3D Data Acquisition
(Eurographics Association, 2002)3D scanners and image acquisition systems are rapidly becoming more affordable and allow to build highly accurate models of real 3D objects in a cost- and time-effective manner. This tutorial will present the potential of ... -
3D Scanning Technology: Capabilities and Issues
(Eurographics Association, 2002)The recent evolution of graphics technology makes it possible to manage very complex models on inexpensive platforms. These impressive rendering capabilities should be paired with detailed and accurate digital models. The ... -
Adaptive Compression of Human Animation Data
(Eurographics Association, 2002)In this paper we introduce an adaptive motion compression technique using the discrete wavelet transform. Based on the analysis of human animation data, and its frequency contents, the wavelet analysis is utilised to achieve ... -
Adaptive Tessellation for Trimmed NURBS Surface
(Eurographics Association, 2002)We present an adaptive method for tessellating the trimmed NURBS surface in the parametric domain. Given a model space tolerance ε, the algorithm first splits the NURBS surface in both the U and V directions to fit within ... -
Artificial Animals and Humans: From Physics to Intelligence
(Eurographics Association, 2002)The confluence of virtual reality and artificial life, an emerging discipline that spans the computational and biological sciences, has yielded synthetic worlds inhabited by realistic, artificial flora and fauna. Artificial ... -
Automated Enhancement of 3D Models
(Eurographics Association, 2002)The acquisition of a 3D model of a real environment can be accomplished using range sensors. In practice, suitable sensors to densely cover a large environment are often impractical. This paper presents ongoing work on the ... -
Automatic Data Acquisition and Visualization for Usability Evaluation of Virtual Reality Systems
(Eurographics Association, 2002)Evaluating the usability of a Virtual Reality system is a common practice nowadays. However, gathering and analyzing the necessary data are time-consuming tasks and sometimes involve inconvenient changes to the system. The ... -
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] ... -
