Hello

I'm writing a loader that will read information from an external file format into the CGAL Triangulation_3 data structure. One thing that may be problematic is that the file format doesn't explicitly define the infinite cells intrinsic to CGAL's representation and so I will have to create them myself. I don't find this too daunting but I'm not sure how the neighbours of an infinite cell should be configured. It seems clear to me that the one can set the neighbour of the infinite vertex to be the finite cell sharing a facet with the infinite cell, but I'm not sure how to handle the neighbours of the other three vertices on the facet itself.

Would it be valid to set them to a random finite cell for example?

kind regards
  Simon
