Hi Christoph,

that does not sound too big, but if it is too big, you cannot do anything about it. Because of
the general opproach of Nef polyhedra, the structure is quite big and we keep it completely
in memory.

Subject: Re: [cgal-discuss] Boolean operations on Nef Polyhedra

Hi Andreas,

interesting details to know, ok. Now i used the

typedef CGAL::Simple_cartesian<CGAL::Gmpq>  Kernel;

as you suggested in the beginning of the thread. After six minutes and
1.6 Gig maximum working set size the program crashed again with the same
message, when constructing the Nef_polyhedron_3 from the Polyhedron_3.

So my question is: which kernel you would recommend? It should support
reading float values from an off file for constructing a Polyhedron_3.

The mesh consists of 188776 vertices and 378284 triangle facets.

Kind regards,
Christoph
