The Beam Radiance Estimate for Volumetric Photon Mapping
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a new method for efficiently simulating the scattering of light within participating media. Using a theoretical reformulation of volumetric photon mapping, we develop a novel photon gathering technique for ... -
Characterization for High Dynamic Range Imaging
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper we present a new practical camera characterization technique to improve color accuracy in high dynamic range (HDR) imaging. Camera characterization refers to the process of mapping device-dependent signals, ... -
CHC++: Coherent Hierarchical Culling Revisited
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a new algorithm for efficient occlusion culling using hardware occlusion queries. The algorithm significantly improves on previous techniques by making better use of temporal and spatial coherence of visibility. ... -
Conformal Flattening by Curvature Prescription and Metric Scaling
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present an efficient method to conformally parameterize 3D mesh data sets to the plane. The idea behind our method is to concentrate all the 3D curvature at a small number of select mesh vertices, called cone singularities, ... -
Curvature-Domain Shape Processing
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We propose a framework for 3D geometry processing that provides direct access to surface curvature to facilitate advanced shape editing, filtering, and synthesis algorithms. The central idea is to map a given surface to ... -
Deep Opacity Maps
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a new method for rapidly computing shadows from semi-transparent objects like hair. Our deep opacity maps method extends the concept of opacity shadow maps by using a depth map to obtain a per pixel distribution ... -
Detail-In-Context Visualization for Satellite Imagery
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We use the complex logarithm as a transformation for the visualization and navigation of highly complex satellite and aerial imagery. The resulting depictions show details and context with greatly different scales in one ... -
Distortion-Free Steganography for Polygonal Meshes
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a technique for steganography in polygonal meshes. Our method hides a message in the indexed rep-resentation of a mesh by permuting the order in which faces and vertices are stored. The permutation is relative ... -
Dynamic Sampling and Rendering of Algebraic Point Set Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Algebraic Point Set Surfaces (APSS) define a smooth surface from a set of points using local moving least-squares (MLS) fitting of algebraic spheres. In this paper we first revisit the spherical fitting problem and provide ... -
Effect of Character Animacy and Preparatory Motion on Perceptual Magnitude of Errors in Ballistic Motion
(The Eurographics Association and Blackwell Publishing Ltd, 2008)An increasing number of projects have examined the perceptual magnitude of visible artifacts in animated motion. These studies have been performed using a mix of character types, from detailed human models to abstract ... -
Efficient and Dynamic Simplification of Line Drawings
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper we present a pipeline for rendering dynamic 2D/3D line drawings efficiently. Our main goal is to create efficient static renditions and coherent animations of line drawings in a setting where lines can be ... -
An Example-based Procedural System for Element Arrangement
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a method for synthesizing two dimensional (2D) element arrangements from an example. The main idea is to combine texture synthesis techniques based-on a local neighborhood comparison and procedural modeling ... -
Expressive Facial Gestures From Motion Capture Data
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Human facial gestures often exhibit such natural stochastic variations as how often the eyes blink, how often the eyebrows and the nose twitch, and how the head moves while speaking. The stochastic movements of facial ... -
Fast Force Field Approximation and its Application to Skeletonization of Discrete 3D Objects
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper we present a novel method to approximate the force field of a discrete 3d object with a time complexity that is linear in the number of voxels. We define a rule, similar to the distance transform, to propagate ... -
A Fast Simulation Method Using Overlapping Grids for Interactions between Smoke and Rigid Objects
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Recently, many techniques using computational fluid dynamics have been proposed for the simulation of natural phenomena such as smoke and fire. Traditionally, a single grid is used for computing the motion of fluids. When ... -
Floating Textures
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a novel multi-view, projective texture mapping technique. While previous multi-view texturing approaches lead to blurring and ghosting artefacts if 3D geometry and/or camera calibration are imprecise, we propose ... -
Fluid in Video: Augmenting Real Video with Simulated Fluids
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a technique for coupling simulated fluid phenomena that interact with real dynamic scenes captured as a binocular video sequence. We first process the binocular video sequence to obtain a complete 3D reconstruction ... -
Frontmatter

GPU Accelerated Direct Volume Rendering on an Interactive Light Field Display
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a GPU accelerated volume ray casting system interactively driving a multi-user light field display. The display, driven by a single programmable GPU, is based on a specially arranged array of projectors and a ... -
GPU-based Fast Ray Casting for a Large Number of Metaballs
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Metaballs are implicit surfaces widely used to model curved objects, represented by the isosurface of a density field defined by a set of points. Recently, the results of particle-based simulations have been often visualized ...
