Geometry Textures and Applications
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Geometry textures are a novel geometric representation for surfaces based on height maps. The visualization is done through a graphics processing unit (GPU) ray casting algorithm applied to the whole object. At rendering ... -
GPU-Based Spherical Light Field Rendering with Per-Fragment Depth Correction
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Image-based rendering techniques are a powerful alternative to traditional polygon-based computer graphics. This paper presents a novel light field rendering technique which performs per-pixel depth correction of rays for ... -
High Performance GPU-based Proximity Queries using Distance Fields
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Proximity queries such as closest point computation and collision detection have many applications in computer graphics, including computer animation, physics-based modelling, augmented and virtual reality. We present ... -
High-speed Marching Cubes using HistoPyramids
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present an implementation approach for Marching Cubes (MC) on graphics hardware for OpenGL 2.0 or comparable graphics APIs. It currently outperforms all other known graphics processing units (GPU)-based iso-surface ... -
Mapping Highly Detailed Colour Information on Extremely Dense 3D Models: The Case of David s Restoration
(The Eurographics Association and Blackwell Publishing Ltd, 2008)The support of advanced information technology (IT) to preservation, restoration and documentation of Cultural Heritage (CH) is becoming a very important goal for the research community. Michelangelo s David was one of the ... -
Peek-in-the-Pic: Flying Through Architectural Scenes From a Single Image*
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Many casually taken tourist photographs comprise of architectural objects like houses, buildings, etc. Reconstructing such 3D scenes captured in a single photograph is a very challenging problem. We propose a novel ... -
Real-Time Indirect Illumination and Soft Shadows in Dynamic Scenes Using Spherical Lights
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a method for rendering approximate soft shadows and diffuse indirect illumination in dynamic scenes. The proposed method approximates the original scene geometry with a set of tightly fitting spheres. In previous ... -

Tangible Heritage: Production of Astrolabes on a Laser Engraver
(The Eurographics Association and Blackwell Publishing Ltd, 2008)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 ... -
Transferring the Rig and Animations from a Character to Different Face Models
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We introduce a facial deformation system that allows artists to define and customize a facial rig and later apply the same rig to different face models. The method uses a set of landmarks that define specific facial features ... -
The Visual Computing of Projector-Camera Systems
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This article 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, coloured and textured ... -
Untitled
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a planarity constraint and a novel three-dimensional (3D) point reconstruction algorithm for a multiview laser range slit scanner. The constraint is based on the fact that all observed points on a projected laser ...
