    • Variational 3D Shape Segmentation for Bounding Volume Computation 

      Lu, Lin; Choi, Yi-King; Wang, Wenping; Kim, Myung-Soo (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We propose a variational approach to computing an optimal segmentation of a 3D shape for computing a union of tight bounding volumes. Based on an affine invariant measure of e-tightness, the resemblance to ellipsoid, a ...

    • Visibility Sampling on GPU and Applications 

      Eisemann, Elmar; Decoret, Xavier (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this paper, we show how recent GPUs can be used to very efficiently and conveniently sample the visibility between two surfaces, given a set of occluding triangles. We use bitwise arithmetics to evaluate, encode, and ...

    • Volume Preservation of Multiresolution Meshes 

      Sauvage, Basile; Hahmann, Stefanie; Bonneau, Georges-Pierre (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Geometric constraints have proved to be efficient for enhancing the realism of shape animation. The present paper addresses the computation and the preservation of the volume enclosed by multiresolution meshes. A wavelet ...

    • What can Computer Graphics expect from 3D Computer Vision? 

      Sara, Radim (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Computer Vision is a discipline whose ultimate goal is to interpret optical images of real scenes. It is well understood that such a problem is cursed by ambiguity of interpretation and uncertainty of evidence. Despite ...
