Fast Force Field Approximation and its Application to Skeletonization of Discrete 3D Objects
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper we present a novel method to approximate the force field of a discrete 3d object with a time complexity that is linear in the number of voxels. We define a rule, similar to the distance transform, to propagate ... -
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 ... -
Floating Textures
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a novel multi-view, projective texture mapping technique. While previous multi-view texturing approaches lead to blurring and ghosting artefacts if 3D geometry and/or camera calibration are imprecise, we propose ... -
Fluid in Video: Augmenting Real Video with Simulated Fluids
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a technique for coupling simulated fluid phenomena that interact with real dynamic scenes captured as a binocular video sequence. We first process the binocular video sequence to obtain a complete 3D reconstruction ... -
FMDistance: A Fast and Effective Distance Function for Motion Capture Data
(The Eurographics Association, 2008)Given several motion capture sequences, of similar (but not identical) length, what is a good distance function? We want to find similar sequences, to spot outliers, to create clusters, and to visualize the (large) set of ... -
A Fragile Watermarking Scheme for Authentication of Semi-regular Meshes
(The Eurographics Association, 2008)This paper presents a fragile watermarking scheme for authentication of 3D semi-regular meshes. After one wavelet decomposition, the watermark is inserted by slightly modifying the norms and orientations of the obtained ... -
From a Light CG Framework to a strong Cannibal Experience
(The Eurographics Association, 2008)Game development courses are being more and more deployed within computer graphics (CG) curricula. A fundamental element in the pedagogical effectiveness of such courses is the quality of the development framework provided ... -

Geometric Modeling Based on Polygonal Meshes
(The Eurographics Association, 2008)Polygonal meshes are nowadays intensively used in many different areas of computer graphics and geometry processing. In classical CAGD polygonal meshes developed into a valuable alternative to traditional spline surfaces, ... -
GPU Accelerated Direct Volume Rendering on an Interactive Light Field Display
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a GPU accelerated volume ray casting system interactively driving a multi-user light field display. The display, driven by a single programmable GPU, is based on a specially arranged array of projectors and a ... -
GPU-based Fast Ray Casting for a Large Number of Metaballs
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Metaballs are implicit surfaces widely used to model curved objects, represented by the isosurface of a density field defined by a set of points. Recently, the results of particle-based simulations have been often visualized ... -
Graphics based Computer Adaptive Testing and Beyond
(The Eurographics Association, 2008)Instead of computer games, animations, cartoons, and videos being used only for entertainment by kids, there is now an interest in using graphics for 'innovative testing'. Rather than traditional pen-and-paper tests, audio, ... -
Hardware-Accelerated, High-Quality Rendering Based on Trivariate Splines Approximating Volume Data
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We develop an approach for hardware-accelerated, high-quality rendering of volume data using trivariate splines. The proposed quasi-interpolating schemes are realtime reconstructions. The low total degrees provide several ... -
High-Resolution Volumetric Computation of Offset Surfaces with Feature Preservation
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a new algorithm for the efficient and reliable generation of offset surfaces for polygonal meshes. The algorithm is robust with respect to degenerate configurations and computes (self-)intersection free offsets ... -
Higher Order Barycentric Coordinates
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In recent years, a wide range of generalized barycentric coordinates has been suggested. However, all of them lack control over derivatives. We show how the notion of barycentric coordinates can be extended to specify ... -
Identification of Dynamic Mass Spring Parameters for Deformable Body Simulation
(The Eurographics Association, 2008)Mass spring systems (MSS) are frequently used to simulate deformable objects because of their conceptual sim- plicity and computational speed. Unfortunately, the model parameters (spring coefficients, masses) are not related ... -
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) ... -
Image-Based Empirical Information Acquisition, Scientific Reliability, and Long-Term Digital Preservation for the Natural Sciences and Cultural Heritage
(The Eurographics Association, 2008)The tools and standards of best practice adopted by natural science and cultural heritage (CH) professionals will determine the digital future of natural science and CH digital imaging work. This tutorial discusses emerging ... -
Image-based Material Weathering
(The Eurographics Association and Blackwell Publishing Ltd, 2008)The appearance manifold [WTL*06] is an efficient approach for modeling and editing time-variant appearance of materials from the BRDF data captured at single time instance. However, this method is difficult to apply in ... -
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 ...
