A Survey of Specularity Removal Methods
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The separation of reflection components is an important issue in computer graphics, computer vision and image processing. It provides useful information for the applications that need consistent object surface appearance, ... -
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 ... -
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. ... -
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 ... -
Stroke Correspondence Construction Using Manifold Learning
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Stroke correspondence construction is a precondition for generating inbetween frames from a set of key frames. In our case, each stroke in a key frame is a vector represented as a Disk B‐Spline Curve (DBSC) which is a ... -
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 ... -
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 ... -
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 ... -
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 ... -
Visualizing Strain Anisotropy in Mantle Flow Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The evolution of strain and development of material anisotropy in models of the Earth’s mantle flow convey important information about how to interpret the geometric relationship between observation of seismic anisotropy ... -
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 ... -
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 ... -
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 ... -
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 ... -
Visualisation Techniques for Using Spatial Augmented Reality in the Design Process of a Car
(The Eurographics Association and Blackwell Publishing Ltd., 2011)If spatial augmented reality is used in the design process of a car, then one of the most important issues is that the virtual content is projected with a very high visual quality onto the real object, because based on ... -
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 ... -
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 ... -
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) -
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. ... -
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 ...
