32nd EUROGRAPHICS General Assembly
(The Eurographics Association and Blackwell Publishing Ltd., 2011) -
Computational Aesthetics 2011 in Vancouver, Canada, August 5–7, 2011, Sponsored by Eurographics, in Collaboration with ACM SIGGRAPH
(The Eurographics Association and Blackwell Publishing Ltd., 2011) -
Computational Plenoptic Imaging
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The plenoptic function is a ray‐based model for light that includes the colour spectrum as well as spatial, temporal and directional variation. Although digital light sensors have greatly evolved in the last years, one ... -
Context‐Based Coding of Adaptive Multiresolution Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Multiresolution meshes provide an efficient and structured representation of geometric objects. To increase the mesh resolution only at vital parts of the object, adaptive refinement is widely used. We propose a lossless ... -
Convolution‐Based Simulation of Homogeneous Subsurface Scattering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper introduces a new method for simulating homogeneous subsurface light transport in translucent objects. Our approach is based on irradiance convolutions over a multi‐layered representation of the volume for light ... -
Example‐Driven Deformations Based on Discrete Shells
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Despite the huge progress made in interactive physics‐based mesh deformation, manipulating a geometrically complex mesh or posing a detailed character is still a tedious and time‐consuming task. Example‐driven methods ... -
Finding Syntactic Structures from Human Motion Data
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a new approach to motion rearrangement that preserves the syntactic structures of an input motion automatically by learning a context‐free grammar from the motion data. For grammatical analysis, we reduce an ... -
A Flexible Approach for Output‐Sensitive Rendering of Animated Characters
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Rendering detailed animated characters is a major limiting factor in crowd simulation. In this paper we present a new representation for 3D animated characters which supports output‐sensitive rendering. Our approach is ... -
A General BRDF Representation Based on Tensor Decomposition
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Generating photo‐realistic images through Monte Carlo rendering requires efficient representation of light–surface interaction and techniques for importance sampling. Various models with good representation abilities have ... -
Hierarchical Deformation of Locally Rigid Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We propose a method for calculating deformations of models by deforming a low‐resolution mesh and adding details while ensuring that the details we add satisfy a set of constraints. Our method builds a low‐resolution ... -
Learning Boundary Edges for 3D‐Mesh Segmentation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents a 3D‐mesh segmentation algorithm based on a learning approach. A large database of manually segmented 3D‐meshes is used to learn a boundary edge function. The function is learned using a classifier which ... -
Making Imperfect Shadow Maps View‐Adaptive: High‐Quality Global Illumination in Large Dynamic Scenes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We propose an algorithm to compute interactive indirect illumination in dynamic scenes containing millions of triangles. It makes use of virtual point lights (VPL) to compute bounced illumination and a point‐based scene ... -
A New QEM for Parametrization of Raster Images
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present an image processing method that converts a raster image to a simplical two‐complex which has only a small number of vertices (base mesh) plus a parametrization that maps each pixel in the original image to a ... -
Non‐Linear Beam Tracing on a GPU
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Beam tracing combines the flexibility of ray tracing and the speed of polygon rasterization. However, beam tracing so far only handles linear transformations; thus, it is only applicable to linear effects such as planar ... -
An Optimal Control Approach for Texture Metamorphosis
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In this paper, we introduce a new texture metamorphosis approach for interpolating texture samples from a source texture into a target texture. We use a new energy optimization scheme derived from optimal control principles ... -
Perceptually Based Appearance Modification for Compliant Appearance Editing
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Projection‐based appearances are used in a variety of computer graphics applications to impart different appearances onto physical surfaces using digitally controlled projector light. To achieve a compliant appearance, all ... -
Pre‐computed Gathering of Multi‐Bounce Glossy Reflections
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Recent work in interactive global illumination addresses diffuse and moderately glossy indirect lighting effects, but high‐frequency effects such as multi‐bounce reflections on highly glossy surfaces are often ignored. ... -

Simplex and Diamond Hierarchies: Models and Applications
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Hierarchical spatial decompositions are a basic modelling tool in a variety of application domains. Several papers on this subject deal with hierarchical simplicial decompositions generated through regular simplex bisection. ... -
Social Network Clustering and Visualization using Hierarchical Edge Bundles
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The hierarchical edge bundle (HEB) method generates useful visualizations of dense graphs, such as social networks, but requires a predefined clustering hierarchy, and does not easily benefit from existing straight‐line ...
