      Herholz, Philipp; Haase, Felix; Alexa, Marc (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We define Voronoi cells and centroids based on heat diffusion. These heat cells and heat centroids coincide with the common definitions in Euclidean spaces. On curved surfaces they compare favorably with definitions based ...
    • EcoBrush: Interactive Control of Visually Consistent Large-Scale Ecosystems 

      Gain, James; Long, Harry; Cordonnier, Guillaume; Cani, Marie-Paule (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      One challenge in portraying large-scale natural scenes in virtual environments is specifying the attributes of plants, such as species, size and placement, in a way that respects the features of natural ecosystems, while ...
    • Enriching Facial Blendshape Rigs with Physical Simulation 

      Kozlov, Yeara; Bradley, Derek; Bächer, Moritz; Thomaszewski, Bernhard; Beeler, Thabo; Gross, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Oftentimes facial animation is created separately from overall body motion. Since convincing facial animation is challenging enough in itself, artists tend to create and edit the face motion in isolation. Or if the face ...
    • EUROGRAPHICS 2017: CGF 36-2 Frontmatter 

      Barthe, Loïc; Benes, Bedrich (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    • Flicker Observer Effect: Guiding Attention Through High Frequency Flicker in Images 

      Waldin, Nicholas; Waldner, Manuela; Viola, Ivan (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Drawing the user's gaze to an important item in an image or a graphical user interface is a common challenge. Usually, some form of highlighting is used, such as a clearly distinct color or a border around the item. Flicker ...
    • Flow-Induced Inertial Steady Vector Field Topology 

      Günther, Tobias; Gross, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Traditionally, vector field visualization is concerned with 2D and 3D flows. Yet, many concepts can be extended to general dynamical systems, including the higher-dimensional problem of modeling the motion of finite-sized ...
    • Fully Spectral Partial Shape Matching 

      Litany, Or; Rodolà, Emanuele; Bronstein, Alex M.; Bronstein, Michael M. (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We propose an efficient procedure for calculating partial dense intrinsic correspondence between deformable shapes performed entirely in the spectral domain. Our technique relies on the recently introduced partial functional ...
    • General Point Sampling with Adaptive Density and Correlations 

      Roveri, Riccardo; Öztireli, A. Cengiz; Gross, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Analyzing and generating sampling patterns are fundamental problems for many applications in computer graphics. Ideally, point patterns should conform to the problem at hand with spatially adaptive density and correlations. ...
    • Geometric Stiffness for Real-time Constrained Multibody Dynamics 

      Andrews, Sheldon; Teichmann, Marek; Kry, Paul G. (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper focuses on the stable and efficient simulation of articulated rigid body systems for real-time applications. Specifically, we focus on the use of geometric stiffness, which can dramatically increase simulation ...
    • GPU Ray Tracing using Irregular Grids 

      Pérard-Gayot, Arsène; Kalojanov, Javor; Slusallek, Philipp (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a spatial index structure to accelerate ray tracing on GPUs. It is a flat, non-hierarchical spatial subdivision of the scene into axis aligned cells of varying size. In order to construct it, we first nest an ...
    • A GPU-Adapted Structure for Unstructured Grids 

      Zayer, Rhaleb; Steinberger, Markus; Seidel, Hans-Peter (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      A key advantage of working with structured grids (e.g., images) is the ability to directly tap into the powerful machinery of linear algebra. This is not much so for unstructured grids where intermediate bookkeeping data ...
    • Gradient-based Steering for Vision-based Crowd Simulation Algorithms 

      Dutra, Teofilo B.; Marques, Ricardo; Cavalcante-Neto, Joaquim Bento; Vidal, Creto A.; Pettré, Julien (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Most recent crowd simulation algorithms equip agents with a synthetic vision component for steering. They offer promising perspectives through a more realistic simulation of the way humans navigate according to their ...
