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 ... -
Semantic Photo Synthesis
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Composite images are synthesized from existing photographs by artists who make concept art, e.g., storyboards for movies or architectural planning. Current techniques allow an artist to fabricate such an image by digitally ... -
Silhouette Extraction in Hough Space
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Object-space silhouette extraction is an important problem in fields ranging from non-photorealistic computer graphics to medical robotics. We present an efficient silhouette extractor for triangle meshes under perspective ... -
Splicing Upper-Body Actions with Locomotion
(The Eurographics Association and Blackwell Publishing, Inc, 2006)This paper presents a simple and efficient technique for synthesizing high-fidelity motions by attaching, or splicing, the upper-body action of one motion example to the lower-body locomotion of another. Existing splicing ... -
Stroke Pattern Analysis and Synthesis
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We present a synthesis technique that can automatically generate stroke patterns based on a user-specified reference pattern. Our method is an extension of texture synthesis techniques to vector-based patterns. Such an ...
