      Igarashi, T.; Moscovich, T.; Hughes, J. F. (The Eurographics Association, 2005)
      This paper introduces spatial keyframing, a technique for performance-driven character animation. In traditional temporal keyframing, key poses are defined at specific points in time: i.e., we define a map from a set of ...

      Seo, Hyewon; Cordier, Frederic (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      This paper presents a new technique which makes use of deformation and motion properties between animated meshes for finding their spatial correspondences. Given a pair of animated meshes exhibiting a semantically similar ...
    • Spatial Opacity Maps for Direct Volume Rendering of Regions of Interest 

      Rodríguez-Aguilera, Alejandro; León, Alejandro (The Eurographics Association, 2016)
      Despite the mature state of the volume rendering field, its adoption in medical applications is hindered by its complex parametrization and control, and 2D slice based tools are still preferred for clinical workflows. In ...
    • Spatial Patches - A Primitive for 3D Model Representation 

      Ivanov, D.; Kuzmin, Ye. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      The commonly used solution for real-life 3D model representation is polygonal spatially consistent geometry, with texture, and, optionally, bump or displacement maps attached. Although the idea of displacement mapping is ...
    • Spatial Recognition and Grouping of Text and Graphics 

      Shilman, Michael; Viola, Paul (The Eurographics Association, 2004)
      We present a framework for simultaneous grouping and recognition of shapes and symbols in free-form ink diagrams. The approach is completely spatial, that is it does not require any ordering on the strokes. It also does ...
    • A Spatial Representation for Ray-Scene Intersection Test Improvement in Complex Scenes 

      Revelles, J.; Aguilera, N.; Aguado, J.; Lastra, M.; Garcia, R.; Montes, R. (Eurographics Association, 2003)
      We present a spatial representation based on a hierarchical structure using the well-known spatial indexing structure called octree. There are very useful spatial representations for scenes whose objects can be distributed ...
    • Spatial Splits in Bounding Volume Hierarchies 

      Stich, Martin; Friedrich, Heiko; Dietrich, Andreas (The Eurographics Association, 2009)
      Bounding volume hierarchies (BVH) have become a widely used alternative to kD-trees as the acceleration structure of choice in modern ray tracing systems. However, BVHs adapt poorly to nonuniformly tessellated scenes, which ...
    • Spatial Transfer Functions - A Unified Approach to Specifying Deformation in Volume Modeling and Animation 

      Chen, M.; Silvery, D.; Winter, A. S.; Singhy, V.; Cornea, N. (The Eurographics Association, 2003)
      In this paper, we introduce the concept of spatial transfer functions as a unified approach to volume modeling and animation. A spatial transfer function is a function that defines the geometrical transformation of a scalar ...
    • SPATIAL VIDEO Exploring Space Using Multiple Digital Videos 

      Nobre, Edmundo M. N.; Camara, Antonio S. (The Eurographics Association, 2001)
      This paper pre sents and discusses a new approach to collect, organize and explore multiple digital videos on a spatial basis. We present a methodology based on direct video frame indexation to the real space represented ...
    • Spatialized AR Polyrhythmic Metronome Using Bose Frames Eyewear 

      Pinkl, James; Cohen, Michael (The Eurographics Association, 2020)
      Polyrhythms, combinations of contrasting but mathematically related rhythms, are challenging to play, even for skilled musicians. This project entails the development of an augmented reality metronome application with an ...
    • Spatialized Transfer Functions 

      Roettger, Stefan; Bauer, Michael; Stamminger, Marc (The Eurographics Association, 2005)
      Multi-dimensional transfer functions are an efficient way to visualize features in scalar volume data produced by CT or MRI scanners. However, the optimal transfer function is difficult to find in general. We present an ...
    • A Spatially Adaptive Morphological Filter for Dual-Resolution Interface Tracking of Fluids 

      Söderström, Andreas; Museth, Ken (The Eurographics Association, 2010)
      We present a novel surface-tracking technique for free-surface fluid animations. Unlike the semi-implicit Particle Level Set method (PLS) our interface-tracking approach is purely implicit and hence avoids some of the ...
