    • Animation-Aware Quadrangulation 

      Marcias, Giorgio; Pietroni, Nico; Panozzo, Daniele; Puppo, Enrico; Sorkine-Hornung, Olga (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Geometric meshes that model animated characters must be designed while taking into account the deformations that the shape will undergo during animation. We analyze an input sequence of meshes with point-to-point correspondence, ...
    • CubeCover - Parameterization of 3D Volumes 

      Nieser, Matthias; Reitebuch, Ulrich; Polthier, Konrad (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Despite the success of quad-based 2D surface parameterization methods, effective parameterization algorithms for 3D volumes with cubes, i.e. hexahedral elements, are still missing. CUBECOVER is a first approach for generating ...
    • From A Medial Surface To A Mesh 

      Delamé, Thomas; Roudet, Céline; Faudot, Dominique (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Medial surfaces are well-known and interesting surface skeletons. As such, they can describe the topology and the geometry of a 3D closed object. The link between an object and its medial surface is also intuitively ...
    • Incorporating Sharp Features in the General Solid Sweep Framework 

      Adsul, Bharat; Machchhar, Jinesh; Sohoni, Milind (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. ...
    • 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 ...
    • Quaternion Julia Set Shape Optimization 

      Kim, Theodore (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present the first 3D algorithm capable of answering the question: what would a Mandelbrot-like set in the shape of a bunny look like? More concretely, can we find an iterated quaternion rational map whose potential field ...
    • Schrödinger Operator for Sparse Approximation of 3D Meshes 

      Choukroun, Yoni; Pai, Gautam; Kimmel, Ron (The Eurographics Association, 2017)
      We introduce a Schrödinger operator for spectral approximation of meshes representing surfaces in 3D. The operator is obtained by modifying the Laplacian with a potential function which defines the rate of oscillation of ...
    • Stream Surface Parametrization by Flow-Orthogonal Front Lines 

      Schulze, Maik; Germer, Tobias; Rössl, Christian; Theisel, Holger (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      The generation of discrete stream surfaces is an important and challenging task in scientific visualization, which can be considered a particular instance of geometric modeling. The quality of numerically integrated stream ...
    • Surface Patches from Unorganized Space Curves 

      Abbasinejad, Fatemeh; Joshi, Pushkar; Amenta, Nina (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Recent 3D sketch tools produce networks of three-space curves that suggest the contours of shapes. The shapes may be non-manifold, closed three-dimensional, open two-dimensional, or mixed. We describe a system that ...
