Shape Analysis for Augmented Topological Shape Descriptor
(The Eurographics Association, 2007)In this work we propose a scheme for analysis of the shape of a 3D model.We use Extended Reeb Graph to describe the topological structure of the model which we further enrich with extracted geometrical features. The nodes ... -
Shape Representations Based on Simplicial and Cell Complexes
(The Eurographics Association, 2007)Simplicial and cell complexes are the most common way to discretize 3D shapes and two-, three and higherdimensional scalar fields. In this state-of-the-art report, we review, analyze and compare data structures for simplicial ... -
Simultaneous Visualization of Preoperative Planning Models and Intraoperative 2D Ultrasound for Liver Surgery
(The Eurographics Association, 2007)This paper introduces new techniques for simultaneous visualization of preoperative planning models and intraoperative 2D ultrasound for open liver surgery. The driving motivation for our work is to improve the visual ... -
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 ... -
Spinoff - Transferring Energy between Real and Virtual Worlds
(The Eurographics Association, 2007)There is a widening gap between interaction devices for Virtual Environments and other factors such as graphical realism, accessibility and complexity. To address this problem, we developed a Mixed Reality environment that ... -
Stabilized Noise
(The Eurographics Association, 2007)Perlin noise is generated by interpolation of a pre-defined random number table. However since the random number table is generated without considering the ideal properties of noise for computer graphics, the resulting ... -
State of the Art in Ray Tracing Animated Scenes
(The Eurographics Association, 2007)Ray tracing has long been a method of choice for off-line rendering, but traditionally was too slow for interactive use. With faster hardware and algorithmic improvements this has recently changed, and real-time ray tracing ... -
State-of-the-Art Computer Graphics in Neurosurgical Planning and Risk Assessment
(The Eurographics Association, 2007)We present a novel software assistant that unlocks new potentials in neurosurgical planning and risk assessment. It allows surgeons to approach the task in an intuitive manner, by providing them with the possibility to ... -
Take a Stroll in Another World
(The Eurographics Association, 2007)Another World II is a print by the famous Dutch artist M. C. Escher, depicting a cube with arch-like openings on each side. What makes the print interesting is that the depicted views in the arches are inconsistent, leaving ... -
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 ... -
Teaching Data Structures and Algorithms through Graphics
(The Eurographics Association, 2007)This paper presents experiences from a first-time implementation of a data structures and algorithms course based on a specific computer graphics problem, namely surface reconstruction from unorganized points, as the ... -
Towards Automatic Character Skeletonization and Interactive Skin Deformation
(The Eurographics Association, 2007)Characters are of paramount importance in computer graphics since they enrich 3D worlds with immersion and life, and extend the range of possible applications. They are also very complex objects to manage due to their ... -
Towards the Virtual Physiological Human
(The Eurographics Association, 2007)The objective of this tutorial is to train students and researchers in the various domains involving the modelling and simulation of the human body for medical purposes. Human body representations have been used for centuries ... -

A Unified Interpolatory and Approximation sqrt-3 Subdivision Scheme
(The Eurographics Association, 2007)We have found that there is a relationship between the cubic B-spline and four-point curve subdivision method. In the paper it is used to deduce interpolatory subdivision schemes from cubic B-spline based approximation ... -
View-based Shape Similarity using Mutual Information Spheres
(The Eurographics Association, 2007)We present a new method for computing the shape similarity between 3D polygonal models using an informationtheoretic viewpoint selection framework. Given a 3D model, a sphere of viewpoints surrounding this model is used ... -
Virtual Agent Navigation in Open Spaces using Iterative Shrinking Polygons
(The Eurographics Association, 2007)Populating an urban environment with a virtual crowd provides a dynamic element to an otherwise static scene; bringing the virtual environment to life. One of the fundamental components governing the fidelity of the scene ... -
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 ... -
Visual Mining of Text Collections
(The Eurographics Association, 2007)What happens if you have to examine and reach conclusions from a considerable number of textual documents? If you are faced with this task or with developing tools for completing this task, this tutorial is for you. Examining ...
