Virtual Hair Handle: A Model for Haptic Hairstyling
(The Eurographics Association, 2008)The process of styling virtual hair is a tedious task for 3D artists, who would significantly profit from more natural and intuitive ways of creating virtual hairstyles - such as, for example, the possibility to simply ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Shadowed Relighting of Dynamic Geometry with 1D BRDFs
(The Eurographics Association, 2008)We present a method for synthesizing the dynamic self-occlusion of an articulating character in real-time (> 170Hz) while incorporating reflection effects from 1D BRDFs under dynamic lighting and view conditions. We ... -
Rendering Method for Flat Origami
(The Eurographics Association, 2008)In flat Origami (Origami which is folded flat), some cases exist that have a closed-loop in the overlap order of faces after they are folded. It is difficult to display this shape correctly on the screen when Origami is ... -
Volume Data Visualization Using Fractal Interpolation Surfaces
(The Eurographics Association, 2008)Visualization of medical or experimental data is often achieved by extracting an intermediate geometric representation of the data. One such popular method for extracting an isosurface from volume data is the Marching Cubes ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Recognition of Human Actions using Layered Hidden Markov Models
(The Eurographics Association, 2008)Human activity recognition has been a major goal of research in the field of human - computer interaction. This paper proposes a method which employs a hierarchical structure of Hidden Markov Models (Layered HMMs) in an ... -
Mining Motifs from Human Motion
(The Eurographics Association, 2008)Mining frequently occurring temporal motion patterns (motion motifs) is important for understanding, organizing and retrieving motion data. However, without any a priori knowledge of the motifs, such as their lengths, ... -
Revealing Pentimenti Through Raking Angle Photography
(The Eurographics Association, 2008)Discovering hidden details in historical paintings, such as pentimenti, can help reveal historical influences and changing intentions of an artist. Top-down photographs of visible light historical paintings do not capture ... -
Video Carving
(The Eurographics Association, 2008)We present a technique for summarizing a video into a short segment, while preserving the important events in the original. While many techniques remove whole frames from the video stream when condensing it, we observe ... -
Removing Artifacts Due To Frequency-Domain Processing of Light-Fields
(The Eurographics Association, 2008)In previous works, light-field capture has been analyzed in spatio-angular representation. A light-field camera samples the optical signal within a single photograph by multiplexing the 4D radiance onto the physical 2D ...
