Dear all,

I am trying to do bool operation by CGAL basing on the OFF files. The code
is as follows:

#include <CGAL/Simple_cartesian.h>
#include <CGAL/Polyhedron_incremental_builder_3.h>
#include <CGAL/Polyhedron_3.h>
#include <CGAL/IO/Polyhedron_iostream.h>
#include <iostream>
#include <istream>
#include <fstream> 
#include <CGAL/IO/Polyhedron_iostream.h> 
#include <CGAL/IO/Nef_polyhedron_iostream_3.h> 
#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Exact_predicates_exact_constructions_kernel.h>
#include <CGAL/Nef_polyhedron_3.h>
#include "math.h"

using namespace std; 
typedef CGAL::Exact_predicates_exact_constructions_kernel        Kernel;
typedef CGAL::Simple_cartesian<double>                                 
sKernel;
typedef Kernel::Point_3                                                       
 
Point_3;
typedef CGAL::Nef_polyhedron_3<Kernel>                                
Nef_polyhedron;
typedef CGAL::Polyhedron_3<Kernel>                                      
Polyhedron;
typedef Polyhedron::HalfedgeDS                                             
HalfedgeDS;
typedef Kernel::Plane_3                                                       
 
Plane_3;
typedef Polyhedron::Vertex_iterator                                        
Vertex_iterator;
typedef Polyhedron::Facet_iterator                                         
Facet_iterator;
typedef Polyhedron::Halfedge_around_facet_circulator               
Halfedge_facet_circulator;
typedef Nef_polyhedron::Aff_transformation_3                         
Aff_transformation_3;
typedef Nef_polyhedron::Vector_3                                         
Vector_3;
 
void readoff(Polyhedron *P,char *filename)
{
  std::ifstream stream(filename);
  stream >> *P;
}

void BoolObject3(char *op, char *file1,char *file2,char *outfile)
{
    Polyhedron P1, P2;
    readoff(&P1,file1);
    readoff(&P2,file1);
    Nef_polyhedron NP1(P1);
    Nef_polyhedron NP2(P2);
    switch(*op)
    {
        case '+': NP1 = NP1 + NP2;break;
        case '-': NP1 = NP1 - NP2;break;
        case '*': NP1 = NP1 * NP2;break;
        case '^': NP1 = NP1 ^ NP2;break;
        default:break;
    }
    NP1.convert_to_polyhedron(P1);
    // output the polyhedron to OFF file
    std::ofstream log(outfile);
    std::streambuf * oldbuf = std::cout.rdbuf(log.rdbuf());

    std::cout << P1;
    std::cout.rdbuf( oldbuf);
}
int main()
{
    BoolObject3("+", "a1.off","a2.off","a3.off");
}


Thanks,
Zhanghong Tang
