Inexpensive Reconstruction and Rendering of Realistic Roadside Landscapes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)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 ... -
Greedy Geometric Algorithms for Collection of Balls, with Applications to Geometric Approximation and Molecular Coarse-Graining
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Choosing balls that best approximate a 3D object is a non-trivial problem. To answer it, we first address the inner approximation problem, which consists of approximating an object FO defined by a union of n balls with k ... -
Procedural Modelling of Urban Road Networks
(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 ... -
A Survey on Procedural Modelling for Virtual Worlds
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Procedural modelling deals with (semi-)automatic content generation by means of a program or procedure. Among other advantages, its data compression and the potential to generate a large variety of detailed content with ... -
A Weighted Delaunay Triangulation Framework for Merging Triangulations in a Connectivity Oblivious Fashion
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Simplicial meshes are useful as discrete approximations of continuous spaces in numerical simulations. In some applications, however, meshes need to be modified over time. Mesh update operations are often expensive and ... -
Inherent Noise-Aware Insect Swarm Simulation
(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 ... -
Distributed Out-of-Core Stochastic Progressive Photon Mapping
(The Eurographics Association and John Wiley and Sons Ltd., 2014)At present, stochastic progressive photon mapping (SPPM) is one of the most comprehensive methods for a consistent global illumination computation. Even though the number of photons is unlimited due to their progressive ... -
Continuous Self-Collision Detection for Deformable Surfaces Interacting with Solid Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we propose a new continuous self-collision detection (CSCD) method for a deformable surface that interacts with a simple solid model. The method is developed based on the radial-view-based culling method. ... -
Partial 3-D Correspondence from Shape Extremities
(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 ... -
SATO: Surface Area Traversal Order for Shadow Ray Tracing
(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 ... -
Inverse Procedural Modelling of Trees
(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 ... -
Flux-Limited Diffusion for Multiple Scattering in Participating Media
(The Eurographics Association and John Wiley and Sons Ltd., 2014)For the rendering of multiple scattering effects in participating media, methods based on the diffusion approximation are an extremely efficient alternative to Monte Carlo path tracing. However, in sufficiently transparent ... -
Robust Detection and Segmentation for Diagnosis of Vertebral Diseases Using Routine MR Images
(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 ... -
Symmetry-Aware Template Deformation and Fitting
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we propose a new method for reconstructing 3D models from a noisy and incomplete 3D scan and a coarse template model. The main idea is to maintain characteristic high-level features of the template that ... -
Out-of-Core Construction of Sparse Voxel Octrees
(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 ... -
Photon Differential Splatting for Rendering Caustics
(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 ... -
GEARS: A General and Efficient Algorithm for Rendering Shadows
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a soft shadow rendering algorithm that is general, efficient and accurate. The algorithm supports fully dynamic scenes, with moving and deforming blockers and receivers, and with changing area light source ... -
Continuous Levels-of-Detail and Visual Abstraction for Seamless Molecular Visualization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Molecular visualization is often challenged with rendering of large molecular structures in real time. We introduce a novel approach that enables us to show even large protein complexes. Our method is based on the ... -
Modelling Cumulus Cloud Shape from a Single Image
(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 ... -
Robust Treatment of Degenerate Elements in Interactive Corotational FEM Simulations
(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 ...
