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 ... -
Spinoff - Transferring Energy between Real and Virtual Worlds
(The Eurographics Association, 2007)There is a widening gap between interaction devices for Virtual Environments and other factors such as graphical realism, accessibility and complexity. To address this problem, we developed a Mixed Reality environment that ... -
Stabilized Noise
(The Eurographics Association, 2007)Perlin noise is generated by interpolation of a pre-defined random number table. However since the random number table is generated without considering the ideal properties of noise for computer graphics, the resulting ... -
State-of-the-Art Computer Graphics in Neurosurgical Planning and Risk Assessment
(The Eurographics Association, 2007)We present a novel software assistant that unlocks new potentials in neurosurgical planning and risk assessment. It allows surgeons to approach the task in an intuitive manner, by providing them with the possibility to ... -
Take a Stroll in Another World
(The Eurographics Association, 2007)Another World II is a print by the famous Dutch artist M. C. Escher, depicting a cube with arch-like openings on each side. What makes the print interesting is that the depicted views in the arches are inconsistent, leaving ... -
A Unified Interpolatory and Approximation sqrt-3 Subdivision Scheme
(The Eurographics Association, 2007)We have found that there is a relationship between the cubic B-spline and four-point curve subdivision method. In the paper it is used to deduce interpolatory subdivision schemes from cubic B-spline based approximation ... -
View-based Shape Similarity using Mutual Information Spheres
(The Eurographics Association, 2007)We present a new method for computing the shape similarity between 3D polygonal models using an informationtheoretic viewpoint selection framework. Given a 3D model, a sphere of viewpoints surrounding this model is used ... -
Virtual Agent Navigation in Open Spaces using Iterative Shrinking Polygons
(The Eurographics Association, 2007)Populating an urban environment with a virtual crowd provides a dynamic element to an otherwise static scene; bringing the virtual environment to life. One of the fundamental components governing the fidelity of the scene ... -
Volumetric Normal Mapping in Rendering of Multivariate Volume Data
(The Eurographics Association, 2007)The work presented in this paper introduces volumetric normal maps for producing visual structure in direct volume rendering (DVR) of 3D data for the purpose of visualizing multiple attributes in a 3D volume. We use ...
