Silhouette Extraction in Hough Space
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
Object-space silhouette extraction is an important problem in fields ranging from non-photorealistic computer graphics to medical robotics. We present an efficient silhouette extractor for triangle meshes under perspective ...
A Primer on Topological Persistence
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
The idea of topological persistence is to look at homological features that persist along a nested sequence of topo-logical spaces. As a typical example, we may take the sequence of sublevel sets of a function. The ...
Tuning Subdivision by Minimising Gaussian Curvature Variation Near Extraordinary Vertices
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
We present a method for tuning primal stationary subdivision schemes to give the best possible behaviour near extraordinary vertices with respect to curvature variation.Current schemes lead to a limit surface around ...
Towards a Unified Dynamical Solver for Computer Graphics
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
In this talk I will present some research I have done over the past few years in developing a unified dynamical solver for computer graphics. Currently many solvers are specialized for a given phenomenon such as fluid flow, ...
Data Preparation for Real-time High Quality Rendering of Complex Models
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
The capability of current 3D acquisition systems to digitize the geometry reflection behaviour of objects as well as the sophisticated application of CAD techniques lead to rapidly growing digital models which pose new ...

A Hierarchical Topology-Based Model for Handling Complex Indoor Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2006)
This paper presents a topology-based representation dedicated to complex indoor scenes. It accounts for memory management and performances during modelling, visualization and lighting simulation. We propose to enlarge a ...
Transformation and Normal Vector Calculation of Parametrically Defined Surfaces Based on Dual Vectors and Screw Theory: Application to Phong s Shading Model
(The Eurographics Association and Blackwell Publishing Ltd, 2006)
This paper presents a new approach for the transformation and normal vector calculation algorithms of parametrically defined surfaces via dual vectors and line transformations. The surface is defined via dual points, the ...
