      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 ...
    • Complex Transfinite Barycentric Mappings with Similarity Kernels 

      Chen, Renjie; Gotsman, Craig (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 inter-polants of values given on a smooth planar contour. When the data is two-dimensional, i.e. the ...

      Bennett, Huck; Papadopoulou, Evanthia; Yap, Chee (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 e-isotopic approximation of the minimization ...
    • Deep Learning for Robust Normal Estimation in Unstructured Point Clouds 

      Boulch, Alexandre; Marlet, Renaud (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 ...
    • Interactive Modeling of Mechanical Objects 

      Ureta, Francisca Gil; Tymms, Chelsea; Zorin, Denis (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 ...
    • Disk Density Tuning of a Maximal Random Packing 

      Ebeida, Mohamed S.; Rushdi, Ahmad A.; Awad, Muhammad A.; Mahmoud, Ahmed H.; Yan, Dong-Ming; English, Shawn A.; Owens, John D.; Bajaj, Chandrajit L.; Mitchell, Scott A. (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 ...
    • Stenciling: Designing Structurally-Sound Surfaces with Decorative Patterns 

      Schumacher, Christian; Thomaszewski, Bernhard; Gross, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a novel method to design shells with artistic cutouts in a manner that produces a stable final result. The process of stenciling, removing material with a fixed shape, is a particularly appealing way to introduce ...
    • Mesh Statistics for Robust Curvature Estimation 

      Váša, Libor; Vaněček, Petr; Prantl, Martin; Skorkovská, Věra; Martínek, Petr; Kolingerová, Ivana (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 ...
    • Data-Driven Bending Elasticity Design by Shell Thickness 

      Zhang, Xiaoting; Le, Xinyi; Wu, Zihao; Whiting, Emily; Wang, Charlie C. L. (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 ...
    • Non-Rigid Puzzles 

      Litany, Or; Rodolà, Emanuele; Bronstein, Alex M.; Bronstein, Michael M.; Cremers, Daniel (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 ...
    • Near-Isometric Level Set Tracking 

      Tao, Michael; Solomon, Justin; Butscher, Adrian (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 ...
    • Exploration of Empty Space among Spherical Obstacles via Additively Weighted Voronoi Diagram 

      Manak, Martin (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 ...
