    • Rational Bi-cubic G2 Splines for Design with Basic Shapes 

      Karciauskas, Kestutis; Peters, Jörg (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      The paper develops a rational bi-cubic G<sup>2</sup> (curvature continuous) analogue of the non-uniform polynomial C<sup>2</sup> cubic B-spline paradigm. These rational splines can exactly reproduce ...

    • Skeleton Computation of Orthogonal Polyhedra 

      Martinez, Jonas; Vigo, Marc; Pla-Garcia, Nuria (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Skeletons are powerful geometric abstractions that provide useful representations for a number of geometric operations. The straight skeleton has a lower combinatorial complexity compared with the medial axis. Moreover, ...

    • Surface Patches from Unorganized Space Curves 

      Abbasinejad, Fatemeh; Joshi, Pushkar; Amenta, Nina (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Recent 3D sketch tools produce networks of three-space curves that suggest the contours of shapes. The shapes may be non-manifold, closed three-dimensional, open two-dimensional, or mixed. We describe a system that ...

    • VASE: Volume-Aware Surface Evolution for Surface Reconstruction from Incomplete Point Clouds 

      Tagliasacchi, Andrea; Olson, Matt; Zhang, Hao; Hamarneh, Ghassan; Cohen-Or, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Objects with many concavities are difficult to acquire using laser scanners. The highly concave areas are hard to access by a scanner due to occlusions by other components of the object. The resulting point scan typically ...
