A Fast Simulation Method Using Overlapping Grids for Interactions between Smoke and Rigid Objects
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Recently, many techniques using computational fluid dynamics have been proposed for the simulation of natural phenomena such as smoke and fire. Traditionally, a single grid is used for computing the motion of fluids. When ...
Texture Synthesis From Photographs
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
The goal of texture synthesis is to generate an arbitrarily large high-quality texture from a small input sample. Generally, it is assumed that the input image is given as a flat, square piece of texture, thus it has to ...
CHC++: Coherent Hierarchical Culling Revisited
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a new algorithm for efficient occlusion culling using hardware occlusion queries. The algorithm significantly improves on previous techniques by making better use of temporal and spatial coherence of visibility. ...
The Shadow Meets the Mask: Pyramid-Based Shadow Removal
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
In this paper we propose a novel method for detecting and removing shadows from a single image thereby obtaining a high-quality shadow-free image. With minimal user assistance, we first identify shadowed and lit areas on ...
Distortion-Free Steganography for Polygonal Meshes
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a technique for steganography in polygonal meshes. Our method hides a message in the indexed rep-resentation of a mesh by permuting the order in which faces and vertices are stored. The permutation is relative ...
An Example-based Procedural System for Element Arrangement
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a method for synthesizing two dimensional (2D) element arrangements from an example. The main idea is to combine texture synthesis techniques based-on a local neighborhood comparison and procedural modeling ...
Image-based Shaving
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Many categories of objects, such as human faces, can be naturally viewed as a composition of several different layers. For example, a bearded face with glasses can be decomposed into three layers: a layer for glasses, a ...
Image-based Aging Using Evolutionary Computing
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Aging has considerable visual effects on the human face and is difficult to simulate using a universally-applicable global model. In this paper, we focus on the hypothesis that the patterns of age progression (and regression) ...
Visualizing Underwater Ocean Optics
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Simulating the in-water ocean light field is a daunting task. Ocean waters are one of the richest participating media, where light interacts not only with water molecules, but with suspended particles and organic matter ...
Effect of Character Animacy and Preparatory Motion on Perceptual Magnitude of Errors in Ballistic Motion
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
An increasing number of projects have examined the perceptual magnitude of visible artifacts in animated motion. These studies have been performed using a mix of character types, from detailed human models to abstract ...
