Generalized Discrete Ricci Flow
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Surface Ricci flow is a powerful tool to design Riemannian metrics by user defined curvatures. Discrete surface Ricci flow has been broadly applied for surface parameterization, shape analysis, and computational topology. ...
Mesh Segmentation Refinement
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
This paper proposes a method for refining existing mesh segmentations, employing a novel extension of the active contour approach to meshes. Given a segmentation, produced either by an automatic segmentation method or ...
Curvature Aware Fundamental Cycles
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We present a graph algorithm to find fundamental cycles aligned with the principal curvature directions of a surface. Specifically, we use the tree-cotree decomposition of graphs embedded in manifolds, guided with edge ...
SecondSkin: An interactive method for appearance transfer
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
SecondSkin estimates an appearance model for an object visible in a video sequence, without the need for complex interaction or any calibration apparatus. This model can then be transferred to other objects, allowing a ...
Frontmatter and Cover
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Expression Synthesis and Transfer in Parameter Spaces
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
In this paper, we introduce a novel framework that allows users to synthesize the expression of a 3D character by providing a intuitive set of parametric controls. Assuming that human face movements are formed by a set of ...
Simulation of Tearing Cloth with Frayed Edges
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Woven cloth can commonly be seen in daily life and also in animation. Unless prevented in some way, woven cloth usually frays at the edges. However, in computer graphics, woven cloth is typically modeled as a continuum ...
Simulating Gaseous Fluids with Low and High Speeds
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Gaseous fluids may move slowly, as smoke does, or at high speed, such as occurs with explosions. High-speed gas flow is always accompanied by low-speed gas flow, which produces rich visual details in the fluid motion. ...
Procedural Generation of Rock Piles using Aperiodic Tiling
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
In this paper, we present a tiling method for generating piles of rocks without any computationally demanding physically-based simulation. Previous techniques rely on a periodic tiling of rocks and generate unrealistic ...
Gradient-Preserving Color Transfer
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Color transfer is an image processing technique which can produce a new image combining one source image s contents with another image s color style. While being able to produce convincing results, however, Reinhard et al. ...
