Modeling Terrains and Subsurface Geology
(The Eurographics Association, 2013)
The process of creating terrain and landscape models is important in a variety of computer graphics and visualization applications, from films and computer games, via flight simulators and landscape planning, to scientific ...
Transfinite Surface Patches Using Curved Ribbons
(The Eurographics Association, 2013)
An important problem in Computer Aided Design is to create digital representations for complex free-form objects that produce nice, predictable shapes and facilitate real-time editing in 3D. The clue to curve network-based ...
Direct Contouring of Implicit Closest Point Surfaces
(The Eurographics Association, 2013)
Constructing a (signed) distance field and contouring its zero level set are two important steps in many surface reconstruction methods. While most high-quality distance transforms compute the distance to the surface as ...
Coupled Quasi-harmonic Bases
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
The use of Laplacian eigenbases has been shown to be fruitful in many computer graphics applications. Today, state-of-the-art approaches to shape analysis, synthesis, and correspondence rely on these natural harmonic bases ...
Bilateral Hermite Radial Basis Functions for Contour-based Volume Segmentation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
In this paper, we propose a novel contour-based volume image segmentation technique. Our technique is based on an implicit surface reconstruction strategy, whereby a signed scalar field is generated from user-specified ...
Time-variant Volumetric Colors for Metamorphosis
(The Eurographics Association, 2013)
We propose to treat any changes in colors and textures in shape metamorphosis between two objects as time- dependent transformations of the volumetric distribution of materials. The main idea is to represent geometry of ...
