Geometric Modeling Based on Polygonal Meshesv
(Eurographics Association, 2000)While traditional computer aided design (CAD) is mainly based on piecewise polynomial surface representations, the recent advances in the efficient handling of polygonal meshes have made available a set of powerful techniques ... -
Volume Visualization and Volume Rendering Techniques
(Eurographics Association, 2000)There is a wide range of devices and scientific simulation generating volumetric data. Visualizing such data, ranging from regular data sets to scattered data, is a challenging task. This course will give an introduction ... -
Framework Technologies and Methods for Large Data Visualization
(Eurographics Association, 2000)- -
Shadow Computation: A Unified Perspective
(Eurographics Association, 2000)Methods for solving shadow problems by solving instances of visibility problems have long been known and exploited. There are, however, other potent uses of such a reduction of shadow problems, several of which we explore ... -
Geometric Signal Processing on Polygonal Meshes
(Eurographics Association, 2000)Very large polygonal models, which are used in more and more graphics applications today, are routinely generated by a variety of methods such as surface reconstruction algorithms from 3D scanned data, isosurface construction ... -
Interactive Display of Global Illumination Solutions for Non-Diffuse Environments
(Eurographics Association, 2000)In recent years there has been a lot of work on interactively displaying global illumination solutions for nondiffuse environments. This is an extremely active field of research, in which a lot of different approaches have ... -
Visual Perception in Realistic Image Synthesis
(Eurographics Association, 2000)Realism is often a primary goal in computer graphics imagery, we strive to create images that are perceptually indistinguishable from an actual scene. Rendering systems can now closely approximate the physical distribution ... -
Recent Advances in Visualization of Volumetric Data
(Eurographics Association, 2000)In the past few years, there have been key advances in the three main approaches to the visualization of volumetric data: isosurfacing, slicing and volume rendering, which together make up the field of volume visualization. ... -
The 3D Model Acquisition Pipeline
(Eurographics Association, 2000)Three-dimensional image acquisition systems are rapidly becoming more affordable, especially systems based on commodity electronic cameras. At the same time, personal computers with graphics hardware capable of displaying ... -
ALOHA : Adaptive Level Of Detail for Human Animation Towards a new framework
(Eurographics Association, 2000)The task of animating and rendering virtual humans in real-time is challenging. One must first establish a sense of realism through appearance, and then maintain this realism through correct and plausible motion, while ... -
An Accurate Illumination Model for Objects Coated with Multilayer Films
(Eurographics Association, 2000)This paper proposes an accurate illumination model for rendering objects coated with multilayer films. Optical phenomenaof multilayer films are caused by reflection, refraction, interference, and absorption of light inside ... -
MeshSweeper: From Closest Point to Hausdorff Distance Between Meshes
(Eurographics Association, 2000)We introduce a new algorithm for computing the distance from a point to an arbitrary polygonal mesh. Our algorithm uses a multi-resolution hierarchy of bounding volumes generated by geometric simplification. Our algorithm ... -
Visibility Complexity of a Region in Flatland
(Eurographics Association, 2000)The aim of this paper is to study the visibility complexity of different regions in a 2D scene. Based on mutual information, which we used in our previous work to define scene complexity, we propose two measures that ... -
A Facial Repertoire for Animation
(Eurographics Association, 2000)Character design and facial animation of characters is among the most tedious parts of creation of animations. In contrast to body animations, performer data have not been successfully used for faces. The CharToon system ... -
Volumetric Textures
(Eurographics Association, 2000)There are some types of nature elements that are adequately represented in Computer Graphics only through volumes. In order to visualize scenes with volumes, together with geometrical objects, it is necessary to make use ... -
Interactive Modelling of Convolution Surfaces with an Extendable User Interface
(Eurographics Association, 2000)Convolution surfaces enable the user to model complex free-form shapes. Due to analytical solutions for some kernel functions and skeletal elements, it is possible to model convolution surfaces interactively. An extendable ... -
Imaging Geometry for Concentric Mosaics
(Eurographics Association, 2000)Image-based models of environments can be captured with the use of a rotating video camera. In this paper we consider the nature of the display to develop a simple quantitative measure of the quality of ray sampling which ... -
A Procedural Approach to Solving Constraints of Articulated Bodies
(Eurographics Association, 2000)Realistic motions of articulated bodies are usually generated by using physically-based animation methods such as constrained dynamics. However, these methods involve heavy computations and complicated numerical methods. ... -
Visualizing Stars and Emission Nebulas
(Eurographics Association, 2000)We describe star and nebula visualization techniques used to create a 3D volumetric visualization of the Orion Nebula. The nebula’s ionization layer is modeled first as a surface model, derived from infrared and visible ... -
Towards Communicating Agents and Avatars in Virtual Worlds
(Eurographics Association, 2000)We report about ongoing research in a virtual reality environment where visitors can interact with agents that help them to obtain information, to perform certain transactions and to collaborate with them in order to get ...
