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 ... -
Visibility Preprocessing Using Spherical Sampling of Polygonal Patches
(Eurographics Association, 2002)A technique is presented that permits fast view-reconstruction of individual objects. This method improves a previous approach to solve the problem of approximated view reconstruction by combining clustering of polygons ... -
Real-Time Animated Grass
(Eurographics Association, 2002)We present a simple method to render fields of grass, animated in the wind, in real-time. The technique employs vertex shaders to render displacement maps with Russian-doll style transparent shells. Animation is achieved ... -
Global Illumination for Interactive Applications and High-Quality Animations
(Eurographics Association, 2002)One of the main obstacles to the use of global illumination in image synthesis industry is the considerable amount of time needed to compute the lighting for a single image. Until now, this computational cost has prevented ... -
Simulation of Cumuliform Clouds Based on Computational Fluid Dynamics
(Eurographics Association, 2002)Simulation of natural phenomena is one of the important research fields in computer graphics. In particular, clouds play an important role in creating images of outdoor scenes. Fluid simulation is effective in creating ... -
Improved Integration for Cloth Simulation
(Eurographics Association, 2002)Most methods of cloth simulation produce animations that do not move very freely; the result often looks like the material is “swimming”. The primary sources of this phenomenon are the non-physical dissipation terms often ... -
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 ... -
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] ... -
An Image-Based Radiosity Representation
(Eurographics Association, 2002)We present a geometry-independent radiosity representation which stems from image-based methodologies. Our image-based representation is inspired by the concept of layered depth images. To construct the radiosity function ... -
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 ... -
Rendering Artistic Line Drawings Using Off-the-Shelf 3-D Software
(Eurographics Association, 2002)Most commercial 3-D software packages used for animated films and still picture production offer merely rudimentary support for non-photorealistic rendering. However, nearly all of these packages possess interfaces which ... -
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 ... -
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 ... -
Measuring and Rendering Art Paintings Using an RGB Camera
(Eurographics Association, 2002)A method is proposed for measuring and rendering of art paints by using the simple system of an RGB camera only. The surface shape of an art painting is considered as a rough plane rather than a three-dimensional curved ... -
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 ... -
Interactive Visualization with Programmable Graphics Hardware
(Eurographics Association, 2002)One of the main scientific goals of visualization is the development of algorithms and appropriate data models which facilitate interactive visual analysis and direct manipulation of the increasingly large data sets which ... -
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 ... -
On the Integration of Synthetic Objects with Real-World Scenes
(Eurographics Association, 2002)This paper presents a method for integrating synthetic objects in real-world photographs. We take a set of photographs of a real scene and build a simple image-based model. We use high dynamic range images to build an ... -
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, ...
