between artists and programmers in digital entertainment development. Our newly developed Technical Artist in Games (TAG) program is regulated under the ...
    • A Pipeline for Procedural Modelling from Geospatial Data 

      Jesus, Diego; Coelho, António; Rebelo, C.; Cardoso, A.; Sousa, A. A. (The Eurographics Association, 2012)
      Virtual urban environments can be used for purposes like municipality planning and management. Due to the complexity and large extent of these environments procedural modelling techniques can be used to generate these 3D ...
    • Steady State Stokes Flow Interpolation for Fluid Control 

      Bhatacharya, Haimasree; Nielsen, Michael B.; Bridson, Robert (The Eurographics Association, 2012)
      Fluid control methods often require surface velocities interpolated throughout the interior of a shape to use the velocity as a feedback force or as a boundary condition. Prior methods for interpolation in computer graphics ...
    • Efficient Evaluation of Semi-Smooth Creases in Catmull-Clark Subdivision Surfaces 

      Nießner, Matthias; Loop, Charles; Greiner, Günther (The Eurographics Association, 2012)
