Fast GPU-based Visibility Computation for Natural Illumination of Volume Data Sets
(The Eurographics Association, 2007)Pre-computed radiance transfer (PRT) has been used to render volumetric data under distant low-frequency illumination at real-time rates, including natural illumination, soft shadows, attenuation from semi-transparent ... -
Fast Hierarchical 3D Distance Transforms on the GPU
(The Eurographics Association, 2007)This paper describes a fast approximate approach for the GPU-based computation of 3D Euclidean distance transforms (DT), i.e. distance fields with associated vector information to the closest object point. Our hierarchical ... -
Fast Hierarchical Methods to Detect Collisions between Deformable Objects: A Comparison
(The Eurographics Association, 2007)The time complexity of a collision detection algorithm can be reduced to logarithmic in the number of tests performed when the objects are decomposed into a Bounding Volume (BV) tree hierarchy. It is well known that the ... -
Flatland: A Tool for Transforming Historical Sites into Archival Drawings
(The Eurographics Association, 2007)Detailed documentation of historical sites is important for archaeological discovery and cultural preservation. The traditional method of documentation is to hand sketch 2D drawings of the region. Laser range finders can ... -
Haptic Simulation, Perception and Manipulation of Deformable Objects
(The Eurographics Association, 2007)This tutorial addresses haptic simulation, perception and manipulation of complex deformable objects in virtual environments (VE). We first introduce HAPTEX, a research project dealing with haptic simulation and perception ... -
High Speed Skin Color Detection and Localization on a GPU
(The Eurographics Association, 2007)In this paper, we present a simple yet novel method for high speed skin color detection and localization on images and video using the Graphics Processing Unit (GPU) and common graphics programming techniques. Our approach ... -
Imperceptible Calibration for Radiometric Compensation
(The Eurographics Association, 2007)We present a novel multi-step technique for imperceptible geometry and radiometry calibration of projectorcamera systems. Our approach can be used to display geometry and color corrected images on non-optimized surfaces ... -
Improved Skeleton Computation of an Encoded Volume
(The Eurographics Association, 2007)In this communication, we present an improvement of an existing thinning algorithm that computes a surface skeleton from a binary volume. The method makes an intensive use of Boolean operations and works on a special ... -
An Interactive Exploration of the Virtual Stronghold Dillenburg
(The Eurographics Association, 2007)This paper presents the results of an interdisciplinary project aiming at the virtual three-dimensional reconstruction of the stronghold Dillenburg, which has been completely destroyed in 1768. For an interactive virtual ... -
Inverse Kinematics and Kinetics for Virtual Humanoids
(The Eurographics Association, 2007)The present tutorial deals with the use of inverse kinematics and kinetics for postural adaptations of virtual hu- manoids to different kind of constraints. It first proposes an overview of the problematic of this thematic ... -
Liquid Diffusion Model that Accounts for a Variety of Dyeing Parameters
(The Eurographics Association, 2007)This paper describes a method for simulating and visualizing dyeing based on weave patterns and the physical parameters of the threads and the dye. We apply Fick s second law with a variable diffusion coefficient, which ... -
Mapping highly detailed color information on extremely dense 3D models: the case of David s restoration
(The Eurographics Association, 2007)The support of advanced Information Technology (IT) to preservation, restoration and documentation of Cultural Heritage is becoming a very important goal for the research community. Michelangelo's David was one of the first ... -
New Trends in 3D Video
(The Eurographics Association, 2007)3D Video is an emerging and challenging research discipline that lives on the boundary between computer vision and computer graphics. The goal of researchers working in the field is to extract spatio-temporal models of ... -
Object-Oriented Shader Design
(The Eurographics Association, 2007)We present an extremely lightweight object-oriented framework for writing shaders. It provides a way to invoke methods of objects from the shading language and to use references of objects as normal variables. Classes are ... -
Painterly Effects Rendering with Focus Based Level of Detail
(The Eurographics Association, 2007)We present a novel method for automatically creating scalable and portable 2D non-photorealistically rendered (NPR) images with painterly effects, with level of detail control. The novelty of the approach lies both in using ... -
Pareto-Based Perceptual Metric for Imperceptible Simplification on Mobile Displays
(The Eurographics Association, 2007)Graphics on mobile devices has become popular because untethered computing is convenient and increases pro- ductivity. Mobile displays come in different resolutions that affect the scene Level-of-Detail (LoD) that users ... -
A Pen-based Interface for Generating Graphical Reports of Findings in Cardiac Catheterization
(The Eurographics Association, 2007)This paper introduces a pen-based interface for the graphical reporting of findings in cardiac catheterization. The user can interactively draw, erase, move, and deform coronary arteries as well as record stenoses on them. ... -
Photorealistic Real-Time Visualization of Cultural Heritage: A Case Study of Friedrichsburg Castle in Germany
(The Eurographics Association, 2007)This paper presents a novel highly immersive and interactive VR (virtual reality) installation targeted on photorealistic real-time visualization. Although applicable to many other scenarios, this work is focused primarily ...
