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. ...
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. ...
Edit Propagation on Bidirectional Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We propose an efficient method for editing bidirectional texture functions (BTFs) based on edit propagation scheme. In our approach, users specify sparse edits on a certain slice of BTF. An edit propagation scheme is then ...
A Shape-Preserving Approach to Image Resizing
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We present a novel image resizing method which attempts to ensure that important local regions undergo a geometric similarity transformation, and at the same time, to preserve image edge structure. To accomplish this, we ...
