Condenser-Based Instant Reflectometry
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a technique for rapid capture of high quality bidirectional reflection distribution functions(BRDFs) of surface points. Our method represents the BRDF at each point by a generalized microfacet model with tabulated ... -
Context-Dependent Crowd Evaluation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Many times, even if a crowd simulation looks good in general, there could be some specific individual behaviors which do not seem correct. Spotting such problems manually can become tedious, but ignoring them may harm the ... -
Contour-based Interface for Refining Volume Segmentation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Medical volume images contain ambiguous and low-contrast boundaries around which existing fully- or semiautomatic segmentation algorithms often cause errors. In this paper, we propose a novel system for intuitively and ... -
Creating and Preserving Vortical Details in SPH Fluid
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a new method to create and preserve the turbulent details generated around moving objects in SPH fluid. In our approach, a high-resolution overlapping grid is bounded to each object and translates with the object. ... -
Density-based Outlier Rejection in Monte Carlo Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2010)The problem of noise in Monte-Carlo rendering arising from estimator variance is well-known and well-studied. In this work, we concentrate on identifying individual light paths as outliers that lead to significant spikes ... -
Dirichlet Harmonic Shape Compression with Feature Preservation for Parameterized Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2010)With the rapid advancement of 3D scanning devices, large and complicated 3D shapes are becoming ubiquitous, and require large amount of resources to store and transmit them efficiently. This makes shape compression a ... -
Efficient Mean-shift Clustering Using Gaussian KD-Tree
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Mean shift is a popular approach for data clustering, however, the high computational complexity of the mean shift procedure limits its practical applications in high dimensional and large data set clustering. In this ... -
An Example-based Approach to Synthesize Artistic Strokes using Graphs
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper, we propose a technique to produce artistic strokes in a variety of drawing material based on example images. Our approach is to divide example strokes scanned from images into small pieces along their stroke ... -
Fast Particle-based Visual Simulation of Ice Melting
(The Eurographics Association and Blackwell Publishing Ltd, 2010)The visual simulation of natural phenomena has been widely studied. Although several methods have been proposed to simulate melting, the flows of meltwater drops on the surfaces of objects are not taken into account. In ... -
Fast Updating of Delaunay Triangulation of Moving Points by Bi-cell Filtering
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Updating a Delaunay triangulation when data points are slightly moved is the bottleneck of computation time in variational methods for mesh generation and remeshing. Utilizing the connectivity coherence between two consecutive ... -
Feature based terrain generation using diffusion equation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)This paper presents a diffusion method for generating terrains from a set of parameterized curves that characterize the landform features such as ridge lines, riverbeds or cliffs. Our approach provides the user with an ... -
Feature Oriented Progressive Lossless Mesh Coding
(The Eurographics Association and Blackwell Publishing Ltd, 2010)A feature-oriented generic progressive lossless mesh coder (FOLProM) is proposed to encode triangular meshes with arbitrarily complex geometry and topology. In this work, a sequence of levels of detail (LODs) are generated ... -

Image Synthesis for Branching Structures
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a set of techniques for the synthesis of artificial images that depict branching structures like rivers, cracks, lightning, mountain ranges, or blood vessels. The central idea is to build a statistical model ... -
Instant Propagation of Sparse Edits on Images and Videos
(The Eurographics Association and Blackwell Publishing Ltd, 2010)The ability to quickly and intuitively edit digital contents has become increasingly important in our everyday life. We propose a novel method for propagating a sparse set of user edits (e.g., changes in color, brightness, ... -
L4RW: Laziness-based Realistic Real-time Responsive Rebalance in Walking
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a novel L4RW (Laziness-based Realistic Real-time Responsive Rebalance in Walking) technique to synthesize 4RW animations under unexpected external perturbations with minimal locomotion effort. We first devise a ... -
Least Squares Subdivision Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2010)The usual approach to design subdivision schemes for curves and surfaces basically consists in combining proper rules for regular configurations, with some specific heuristics to handle extraordinary vertices. In this ... -
Manifold-Based 3D Face Caricature Generation with Individualized Facial Feature Extraction
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Caricature is an interesting art to express exaggerated views of different persons and things through drawing. The face caricature is popular and widely used for different applications. To do this, we have to properly ... -
Metalights: Improved Interleaved Shading
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present metalights, a novel Virtual Point Light (VPL) encapsulating structure which enhances classic interleaved shading by improving VPL sampling, based on few initial screen space samples to estimate VPL contribution ... -
Modeling Complex Unfoliaged Trees from a Sparse Set of Images
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a novel image-based technique for modeling complex unfoliaged trees. Existing tree modeling tools either require capturing a large number of views for dense 3D reconstruction or rely on user inputs and botanic ...
