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 ...
