3D Lip-Synch Generation with Data-Faithful Machine Learning
(The Eurographics Association and Blackwell Publishing Ltd, 2007)This paper proposes a new technique for generating three-dimensional speech animation. The proposed technique takes advantage of both data-driven and machine learning approaches. It seeks to utilize the most relevant part ... -
3D Video Billboard Clouds
(The Eurographics Association and Blackwell Publishing Ltd, 2007)3D video billboard clouds reconstruct and represent a dynamic three-dimensional scene using displacement-mapped billboards. They consist of geometric proxy planes augmented with detailed displacement maps and combine the ... -
Adaptive Space Deformations Based on Rigid Cells
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We propose a new adaptive space deformation method for interactive shape modeling. A novel energy formulation based on elastically coupled volumetric cells yields intuitive detail preservation even under large deformations. ... -
A Bidirectional Light Field - Hologram Transform
(The Eurographics Association and Blackwell Publishing Ltd, 2007)In this paper, we propose a novel framework to represent visual information. Extending the notion of conventional image-based rendering, our framework makes joint use of both light fields and holograms as complementary ... -
Bitmask Soft Shadows
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Recently, several real-time soft shadow algorithms have been introduced which all compute a single shadow map and use its texels to obtain a discrete scene representation. The resulting micropatches are backprojected onto ... -
Boundary Constrained Swept Surfaces for Modelling and Animation
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Due to their simplicity and intuitiveness, swept surfaces are widely used in many surface modelling applications. In this paper, we present a versatile swept surface technique called the boundary constrained swept surfaces. ... -
Consistent Viewing and Interaction for Multiple Users in Projection-Based VR Systems
(The Eurographics Association and Blackwell Publishing Ltd, 2007)In projection-based Virtual Reality (VR) systems, typically only one headtracked user views stereo images rendered from the correct view position. For other users, who are presented a distorted image, moving with the first ... -
Context-Aware Skeletal Shape Deformation
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We describe a system for the animation of a skeleton-controlled articulated object that preserves the fine geometric details of the object skin and conforms to the characteristic shapes of the object specified through a ... -
Contrast Restoration by Adaptive Countershading
(The Eurographics Association and Blackwell Publishing Ltd, 2007)The ABSTRACT is to be in fully-justified italicized text, between two horizontal lines, in one-column format, below the author and affiliation information. Use the word Abstract as the title, in 9-point Times, boldface ... -
Crowds by Example
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present an example-based crowd simulation technique. Most crowd simulation techniques assume that the behavior exhibited by each person in the crowd can be defined by a restricted set of rules. This assumption limits ... -
Defocus Magnification
(The Eurographics Association and Blackwell Publishing Ltd, 2007)A blurry background due to shallow depth of field is often desired for photographs such as portraits, but, unfortunately, small point-and-shoot cameras do not permit enough defocus because of the small diameter of their ... -
Depth-of-Field Rendering by Pyramidal Image Processing
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present an image-based algorithm for interactive rendering depth-of-field effects in images with depth maps. While previously published methods for interactive depth-of-field rendering suffer from various rendering ... -
Diorama Construction From a Single Image
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Diorama artists produce a spectacular 3D effect in a confined space by generating depth illusions that are faithful to the ordering of the objects in a large real or imaginary scene. Indeed, cognitive scientists have ... -
Efficient Reflectance and Visibility Approximations for Environment Map Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present a technique for approximating isotropic BRDFs and precomputed self-occlusion that enables accurate and efficient prefiltered environment map rendering. Our approach uses a nonlinear approximation of the BRDF as ... -
A Finite Element Method on Convex Polyhedra
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present a method for animating deformable objects using a novel finite element discretization on convex polyhedra. Our finite element approach draws upon recently introduced 3D mean value coordinates to define smooth ... -
A Generic Pigment Model for Digital Painting
(The Eurographics Association and Blackwell Publishing Ltd, 2007) -
Geodesic-Controlled Developable Surfaces for Modeling Paper Bending
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present a novel and effective method for modeling a developable surface to simulate paper bending in interactive and animation applications. The method exploits the representation of a developable surface as the envelope ... -
Global Illumination using Photon Ray Splatting
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present a novel framework for efficiently computing the indirect illumination in diffuse and moderately glossy scenes using density estimation techniques. Many existing global illumination approaches either quickly ... -
Head-eye Animation Corresponding to a Conversation for CG Characters
(The Eurographics Association and Blackwell Publishing Ltd, 2007)CG character animations, in which CG characters engage in conversations, are widely used in multimedia contents such as videos and games. In constructing such an animation, we should consider about many factors, such as ... -
High-Quality Adaptive Soft Shadow Mapping
(The Eurographics Association and Blackwell Publishing Ltd, 2007)The recent soft shadow mapping technique [GBP06] allows the rendering in real-time of convincing soft shadows on complex and dynamic scenes using a single shadow map. While attractive, this method suffers from shadow ...
