  • Löffler, Falko; Schumann, Heidrun (The Eurographics Association, 2010)
    Terrain simplification generates multi-resolution models, from which - traditionally - irregular or semi-regular triangulations are extracted to render a terrain at a suitable level of detail. Recent terrain simplification ...
  • Campen, M.; Kobbelt, L. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Quad layouting, i.e. the partitioning of a surface into a coarse network of quadrilateral patches, is a fundamental step in application scenarios ranging from animation and simulation to reverse engineering and meshing. ...
  • Campen, Marcel (2014-12)
    The efficient, computer aided or automatic generation of quad layouts, i.e. the partitioning of an object’s surface into simple networks of conforming quadrilateral patches, is a task that – despite its importance and ...
  • Bommes, David; Lévy, Bruno; Pietroni, Nico; Puppo, Enrico; Silva, Claudio; Tarini, Marco; Zorin, Denis (The Eurographics Association, 2012)
    Triangle meshes have been nearly ubiquitous in computer graphics, and a large body of data structures and geometry processing algorithms based on them has been developed in the literature. At the same time, quadrilateral ...
  • Angell, Ian O.; Moore, Richard E.M. (The Eurographics Association, 1986)
  • Stam, Jos; Loop, Charles (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    In this paper we introduce a new subdivision operator that unifies triangular and quadrilateral subdivision schemes. Designers often want the added flexibility of having both quads and triangles in their models. It is also ...
  • Kaelberer, Felix; Nieser, Matthias; Polthier, Konrad (The Eurographics Association and Blackwell Publishing Ltd, 2007)
    We introduce an algorithm for the automatic computation of global parameterizations on arbitrary simplicial 2-manifolds, whose parameter lines are guided by a given frame field, for example, by principal curvature frames. ...
  • Bergou, Miklos; Wardetzky, Max; Harmon, David; Zorin, Denis; Grinspun, Eitan (The Eurographics Association, 2006)
    Relating the intrinsic Laplacian to the mean curvature normal, we arrive at a model for bending of inextensible surfaces. Due to its constant Hessian, our isometric bending model reduces cloth simulation times up to three-fold.
  • Bruijns, J. (The Eurographics Association, 1998)
    We propose to use quadratic Bezier triangles as additional drawing primitives: quadratic Bezier triangles require much less model data for faithful representation of curved surfaces than planar triangles. Therefore, they ...
  • Zhang, Tianxiang; Li, Sheng; Manocha, Dinesh; Wang, Guoping; Sun, Hanqiu (The Eurographics Association and John Wiley & Sons Ltd., 2015)
    Simultaneous multi-impact simulation is a challenging problem that frequently arises in physically-based modeling of rigid bodies. There are several physical criteria that should be satisfied for rigid body collision ...
  • Chung, Se-Joon; Kim, Junggon; Han, Shangchen; Pollard, Nancy S. (The Eurographics Association, 2015)
    One of the most compelling challenges in virtual reality today is to allow users to carry out virtual manipulation tasks using their hands. Multi-touch devices are an interesting interface for this task, as they are widely ...
  • Raskar, Ramesh; van Baar, Jeroen; Willwacher, Thomas; Rao, Srinivas (The Eurographics Association and Blackwell Publishing, Inc, 2004)
    Curved screens are increasingly being used for high-resolution immersive visualization environments. We describe a new technique to display seamless images using overlapping projectors on curved quadric surfaces such as ...
  • Hormann, Kai; Tarini, Marco (The Eurographics Association, 2004)
    The only surface primitives that are supported by common graphics hardware are triangles and more complex shapes have to be triangulated before being sent to the rasterizer. Even quadrilaterals, which are frequently used ...
  • Bommes, David (Bommes, 2012-10-11)
    Accurately describing the geometry of objects in a digital environment, i.e. computers, isan essential ingredient in many of nowadays applications. Often it is desired to forecastthe behavior of real phenomena which depend ...
  • Skrba, Ljiljana; Reveret, Lionel; Hetroy, Franck; Cani, Marie-Paule; O'Sullivan, Carol (The Eurographics Association, 2008)
    Films like Shrek, Madagascar, The Chronicles of Narnia and Charlotte s web all have something in common: realistic quadruped animations. While the animation of animals has been popular for a long time, the technical ...
  • Schroders, Marc F. A.; Gulik, Rob van (The Eurographics Association, 2006)
    Relief mapping is an image based technique for rendering surface details. It simulates depth on a polygonal model using a texture that encodes surface height. The presented method incorporates a quadtree structure to achieve ...
  • Oliver, M.A.; King, T.R.; Wiseman, N.E. (The Eurographics Association, 1984)
    An efficient method is described for turning a quadtree encoding of an image into scan lines. When implemented in hardware it becomes possible to generate video in real time for a raster display without the need for a ...
  • Martin, R.R.; Anguh, M.M. (Blackwell Science Ltd and the Eurographics Association, 1991)
    Transforms and quadtrees are both methods of representing information in an image in terms of the presence of information at differing length scales. This paper presents a mathematical relationship between these two ...
  • Bommes, David; Lévy, Bruno; Pietroni, Nico; Puppo, Enrico; Silva, Claudio; Tarini, Marco; Zorin, Denis (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    Triangle meshes have been nearly ubiquitous in computer graphics, and a large body of data structures and geometry processing algorithms based on them has been developed in the literature. At the same time, quadrilateral ...
  • Boyandin, Ilya; Bertini, Enrico; Lalanne, Denis (The Eurographics Association and Blackwell Publishing Ltd., 2012)
    We present a qualitative user study analyzing findings made while exploring changes over time in spatial interactions. We analyzed findings made by the study participants with flow maps, one of the most popular representations ...
