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 ... -
Ray Casting Algebraic Surfaces using the Frustum Form
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We propose an algorithm for interactive ray-casting of algebraic surfaces of high degree. A key point of our approach is a polynomial form adapted to the view frustum. This so called frustum form yields simple expressions ... -
Real-Time Rendering and Editing of Vector-based Terrains
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a method to populate very large terrains with very detailed features such as roads, rivers, lakes and fields. These features can be interactively edited, and the landscape can be explored in real time at any ... -
Real-Time Translucent Rendering Using GPU-based Texture Space Importance Sampling
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a novel approach for real-time rendering of translucent surfaces. The computation of subsurface scattering is performed by first converting the integration over the 3D model surface into an integration over a ... -
Real-Time Volumetric Tests Using Layered Depth Images
(The Eurographics Association, 2008)This paper presents a new approach for performing efficiently 3D point-in-volume tests for solid and arbitrary complex shapes. It classifies a 3D point as inside or outside of a solid specified by 3D polygonal geometry. ... -
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 ... -
Reduced Depth and Visual Hulls of Complex 3D Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Depth and visual hulls are useful for quick reconstruction and rendering of a 3D object based on a number of reference views. However, for many scenes, especially multi-object, these hulls may contain significant artifacts ... -
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 ... -
Render2MPEG: A Perception-based Framework Towards Integrating Rendering and Video Compression
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Currently 3D animation rendering and video compression are completely independent processes even if rendered frames are streamed on-the-fly within a client-server platform. In such scenario, which may involve time-varying ... -
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 ... -
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 ... -
The Role of Perception for Computer Graphics
(The Eurographics Association, 2008)Traditionally, computer graphics strived to achieve the technically best representation of the scenario or scene. For rendering, this lead to the preeminence of representations based on the physics of light interacting ...
