Shading Curves: Vector-Based Drawing With Explicit Gradient Control
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)A challenge in vector graphics is to define primitives that offer flexible manipulation of colour gradients. We propose a new primitive, called a shading curve, that supports explicit and local gradient control. This is ... -
Structure‐Aware Mesh Decimation
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel approach for the decimation of triangle surface meshes. Our algorithm takes as input a triangle surface mesh and a set of planar proxies detected in a pre‐processing analysis step, and structured via an ... -
Position‐Based Skinning for Soft Articulated Characters
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper, we introduce a two‐layered approach addressing the problem of creating believable mesh‐based skin deformation. For each frame, the skin is first deformed with a classic linear blend skinning approach, which ... -
A Survey of Physically Based Simulation of Cuts in Deformable Bodies
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Virtual cutting of deformable bodies has been an important and active research topic in physically based modelling and simulation for more than a decade. A particular challenge in virtual cutting is the robust and efficient ... -
Specular Lobe‐Aware Filtering and Upsampling for Interactive Indirect Illumination
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Although geometry‐aware filtering and upsampling have often been used for interactive or real‐time rendering, they are unsuitable for glossy surfaces because shading results strongly depend on the bidirectional reflectance ... -
Saliency‐Preserving Slicing Optimization for Effective 3D Printing
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an adaptive slicing scheme for reducing the manufacturing time for 3D printing systems. Based on a new saliency‐based metric, our method optimizes the thicknesses of slicing layers to save printing time and ... -
Optimization‐Based Gradient Mesh Colour Transfer
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)In vector graphics, gradient meshes represent an image object by one or more regularly connected grids. Every grid point has attributes as the position, colour and gradients of these quantities specified. Editing the ... -
Non‐Local Image Inpainting Using Low‐Rank Matrix Completion
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015).In this paper, we propose a highly accurate inpainting algorithm which reconstructs an image from a fraction of its pixels. Our algorithm is inspired by the recent progress of non‐local image processing techniques following ... -
Terrain Modelling from Feature Primitives
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce a compact hierarchical procedural model that combines feature‐based primitives to describe complex terrains with varying level of detail. Our model is inspired by skeletal implicit surfaces and defines the ... -
Separable Subsurface Scattering
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper, we propose two real‐time models for simulating subsurface scattering for a large variety of translucent materials, which need under 0.5 ms per frame to execute. This makes them a practical option for real‐time ... -
Interactive Procedural Modelling of Coherent Waterfall Scenes
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Combining procedural generation and user control is a fundamental challenge for the interactive design of natural scenery. This is particularly true for modelling complex waterfall scenes where, in addition to taking charge ... -
A Survey on Data‐Driven Video Completion
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Image completion techniques aim to complete selected regions of an image in a natural looking manner with little or no user interaction. Video Completion, the space–time equivalent of the image completion problem, inherits ... -
Forecast Verification and Visualization based on Gaussian Mixture Model Co‐estimation
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Precipitation forecast verification is essential to the quality of a forecast. The Gaussian mixture model (GMM) can be used to approximate the precipitation of several rain bands and provide a concise view of the data, ... -
Outdoor Human Motion Capture by Simultaneous Optimization of Pose and Camera Parameters
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a method for capturing the skeletal motions of humans using a sparse set of potentially moving cameras in an uncontrolled environment. Our approach is able to track multiple people even in front of cluttered and ... -
Trivariate Biharmonic B‐Splines
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015).In this paper, we formulate a novel trivariate biharmonic B‐spline defined over bounded volumetric domain. The properties of bi‐Laplacian have been well investigated, but the straightforward generalization from bivariate ... -
Accurate Computation of Single Scattering in Participating Media with Refractive Boundaries
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Volume caustics are high‐frequency effects appearing in participating media with low opacity, when refractive interfaces are focusing the light rays. Refractions make them hard to compute, since screen locality does not ... -
Computing Minimum Area Homologies
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Calculating and categorizing the similarity of curves is a fundamental problem which has generated much recent interest. However, to date there are no implementations of these algorithms for curves on surfaces with provable ... -

Supporting Focus and Context Awareness in 3D Modelling Tasks Using Multi‐Layered Displays
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Most 3D modelling software have been developed for conventional 2D displays, and as such, lack support for true depth perception. This contributes to making polygonal 3D modelling tasks challenging, particularly when models ... -
PIXEL2BRICK: Constructing Brick Sculptures from Pixel Art
(The Eurographics Association and John Wiley & Sons Ltd., 2015)LEGO, a popular brick-based toy construction system, provides an affordable and convenient way of fabricating geometric shapes. However, building arbitrary shapes using LEGO bricks with restrictive colors and sizes is not ...
