      In this paper, we present an inexpensive approach to create highly detailed reconstructions of the landscape surrounding a road. Our method is based on a space-efficient semi-procedural representation of the terrain and ...

    • Inherent Noise-Aware Insect Swarm Simulation 

      Wang, Xinjie; Jin, Xiaogang; Deng, Zhigang; Zhou, Linling (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Collective behaviour of winged insects is a wondrous and familiar phenomenon in the real world. In this paper, we introduce a highly efficient field-based approach to simulate various insect swarms. Its core idea is to ...

    • Inverse Procedural Modelling of Trees 

      Stava, O.; Pirk, S.; Kratt, J.; Chen, B.; Mech, R.; Deussen, O.; Benes, B. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Procedural tree models have been popular in computer graphics for their ability to generate a variety of output trees from a set of input parameters and to simulate plant interaction with the environment for a realistic ...

    • Modelling Cumulus Cloud Shape from a Single Image 

      Yuan, Chunqiang; Liang, Xiaohui; Hao, Shiyu; Qi, Yue; Zhao, Qinping (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Clouds are important components of the fascinating natural images. However, extracting cloud shapes from images remains a challenging task. This paper presents a calculation method for estimating the shape of a cumulus ...

    • Out-of-Core Construction of Sparse Voxel Octrees 

      Baert, J.; Lagae, A.; Dutré, Ph. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Voxel-based rendering has recently received significant attention due to its potential in the context of efficiently rendering massively large and highly detailed scenes. Unfortunately, few scenes are available in the form ...

    • PackMerger: A 3D Print Volume Optimizer 

      Vanek, J.; Galicia, J. A. Garcia; Benes, B.; Mech, R.; Carr, N.; Stava, O.; Miller, G. S. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We propose an optimization framework for 3D printing that seeks to save printing time and the support material required to print 3D shapes. Three-dimensional printing technology is rapidly maturing and may revolutionize ...

    • Partial 3-D Correspondence from Shape Extremities 

      Sahillioglu, Y.; Yemez, Y. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a 3-D correspondence method to match the geometric extremities of two shapes which are partially isometric. We consider the most general setting of the isometric partial shape correspondence problem, in which ...

    • Photon Differential Splatting for Rendering Caustics 

      Frisvad, Jeppe Revall; Schjøth, Lars; Erleben, Kenny; Sporring, Jon (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a photon splatting technique which reduces noise and blur in the rendering of caustics. Blurring of illumination edges is an inherent problem in photon splatting, as each photon is unaware of its neighbours when ...

    • Procedural Modelling of Urban Road Networks 

      Bene , Jan; Wilkie, Alexander; Krivánek, Jaroslav (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a model for growing procedural road networks in and close to cities. The main idea of our paper is that a city cannot be meaningfully simulated without taking its neighbourhood into account. A simple traffic ...

    • Robust Detection and Segmentation for Diagnosis of Vertebral Diseases Using Routine MR Images 

      Zukic, D enan; Vlasák, Ale; Egger, Jan; Horínek, Daniel; Nimsky, Christopher; Kolb, Andreas (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      The diagnosis of certain spine pathologies, such as scoliosis, spondylolisthesis and vertebral fractures, is part of the daily clinical routine. Very frequently, magnetic resonance image data are used to diagnose these ...

    • Robust Treatment of Degenerate Elements in Interactive Corotational FEM Simulations 

      Civit-Flores, O.; Susín, A. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We address the problem of robust and efficient treatment of element collapse and inversion in corotational FEM simulations of deformable objects in two and three dimensions, and show that existing degeneration treatment ...

    • SATO: Surface Area Traversal Order for Shadow Ray Tracing 

      Nah, Jae-Ho; Manocha, Dinesh (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present the surface area traversal order (SATO) metric to accelerate shadow ray traversal. Our formulation uses the surface area of each child node to compute the TO. In this metric, we give a traversal priority to the ...

    • State-of-the-Art in Compressed GPU-Based Direct Volume Rendering 

      Rodríguez, M. Balsa; Gobbetti, E.; Guitián, J.A. Iglesias; Makhinya, M.; Marton, F.; Pajarola, R.; Suter, S.K. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Great advancements in commodity graphics hardware have favoured graphics processing unit (GPU)-based volume rendering as the main adopted solution for interactive exploration of rectilinear scalar volumes on commodity ...
