A Survey of Multi-faceted Graph Visualization
(The Eurographics Association, 2015)
Graph visualization is an important field in information visualization that is centered on the graphical display of graph-structured data. Yet real world data is rarely just graph-structured, but instead exhibits multiple ...
Selecting and Sharing Multidimensional Projection Algorithms: A Practical View
(The Eurographics Association, 2020)
Multidimensional Projection techniques are often used by data analysts for exploring multivariate datasets, but the task of selecting the best technique for the job is not trivial, as there are many candidates and the ...
An Improved Multiple Importance Sampling Heuristic for Density Estimates in Light Transport Simulations
(The Eurographics Association, 2018)
Vertex connection and merging (VCM) is one of the most robust light transport simulation algorithms developed so far. It combines bidirectional path tracing with photon mapping using multiple importance sampling (MIS). ...
Hierarchical Additive Poisson Disk Sampling
(The Eurographics Association, 2018)
Generating samples of point clouds and meshes with blue noise characteristics is desirable for many applications in rendering and geometry processing. Working with laser-scanned or lidar point clouds, we usually find region ...
Practical Shading of Height Fields and Meshes using Spherical Harmonic Exponentiation
(The Eurographics Association, 2015)
Interactively computing smooth shading effects from environmental lighting, such as soft shadows and glossy reflections, is a challenge in scenes with dynamic objects. We present a method to efficiently approximate these ...
MVN-Reduce: Dimensionality Reduction for the Visual Analysis of Multivariate Networks
(The Eurographics Association, 2017)
The analysis of Multivariate Networks (MVNs) can be approached from two different perspectives: a multidimensional one, consisting of the nodes and their multiple attributes, or a relational one, consisting of the network's ...
The Parallel Coordinates Matrix
(The Eurographics Association, 2012)
We introduce the parallel coordinates matrix (PCM) as the counterpart to the scatterplot matrix (SPLOM). Using a graph-theoretic approach, we determine a list of axis orderings such that all pairwise relations can be ...
Total Euler Characteristic as a Noise Measure to aid Transfer Function Design
(The Eurographics Association, 2013)
For image-based, semi- or fully automated design of transfer functions for direct volume rendering, it is beneficial to have an estimation of the noise level in the rendered image. A topology-motivated noise measure is ...
Interactive Hierarchical Quote Extraction for Content Insights
(The Eurographics Association, 2019)
This work presents a new approach to visually summarize large micro-document collections such as tweets. We extract frequent patterns of phrases as shortened quotes to present analysts an overview of popular snippets and ...
Grid-Free Surface Tracking on the GPU
(The Eurographics Association, 2015)
We present the first mesh-based surface tracker that runs entirely on the GPU. The surface tracker is both completely grid-free and fast which makes it suitable for the use in a large, unbounded domain. The key idea for ...
