AdvectionBased Function Matching on Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2016)A tangent vector field on a surface is the generator of a smooth family of maps from the surface to itself, known as the flow. Given a scalar function on the surface, it can be transported, or advected, by composing it ... 
Complex Transfinite Barycentric Mappings with Similarity Kernels
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Transfinite barycentric kernels are the continuous version of traditional barycentric coordinates and are used to define interpolants of values given on a smooth planar contour. When the data is twodimensional, i.e. the ... 
Construction of Topologically Correct and Manifold Isosurfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a simple method to describe the geometry and topologically classify the intersection of level sets of trilinear interpolants with a reference unit cell. The solutions of three quadratic equations are used to ... 
Crawl through Neighbors: A Simple Curve Reconstruction Algorithm
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Given a planar point set sampled from an object boundary, the process of approximating the original shape is called curve reconstruction. In this paper, a novel nonparametric curve reconstruction algorithm based on Delaunay ... 
Curve Reconstruction with Many Fewer Samples
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We consider the problem of sampling points from a collection of smooth curves in the plane, such that the CRUST family of proximitybased reconstruction algorithms can rebuild the curves. Reconstruction requires a dense ... 
CustomCut: Ondemand Extraction of Customized 3D Parts with 2D Sketches
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Several applications in shape modeling and exploration require identification and extraction of a 3D shape part matching a 2D sketch. We present CustomCut, an ondemand part extraction algorithm. Given a sketched query, ... 
DataDriven Bending Elasticity Design by Shell Thickness
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a method to design the deformation behavior of 3D printed models by an interactive tool, where the variation of bending elasticity at different regions of a model is realized by a change in shell thickness. Given ... 
Deep Learning for Robust Normal Estimation in Unstructured Point Clouds
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Normal estimation in point clouds is a crucial first step for numerous algorithms, from surface reconstruction and scene understanding to rendering. A recurrent issue when estimating normals is to make appropriate decisions ... 
Disk Density Tuning of a Maximal Random Packing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We introduce an algorithmic framework for tuning the spatial density of disks in a maximal random packing, without changing the sizing function or radii of disks. Starting from any maximal random packing such as a Maximal ... 
Exploration of Empty Space among Spherical Obstacles via Additively Weighted Voronoi Diagram
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Properties of granular materials or molecular structures are often studied on a simple geometric model  a set of 3D balls. If the balls simultaneously change in size by a constant speed, topological properties of the empty ... 
Identifying Style of 3D Shapes using Deep Metric Learning
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a method that expands on previous work in learning human perceived style similarity across objects with different structures and functionalities. Unlike previous approaches that tackle this problem with the help ... 
Incorporating Sharp Features in the General Solid Sweep Framework
(The Eurographics Association and John Wiley & Sons Ltd., 2016)This paper extends a recently proposed robust computational framework for constructing the boundary representation (brep) of the volume swept by a given smooth solid moving along a one parameter family h of rigid motions. ... 
Interactive Modeling of Mechanical Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Objects with various types of mechanical joints are among the most commonly built. Joints implement a vocabulary of simple constrained motions (kinematic pairs) that can be used to build more complex behaviors. Defining ... 
Iterative Closest Conformal Maps between Planar Domains
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Conformal maps between planar domains are an important tool in geometry processing, used for shape deformation and image warping. The Riemann mapping theorem guarantees that there exists a conformal map between any two ... 
Learning 3D Scene Synthesis from Annotated RGBD Images
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present a datadriven method for synthesizing 3D indoor scenes by inserting objects progressively into an initial, possibly, empty scene. Instead of relying on few hundreds of handcrafted 3D scenes, we take advantage ... 
Mesh Statistics for Robust Curvature Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)While it is usually not difficult to compute principal curvatures of a smooth surface of sufficient differentiability, it is a rather difficult task when only a polygonal approximation of the surface is available, because ... 
Mobility Fitting using 4D RANSAC
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Capturing the dynamics of articulated models is becoming increasingly important. Dynamics, better than geometry, encode the functional information of articulated objects such as humans, robots and mechanics. Acquired dynamic ... 
NearIsometric Level Set Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Implicit representations of geometry have found applications in shape modeling, simulation, and other graphics pipelines. These representations, however, do not provide information about the paths of individual points as ... 
NonRigid Puzzles
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Shape correspondence is a fundamental problem in computer graphics and vision, with applications in various problems including animation, texture mapping, robotic vision, medical imaging, archaeology and many more. In ... 
Planar Minimization Diagrams via Subdivision with Applications to Anisotropic Voronoi Diagrams
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Let X = {f1, . . ., fn} be a set of scalar functions of the form fi : R2 →R which satisfy some natural properties. We describe a subdivision algorithm for computing a clustered eisotopic approximation of the minimization ...
