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 ... -
Adaptable Anatomical Models for Realistic Bone Motion Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a system to reconstruct subject-specific anatomy models while relying only on exterior measurements represented by point clouds. Our model combines geometry, kinematics, and skin deformations (skinning). This ... -
Adaptive Recommendations for Enhanced Non-linear Exploration of Annotated 3D Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce a novel approach for letting casual viewers explore detailed 3D models integrated with structured spatially associated descriptive information organized in a graph. Each node associates a subset of the 3D ... -
Advances in Interaction with 3D Environments
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Various interaction techniques have been developed for interactive 3D environments. This paper presents an up‐to‐date and comprehensive review of the state of the art of non‐immersive interaction techniques for , , and , ... -
Analysis and Synthesis of 3D Shape Families via Deep-learned Generative Models of Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a method for joint analysis and synthesis of geometrically diverse 3D shape families. Our method first learns part-based templates such that an optimal set of fuzzy point and part correspondences is computed ... -
AppFusion: Interactive Appearance Acquisition Using a Kinect Sensor
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an interactive material acquisition system for average users to capture the spatially varying appearance of daily objects. While an object is being scanned, our system estimates its appearance on‐the‐fly and ... -
Approximating Free-form Geometry with Height Fields for Manufacturing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We consider the problem of manufacturing free-form geometry with classical manufacturing techniques, such as mold casting or 3-axis milling. We determine a set of constraints that are necessary for manufacturability and ... -
Approximating the Generalized Voronoi Diagram of Closely Spaced Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an algorithm to compute an approximation of the generalized Voronoi diagram (GVD) on arbitrary collections of 2D or 3D geometric objects. In particular, we focus on datasets with closely spaced objects; GVD ... -
Biologically-Inspired Visual Simulation of Insect Swarms
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Representing the majority of living animals, insects are the most ubiquitous biological organisms on Earth. Being able to simulate insect swarms could enhance visual realism of various graphical applications. However, the ... -
A Biophysically-Based Model of the Optical Properties of Skin Aging
(The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper presents a time-varying, multi-layered biophysically-based model of the optical properties of human skin, suitable for simulating appearance changes due to aging. We have identified the key aspects that cause ... -
Boundary Handling at Cloth–Fluid Contact
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a robust and efficient method for the two‐way coupling between particle‐based fluid simulations and infinitesimally thin solids represented by triangular meshes. Our approach is based on a hybrid method that ... -
Brushables: Example-based Edge-aware Directional Texture Painting
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper we present Brushables-a novel approach to example-based painting that respects user-specified shapes at the global level and preserves textural details of the source image at the local level. We formulate the ... -
Can Bi-cubic Surfaces be Class A?
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Class A surface' is a term in the automotive design industry, describing spline surfaces with aesthetic, non- oscillating highlight lines. Tensor-product B-splines of degree bi-3 (bicubic) are routinely used to generate ... -
Cell Lineage Visualisation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Cell lineages describe the developmental history of cell populations and are produced by combining time-lapse imaging and image processing. Biomedical researchers study cell lineages to understand fundamental processes ... -
CHC+RT: Coherent Hierarchical Culling for Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a new technique for in-core and out-of-core GPU ray tracing using a generalization of hierarchical occlusion culling in the style of the CHC++ method. Our method exploits the rasterization pipeline and hardware ... -
Collective Crowd Formation Transform with Mutual Information–Based Runtime Feedback
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)This paper introduces a new crowd formation transform approach to achieve visually pleasing group formation transition and control. Its core idea is to transform crowd formation shapes with a least effort pair assignment ... -
Color Sequence Preserving Decolorization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Many visualization techniques use images containing meaningful color sequences. If such images are converted to grayscale, the sequence is often distorted, compromising the information in the image.We preserve the significance ... -
