    • An Efficient Solver for Two-way Coupling Rigid Bodies with Incompressible Flow 

      Aanjaneya, Mridul (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We present an efficient solver for monolithic two-way coupled simulation of rigid bodies with incompressible fluids that is robust to poor conditioning of the coupled system in the presence of large density ratios between ...
    • Coupled Fluid Density and Motion from Single Views 

      Eckert, Marie-Lena; Heidrich, Wolfgang; Thuerey, Nils (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We present a novel method to reconstruct a fluid's 3D density and motion based on just a single sequence of images. This is rendered possible by using powerful physical priors for this strongly under-determined problem. ...
    • Distributing and Load Balancing Sparse Fluid Simulations 

      Shah, Chinmayee; Hyde, David; Qu, Hang; Levis, Philip (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      This paper describes a general algorithm and a system for load balancing sparse fluid simulations. Automatically distributing sparse fluid simulations efficiently is challenging because the computational load varies across ...
    • Time-Domain Parallelization for Accelerating Cloth Simulation 

      Liang, Junbang; Lin, Ming C. (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Cloth simulations, widely used in computer animation and apparel design, can be computationally expensive for real-time applications. Some parallelization techniques have been proposed for visual simulation of cloth using ...

      Jeruzalski, Timothy; Kanji, John; Jacobson, Alec; Levin, David I. W. (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Methods to compress simulation data are invaluable as they facilitate efficient transmission along the visual effects pipeline, fast and efficient replay of simulations for visualization and enable storage of scientific ...
    • Cable Joints 

      Müller, Matthias; Chentanez, Nuttapong; Jeschke, Stefan; Macklin, Miles (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Robustly and efficiently simulating cables and ropes that are part of a larger system such as cable driven machines, cable cars or tendons in a human or robot is a challenging task. To be able to adapt to the environment, ...
    • Frontmatter: ACM SIGGRAPH / Eurographics Symposium of Computer Animation 2018 

      Thuerey, Nils; Beeler, Thabo (The Eurographics Association and John Wiley & Sons Ltd., 2018)
    • Functional Maps on Product Manifolds 

      Rodolà, Emanuele; Lähner, Zorah; Bronstein, Alex M.; Bronstein, Michael M.; Solomon, Justin (The Eurographics Association, 2018)
      We consider the tasks of representing, analyzing and manipulating maps between shapes. We model maps as densities over the product manifold of the input shapes; these densities can be treated as scalar functions and therefore ...
    • Solving PDEs on Deconstructed Domains 

      Sellán, Silvia; Cheng, Herng Yi; Ma, Yuming; Dembowski, Mitchell; Jacobson, Alec (The Eurographics Association, 2018)
      When finding analytical solutions to Partial Differential Equations (PDEs) becomes impossible, it is useful to approximate them via a discrete mesh of the domain. Sometimes a robust triangular (2D) or tetrahedral (3D) mesh ...
    • Denoising of Point-clouds Based on Structured Dictionary Learning 

      Sarkar, Kripasindhu; Bernard, Florian; Varanasi, Kiran; Theobalt, Christian; Stricker, Didier (The Eurographics Association, 2018)
      We formulate the problem of point-cloud denoising in terms of a dictionary learning framework over square surface patches. Assuming that many of the local patches (in the unknown noise-free point-cloud) contain redundancies ...
    • Using Mathematical Morphology to Simplify Archaeological Fracture Surfaces 

      ElNaghy, Hanan; Dorst, Leo (The Eurographics Association, 2018)
      It is computationally expensive to fit the high-resolution 3D meshes of abraded fragments of archaeological artefacts in a collection. Therefore, simplification of fracture surfaces while preserving the fitting essentials ...
    • Out-of-core Resampling of Gigantic Point Clouds 

      Bletterer, Arnaud; Payan, Frédéric; Antonini, Marc; Meftah, Anis (The Eurographics Association, 2018)
      Nowadays, LiDAR scanners are able to capture complex scenes of real life, leading to extremely detailed point clouds. However, the amount of points acquired (several billions) and their distribution raise the problem of ...
    • Frontmatter: Symposium on Geometry Processing 2018 - Posters 

      Ju, Tao; Vaxman, Amir (The Eurographics Association, 2018)
    • Sensor-aware Normal Estimation for Point Clouds from 3D Range Scans 

      Comino Trinidad, Marc; Andujar, Carlos; Chica, Antonio; Brunet, Pere (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Normal vectors are essential for many point cloud operations, including segmentation, reconstruction and rendering. The robust estimation of normal vectors from 3D range scans is a challenging task due to undersampling and ...
    • Constructing 3D CSG Models from 3D Raw Point Clouds 

      Wu, Qiaoyun; Xu, Kai; Wang, Jun (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      The Constructive Solid Geometry (CSG) tree, encoding the generative process of an object by a recursive compositional structure of bounded primitives, constitutes an important structural representation of 3D objects. ...
    • Möbius Registration 

      Baden, Alex; Crane, Keenan; Kazhdan, Misha (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Conformal parameterizations over the sphere provide high-quality maps between genus zero surfaces, and are essential for applications such as data transfer and comparative shape analysis. However, such maps are not unique: ...
    • Modular Latent Spaces for Shape Correspondences 

      Ganapathi-Subramanian, Vignesh; Diamanti, Olga; Guibas, Leonidas J. (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We consider the problem of transporting shape descriptors across shapes in a collection in a modular fashion, in order to establish correspondences between them. A common goal when mapping between multiple shapes is ...
