      Chang, Qingjun; Deng, Chongyang; Hormann, Kai (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      Any point inside a d-dimensional simplex can be expressed in a unique way as a convex combination of the simplex's vertices, and the coefficients of this combination are called the barycentric coordinates of the point. The ...
    • Poisson Manifold Reconstruction - Beyond Co-dimension One 

      Kohlbrenner, Maximilian; Lee, Singchun; Alexa, Marc; Kazhdan, Misha (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      Screened Poisson Surface Reconstruction creates 2D surfaces from sets of oriented points in 3D (and can be extended to codimension one surfaces in arbitrary dimensions). In this work we generalize the technique to manifolds ...
    • Feature-Preserving Offset Mesh Generation from Topology-Adapted Octrees 

      Zint, Daniel; Maruani, Nissim; Rouxel-Labbé, Mael; Alliez, Pierre (The Eurographics Association and John Wiley & Sons Ltd., 2023)
