Center node: "ambient isotopic meshing of implicit algebraic surface with singularities"
  Abstract: A complete method is proposed to compute a certified, or ambient isotopic, meshing for an implicit algebraic surface with singularities. By certified, we mean a meshing with correct topology and any given geometric precision. We propose a symbolic-numeric method to compute a certified meshing for the surface inside a box containing singularities and use a modified Plantinga-Vegter marching cube method to compute a certified meshing for the surface inside a box without singularities. Nontrivial examples are given to show the effectiveness of the algorithm. To our knowledge, this is the first method to compute a certified meshing for surfaces with singularities.

Connected through hyperedge HE-1 (induced by source paper "homeomorphic approximation of the intersection curve of two rational surfaces"):

    - "certified approximation of parametric space curves with cubic b spline curves"
    - "arrangement computation for planar algebraic curves"
