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 ...
Neighbor Embedding by Soft Kendall Correlation
(The Eurographics Association, 2013)
Correlation-based embedding of complex data relationships in a Euclidean space is studied. The proposed soft formulation of Kendall correlation allows for gradient-based optimization of scatter point neighborhood relationships ...
ViSMan-DHER: a Virtual Archaeology Application for Visualization and Management of Archaeological Data Related to ancient Herculaneum (NA), Italy
(The Eurographics Association, 2010)
This work aims at presenting a case-study application of ViSMan (Visual Scenarios Manager), an opensource framework developed at Cineca for visualization and interaction with virtual scientific models connected to digital ...
Volume Rendering Using Principal Component Analysis
(The Eurographics Association, 2016)
We investigate the use of Principal Component Analysis (PCA) for image-based volume rendering. We compute an eigenspace using training images, pre-rendered using a standard raycaster, from a spherically distributed range ...
State of the Art in Transfer Functions for Direct Volume Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
A central topic in scientific visualization is the transfer function (TF) for volume rendering. The TF serves a fundamental role in translating scalar and multivariate data into color and opacity to express and reveal the ...
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 ...
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 ...
