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 ...
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 ...
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 ...
