Hello all,

I’m created nested spheres of random points (where each sphere of differing radius represents a timeslice) that I’d like to triangulate.

I’m very close, but I’m not quite there:

inline void make_S3_triangulation(Delaunay* D3, int simplices, int timeslices) {

  // std::cout << "make_S3_triangulation() called " << std::endl;

  const int points = simplices * 4;

  const double radius = 1;

  const bool message = false;

  std::vector<Scd::Point_3> vertices;

  make_3_sphere(&vertices, points, radius, message);

  //D3->insert(vertices.begin(), vertices.end());

  for (auto point : *vertices)

    {

      D3->insert(point);

    }

}

Gives me this compiler error:
