Sketch-Based Procedural Surface Modeling and Compositing Using Surface Trees
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a system for creating and manipulating layered procedural surface editing operations, which is motivated by the limited support for iterative design in free-form modeling. A combination of sketch-based and ...
Modeling a Generic Tone-mapping Operator
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Although several new tone-mapping operators are proposed each year, there is no reliable method to validate their performance or to tell how different they are from one another. In order to analyze and understand the ...
Mining Motifs from Human Motion
(The Eurographics Association, 2008)
Mining frequently occurring temporal motion patterns (motion motifs) is important for understanding, organizing and retrieving motion data. However, without any a priori knowledge of the motifs, such as their lengths, ...
Multiperspective Modeling, Rendering, and Imaging
(The Eurographics Association, 2008)
A perspective image represents the spatial relationships of objects in a scene as they appear from a single viewpoint. In contrast, a multiperspective image combines what is seen from several viewpoints into a single image. ...
Physically-Based Interactive Sand Simulation
(The Eurographics Association, 2008)
The interactive simulation of 3D terrains has been approached from several perspectives. Due to the complexity of the system involved, most of the models proposed focus on a visually realistic animation of the scene, rather ...
Microquad Soft Shadow Mapping Revisited
(The Eurographics Association, 2008)
Recently, real-time soft shadow research saw many important contributions from the class of soft shadow mapping algorithms, where approximate occluder geometry is reconstructed from a shadow map and backprojected onto the ...
Zippy: A Framework for Computation and Visualization on a GPU Cluster
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Due to its high performance/cost ratio, a GPU cluster is an attractive platform for large scale general-purpose computation and visualization applications. However, the programming model for high performance general-purpose ...
Manifold-valued Thin-Plate Splines with Applications in Computer Graphics
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a generalization of thin-plate splines for interpolation and approximation of manifold-valued data, and demonstrate its usefulness in computer graphics with several applications from different fields. The ...
Augmented Panoramic Video
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
Many video sequences consist of a locally dynamic background containing moving foreground subjects. In this paper we propose a novel way of re-displaying these sequences, by giving the user control over a virtual camera ...
Real-Time Rendering and Editing of Vector-based Terrains
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We present a method to populate very large terrains with very detailed features such as roads, rivers, lakes and fields. These features can be interactively edited, and the landscape can be explored in real time at any ...
