Adaptive Remeshing of Non-Manifold Surfaces
(The Eurographics Association, 2008)We present a unified approach for consistent remeshing of arbitrary non-manifold triangle meshes with additional user-defined feature lines, which together form a feature skeleton. Our method is based on local operations ... -
Artificial Mosaics by Gradient Vector Flow
(The Eurographics Association, 2008)In this paper a novel approach for artificial mosaic generation is proposed. Gradient Vector Flow computation together with heuristics to maximise the covered mosaic area are used. The high frequency details are managed ... -
Boolean Operations for Free-form Models Represented in Geometry Images
(The Eurographics Association, 2008)We present a Boolean operation algorithm for free-form solid models represented in geometry images. By taking advantage of the regular data organization of geometry images, our algorithm can perform efficient surface ... -
Compensation of the Light Attenuation with Depth of Images Captured by a Confocal Microscope Using a MRF Deformation Model and Graph Cuts
(The Eurographics Association, 2008)We study series of fluorescent optical sections, i.e. three-dimensional (3D) biomedical images, captured by a confocal laser scanning microscope (CLSM). Fluorescent image intensities of optical sections from deep layers ... -
Contact Skinning
(The Eurographics Association, 2008)In this paper, we propose a new approach to model interactions through a skinning method. Skinning is a frequently used technique to animate a mesh based on skeleton motion. In the case of a hand motion sequence used to ... -
Crowds in Context: Evaluating the Perceptual Plausibility of Pedestrian Orientations
(The Eurographics Association, 2008)We describe a work-in-progress evaluating the plausibility of pedestrian orientations. While many studies have focused on creating accurate or fast crowd simulation models for populating virtual cities or other environments, ... -
Efficient Soft Tissue Modelling Using Charged Particle Control Points
(The Eurographics Association, 2008)As the performance levels of personal computers increases so does the desire for more realistic and immersive software and simulation. An area where this is particularly the case is that of medical training simulation, ... -
Efficient Spherical Harmonics Lighting with the Preetham Skylight Model
(The Eurographics Association, 2008)We present a fast and compact representation of a skylight model for spherical harmonics lighting, especially for outdoor scenes. This representation allows dynamically changing the sun position and weather conditions on ... -
Efficient Visualization of Architectural Models from a Structure and Motion Pipeline
(The Eurographics Association, 2008)State of the art three dimensional reconstruction pipelines can nowadays produce models up to several million polygons without any human intervention from a set of digital images or video. Such models are able to stretch ... -
Evaluation of a Mobile MR Geovisualisation Interface
(The Eurographics Association, 2008)This paper presents experimental results of a mobile mixed reality interface designed for geovisualization of 3D realistic urban environments which allows dynamic switching between three visualization domains: a virtual ... -
FMDistance: A Fast and Effective Distance Function for Motion Capture Data
(The Eurographics Association, 2008)Given several motion capture sequences, of similar (but not identical) length, what is a good distance function? We want to find similar sequences, to spot outliers, to create clusters, and to visualize the (large) set of ... -
A Fragile Watermarking Scheme for Authentication of Semi-regular Meshes
(The Eurographics Association, 2008)This paper presents a fragile watermarking scheme for authentication of 3D semi-regular meshes. After one wavelet decomposition, the watermark is inserted by slightly modifying the norms and orientations of the obtained ... -
Identification of Dynamic Mass Spring Parameters for Deformable Body Simulation
(The Eurographics Association, 2008)Mass spring systems (MSS) are frequently used to simulate deformable objects because of their conceptual sim- plicity and computational speed. Unfortunately, the model parameters (spring coefficients, masses) are not related ... -
Improving Interaction Performance for Ray Tracing
(The Eurographics Association, 2008)We have developed an approach for improving the performance of object manipulation in ray tracing systems. We assume that users alternate between navigating the scene and manipulating objects in the scene. We divide the ... -
Interactive Stroke-Based NPR using Hand Postures on Large Displays
(The Eurographics Association, 2008)We explore the use of hand postures to interact with stroke-based rendering (SBR) on touch-sensitive large displays. In contrast to traditional WIMP interfaces, we allow people to directly engage with and influence a ... -
Knitty: 3D Modeling of Knitted Animals with a Production Assistant Interface
(The Eurographics Association, 2008)Knitty is an interactive design system for creating knitted animals. The user designs a 3D surface model using a sketching interface. The system automatically generates a knitting pattern and then visualizes the shape of ... -
Laziness is a Virtue: Motion Stitching Using Effort Minimization
(The Eurographics Association, 2008)Given two motion-capture sequences that are to be stitched together, how can we assess the goodness of the stitching? The straightforward solution, Euclidean distance, permits counter-intuitive results because it ignores ... -
Level of Detail Flow Simulation
(The Eurographics Association, 2008)In this paper we present a framework to simulate visually plausible large scale flow of fluids or smoke. To maintain real-time speed, we define the simulation over a coarse grid which is refined with a more detailed grid ... -
Measuring and Enhancing the Legibility of GPU-rendered Text
(The Eurographics Association, 2008)Whereas the rendering of tiny typefaces in 2D applications has been perfected over decades, the legibility of text in 3D visualizations has rarely been addressed. This affects road signs, meters, screens, and books in ... -
Microquad Soft Shadow Mapping Revisited
(The Eurographics Association, 2008)Recently, real-time soft shadow research saw many important contributions from the class of soft shadow mapping algorithms, where approximate occluder geometry is reconstructed from a shadow map and backprojected onto the ...
