On Neighbourhood Matching for Texture-by-Numbers
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Texture-by-Numbers is an attractive texture synthesis framework, because it is able to cope with non-homogeneous texture exemplars, and provides the user with intuitive creative control over the outcome of the synthesis ... -
Taylor Prediction for Mesh Geometry Compression
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In this paper, we introduce a new formalism for mesh geometry prediction. We derive a class of smooth linear predictors from a simple approach based on the Taylor expansion of the mesh geometry function. We use this method ... -
Allometric Scaling for Character Design
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Geometric scaling transformations do not respect the biological processes which govern the size and shape of living creatures. In this paper, we describe an approach to scaling which can be related to biological function. ... -
A Survey of Real-Time Hard Shadow Mapping Methods
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Because of its versatility, speed and robustness, shadow mapping has always been a popular algorithm for fast hard shadow generation since its introduction in 1978, first for offline film productions and later increasingly ... -
Hermite Radial Basis Functions Implicits
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The Hermite radial basis functions (HRBF) implicits reconstruct an implicit function which interpolates or approximates scattered multivariate Hermite data (i.e. unstructured points and their corresponding normals). ... -
Using VisTrails and Provenance for Teaching Scientific Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Over the last 20 years, visualization courses have been developed and offered at universities around the world. Many of these courses use established visualization libraries and tools (e.g. VTK, ParaView, AVS, VisIt) as a ... -
Experimental Feedback on Prog and Play: A Serious Game for Programming Practice
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents an experimental feedback on a serious game dedicated to strengthening programming skills. This serious game, called Prog&Play, is built on an open source real-time strategy game. Its goal is to be ... -
A Survey of Ocean Simulation and Rendering Techniques in Computer Graphics
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents a survey of ocean simulation and rendering methods in computer graphics. To model and animate the ocean’s surface, these methods mainly rely on two main approaches: on the one hand, those which approximate ... -

Free Path Sampling in High Resolution Inhomogeneous Participating Media
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents efficient algorithms for free path sampling in heterogeneous participating media defined either by high-resolution voxel arrays or generated procedurally. The method is based on the concept of mixing ... -
A Parallel SPH Implementation on Multi-Core CPUs
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents a parallel framework for simulating fluids with the Smoothed Particle Hydrodynamics (SPH) method. For low computational costs per simulation step, efficient parallel neighbourhood queries are proposed ... -
CheckViz: Sanity Check and Topological Clues for Linear and Non-Linear Mappings
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Multidimensional scaling is a must-have tool for visual data miners, projecting multidimensional data onto a two-dimensional plane. However, what we see is not necessarily what we think about. In many cases, end-users do ... -
Flexible and Accurate Transparent - Object Matting and Compositing Using Refractive Vector Field
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In digital image editing, environment matting and compositing are fundamental and interesting operations that can capture and simulate the refraction and reflection effects of light from an environment. The state‐of‐the‐art ... -
Toward Optimal Space Partitioning for Unbiased, Adaptive Free Path Sampling of Inhomogeneous Participating Media
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Photo-realistic rendering of inhomogeneous participating media with light scattering in consideration is impor- tant in computer graphics, and is typically computed using Monte Carlo based methods. The key technique in ... -
Interactive Indirect Illumination Using Voxel Cone Tracing
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Indirect illumination is an important element for realistic image synthesis, but its computation is expensive and highly dependent on the complexity of the scene and of the BRDF of the involved surfaces. While off-line ... -
Improving Performance and Accuracy of Local PCA
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Local Principal Component Analysis (LPCA) is one of the popular techniques for dimensionality reduction and data compression of large data sets encountered in computer graphics. The LPCA algorithm is a variant of kmeans ... -
A Graph-based Approach to Continuous Line Illustrations with Variable Levels of Detail
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper introduces a method for automatically generating continuous line illustrations, drawings consisting of a single line, from a given input image. Our approach begins by inferring a graph from a set of edges extracted ... -
Rephotography Using Image Collections
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper proposes a novel system that 'rephotographs' a historical photograph with a collection of images. Rather than finding the accurate viewpoint of the historical photo, users only need to take a number of photographs ... -
An Illustrative Visualization Framework for 3D Vector Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Most 3D vector field visualization techniques suffer from the problem of visual clutter, and it remains a challenging task to effectively convey both directional and structural information of 3D vector fields. In this ... -
Creating Fluid Animation from a Single Image using Video Database
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a method for synthesizing fluid animation from a single image, using a fluid video database. The user inputs a target painting or photograph of a fluid scene along with its alpha matte that extracts the fluid ...
