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 ... -
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, ... -
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 ... -
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 ... -
C-BDAM - Compressed Batched Dynamic Adaptive Meshes for Terrain Rendering
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We describe a compressed multiresolution representation for supporting interactive rendering of very large planar and spherical terrain surfaces. The technique, called Compressed Batched Dynamic Adaptive Meshes (C-BDAM), ... -
Cache-Efficient Layouts of Bounding Volume Hierarchies
(The Eurographics Association and Blackwell Publishing, Inc, 2006) -
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 ... -
Computing discrete shape operators on general meshes
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Discrete curvature and shape operators, which capture complete information about directional curvatures at a point, are essential in a variety of applications: simulation of deformable two-dimensional objects, variational ... -
Creating Face Models from Vague Mental Images
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We present a novel approach to create plausible 3D face models from vague recollections or incomplete descriptions. This task plays an important role in police work, where composite facial images of suspects need to be ... -
Cross Dissolve Without Cross Fade: Preserving Contrast, Color and Salience in Image Compositing
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Linear interpolation is the standard image blending method used in image compositing. By averaging in the dynamic range, it reduces contrast and visibly degrades the quality of composite imagery. We demonstrate how to ... -
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 ... -
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 ... -
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 ... -
Direct (Re)Meshing for Efficient Surface Processing
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We propose a novel surface remeshing algorithm. While many remeshing algorithms are based on global parametrization or local mesh optimization, our algorithm is closely related to surface reconstruction techniques and it ... -
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 ...
