Chamber Recognition in Cave Data Sets
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Quantitative analysis of cave systems represented as 3D models is becoming more and more important in the field of cave sciences. One open question is the rigorous identification of chambers in a data set, which has a deep ... -
Character-Object Interaction Retrieval Using the Interaction Bisector Surface
(The Eurographics Association and John Wiley & Sons Ltd., 2017)In this paper, we propose a novel approach for the classification and retrieval of interactions between human characters and objects. We propose to use the interaction bisector surface (IBS) between the body and the object ... -
Computational Light Painting Using a Virtual Exposure
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Light painting is an artform where a light source is moved during a long-exposure shot, creating trails resembling a stroke on a canvas. It is very difficult to perform because the light source needs to be moved at the ... -
Consistent Video Filtering for Camera Arrays
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Visual formats have advanced beyond single-view images and videos: 3D movies are commonplace, researchers have developed multi-view navigation systems, and VR is helping to push light field cameras to mass market. However, ... -
Decoupled Opacity Optimization for Points, Lines and Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Displaying geometry in flow visualization is often accompanied by occlusion problems, making it difficult to perceive information that is relevant in the respective application. In a recent technique, named opacity ... -
DeepGarment: 3D Garment Shape Estimation from a Single Image
(The Eurographics Association and John Wiley & Sons Ltd., 2017)3D garment capture is an important component for various applications such as free-view point video, virtual avatars, online shopping, and virtual cloth fitting. Due to the complexity of the deformations, capturing 3D ... -
Design Transformations for Rule-based Procedural Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We introduce design transformations for rule-based procedural models, e.g., for buildings and plants. Given two or more procedural designs, each specified by a grammar, a design transformation combines elements of the ... -
Diffusion Diagrams: Voronoi Cells and Centroids from Diffusion
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We define Voronoi cells and centroids based on heat diffusion. These heat cells and heat centroids coincide with the common definitions in Euclidean spaces. On curved surfaces they compare favorably with definitions based ... -
EcoBrush: Interactive Control of Visually Consistent Large-Scale Ecosystems
(The Eurographics Association and John Wiley & Sons Ltd., 2017)One challenge in portraying large-scale natural scenes in virtual environments is specifying the attributes of plants, such as species, size and placement, in a way that respects the features of natural ecosystems, while ... -
Enriching Facial Blendshape Rigs with Physical Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Oftentimes facial animation is created separately from overall body motion. Since convincing facial animation is challenging enough in itself, artists tend to create and edit the face motion in isolation. Or if the face ... -
EUROGRAPHICS 2017: CGF 36-2 Frontmatter

Flicker Observer Effect: Guiding Attention Through High Frequency Flicker in Images
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Drawing the user's gaze to an important item in an image or a graphical user interface is a common challenge. Usually, some form of highlighting is used, such as a clearly distinct color or a border around the item. Flicker ... -
Flow-Induced Inertial Steady Vector Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Traditionally, vector field visualization is concerned with 2D and 3D flows. Yet, many concepts can be extended to general dynamical systems, including the higher-dimensional problem of modeling the motion of finite-sized ... -
Fully Spectral Partial Shape Matching
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We propose an efficient procedure for calculating partial dense intrinsic correspondence between deformable shapes performed entirely in the spectral domain. Our technique relies on the recently introduced partial functional ... -
General Point Sampling with Adaptive Density and Correlations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Analyzing and generating sampling patterns are fundamental problems for many applications in computer graphics. Ideally, point patterns should conform to the problem at hand with spatially adaptive density and correlations. ... -
Geometric Stiffness for Real-time Constrained Multibody Dynamics
(The Eurographics Association and John Wiley & Sons Ltd., 2017)This paper focuses on the stable and efficient simulation of articulated rigid body systems for real-time applications. Specifically, we focus on the use of geometric stiffness, which can dramatically increase simulation ... -
GPU Ray Tracing using Irregular Grids
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present a spatial index structure to accelerate ray tracing on GPUs. It is a flat, non-hierarchical spatial subdivision of the scene into axis aligned cells of varying size. In order to construct it, we first nest an ... -
A GPU-Adapted Structure for Unstructured Grids
(The Eurographics Association and John Wiley & Sons Ltd., 2017)A key advantage of working with structured grids (e.g., images) is the ability to directly tap into the powerful machinery of linear algebra. This is not much so for unstructured grids where intermediate bookkeeping data ... -
Gradient-based Steering for Vision-based Crowd Simulation Algorithms
(The Eurographics Association and John Wiley & Sons Ltd., 2017)Most recent crowd simulation algorithms equip agents with a synthetic vision component for steering. They offer promising perspectives through a more realistic simulation of the way humans navigate according to their ... -
Gradient-Domain Photon Density Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2017)The most common solutions to the light transport problem rely on either Monte Carlo (MC) integration or density estimation methods, such as uni- & bi-directional path tracing or photon mapping. Recent gradient-domain ...
