Cloth Animation and Rendering
(Eurographics Association, 2002)The area of physically-based modeling is situated in the intersection of computer science, mathematics, and physics. The animation of cloth is a particularly interesting application of physically-based modeling, because ... -
Concise Tour to the Virtual Old Prague
(Eurographics Association, 2002)This paper describes a structure and a user interface of the Internet based 3D presentation of existing historical part of city Prague. The application offers a smooth tour to selected regions of the real city, utilizing ... -
A Convolution-Based Algorithm for Animated Water Waves
(Eurographics Association, 2002)A non-linear partial differential equation solver is too sophisticated for computer graphics applications if they are only used to render effects like circular waves and ship wakes. We present an approach which simulates ... -
Dependent Tests Driven Filtering in Monte-Carlo Global Illumination
(Eurographics Association, 2002)This paper presents a multi-phase algorithm to solve the global illumination problem. In the first phase dependent tests are applied, i.e. the random walks of different pixels are built from the same random numbers. The ... -
Digital Watermarking for Volumetric Datasets
(Eurographics Association, 2002)An idea for digitaly watermarking volumetric datasets (VDS) and preliminary results from a test implementation are presented. It consists of a combination of filtering and rendering operations on volumetric data allowing ... -
Distance fields applied to character animation
(Eurographics Association, 2002)A general hybrid geometric-physical method that is useful for animating characters with skin, clothing and a MPEG-4 compatible face is presented. This method uses an approximation to the underlying musculo-skeletal structure ... -
Dynamic Motion Models
(Eurographics Association, 2002)Real-time animation of virtual characters is a demanding task. We propose dynamic motion models which can create the motion of a virtual character in different styles and have the ability to change the animation while it ... -
Dynamics-Based Motion Synthesis by Simple Learning Control
(Eurographics Association, 2002)Point-to-point motion of a humanoid agent (or any mobile creature) is considered as a composition of basic movements related to the degrees of freedom. With time/energy performance criteria, such movements can be synthesized ... -
Eurographics 2002 - Presentation of European Groups doing Computer Graphics Research
(Eurographics Association, 2002)This brochure contains a concentrated description of many European Computer Graphics research labs. It was produced to accompany a track of lab presentations at the annual conference Eurographics’2002 in Saarbrücken in ... -
Extraction of Critical Points and Nets Based on Discrete Gradient Vector Field
(Eurographics Association, 2002)In this paper we address the problem of representing the topology of discrete scalar fields defined on triangulated domains. To this aim, we use the notion of discrete gradient vector field that we have introduced in [4] ... -
Facial Modeling and Animation

Fast Volume Carving
(Eurographics Association, 2002)In recent years, the volumetric scene representation has been widely used in the fields of computer graphics and computer vision. In computer graphics, the representation is used to visualize and reconstruct 3D internal ... -
Feature Extraction and Visualisation of Flow Fields
(Eurographics Association, 2002)Flow visualisation has already been a very attractive part of visualisation research for a long time. Usually very large data sets need to be processed, which often consist of multivariate data with a large number of sample ... -
Feature interference in free form template matching
(Eurographics Association, 2002)Template matching is a useful method in the reconstruction of free form surfaces. In this paper, matching of free form surfaces with parameterized templates is studied with the emphasis on feature interference. By their ... -
Flexible bump map capture from video
(Eurographics Association, 2002)We extend recent techniques for the automated capture of surface normal maps or bump maps from real-world material samples. In contrast to recent systems, which have required cumbersome laboratory setups with careful ... -
Frame-Coherent Stippling
(Eurographics Association, 2002)Stippling is an artistic rendering technique where shading and texture is given by placing points or stipples on the canvas until the desired darkness is achieved. Computer-generated stippling has focused on producing high ... -
From Textual Chats to Interest Groups in 3D Virtual Space
(Eurographics Association, 2002)While the textual chat is a highly popular tool for various kinds of social interactions, its extension to the visual three-dimensional domain remains almost untouched and without practical utilization yet. This paper ... -
Function-defined shape node for VRML
(Eurographics Association, 2002)This paper describes how the web-based visualisation can be greatly improved using the function-based shape modelling technique. We propose the function-defined VRML shape node, which allows the content creators to describe ... -
Geometric Data Structures for Computer Graphics
(Eurographics Association, 2002)This tutorial aims at presenting a wide range of geometric data structures, algorithms and techniques from computational geometry to computer graphics practitioners. To achieve this goal we introduce several data structures, ... -
Geometric Simplification of Foliage
(Eurographics Association, 2002)One of the most important challenges in real-time rendering of outdoor scenes is the representation of vegetation. This is due to the vast amount of polygons that are used to model vegetable species. The present automatic ...
