Real-Time Consensus-Based Scene Reconstruction Using Commodity Graphics Hardware?
(Blackwell Science Ltd and the Eurographics Association, 2003)We present a novel use of commodity graphics hardware that effectively combines a plane-sweeping algorithm with view synthesis for real-time, online 3D scene acquisition and view synthesis. Using real-time imagery from a ... -

Interpolating an Unlimited Number of Curves Meeting at Extraordinary Points on Subdivision Surfaces*
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Interpolating curves by subdivision surfaces is one of the major constraints that is partially addressed in the literature. So far, no more than two intersecting curves can be interpolated by a subdivision surface such as ... -
Quad/Triangle Subdivision
(Blackwell Publishers, Inc and the Eurographics Association, 2003)In this paper we introduce a new subdivision operator that unifies triangular and quadrilateral subdivision schemes. Designers often want the added flexibility of having both quads and triangles in their models. It is also ... -
Creation and Control of Real-time Continuous Level of Detail on Programmable Graphics Hardware
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Continuity in level of detail sequences is essential in hiding visual artefacts that occur when switching between discrete levels of detail. However, construction and implementation of these sequences is prohibitively ... -
Two-dimensional Potential Fields for Advanced Implicit Modeling Operators
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Current methods for building models using implicit volume techniques present problems defining accurate and controllable blend shapes between implicit primitives. We present new methods to extend the freedom and controllability ... -
Emotion Disc and Emotion Squares: Tools to Explore the Facial Expression Space
(Blackwell Publishers, Inc and the Eurographics Association, 2003)In the paper we present two novel interactive tools, Emotion Disc and Emotion Squares, to explore the facial expression space. They map navigation in a two-dimensional circle, by the first tool, or in two two-dimensional ... -
State of the Art in Global Illumination for Interactive Applications and High-quality Animations
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Global illumination algorithms are regarded as computationally intensive. This cost is a practical problem when producing animations or when interactions with complex models are required. Several algorithms have been ... -
Automatic Hybrid Hierarchy Creation: a Cost-model Based Approach
(Blackwell Publishers, Inc and the Eurographics Association, 2003)While using hierarchical search structures has been proved as one of the most efficient acceleration techniques when rendering complex scenes, automatic creation of appropriate hierarchies is not solved yet. Well-known ... -
The Perspective Silhouette of a Canal Surface
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We present an efficient and robust algorithm for parameterizing the perspective silhouette of a canal surface and detecting each connected component of the silhouette. A canal surface is the envelope of a moving sphere ... -
EG Network Service Computer Graphics forum
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Eurographics and Computer Graphics forum offer a variety of services on the international networks. You can find details of our latest events, how to prepare a paper for the conference or for the journal and much more ... -
On the Optimality of Valence-based Connectivity Coding
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We show that the average entropy of the distribution of valences in valence sequences for the class of manifold 3D triangle meshes and the class of manifold 3D polygon meshes is strictly less than the entropy of these ... -

A Survey of Real-time Soft Shadows Algorithms
(Blackwell Publishing, Inc and Eurographics Association, 2003)Recent advances in GPU technology have produced a shift in focus for real-time rendering applications, whereby improvements in image quality are sought in addition to raw polygon display performance. Rendering effects such ... -
Ray Tracing Surfaces with Contours
(Blackwell Publishing, Inc and Eurographics Association, 2003)We present two algorithms for ray tracing surfaces with contour lines that are level surfaces of scalar fields. One algorithm renders the contours as bands of constant finite width, while the other renders them as one ... -
BRDF Measurement Modelling using Wavelets for Efficient Path Tracing
(Blackwell Publishing, Inc and Eurographics Association, 2003)Physically based rendering needs numerical models from real measurements, or analytical models from material definitions, of the Bidirectional Reflectance Distribution Function (BRDF). However, measured BRDF data sets are ... -
Soft Object Modelling with Generalised ChainMail - Extending the Boundaries of Web-based Graphics
(Blackwell Publishing, Inc and Eurographics Association, 2003)Soft object modelling is crucial in providing realistic simulation of many surgical procedures. High accuracy is achievable using the Finite Element Method (FEM), but significant computational power is required. We are ... -
Automatic View Selection Using Viewpoint Entropy and its Application to Image-Based Modelling
(Blackwell Publishing, Inc and Eurographics Association, 2003)In the last decade a new family of methods, namely Image-Based Rendering, has appeared. These techniques rely on the use of precomputed images to totally or partially substitute the geometric representation of the scene. ...
