Knitting a 3D Model
(The Eurographics Association and Blackwell Publishing Ltd, 2008)A knitted animal is made of a closed surface consisting of several knitted patches knitted out of yarn and stuffed with cotton (Fig. 1). We introduce a system to create a knitting pattern from a given 3D surface model ... -
Local Volume Preservation for Skinned Characters
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Generating plausible deformations of a character skin within the standard production pipeline is a challenge. This paper presents a volume preservation method dedicated to skinned characters. As usual, the character is ... -
Online Personalised Non-photorealistic Rendering Technique for 3D Geometry from Incremental Sketching
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper presents an online personalised non-photorealistic rendering (NPR) technique for 3D models generated from interactively sketched input. This technique has been integrated into a sketch-based modelling system. ... -
Part-type Segmentation of Articulated Voxel-Shapes using the Junction Rule
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a part-type segmentation method for articulated voxel-shapes based on curve skeletons. Shapes are considered to consist of several simpler, intersecting shapes. Our method is based on the junction rule: the ... -
Patch-type Segmentation of Voxel Shapes using Simplified Surface Skeletons
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a new method for decomposing a 3D voxel shape into disjoint segments using the shape s simplified surface-skeleton. The surface skeleton of a shape consists of 2D manifolds inside its volume. Each skeleton point ... -
Perceptual Evaluation of Color-to-Grayscale Image Conversions
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Color images often have to be converted to grayscale for reproduction, artistic purposes, or for subsequent processing. Methods performing the conversion of color images to grayscale aim to retain as much information about ... -
Photon-driven Irradiance Cache
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We describe a global illumination method combining two well known techniques: photon mapping and irradiance caching. The photon mapping method has the advantage of being view independent but requires a costly additional ... -

A Prism-Free Method for Silhouette Rendering in Inverse Displacement Mapping
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Silhouette is a key feature that distinguishes displacement mapping from normal mapping. However the silhouette rendering in the GPU implementation of displacement mapping (which is often called inversed displacement ... -
Progressive Interpolation based on Catmull-Clark Subdivision Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We introduce a scheme for constructing a Catmull-Clark subdivision surface that interpolates the vertices of a quadrilateral mesh with arbitrary topology. The basic idea here is to progressively modify the vertices of an ... -
Real-time Animation of Sand-Water Interaction
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Recent advances in physically-based simulations have made it possible to generate realistic animations. However, in the case of solid-fluid coupling, wetting effects have rarely been noticed despite their visual importance ... -
Real-Time Depth-of-Field Rendering Using Point Splatting on Per-Pixel Layers
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a real-time method for rendering a depth-of-field effect based on the per-pixel layered splatting where source pixels are scattered on one of the three layers of a destination pixel. In addition, the missing ... -
Reconstructing 3D Shape, Albedo and Illumination from a Single Face Image
(The Eurographics Association and Blackwell Publishing Ltd, 2008)The morphable model has been employed to efficiently describe 3D face shape and the associated albedo with a reduced set of basis vectors. The spherical harmonics (SH) model provides a compact basis to well approximate the ... -
Reconstructing head models from photographs for individualized 3D-audio processing
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Visual fidelity and interactivity are the main goals in Computer Graphics research, but recently also audio is assuming an important role. Binaural rendering can provide extremely pleasing and realistic three-dimensional ... -
A Resolution Independent Approach for the Accurate Rendering of Grooved Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper presents a method for the accurate rendering of path-based surface details such as grooves, scratches and similar features. The method is based on a continuous representation of the features in texture space, ... -
Robust and Efficient Wave Simulations on Deforming Meshes
(The Eurographics Association and Blackwell Publishing Ltd, 2008)The goal of this paper is to enable the interactive simulation of phenomena such as animated fluid characters. While full 3D fluid solvers achieve this with control algorithms, these 3D simulations are usually too costly ... -
Shape-simplifying Image Abstraction
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper presents a simple algorithm for producing stylistic abstraction of a photograph. Based on mean curvature flow in conjunction with shock filter, our method simplifies both shapes and colors simultaneously while ... -
Shrinkability Maps for Content-Aware Video Resizing
(The Eurographics Association and Blackwell Publishing Ltd, 2008)A novel method is given for content-aware video resizing, i.e. targeting video to a new resolution (which may involve aspect ratio change) from the original.We precompute a per-pixel cumulative shrinkability map which takes ... -
Simulating Inextensible Cloth Using Impulses
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Computer simulation of cloth is often plagued by springs being over-stretched. The evaluation of impulses to prevent over-stretching is explained step-by-step. Our impulse approach controls the length of springs by a ... -
Sketching MLS Image Deformations On the GPU
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper, we present an image editing tool that allows the user to deform images using a sketch-based interface. The user simply sketches a set of source curves in the input image, and also some target curves that the ...
