      Ruiters, Roland; Schwartz, Christopher; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Bidirectional Texture Functions (BTF) have proven to be a well-suited representation for the reproduction of measured real-world surface appearance and provide a high degree of realism. We present an approach for designing ...

      Schwartzburg, Yuliy; Pauly, Mark (The Eurographics Association and Blackwell Publishing Ltd., 2013)

    • Finite Element Image Warping 

      Kaufmann, Peter; Wang, Oliver; Sorkine-Hornung, Alexander; Sorkine-Hornung, Olga; Smolic, Aljoscha; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We introduce a single unifying framework for a wide range of content-aware image warping tasks using a finite element method (FEM). Existing approaches commonly define error terms over vertex finite differences and can be ...
    • Fleshing: Spine-driven Bending with Local Volume Preservation 

      Zhuo, Wei; Rossignac, Jarek (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Several design and animation techniques use a one-dimensional proxyC (a spine curve in 3D) to control the deformation or behavior of a digital model of a 3D shape S. We propose a modification of these ''skinning'' techniques ...
    • Freeform Shadow Boundary Editing 

      Mattausch, Oliver; Igarashi, Takeo; Wimmer, Michael (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present an algorithm for artistically modifying physically based shadows. With our tool, an artist can directly edit the shadow boundaries in the scene in an intuitive fashion similar to freeform curve editing. Our ...
    • Gaze-driven Object Tracking for Real Time Rendering 

      Mantiuk, Radoslaw; Bazyluk, Bartosz; Mantiuk, Rafal K. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      To efficiently deploy eye-tracking within 3D graphics applications, we present a new probabilistic method that predicts the patterns of user's eye fixations in animated 3D scenes from noisy eye-tracker data. The proposed ...
    • Geometry-Aware Volume-of-Fluid Method 

      Cho, Junghyun; Ko, Hyeong-Seok (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present a new framework to simulate moving interfaces in viscous incompressible two phase flows. The goal is to achieve both conservation of the fluid volume and a detailed reconstruction of the fluid surface. To these ...
    • Geosemantic Snapping for Sketch-Based Modeling 

      Shtof, Alex; Agathos, Alexander; Gingold, Yotam; Shamir, Ariel; Cohen-Or, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Modeling 3D objects from sketches is a process that requires several challenging problems including segmentation, recognition and reconstruction. Some of these tasks are harder for humans and some are harder for the machine. ...
    • Global Selection of Stream Surfaces 

      Esturo, Janick Martinez; Schulze, Maik; Rössl, Christian; Theisel, Holger (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Stream surfaces are well-known and widely-used structures for 3D flow visualization. A single surface can be sufficient to represent important global flow characteristics. Unfortunately, due to the huge space of possible ...
    • Interactive Exploration and Flattening of Deformed Historical Documents 

      Pal, Kazim; Terras, Melissa; Weyrich, Tim (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present an interactive application for browsing severely damaged documents and other cultural artefacts. Such documents often contain strong geometric distortions such as wrinkling, buckling, and shrinking and cannot ...
    • Interactive Facades - Analysis and Synthesis of Semi-Regular Facades 

      AlHalawani, Sawsan; Yang, Yong-Liang; Liu, Han; Mitra, Niloy J. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Urban facades regularly contain interesting variations due to allowed deformations of repeated elements (e.g., windows in different open or close positions) posing challenges to state-of-the-art facade analysis algorithms. ...
    • Landmark-Guided Elastic Shape Analysis of Spherically-Parameterized Surfaces 

      Kurtek, Sebastian; Srivastava, Anuj; Klassen, Eric; Laga, Hamid (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We argue that full surface correspondence (registration) and optimal deformations (geodesics) are two related problems and propose a framework that solves them simultaneously. We build on the Riemannian shape analysis of ...
    • Locally Adaptive Products for All-Frequency Relighting 

      Inger, Yaron; Farbman, Zeev; Lischinski, Dani (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Triple product integrals evaluate the shading at a point by factoring the reflection equation into incident illumination, visibility, and BRDF. By densely sampling the space of incident directions, this approach is capable ...
    • Material Editing in Complex Scenes by Surface Light Field Manipulation and Reflectance Optimization 

      Nguyen, Chuong H.; Scherzer, Daniel; Ritschel, Tobias; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      This work addresses the challenge of intuitive appearance editing in scenes with complex geometric layout and complex, spatially-varying indirect lighting. In contrast to previous work, that aimed to edit surface reflectance, ...
    • Measurement-Based Synthesis of Facial Microgeometry 

      Graham, Paul; Tunwattanapong, Borom; Busch, Jay; Yu, Xueming; Jones, Andrew; Debevec, Paul; Ghosh, Abhijeet (The Eurographics Association and Blackwell Publishing Ltd., 2013)

    • Mutable Elastic Models for Sculpting Structured Shapes 

      Milliez, Antoine; Wand, Michael; Cani, Marie-Paule; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      In this paper, we propose a new paradigm for free-form shape deformation. Standard deformable models minimize an energy measuring the distance to a single target shape. We propose a new, ''mutable'' elastic model. It ...

      Wu, Xiaoyue; Yang, Xubo; Yang, Yang (The Eurographics Association and Blackwell Publishing Ltd., 2013)

      Kaplanyan, Anton S.; Dachsbacher, Carsten (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We propose a simple yet powerful regularization framework for robust light transport simulation. It builds on top of existing unbiased methods and resorts to a consistent estimation using regularization only for paths which ...
