    • A Framework to Visualize and Interact with Multimodal Medical Images 

      Manssour, Isabel; Furuie, Sergio; Nedel, Luciana; Freitas, Carla (The Eurographics Association, 2001)
      The simultaneous use of images obtained from different sources is common in medical diagnosis. However, even though the quality of these images has been improving, the integration of multimodality data into a unique 3D ...

    • Framing the Challenges of Operational and Domain Usage of Volume Visualization Methods in Ocean Science 

      Bemis, Karen (The Eurographics Association, 2020)
      Several case studies are used to explore why the adoption of visualization software, especially for the visualization of 3D timevarying ocean data, has lagged behind the development of visualization techniques. The development ...

    • Frayed cell diagrams 

      Burch, Michael; Vehlow, Corinna; Weiskopf, Daniel (ACM, 2014)
      Tesselation-based or area-based visual representations are common to many artistic or visualization applications. For example, Voronoi art uses a space-filling tessellation of the image by Voronoi cells. We present frayed ...

    • FRED's Happy Factory 

      Baggett, Aaron; Jaeger, Alex; Lewis, Benjamin; Wardlaw, Isaac (The Eurographics Association, 2016)
      The primary driver of the recent resurgence in virtual reality has been video gaming, and while VR games are becoming an increasingly saturated market, they are likely to linger as the field's prime mover for several years ...

    • A Free Form Feature Taxonomy 

      Fontana, M.; Giannini, F.; Meirana, M. (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      In this paper the notion of free form feature for aesthetic design is presented. The design of industrial products constituted by free form surfaces is done by using CAD systems representing curves and surfaces by means ...

    • Free Form Incident Light Fields 

      Unger, J.; Gustavson, S.; Larsson, P.; Ynnerman, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents methods for photo-realistic rendering using strongly spatially variant illumination captured from real scenes. The illumination is captured along arbitrary paths in space using a high dynamic range, ...

    • Free Path Sampling in High Resolution Inhomogeneous Participating Media 

      Szirmay-Kalos, László; Tóth, Balázs; Magdics, Milán (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      This paper presents efficient algorithms for free path sampling in heterogeneous participating media defined either by high-resolution voxel arrays or generated procedurally. The method is based on the concept of mixing ...

    • Free-Form Deformation of Solid Models in CSR 

      Hui, K. C.; Lai, C.F. (Eurographics Association, 2001)
      Existing free-form deformation (FFD) techniques deform an object by deforming the space enclosing the object. Points on the object are thus deformed relative to the undeformed space (or world space). The deformed object ...

    • Free-form Implicit Haptic Rendering 

      Moustakas, Konstantinos (The Eurographics Association, 2013)
      This paper presents a framework for haptic rendering in virtual environments based on distance maps over implicit support plane mappings. Initially, a rigid 3D object is modelled using support plane mappings so as to ...

    • The Free-form Light Stage 

      Masselus, Vincent; Dutré, Philip; Anrys, Frederik (The Eurographics Association, 2002)
      We present the Free-form Light Stage, a system that captures the reflectance field of an object using a free-moving, hand-held light source. By photographing the object under different illumination conditions, we are able ...

    • Free-form Sketch 

      Wang, Haixiong; Markosian, Lee (The Eurographics Association, 2007)
      We describe a sketch-based system for modeling 3D shapes based on a new multiresolution shape representation we call a layered mesh. Like subdivision surfaces, layered meshes provide a multiresolution hierarchy of meshes. ...

    • Free-form sketching with variational implicit surfaces 

      Karpenko, Olga; Hughes, John F.; Raskar, Ramesh (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      With the advent of sketch-based methods for shape construction, there's a new degree of power available in the rapid creation of approximate shapes. Sketch [Zeleznik, 1996] showed how a gesture-based modeler could be used ...

    • Free-Form Solid Modellíng Based on Extended Simplícial Chains Using Triangular Bézier Patches 

      García, Ángel Luis; Miras, Juan Ruiz de; Feito, Francisco R. (The Eurographics Association, 2022)
      We present a mathematical model for geometric modelling based on the concept of extended simplicial chain (ESC) defined in previous works. With this model, a solid is defined by means of an algebraic sum of nondisjoint ...

    • Free-Form Surfaces Modeling by Evolution Simulation 

      Lienhardt, Pascal (Eurographics Association, 1988)
      We present in this paper a procedural method for modeling free-form, planar surfaces subdivisions, which allows simulating evolutions of such subdivisions. This method is founded on the common principles deduced from ...
