Decomposition and Visualization of Fourth-Order Elastic-Plastic Tensors
(The Eurographics Association, 2008)Visualization of fourth-order tensors from solid mechanics has not been explored in depth previously. Challenges include the large number of components (3x3x3x3 for 3D), loss of major symmetry and loss of positive definiteness ... -
GPU-based Particle Systems for Illustrative Volume Rendering
(The Eurographics Association, 2008)Illustrative techniques are generally applied to produce stylized renderings. Various illustrative styles have been applied to volumetric data sets, producing clearer images and effectively conveying visual information. ... -
A Graph-Based Approach to Symmetry Detection
(The Eurographics Association, 2008)Symmetry detection aims at discovering redundancy in the form of reoccurring structures in geometric objects. In this paper, we present a new symmetry detection algorithm for geometry represented as point clouds that is ... -
Harmonic Colormaps for Volume Visualization
(The Eurographics Association, 2008)Color design forms a crucial part in visual aesthetics, and it has been shown that a visually aesthetic visualization will be looked at more carefully. An important role plays here the choice of a colormap that is composed ... -
Interactive Global Light Propagation in Direct Volume Rendering using Local Piecewise Integration
(The Eurographics Association, 2008)A novel technique for efficient computation of global light propagation in interactive DVR is presented in this paper. The approach is based on a combination of local shadows from the vicinity of each voxel with global ... -
Isosurface Ambient Occlusion and Soft Shadows with Filterable Occlusion Maps
(The Eurographics Association, 2008)Volumetric data sets are often examined by displaying isosurfaces, surfaces where the data or function takes on a given value. We propose a new method for rendering isosurfaces at interactive rates while supporting dynamic ... -
Layers for Effective Volume Rendering
(The Eurographics Association, 2008)A multi-layer volume rendering framework is presented. The final image is obtained by compositing a number of renderings, each being represented as a separate layer. This layer-centric framework provides a rich set of 2D ... -
Memory Efficient GPU-Based Ray Casting for Unstructured Volume Rendering
(The Eurographics Association, 2008)Volume ray casting algorithms benefit greatly with recent increase of GPU capabilities and power. In this paper, we present a novel memory efficient ray casting algorithm for unstructured grids completely implemented on ... -
Multiresolution Interval Volume Meshes
(The Eurographics Association, 2008)Interval volumes are a generalization of isosurfaces that represent the set of points between two surfaces. In this paper, we present a compact multi-resolution representation for interval volume meshes extracted from ... -
Obscurance-based Volume Rendering Framework
(The Eurographics Association, 2008)Obscurances, from which ambient occlusion is a particular case, is a technology that produces natural-looking lighting effects in a faster way than global illumination. Its application in volume visualization is of special ... -
On Accuracy of Marching Isosurfacing Methods
(The Eurographics Association, 2008)Representational accuracy of the isosurface meshes produced by well-known marching isosurfacing methods is considered. Accuracy is determined versus the isosurface given by trilinear interpolation and quantified using a ... -
Parallel Construction of k-Nearest Neighbor Graphs for Point Clouds
(The Eurographics Association, 2008)We present a parallel algorithm for k-nearest neighbor graph construction that uses Morton ordering. Experiments show that our approach has the following advantages over existing methods: (1) Faster construction of k-nearest ... -
Pre-Integrated Volume Rendering for Multi-Dimensional Transfer Functions
(The Eurographics Association, 2008)This work presents an efficient extension of pre-integrated volume rendering for multi-dimensional transfer functions. Since even two-dimensional transfer functions can result in strong rendering artifacts that cannot be ... -
Pseudorandom Noise for Real-Time Volumetric Rendering of Fire in a Production System
(The Eurographics Association, 2008)This paper presents an effort at developing a robust, interactive framework for rendering 3D fire in real-time in a production environment. Many techniques of rendering fire in non real-time exist and are constantly employed ... -
Smooth Mixed-Resolution GPU Volume Rendering
(The Eurographics Association, 2008)We propose a mixed-resolution volume ray-casting approach that enables more flexibility in the choice of downsampling positions and filter kernels, allows freely mixing volume bricks of different resolutions during rendering, ... -
Stereo Pseudo 3D Rendering for Web-based Display of Scientific Volumetric Data
(The Eurographics Association, 2008)Advancement in high-throughput microscopy technology such as the Knife-Edge Scanning Microscopy (KESM) is enabling the production of massive amounts of high-resolution volumetric data of biological microstructures. To fully ... -
Stroke-Based Transfer Function Design
(The Eurographics Association, 2008)In this paper we propose a user interface for the design of 1D transfer functions. The user can select a feature of interest by drawing one or more strokes directly onto the volume rendering near its silhouette. Based on ... -
A Survey of Methods for Moving Least Squares Surfaces
(The Eurographics Association, 2008)Moving least squares (MLS) surfaces representation directly defines smooth surfaces from point cloud data, on which the differential geometric properties of point set can be conveniently estimated. Nowadays, the MLS surfaces ...
