Implicit Incompressible SPH on the GPU
(The Eurographics Association, 2015)
This paper presents CUDA-based parallelization of implicit incompressible SPH (IISPH) on the GPU. Along with the detailed exposition of our implementation, we analyze various components involved for their costs. We show ...
Improved Sparse Seeding for 3D Electrostatic Field Lines
(The Eurographics Association, 2015)
We present an improved seeding strategy for sparse visualization of electrostatic fields. By analyzing the curvature of the field lines, we extract points of extremal field strength between charges of different sign and ...
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 ...
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 ...
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 ...
The Bounced Z-buffer for Indirect Visibility
(The Eurographics Association, 2015)
Synthesizing images of animated scenes with indirect illumination and glossy materials at interactive frame rates commonly ignores indirect shadows. In this work we extend a class of indirect lighting algorithms that splat ...
Visual Techniques to Support Exploratory Analysis of Temporal Graph Data
(The Eurographics Association, 2015)
Recently, much research has focused on developing techniques for the visual representation of temporal graph data. This paper takes a wider look at the visual techniques involved in exploratory analysis of such data, ...
ColorCAT: Guided Design of Colormaps for Combined Analysis Tasks
(The Eurographics Association, 2015)
Colormap design is challenging because the encoding must match the requirements of data and analysis tasks as well as the perception of the target user. A number of well-known tools exist to support the design of colormaps. ...
Ambient Grids: Maintain Context-Awareness via Aggregated Off-Screen Visualization
(The Eurographics Association, 2015)
When exploring large spatial datasets, zooming and panning interactions often lead to the loss of contextual overview. Existing overview-plus-detail approaches allow users to view context while inspecting details, but they ...
Trajectory-based Visual Analytics for Anomalous Human Movement Analysis using Social Media
(The Eurographics Association, 2015)
The rapid development and increasing availability of mobile communication and location acquisition technologies allow people to add location data to existing social networks so that people share location-embedded information. ...
