Bent Normals and Cones in Screen-space
(The Eurographics Association, 2011)Ambient occlusion (AO) is a popular technique for real-time as well as offline rendering. One of its benefits is a gain in efficiency due to the fact that occlusion and shading are decoupled which results in an average ... -
A Cluster Hierarchy-based Volume Rendering Approach for Interactive Visual Exploration of Multi-variate Volume Data
(The Eurographics Association, 2011)Interactive visual analysis of volumetric data relies on intuitive, yet powerful mechanisms to generate transfer functions. For multi-variate data, traditional methods for interactive transfer functions generation are of ... -
A Clustering-based Visualization Technique to Emphasize Meaningful Regions of Vector Fields
(The Eurographics Association, 2011)This paper proposes a vector field visualization approach that extracts and visualizes grouped regions of static 3D vector fields of similar curvature behavior. These regions are argued to ease the recognition of regions ... -
Data-Driven Visualization of Functional Brain Regions from Resting State fMRI Data
(The Eurographics Association, 2011)Functional parcellation of the human cortex plays an important role in the understanding of brain functions. Tradi- tionally, functional areas are defined according to anatomical landmarks. Recently, new techniques were ... -
Depth Driven Photometric and Geometric Image Registration for Real-Time Stereo Systems
(The Eurographics Association, 2011)This paper presents a novel depth driven approach for a highly accurate joint photometric and geometric image alignment. Thereby, the registration problem is expressed in terms of a consistent, elegant and efficient energy ... -
Direct Visualization of Particle-Partition of Unity Data
(The Eurographics Association, 2011)Direct visualization of higher-order data provides manifold advantages over the traditional approach, which is based on resampling and subsequent visualization by interpolation-based techniques. Most important, it avoids ... -
Effective Back-Patch Culling for Hardware Tessellation
(The Eurographics Association, 2011)When rendering objects with hardware tessellation, back-facing patches should be culled as early as possible to avoid unnecessary surface evaluations, and setup costs for the tessellator and rasterizer. For dynamic objects ... -
Extracting Flow Structures Using Sparse Particles
(The Eurographics Association, 2011)In recent years, Lagrangian Coherent Structures (LCS) have been characterized using the Finite-Time Lyapunov Exponent, following the advection of a dense set of particles into a corresponding flow field. The large amount ... -
Extrinsic Self-Calibration of Time-of-Flight Cameras using a Combination of 3D and Intensity Descriptors
(The Eurographics Association, 2011)Time-of-Flight (ToF) cameras are able to simultaneously record intensity and depth images at a high frequency. Many applications require images that are recorded from different viewpoints. In order to consolidate the ... -
Fast and Efficient 3D Chamfer Distance Transform for Polygonal Meshes
(The Eurographics Association, 2011)We present an efficient GPU-based method to perform 3D chamfer distance transform (CDT) in a wavefront scheme. In this context, we also introduce a binary voxelization algorithm which provides the initial boundary condition ... -
A Framework for Interactive Visualization and Classification of Dynamical Processes at the Water Surface
(The Eurographics Association, 2011)A framework for the visualization and classification of multi-channel spatio-temporal data from water wave imaging is presented. Our interactive visualization tool, WaveVis, allows a detailed study of the water surface ... -
FreeCam: A Hybrid Camera System for Interactive Free-Viewpoint Video
(The Eurographics Association, 2011)We describe FreeCam - a system capable of generating live free-viewpoint video by simulating the output of a virtual camera moving through a dynamic scene. The FreeCam sensing hardware consists of a small number of static ... -
A Global Optimization Approach to High-detail Reconstruction of the Head
(The Eurographics Association, 2011)The paper presents an approach for reconstructing head-and-shoulder portraits of people from calibrated stereo images with a high level of geometric detail. In contrast to many existing systems, our reconstructions cover ... -
Implicit Filtering for Image and Shape Processing
(The Eurographics Association, 2011)The main purpose of this paper consists of demonstrating advantages of using implicit filtering schemes (noncausal IIR filters, in the signal processing language) for some basic image processing and geometric modeling ... -
Improving Stability and Compactness in Street Layout Visualizations
(The Eurographics Association, 2011)We present and evaluate improvements for Street Layout, a technique that can be used for visualizing evolving hierarchical data such as file structures or software systems. Street Layouts represent data as street networks, ... -
Instant Level-of-Detail
(The Eurographics Association, 2011)Highly detailed models are commonly used in computer games and other interactive rendering applications. In this context, static levels-of-detail are frequently used to achieve real-time frame rates. While this is a simple ... -
Interactive Exploration of Polymer-Solvent Interactions
(The Eurographics Association, 2011)The interaction of three-dimensional linked hydrophilic polymers with surrounding solvents in time-dependent data sets is of great interest for domain experts and current research in molecular dynamics. These polymers are ... -
Is it Necessary to Model the Matrix Degrading Enzymes for Simulating Tumour Growth?
