Easy Matting - A Stroke Based Approach for Continuous Image Matting
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We propose an iterative energy minimization framework for interactive image matting. Our approach is easy in the sense that it is fast and requires only few user-specified strokes for marking the foreground and background. ... -
Easy Mesh Cutting
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We present Easy Mesh Cutting, an intuitive and easy-to-use mesh cutout tool. Users can cut meaningful components from meshes by simply drawing freehand sketches on the mesh. Our system provides instant visual feedback to ... -
Efficient Large Scale Acquisition of Building Interiors
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We describe a system for the rapid acquisition of building interiors. In 40 hours, a two member team with a single acquisition device captured a model of the corridors and 20 individual rooms spanning 6 floors of a large ... -
Enhancing the Interactive Visualization of Procedurally Encoded Multifield Data with Ellipsoidal Basis Functions
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Functional approximation of scattered data is a popular technique for compactly representing various types of datasets in computer graphics, including surface, volume, and vector datasets. Typically, sums of Gaussians or ... -
GPU-based Collision Detection for Deformable Parameterized Surfaces
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Based on the potential of current programmable GPUs, recently several approaches were developed that use the GPU to calculate deformations of surfaces like the folding of cloth or to convert higher level geometry to ... -
Implicit Surface Modelling with a Globally Regularised Basis of Compact Support
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We consider the problem of constructing a globally smooth analytic function that represents a surface implicitly by way of its zero set, given sample points with surface normal vectors.The contributions of the paper include ... -
An Improved Physically-Based Soft Shadow Volume Algorithm
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We identify and analyze several performance problems in a state-of-the-art physically-based soft shadow volume algorithm, and present an improved method that alleviates these problems by replacing an overly conservative ... -
Latent Doodle Space
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We propose the concept of a latent doodle space, a low-dimensional space derived from a set of input doodles, or simple line drawings. The latent space provides a foundation for generating new drawings that are similar, ... -
Multiresolution Random Accessible Mesh Compression
(The Eurographics Association and Blackwell Publishing, Inc, 2006)This paper presents a novel approach for mesh compression, which we call multiresolution random accessible mesh compression. In contrast to previous mesh compression techniques, the approach enables us to progressively ... -
Opacity Peeling for Direct Volume Rendering
(The Eurographics Association and Blackwell Publishing, Inc, 2006)The most important technique to visualize 3D scalar data, as they arise e.g. in medicine from tomographic measurement, is direct volume rendering. A transfer function maps the scalar values to optical properties which are ... -
Optimizing Control Variate Estimators for Rendering
(The Eurographics Association and Blackwell Publishing, Inc, 2006) -
A Predictive Light Transport Model for the Human Iris
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Recently, light interactions with organic matter have become the object of detailed investigations by image synthesis researchers. Besides allowing these materials to be rendered in a more intuitive manner, these efforts ... -
Preface

A Primer on Topological Persistence
(The Eurographics Association and Blackwell Publishing, Inc, 2006)The idea of topological persistence is to look at homological features that persist along a nested sequence of topo-logical spaces. As a typical example, we may take the sequence of sublevel sets of a function. The ... -
Projective Alpha Colour
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Alpha colours were introduced for image compositing, using a pixel coverage model. Algebraically they resemble homogeneous coordinates, widely used in projective geometry calculations. We show why this is the case. This ... -
Ray Tracing Animated Scenes using Motion Decomposition
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Though ray tracing has recently become interactive, its high precomputation time for building spatial indices usually limits its applications to walkthroughs of static scenes. This is a major limitation, as most applications ... -
Real-Time Weighted Pose-Space Deformation on the GPU
(The Eurographics Association and Blackwell Publishing, Inc, 2006)WPSD (Weighted Pose Space Deformation) is an example based skinning method for articulated body animation. The per-vertex computation required in WPSD can be parallelized in a SIMD (Single Instruction Multiple Data) manner ... -
Reflected-Scene Impostors for Realistic Reflections at Interactive Rates
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We present a technique for rendering reflections on complex reflectors at interactive rates based on approximating the geometry of the reflected scene with impostors. The reflections correctly convey the distance to the ... -
A Robust Two-Step Procedure for Quad-Dominant Remeshing
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We propose a new technique for quad-dominant remeshing which separates the local regularity requirements from the global alignment requirements by working in two steps. In the first step, we apply a slight variant of ... -
Seamless Integration of Initial Sketching and Subsequent Detail Editing in Flower Modeling
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We present an interactive modeling system for flower composition that supports seamless transformation from an initial sketch to a detailed three-dimensional (3D) model. To begin, the user quickly sketches the overall ...
