Scalar Tagged PN Triangles
(The Eurographics Association, 2005)This paper presents a new technique to convert a coarse polygonal geometric model into a smooth surface interpolating the mesh vertices, by improving the principle proposed by Vlachos et al. in their "Curved PN-Triangles". ... -
Constriction Computation using Surface Curvature
(The Eurographics Association, 2005)This paper provides a curvature-based algorithm to compute locally shortest geodesics on closed triangulated surfaces. These curves, which are called "constrictions", are useful for shape segmentation. The key idea of the ... -
Leaf Cluster Impostors for Tree Rendering with Parallax
(The Eurographics Association, 2005)This paper presents a simple method to render complex trees on high frame rates while maintaining parallax effects. Based on the recognition that a planar impostor is accurate if the represented polygon is in its plane, ... -
A 3D Perceptual Metric using Just-Noticeable-Difference
(The Eurographics Association, 2005)In multimedia applications, it is essential to distribute resources efficiently among different types of data in order to optimize overall quality. We propose a perceptual metric using Just-Noticeable-Difference (JND) to ... -
Perception-Based Rendering: Eyes Wide Bleached
(The Eurographics Association, 2005)Perception issues are a key factor in rendering Vision-Realistic images. This paper develops a novel spectral sensitive model of the Human Visual System (HVS) in order to simulate the bleaching effect in retinal photopigments. ... -
Using 3D Graphics for Learning and Collaborating Online
(The Eurographics Association, 2005)Today, the use of e-learning is common place. E-learning courses are now becoming prevalent on the Internet. They offer students great flexibility as well as a wide range of subjects. Traditionally the majority of these ... -
Fast Body-Cloth simulation with moving humanoids
(The Eurographics Association, 2005)In this paper we present a very fast method for body-cloth animation. The usual bottle-neck in cloth simulation performance is collision detection, which becomes more difficult to solve when a complex geometry, like a human ... -
Real-Time Rendering of Cloudy Natural Phenomena with Hierarchical Depth Impostors
(The Eurographics Association, 2005)This paper presents a real-time method to realistically render dynamic participating media under changing lighting conditions. In order to cope with performance requirements, the volume is built of instances of particle ... -
Multimodal Interfaces: an Introduction to ENACTIVE systems
(The Eurographics Association, 2005)Enactive Interfaces are related to a fundamental "interaction" concept which is not exploited by most of the existing human-computer interface technologies. The traditional interaction with the information mediated by a ... -
High Dynamic Range Techniques in Graphics: from Acquisition to Display
(The Eurographics Association, 2005)This course is motivated by tremendous progress in the development and accessibility of high dynamic range technology (HDR) that happened just recently, which creates many interesting opportunities and challenges in graphics. ... -
Real-Time Marching Cubes on the Vertex Shader
(The Eurographics Association, 2005)In this paper we propose a new approach for visualizing volumetric datasets by their isosurfaces. For an interactive isosurface reconstruction an optimized version of the well-known marching cubes algorithm is used. We ... -
Predicting Natural Hair Shapes by Solving the Statics of Flexible Rods
(The Eurographics Association, 2005)This paper presents a new physically-based method for predicting natural hairstyles in the presence of gravity and collisions. The method is based upon a mechanically accurate model for static elastic rods (Kirchhoff model), ... -
Function-based Shape Modeling Framework in Multilevel Education
(The Eurographics Association, 2005)We describe how an approach to the development of a shape modeling and visualization framework based on the rapidly progressing function representation can be used in education. The modeling language and software tools are ... -
Path Planning for Crowds: From Shared Goals to Individual Behaviors
(The Eurographics Association, 2005)This paper presents a novel approach for path planning in the context of crowds animation. The solution produces several paths joining each user-defined pair of locations in the environment. Pairs are possible initial/goal ... -
Computer Graphics Courseware
(The Eurographics Association, 2005)A lot of courseware tools suffer from the almost mutually exclusive goals of ease of usability on the one hand and extensibility and flexibility on the other hand. In most cases the tools are either ready-to-use applications ... -
Model-driven Virtual Mezzotint Techniques
(The Eurographics Association, 2005)Mezzotint is a traditional printing technique that is categorized into copperplate printing where an entire plate surface is roughened by some steel tools. In this paper the authors propose a method to realize two mezzotint ... -
Laplacian Mesh Processing
(The Eurographics Association, 2005)Surface representation and processing is one of the key topics in computer graphics and geometric modeling, since it greatly affects the range of possible applications. In this paper we will present recent advances in ...
