Dear All,

   The file Envelope_divide_conquer_3.h has implementation of class Envelope_divide_conquer_3

This class has some public functions one of whic is meger_envelopes(mindiagram, mindiagram, mindiagram)

The document claims the purpose of this function is to merge the 1^st 2 diagrams and provided the combined diagram in the 3^rd parameter.

 

I was wondering if anyone has been able to successfully able to create the object of this class and use the above function to combine two diagrams like say voronoi diagrams or objects of type Arrangement_2 or Arrangement_on_surface_2?

 

When it try to do it, it crashes giving the following error:

 

terminate called after throwing an instance of 'CGAL::Precondition_exception'
  what():  CGAL ERROR: precondition violation!
