Construction of Non-Blobby Surface from Particles
(The Eurographics Association, 2007)This paper presents a method that can construct a surface with a thin region or sharp edges from particles. The surface is constructed in two stages. An implicit surface is generated by assigning a density distribution to ... -
Enforcing Scene Constraints in Single View Reconstruction
(The Eurographics Association, 2007)Three-dimensional reconstruction from a single view is an under-constrained process that relies critically upon the availability of prior knowledge about the imaged scene. This knowledge is assumed to be supplied by a user ... -
Exact Computation of the Hausdorff Distance between Triangular Meshes
(The Eurographics Association, 2007)We present an algorithm that computes the exact Hausdorff distance between two arbitrary triangular meshes. Our method computes squared distances for each point on each triangle of one mesh to all relevant triangles of the ... -
Exemplar-based Worn Edges
(The Eurographics Association, 2007)To counteract the sterile look of computer-generated worlds, we introduce a procedural model for worn edges that can be seen in buildings and stones: edges that have suffered minor damage at multiple points, resulting in ... -
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 ... -
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 ... -
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 ... -
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. ... -
Real-Time 3D Lettering with a 2D Font Engine
(The Eurographics Association, 2007)Standard texturing shows a number of problems with 3D objects such as road signs, labels, or books. If letters are displayed at too large a scale, textures show blurred instead of hard edges; if letters are displayed at ... -
Reeb Chart Unfolding Based 3D Shape Signatures
(The Eurographics Association, 2007)This paper presents a novel surface parameterization based technique that addresses the pose insensitive shape signature problem for surface models of arbitrary genus. It is based on the key idea that two surface models ... -
Shape Analysis for Augmented Topological Shape Descriptor
(The Eurographics Association, 2007)In this work we propose a scheme for analysis of the shape of a 3D model.We use Extended Reeb Graph to describe the topological structure of the model which we further enrich with extracted geometrical features. The nodes ... -
Simultaneous Visualization of Preoperative Planning Models and Intraoperative 2D Ultrasound for Liver Surgery
(The Eurographics Association, 2007)This paper introduces new techniques for simultaneous visualization of preoperative planning models and intraoperative 2D ultrasound for open liver surgery. The driving motivation for our work is to improve the visual ...
