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 ... -
Group‐in‐a‐Box Meta‐Layouts for Topological Clusters and Attribute‐Based Groups: Space‐Efficient Visualizations of Network Communities and Their Ties
(The Eurographics Association and John Wiley and Sons Ltd., 2014)An important part of network analysis is understanding community structures like topological clusters and attribute‐based groups. Standard approaches for showing communities using colour, shape, rectangular bounding boxes, ... -
Exemplar‐Based Portrait Photograph Enhancement as Informed by Portrait Paintings
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper proposes an approach to enhance the regional contrasts in snap‐shot style portrait photographs by using pre‐modern portrait paintings as aesthetic exemplars. The example portrait painting is selected based on a ... -
Quad Layout Embedding via Aligned Parameterization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Quad layouting, i.e. the partitioning of a surface into a coarse network of quadrilateral patches, is a fundamental step in application scenarios ranging from animation and simulation to reverse engineering and meshing. ... -
Inexpensive Reconstruction and Rendering of Realistic Roadside Landscapes
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper, we present an inexpensive approach to create highly detailed reconstructions of the landscape surrounding a road. Our method is based on a space-efficient semi-procedural representation of the terrain and ... -
Mobility‐Trees for Indoor Scenes Manipulation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this work, we introduce the ‘mobility‐tree’ construct for high‐level functional representation of complex 3D indoor scenes. In recent years, digital indoor scenes are becoming increasingly popular, consisting of detailed ... -
Visibility Silhouettes for Semi‐Analytic Spherical Integration
(The Eurographics Association and John Wiley and Sons Ltd., 2014)At each shade point, the spherical visibility function encodes occlusion from surrounding geometry, in all directions. Computing this function is difficult and point‐sampling approaches, such as ray‐tracing or hardware ... -
Implicit Decals: Interactive Editing of Repetitive Patterns on Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Texture mapping is an essential component for creating 3D models and is widely used in both the game and the movie industries. Creating texture maps has always been a complex task and existing methods carefully balance ... -
Stackless Multi‐BVH Traversal for CPU, MIC and GPU Ray Tracing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Stackless traversal algorithms for ray tracing acceleration structures require significantly less storage per ray than ordinary stack‐based ones. This advantage is important for massively parallel rendering methods, where ... -
Subdivision Surfaces with Creases and Truncated Multiple Knot Lines
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We deal with subdivision schemes based on arbitrary degree B‐splines. We focus on extraordinary knots which exhibit various levels of complexity in terms of both valency and multiplicity of knot lines emanating from such ... -
Visualization of the Centre of Projection Geometrical Locus in a Single Image
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Single view reconstruction (SVR) is an important approach for 3D shape recovery since many non‐existing buildings and scenes are captured in a single image. Historical photographs are often the most precise source for ...
