    Silvennoinen, Ari; Saransaari, Hannu; Laine, Samuli; Lehtinen, Jaakko (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present a method for extreme occluder simplification. We take a triangle soup as input, and produce a small set of polygons with closely matching occlusion properties. In contrast to methods that optimize the original ...
  • Time Line Cell Tracking for the Approximation of Lagrangian Coherent Structures with Subgrid Accuracy 

    Kuhn, A.; Engelke, W.; Rössl, C.; Hadwiger, M.; Theisel, H. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Lagrangian coherent structures (LCSs) have become a widespread and powerful method to describe dynamic motion patterns in time-dependent flow fields. The standard way to extract LCS is to compute height ridges in the ...
  • On Perception of Semi‐Transparent Streamlines for Three‐Dimensional Flow Visualization 

    Mishchenko, O.; Crawfis, R. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    One of the standard techniques to visualize three‐dimensional flow is to use geometry primitives. This solution, when opaque primitives are used, results in high levels of occlusion, especially with dense streamline seeding. ...
  • Modelling of Non‐Periodic Aggregates Having a Pile Structure 

    Sakurai, K.; Miyata, K. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    This paper presents a procedure for modelling aggregates such as piles that consist of arbitrary components. The method generates an aggregate of components that need to be accumulated, and an aggregate shape represents ...
  • Low‐Cost Subpixel Rendering for Diverse Displays 

    Engelhardt, Thomas; Schmidt, Thorsten‐Walther; Kautz, Jan; Dachsbacher, Carsten (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Subpixel rendering increases the apparent display resolution by taking into account the subpixel structure of a given display. In essence, each subpixel is addressed individually, allowing the underlying signal to be sampled ...
  • Multi‐Scale Kernels Using Random Walks 

    Sinha, A.; Ramani, K. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We introduce novel multi‐scale kernels using the random walk framework and derive corresponding embeddings and pairwise distances. The fractional moments of the rate of continuous time random walk (equivalently diffusion ...
  • Projection Mapping on Arbitrary Cubic Cell Complexes 

    Apaza‐Agüero, K.; Silva, L.; Bellon, O. R. P.  (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    This work presents a new representation used as a rendering primitive of surfaces. Our representation is defined by an arbitrary cubic cell complex: a projection‐based parameterization domain for surfaces where geometry ...
  • Image Space Rendering of Point Clouds Using the HPR Operator 

    Silva, R. Machado e; Esperança, C.; Marroquim, R.; Oliveira, A. A. F. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    The hidden point removal (HPR) operator introduced by Katz et al. [KTB07] provides an elegant solution for the problem of estimating the visibility of points in point samplings of surfaces. Since the method requires computing ...
  • Stackless Multi‐BVH Traversal for CPU, MIC and GPU Ray Tracing 

    Áfra, Attila T.; Szirmay‐Kalos, László (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Stackless traversal algorithms for ray tracing acceleration structures require significantly less storage per ray than ordinary stack‐based ones. This advantage is important for massively parallel rendering methods, where ...
  • Implicit Decals: Interactive Editing of Repetitive Patterns on Surfaces 

    Groot, Erwin; Wyvill, Brian; Barthe, Loïc; Nasri, Ahmad; Lalonde, Paul (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Texture mapping is an essential component for creating 3D models and is widely used in both the game and the movie industries. Creating texture maps has always been a complex task and existing methods carefully balance ...
  • Visibility Silhouettes for Semi‐Analytic Spherical Integration 

    Nowrouzezahrai, Derek; Baran, Ilya; Mitchell, Kenny; Jarosz, Wojciech (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    At each shade point, the spherical visibility function encodes occlusion from surrounding geometry, in all directions. Computing this function is difficult and point‐sampling approaches, such as ray‐tracing or hardware ...
  • Subdivision Surfaces with Creases and Truncated Multiple Knot Lines 

    Kosinka, J.; Sabin, M. A.; Dodgson, N. A. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We deal with subdivision schemes based on arbitrary degree B‐splines. We focus on extraordinary knots which exhibit various levels of complexity in terms of both valency and multiplicity of knot lines emanating from such ...

  • Visualization of the Centre of Projection Geometrical Locus in a Single Image 

    Stojaković, V.; Popov, S.; Tepavčević, B. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Single view reconstruction (SVR) is an important approach for 3D shape recovery since many non‐existing buildings and scenes are captured in a single image. Historical photographs are often the most precise source for ...
