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 ...
Programmable Graphics Hardware for Interactive Visualization

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 ...
