      The main research question for this work is: What are the factors involved in developing a three-dimensional (3D) interactive model of a bone fracture and how best may these be addressed? This paper presents work in progress ...
    • Differential Ray Marching 

      Muñoz, Adolfo (The Eurographics Association, 2012)
      Several participating media rendering algorithms are based on ray marching: they integrate the variations of radiance along the volume covered by the participating media by splitting the path of light into segments and ...
    • Diffusion and Fractional Diffusion Based Image Processing 

      Blackledge, Jonathan Michael (The Eurographics Association, 2009)
      We consider the background to describing strong scattering in terms of diffusive processes based on the diffusion equation. Intermediate strength scattering is then considered in terms of a fractional diffusion equation ...

      Tanasi, Davide; Milotta, Filippo L. M.; Gradante, Ilenia; Stanco, Filippo; Kaplan, Howard (The Eurographics Association, 2017)
      In the last decade the epigraphists have grown a new interest in signacula, a class of artifacts for a long time neglected. This has brought numerous contributions devoted to the different regional contexts, along with ...
    • Digitalización, Voxelización, Relleno y Esqueletonización 3D de Órganos Pares Duros de Cabra Montesa

      En este trabajo se describe el proceso para la representación computacional de órganos pares duros (cuernos) de cabra montesa (Capra pyrenaica) mediante la voxelización de su superficie, el relleno del interior y su ...
    • A Dimension-Independent and Extensible Framework for Huge Geometric Models 

      Canino, David (The Eurographics Association, 2010)
      Nowadays, gigantic models can be easily produced in many applications and their dimension often exceeds the RAM size in a common workstation. Thus, using an external memory technique is mandatory in this case. In this ...
    • Direct Scalar Field - to - Truss Representation and Stress Simulation of Open Pore Domains 

      Munoz, J. M.; Ruiz-Salguero, O.; Montoya-Zapata, D.; Cortes, C.; Cadavid, C. (The Eurographics Association, 2018)
      In the domain of lattice and porous material geometric modeling, the problem of data size is central. When using full 3D manifold Boundary Representations (BRep), even the smallest domains engender staggering amounts of ...
    • Direct Volume Rendering of Stack-Based Terrains 

      Graciano, Alejandro; Rueda, Antonio J.; Feito, Francisco R. (The Eurographics Association, 2017)
      Traditionally, the rendering of volumetric terrain data, as many other scientific 3D data, has been carried out performing direct volume rendering techniques on voxel-based representations. A main problem with this kind ...
    • Discrete Element Modelling Using a Parallelised Physics Engine 

      Longshaw, Stephen M.; Turner, Martin J.; Finch, Emma; Gawthorpe, Robert (The Eurographics Association, 2009)
      Discrete Element Modelling (DEM) is a technique used widely throughout science and engineering. It offers a convenient method with which to numerically simulate a system prone to developing discontinuities within its ...
    • Diseño de descomposiciones espaciales jerárquicas para mallas de triángulos utilizando Geometry Shaders 

      Delgado, Juan J. Jiménez; Albalá, Antonio Martínez; Higueruela, Francisco R. Feito (The Eurographics Association, 2009)
      Una de las principales ventajas de utilización de la GPU para la implementación de algoritmos geométricos es su especial diseño y adecuación para la realización de operaciones con vectores, su repertorio de operaciones ...
    • Dissipation Potentials for Yarn-Level Cloth 

      Sánchez-Banderas, Rosa M.; Otaduy, Miguel A. (The Eurographics Association, 2017)
      Damping is a critical phenomenon in determining the dynamic behavior of animated objects. For yarn-level cloth models, setting the correct damping behavior is particularly complicated, because common damping models in ...
    • Distance Based Feature Detection on 3D Point Sets 

      Ramli, Ahmad; Ivrissimtzis, Ioannis (The Eurographics Association, 2009)
      We propose a distance based algorithm for implicit feature detection on 3D point sets. Instead of directly determining whether a point belongs to a feature of the 3D point set or not, we first compute the distance between ...
    • A Distance Hierarchy to Detect Collisions Between Deformable Objects 

      Madera, Francisco A.; Day, Andy M.; Laycock, Stephen D. (The Eurographics Association, 2007)
      To detect collisions between deformable objects we introduce an algorithm that computes the closest distances between certain feature points defined in their meshes. The strategy is to divide the objects into regions and ...
