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 ... -
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 ... -
Tuning Subdivision by Minimising Gaussian Curvature Variation Near Extraordinary Vertices
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We present a method for tuning primal stationary subdivision schemes to give the best possible behaviour near extraordinary vertices with respect to curvature variation.Current schemes lead to a limit surface around ... -
Towards a Unified Dynamical Solver for Computer Graphics
(The Eurographics Association and Blackwell Publishing, Inc, 2006)In this talk I will present some research I have done over the past few years in developing a unified dynamical solver for computer graphics. Currently many solvers are specialized for a given phenomenon such as fluid flow, ... -
Data Preparation for Real-time High Quality Rendering of Complex Models
(The Eurographics Association and Blackwell Publishing, Inc, 2006)The capability of current 3D acquisition systems to digitize the geometry reflection behaviour of objects as well as the sophisticated application of CAD techniques lead to rapidly growing digital models which pose new ... -
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 ... -
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 ... -
Accurate Specular Reflections in Real-Time
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Specular reflections provide many important visual cues in our daily environment. They inform us of the shape of objects, of the material they are made of, of their relative positions, etc. Specular reflections on curved ... -
Bayesian Point Cloud Reconstruction
(The Eurographics Association and Blackwell Publishing, Inc, 2006)In this paper, we propose a novel surface reconstruction technique based on Bayesian statistics: The measurement process as well as prior assumptions on the measured objects are modeled as probability distributions and ... -
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 ... -
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 ... -
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 ... -
Data-driven Local Coordinate Systems for Image-Based Rendering
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Image-based representations of an object profit from known geometry. The more accurate this geometry is known, the better corresponding pixels in the different images can be aligned, which leads to less artifacts and better ... -
Competing Fronts for Coarse-to-Fine Surface Reconstruction
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We present a deformable model to reconstruct a surface from a point cloud. The model is based on an explicit mesh representation composed of multiple competing evolving fronts. These fronts adapt to the local feature size ... -
Texture Adaptation for Progressive Meshes
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Level-of-detail modeling is a vital representation for real-time applications. To support texture mapping progressive meshes (PM), we usually allow the whole PM sequence to share a common texture map. Although such a common ... -
Optimizing Control Variate Estimators for Rendering
(The Eurographics Association and Blackwell Publishing, Inc, 2006) -
Analysis of Reproducing Real-World Appearance on Displays of Varying Dynamic Range
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We conduct a series of experiments to investigate the desired properties of a tone mapping operator (TMO) and to design such an operator based on subjective data. We propose a novel approach to the tone mapping problem, ... -
Beyond Tone Mapping: Enhanced Depiction of Tone Mapped HDR Images
(The Eurographics Association and Blackwell Publishing, Inc, 2006)High Dynamic Range (HDR) images capture the full range of luminance present in real world scenes, and unlike Low Dynamic Range (LDR) images, can simultaneously contain detailed information in the deepest of shadows and the ... -
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, ... -
Dancing-to-Music Character Animation
(The Eurographics Association and Blackwell Publishing, Inc, 2006)In computer graphics, considerable research has been conducted on realistic human motion synthesis. However, most research does not consider human emotional aspects, which often strongly affect human motion. This paper ...
