MoireTrees: Visualization and Interaction for Multi-Hierarchical Data
(The Eurographics Association, 2005)
Visualizing hierarchical data is one of the core areas of information visualization. Most of these techniques focus on single hierarchies hierarchies with a single root element and a single path to each element. In contrast, ...
High-Quality Volume Rendering with Resampling in the Frequency Domain
(The Eurographics Association, 2005)
This work introduces a volume rendering technique that is conceptually based on the shear-warp factorization. We propose to perform the shear transformation in the frequency domain. Unlike the standard shear-warp algorithm, ...
A Novel Approach To Vortex Core Region Detection
(The Eurographics Association, 2002)
In this paper we present a simple and efficient vortex core region detection algorithm based on ideas derived from combinatorial topology. These ideas originated from Sperner s lemma, which by itself is of little value to ...
ICT Investment Considerations and their Influence on the Socio-Economic Impact of Heritage Sites
(The Eurographics Association, 2006)
The following methodological model can be used as a platform for the study of the impact of information and communications technologies (ICT) at cultural heritage sites. The model has been developed through extensive, ...
Comparison of Morphological Pyramids for Multiresolution MIP Volume Rendering
(The Eurographics Association, 2002)
We recently proposed a multiresolution representation for maximum intensity projection (MIP) volume rendering based on morphological adjunction pyramids which allow progressive refinement and have the property of perfect ...
An Augmented Fast Marching Method for Computing Skeletons and Centerlines
(The Eurographics Association, 2002)
We present a simple and robust method for computing skeletons for arbitrary planar objects and centerlines for 3D objects. We augment the Fast Marching Method (FMM) widely used in level set applications 11 by computing the ...
Visualization of Bibliographic Networks with a Reshaped Landscape Metaphor
(The Eurographics Association, 2002)
We describe a novel approach to visualize bibliographic networks that facilitates the simultaneous identification of clusters (e.g., topic areas) and prominent entities (e.g., surveys or landmark papers). While employing ...
Watermarking and Digital Rights Management - A Pilot DRM System Implementation and Technical Guidelines to Cultural Digitization Projects
(The Eurographics Association, 2006)
The issue addressed in this paper is at first a brief presentation of the Technical Guidelines for IPR protection and management applied to Greek cultural digitization projects. Secondly, the work focuses on the analysis ...
A GPU-Supported Lossless Compression Scheme for Rendering Time-Varying Volume Data
(The Eurographics Association, 2010)
Since the size of time-varying volumetric data sets typically exceeds the amount of available GPU and main memory, out-of-core streaming techniques are required to support interactive rendering. To deal with the performance ...
Volumetric Evaluation of Meshless Data From Smoothed Particle Hydrodynamics Simulations
(The Eurographics Association, 2010)
As an alternative to conventional Eulerian methods in the field of computational fluid dynamics (CFD), smoothed particle hydrodynamics (SPH) has been developed. Its mesh-free method is useful in problems, especially, where ...
