    • Semi-regular Quadrilateral-only Remeshing from Simplified Base Domains 

      Daniels, Joel; Silva, Claudio T.; Cohen, Elaine (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Semi-regular meshes describe surface models that exhibit a structural regularity that facilitates many geometric processing algorithms. We introduce a technique to construct semi-regular, quad-only meshes from input surface ...

    • Separatrix Persistence: Extraction of Salient Edges on Surfaces Using Topological Methods 

      Weinkauf, T.; Guenther, D. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Salient edges are perceptually prominent features of a surface. Most previous extraction schemes utilize the notion of ridges and valleys for their detection, thereby requiring curvature derivatives which are rather sensitive ...

    • Shape Analysis Using the Auto Diffusion Function 

      Gebal, K.; Baerentzen, J. A.; Aanaes, H.; Larsen, R. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Scalar functions defined on manifold triangle meshes is a starting point for many geometry processing algorithms such as mesh parametrization, skeletonization, and segmentation. In this paper, we propose the Auto Diffusion ...

    • Smoothing of Partition of Unity Implicit Surfaces for Noise Robust Surface Reconstruction 

      Nagai, Yukie; Ohtake, Yutaka; Suzuki, Hiromasa (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We propose a novel method for smoothing partition of unity (PU) implicit surfaces consisting of sets of non-conforming linear functions with spherical supports. We derive new discrete differential operators and Laplacian ...

    • Stability of Curvature Measures 

      Chazal, F.; Cohen-Steiner, D.; Lieutier, A.; Thibert, B. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We address the problem of curvature estimation from sampled compact sets. The main contribution is a stability result: we show that the Gaussian, mean or anisotropic curvature measures of the offset of a compact set K with ...
