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 ... -
Lighting and Occlusion in a Wave-Based Framework
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present novel methods to enhance Computer Generated Holography (CGH) by introducing a complex-valued wave-based occlusion handling method. This offers a very intuitive and efficient interface to introduce optical elements ... -
Manifold-valued Thin-Plate Splines with Applications in Computer Graphics
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a generalization of thin-plate splines for interpolation and approximation of manifold-valued data, and demonstrate its usefulness in computer graphics with several applications from different fields. The ... -
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 ... -
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, ... -
Mobile 3D Graphics
(The Eurographics Association, 2008)Mobile phone handsets are fast becoming personal computing platforms and offer exciting new opportunities for graphics applications. They present the largest ever market opportunity for the graphics industry. Handset ... -
Modeling a Generic Tone-mapping Operator
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Although several new tone-mapping operators are proposed each year, there is no reliable method to validate their performance or to tell how different they are from one another. In order to analyze and understand the ... -
Multiperspective Modeling, Rendering, and Imaging
(The Eurographics Association, 2008)A perspective image represents the spatial relationships of objects in a scene as they appear from a single viewpoint. In contrast, a multiperspective image combines what is seen from several viewpoints into a single image. ... -
A Novel Approach to Support Quality of Experience in Remote Visualization on Mobile Devices
(The Eurographics Association, 2008)This paper proposes a novel approach to support Quality of Experience (QoE) in remote visualization on mobile devices. Image resolution, frame rate, compression ratio, color depth, and device throughput are simultaneously ... -
Perceptually-Motivated Graphics
(The Eurographics Association, 2008)In this half-day tutorial, we give an overview of the uses of knowledge about the human visual system, as applied to several aspects of computer graphics. In particular, we show how human visual perception applies to the ... -
Photo-realistic Rendering of Metallic Car Paint from Image-Based Measurements
(The Eurographics Association and Blackwell Publishing Ltd, 2008)State-of-the-art car paint shows not only interesting and subtle angular dependency but also significant spatial variation. Especially in sunlight these variations remain visible even for distances up to a few meters and ... -
Physically Based Modeling of Ice with Bubbles
(The Eurographics Association, 2008)Bubbles are an important characteristic that determine the appearance of ice. In this paper the authors propose a strategy in order to construct geometric representations of ice that integrates bubbles in an ice cube and ... -
Physically-Based Interactive Sand Simulation
(The Eurographics Association, 2008)The interactive simulation of 3D terrains has been approached from several perspectives. Due to the complexity of the system involved, most of the models proposed focus on a visually realistic animation of the scene, rather ... -
Post Facto Registration Tools for Urban Modelling
(The Eurographics Association, 2008)Urban modelling applications require high-precision geometric models both for graphical rendering and for engineering purposes. While geometric models, photographic images and laser-scanned point clouds are ideally ... -
Practical Product Importance Sampling for Direct Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a practical algorithm for sampling the product of environment map lighting and surface reflectance. Our method builds on wavelet-based importance sampling, but has a number of important advantages over previous ... -
Quadruped Animation
(The Eurographics Association, 2008)Films like Shrek, Madagascar, The Chronicles of Narnia and Charlotte s web all have something in common: realistic quadruped animations. While the animation of animals has been popular for a long time, the technical ...
