Part-type Segmentation of Articulated Voxel-Shapes using the Junction Rule
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a part-type segmentation method for articulated voxel-shapes based on curve skeletons. Shapes are considered to consist of several simpler, intersecting shapes. Our method is based on the junction rule: the ... -
Particle Level Set Advection for the Interactive Visualization of Unsteady 3D Flow
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Typically, flow volumes are visualized by defining their boundary as iso-surface of a level set function. Grid-based level sets offer a good global representation but suffer from numerical diffusion of surface detail, ... -
Patch-type Segmentation of Voxel Shapes using Simplified Surface Skeletons
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a new method for decomposing a 3D voxel shape into disjoint segments using the shape s simplified surface-skeleton. The surface skeleton of a shape consists of 2D manifolds inside its volume. Each skeleton point ... -
Peek-in-the-Pic: Flying Through Architectural Scenes From a Single Image*
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Many casually taken tourist photographs comprise of architectural objects like houses, buildings, etc. Reconstructing such 3D scenes captured in a single photograph is a very challenging problem. We propose a novel ... -
Perceptual Evaluation of Color-to-Grayscale Image Conversions
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Color images often have to be converted to grayscale for reproduction, artistic purposes, or for subsequent processing. Methods performing the conversion of color images to grayscale aim to retain as much information about ... -
Photo-realistic Rendering of Metallic Car Paint from Image-Based Measurements
(The Eurographics Association and Blackwell Publishing Ltd, 2008)State-of-the-art car paint shows not only interesting and subtle angular dependency but also significant spatial variation. Especially in sunlight these variations remain visible even for distances up to a few meters and ... -
Photon-driven Irradiance Cache
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We describe a global illumination method combining two well known techniques: photon mapping and irradiance caching. The photon mapping method has the advantage of being view independent but requires a costly additional ... -
Physically-based Dye Advection for Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Dye advection is widely used in experimental flow analysis but has seen less use for visualization in computational fluid dynamics. One possible reason for this disconnect is the inaccuracy of the texture-based approach, ... -
Point-Based Rendering of Non-Manifold Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We are concerned with producing high-quality images of parametric and implicit surfaces, in particular those with non-manifold features. We present a point-based technique for rendering implicit surfaces that uses octree ... -
Pointwise radial minimization: Hermite interpolation on arbitrary domains
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper we propose a new kind of Hermite interpolation on arbitrary domains, matching derivative data of arbitrary order on the boundary. The basic idea stems from an interpretation of mean value interpolation as the ... -
Polyhedral Finite Elements Using Harmonic Basis Functions
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Finite element simulations in computer graphics are typically based on tetrahedral or hexahedral elements, which enables simple and efficient implementations, but in turn requires complicated remeshing in case of topological ... -
Practical HDR Texture Compression
(The Eurographics Association and Blackwell Publishing Ltd, 2008)The use of high dynamic range (HDR) textures in real-time graphics applications can increase realism and provide a more vivid experience. However, the increased bandwidth and storage requirements for uncompressed HDR data ... -
Practical Product Importance Sampling for Direct Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a practical algorithm for sampling the product of environment map lighting and surface reflectance. Our method builds on wavelet-based importance sampling, but has a number of important advantages over previous ... -
Precomputed Atmospheric Scattering
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a new and accurate method to render the atmosphere in real time from any viewpoint from ground level to outer space, while taking Rayleigh and Mie multiple scattering into account. Our method reproduces many ... -

Pressing: Smooth Isosurfaces with Flats from Binary Grids
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We explore the automatic recovery of solids from their binary volumetric discretizations. In particular, we propose an approach, called Pressing, for smoothing isosurfaces extracted from binary volumes while recovering ... -
A Prism-Free Method for Silhouette Rendering in Inverse Displacement Mapping
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Silhouette is a key feature that distinguishes displacement mapping from normal mapping. However the silhouette rendering in the GPU implementation of displacement mapping (which is often called inversed displacement ... -
Progressive Interpolation based on Catmull-Clark Subdivision Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We introduce a scheme for constructing a Catmull-Clark subdivision surface that interpolates the vertices of a quadrilateral mesh with arbitrary topology. The basic idea here is to progressively modify the vertices of an ...
