Automated Combination of Real-Time Shader Programs
(The Eurographics Association, 2007)This work proposes an approach for automatic and generic runtime-combination of high-level shader programs. Many of recently introduced real-time rendering techniques rely on such programs. The fact that only a single ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Bridging Semantic Web and Digital Shapes
(The Eurographics Association, 2007)Since the volume of multimedia content available on the Web is continuously increasing, a clear need for advanced techniques capable of performing an effective retrieval and management of such data. In this context, 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 ... -
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 ... -
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 ... -
An Accurate Implicit Field Representation for Meshes and Its Adapted Triangulation Algorithms
(The Eurographics Association, 2007)The classic implicit scalar field distance transform representation of a mesh is very useful to perform many mesh processing operations and to obtain better results than with other methods. In this paper we propose a new ... -
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 ... -
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 ...
