Controlled Metamorphosis Between Skeleton‐Driven Animated Polyhedral Meshes of Arbitrary Topologies
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Enabling animators to smoothly transform between animated meshes of differing topologies is a long‐standing problem in geometric modelling and computer animation. In this paper, we propose a new hybrid approach built upon ...
Structural Analysis of Multivariate Point Clouds Using Simplicial Chains
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Topological and geometrical methods constitute common tools for the analysis of high‐dimensional scientific data sets. Geometrical methods such as projection algorithms focus on preserving distances in the data set. ...
Spectral Analysis on Medial Axis of 2D Shapes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Shape analysis finds many important applications in shape understanding, matching and retrieval. Among the various shape analysis methods, spectral shape analysis aims to study the spectrum of the Laplace–Beltrami operator ...
Managing Spatial Selections With Contextual Snapshots
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Spatial selections are a ubiquitous concept in visualization. By localizing particular features, they can be analysed and compared in different views. However, the semantics of such selections often depend on specific ...
The PAG Crowd: A Graph Based Approach for Efficient Data‐Driven Crowd Simulation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We present a data‐driven method for the real‐time synthesis of believable steering behaviours for virtual crowds. The proposed method interlinks the input examples into a structure we call the perception‐action graph (PAG) ...
A Projective Framework for Polyhedral Mesh Modelling
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We present a novel framework for polyhedral mesh editing with face‐based projective maps that preserves planarity by definition. Such meshes are essential in the field of architectural design and rationalization. By using ...
Variational Tree Synthesis
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Modelling trees according to desired shapes is important for many applications. Despite numerous methods having been proposed in tree modelling, it is still a non‐trivial task and challenging. In this paper, we present a ...
Optimized Generation of Stereoscopic CGI Films by 3D Image Warping
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
The generation of a stereoscopic animation film requires doubling the rendering times and hence the cost. In this paper, we address this problem and propose an automatic system for generating a stereo pair from a given ...
Object Repositioning Based on the Perspective in a Single Image
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We propose an image editing system for repositioning objects in a single image based on the perspective of the scene. In our system, an input image is transformed into a layer structure that is composed of object layers ...
Appearance Stylization of Manhattan World Buildings
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We propose a method that generates stylized building models from examples (Figure ). Our method only requires minimal user input to capture the appearance of a Manhattan world (MW) building, and can automatically retarget ...
