Parallel Irradiance Caching for Interactive Monte-Carlo Direct Volume Rendering
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose a technique to build the irradiance cache for isotropic scattering simultaneously with Monte Carlo progressive direct volume rendering on a single GPU, which allows us to achieve up to four times increased ... -
Stability of Dissipation Elements: A Case Study in Combustion
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Recently, dissipation elements have been gaining popularity as a mechanism for measurement of fundamental properties of turbulent flow, such as turbulence length scales and zonal partitioning. Dissipation elements segment ... -
Extended Branch Decomposition Graphs: Structural Comparison of Scalar Data
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a method to find repeating topological structures in scalar data sets. More precisely, we compare all subtrees of two merge trees against each other - in an efficient manner exploiting redundancy. This provides ... -
Mandatory Critical Points of 2D Uncertain Scalar Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper introduces a novel, non-local characterization of critical points and their global relation in 2D uncertain scalar fields. The characterization is based on the analysis of the support of the probability density ... -
Extracting Features from Time-Dependent Vector Fields Using Internal Reference Frames
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Extracting features from complex, time-dependent flow fields remains a significant challenge despite substantial research efforts, especially because most flow features of interest are defined with respect to a given ... -
Opacity Optimization for Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In flow visualization, integral surfaces rapidly tend to expand, fold and produce vast amounts of occlusion. While silhouette enhancements and local transparency mappings proved useful for semi-transparent depictions, they ... -
Sets of Globally Optimal Stream Surfaces for Flow Visualization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Stream surfaces are a well-studied and widely used tool for the visualization of 3D flow fields. Usually, stream surface seeding is carried out manually in time-consuming trial and error procedures. Only recently automatic ... -

Hierarchical Opacity Optimization for Sets of 3D Line Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Abstract The selection of meaningful lines for 3D line data visualization has been intensively researched in recent years. Most approaches focus on single line fields where one line passes through each domain point. This ... -
Pathline Glyphs
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Visualization of pathlines is common and highly relevant for the analysis of unsteady flow. However, pathlines can intersect, leading to visual clutter and perceptual issues. This makes it intrinsically difficult to provide ... -
Multi-style Paper Pop-up Designs from 3D Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Paper pop-ups are interesting three-dimensional books that fascinate people of all ages. The design and construction of these pop-up books however are done manually and require a lot of time and effort. This has led to ... -
Dual-Color Mixing for Fused Deposition Modeling Printers
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this work we detail a method that leverages the two color heads of recent low-end fused deposition modeling (FDM) 3D printers to produce continuous tone imagery. The challenge behind producing such two-tone imagery is ... -
ExploreMaps: Efficient Construction and Ubiquitous Exploration of Panoramic View Graphs of Complex 3D Environments
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We introduce a novel efficient technique for automatically transforming a generic renderable 3D scene into a simple graph representation named ExploreMaps, where nodes are nicely placed point of views, called probes, and ... -
Clean Color: Improving Multi-filament 3D Prints
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Fused Filament Fabrication is an additive manufacturing process by which a 3D object is created from plastic filament. The filament is pushed through a hot nozzle where it melts. The nozzle deposits plastic layer after ... -
Flower Reconstruction from a Single Photo
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a semi-automatic method for reconstructing flower models from a single photograph. Such reconstruction is challenging since the 3D structure of a flower can appear ambiguous in projection. However, the flower ... -
Automatic Generation of Tourist Brochures
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel framework for the automatic generation of tourist brochures that include routing instructions and additional information presented in the form of so-called detail lenses. The first contribution of this ... -
Deformation with Enforced Metrics on Length, Area and Volume
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Techniques have been developed to deform a mesh with multiple types of constraints. One limitation of prior methods is that the accuracy of demanded metrics on the resultant model cannot be guaranteed. Adding metrics ... -
Accurate and Efficient Lighting for Skinned Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In the context of real-time, GPU-based rendering of animated skinned meshes, we propose a new algorithm to compute surface normals with minimal overhead both in terms of the memory footprint and the required per-vertex ... -
Designing Large-Scale Interactive Traffic Animations for Urban Modeling
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Designing and optimizing traffic behavior and animation is a challenging problem of interest to virtual environment content generation and to urban planning and design. While some traffic simulation methods have appeared ... -
Content-Aware Surface Parameterization for Interactive Restoration of Historical Documents
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present an interactive method to restore severely damaged historical parchments. When damaged by heat in a fire, such manuscripts undergo a complex deformation and contain various geometric distortions such as wrinkling, ...
