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 ... -
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 ... -
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 ... -

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 ... -
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 ... -
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 ... -
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 ... -
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 ... -

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 ...
