Levels of Detail for Crowds and Groups
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Work on levels of detail for human simulation has occurred mainly on a geometrical level, either by reducing the numbers of polygons representing a virtual human, or replacing them with a two-dimensional imposter. Approaches ... -
Local Physical Models for Interactive Character Animation
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Our goal is to design and build a tool for the creation of expressive character animation. Virtual puppetry, also known as performance animation, is a technique in which the user interactively controls a character's motion. ... -
Metamorphosis of Polyhedral Surfaces using Decomposition
(Blackwell Publishers, Inc and the Eurographics Association, 2002)This paper describes an algorithm for morphing polyhedral surfaces based on their decompositions into patches. The given surfaces need neither be genus-zero nor two-manifolds. We present a new algorithm for decomposing ... -
Modeling Surperspective Projection of Landscapes for Geographical Guide-Map Generation
(Blackwell Science Ltd and the Eurographics Association, 2002)It is still challenging to generate hand-drawn pictures because they differ from ordinary photographs in that they are often drawn as seen from multiple viewpoints. This paper presents a new approach for modeling such ... -
Multi-Resolution Rendering of Complex Animated Scenes
(Blackwell Publishers, Inc and the Eurographics Association, 2002)We present a novel multi-resolution point sample rendering algorithm for keyframe animations. The algorithm accepts triangle meshes of arbitrary topology as input which are animated by specifying different sets of vertices ... -
Multiresolution Surfaces having Arbitrary Topologies by a Reverse Doo Subdivision Method
(Blackwell Publishers Ltd and the Eurographics Association, 2002)We have shown how to construct multiresolution structures for reversing subdivision rules using global least squares models (Samavati and Bartels, Computer Graphics Forum, 18(2):97-119, June 1999). As a result, semiorthogonal ... -

Object Space EWA Surface Splatting: A Hardware Accelerated Approach to High Quality Point Rendering
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Elliptical weighted average (EWA) surface splatting is a technique for high quality rendering of point-sampled 3D objects. EWA surface splatting renders water-tight surfaces of complex point models with high quality, ... -
Projective Texture Mapping with Full Panorama
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Projective texture mapping is used to project a texture map onto scene geometry. It has been used in many applications, since it eliminates the assignment of fixed texture coordinates and provides a good method of representing ... -
Psychovisual Evaluation of Lossy CMYK Image Compression for Printing Applications
(Blackwell Publishers Ltd and the Eurographics Association, 2002)In the digital prepress workflow, images are represented in the CMYK colour space. Lossy image compression alleviates the need for high storage and bandwidth capacities, resulting from the high spatial and tonal resolution. ... -
Real-time Animation of Dressed Virtual Humans
(Blackwell Publishers, Inc and the Eurographics Association, 2002)In this paper, we describe a method for cloth animation in real-time. The algorithm works in a hybrid manner exploiting the merits of both the physical-based and geometric deformations. It makes use of predetermined ... -
Recent Advances in Mesh Morphing
(Blackwell Publishers Ltd and the Eurographics Association, 2002)Meshes have become a widespread and popular representation of models in computer graphics. Morphing techniques aim at transforming a given source shape into a target shape. Morphing techniques have various applications ... -
Report of the Statutory Auditors to the General Meeting of the Members of Eurographics Association Geneva
(Blackwell Publishers, Inc and the Eurographics Association, 2002) -
Representation of Pseudo Inter-reflection and Transparency by Considering Characteristics of Human Vision
(Blackwell Publishers, Inc and the Eurographics Association, 2002)We have succeeded in developing a quick and fully automated system that can generate photo-realistic 3D CG data based on a real object. A major factor in this success comes from our findings through psychophysical experiments ... -
Sculpturing on Discrete Displacement Fields
(Blackwell Publishers, Inc and the Eurographics Association, 2002)A displacement field can be defined by a vector field and a height field on an orientable surfaceS, describing the direction and the amount of displacement to be applied toSin order to get a surface represented by the ... -

A Simple and Robust Mutation Strategy for the Metropolis Light Transport Algorithm
(Blackwell Publishers, Inc and the Eurographics Association, 2002)This paper presents a new mutation strategy for the Metropolis light transport algorithm, which works in the unit cube of pseudo-random numbers instead of mutating in the path space. This transformation makes the integrand ... -
A Skeleton-based Approach for Detection of Perceptually Salient Features on Polygonal Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2002)The paper presents a skeleton-based approach for robust detection of perceptually salient shape features. Given ashape approximated by a polygonal surface, its skeleton is extracted using a three-dimensional Voronoi ...
