Applications of Information Theory to Computer Graphics
(The Eurographics Association, 2007)
We present different applications of information theory to computer graphics, based on the use of the measures of entropy, mutual information, f-divergences and generalized entropies. The application areas are hierarchical ...
Reeb Chart Unfolding Based 3D Shape Signatures
(The Eurographics Association, 2007)
This paper presents a novel surface parameterization based technique that addresses the pose insensitive shape signature problem for surface models of arbitrary genus. It is based on the key idea that two surface models ...
Painterly Effects Rendering with Focus Based Level of Detail
(The Eurographics Association, 2007)
We present a novel method for automatically creating scalable and portable 2D non-photorealistically rendered (NPR) images with painterly effects, with level of detail control. The novelty of the approach lies both in using ...
Tangible Heritage: Production of Astrolabes on a Laser Engraver
(The Eurographics Association, 2007)
The astrolabe, an analog computing device, used to be the iconic instrument of astronomers during the Middle Ages. It allowed a multitude of operations of practical astronomy which were otherwise cumbersome to perform in ...
The Visual Computing of Projector-Camera Systems
(The Eurographics Association, 2007)
This state-of-the-art report focuses on real-time image correction techniques that enable projector-camera systems to display images onto screens that are not optimized for projections, such as geometrically complex, colored ...
Spectral Methods for Mesh Processing and Analysis
(The Eurographics Association, 2007)
Spectral methods for mesh processing and analysis rely on the eigenvalues, eigenvectors, or eigenspace projections derived from appropriately defined mesh operators to carry out desired tasks. Early works in this area can ...
Photorealistic Real-Time Visualization of Cultural Heritage: A Case Study of Friedrichsburg Castle in Germany
(The Eurographics Association, 2007)
This paper presents a novel highly immersive and interactive VR (virtual reality) installation targeted on photorealistic real-time visualization. Although applicable to many other scenarios, this work is focused primarily ...
Bridging Semantic Web and Digital Shapes
(The Eurographics Association, 2007)
Since the volume of multimedia content available on the Web is continuously increasing, a clear need for advanced techniques capable of performing an effective retrieval and management of such data. In this context, in ...
Fast GPU-based Visibility Computation for Natural Illumination of Volume Data Sets
(The Eurographics Association, 2007)
Pre-computed radiance transfer (PRT) has been used to render volumetric data under distant low-frequency illumination at real-time rates, including natural illumination, soft shadows, attenuation from semi-transparent ...
Construction of Non-Blobby Surface from Particles
(The Eurographics Association, 2007)
This paper presents a method that can construct a surface with a thin region or sharp edges from particles. The surface is constructed in two stages. An implicit surface is generated by assigning a density distribution to ...
