CGAL users discussion list

[Doug Epps <>]

I believe (though i can't compile it right now) what Sylvain meant was to do:

CGAL::Random random;
for (int t = 1; t<4; t++) 
{       
        double randi=random.get_double (0.0, 1);
        std::cout << "randi" << randi << std::endl;
}

Note how the CGAL::Random is OUTSIDE the loop, and so is in scope for all 3 
iterations of the loop, rather than being created for each one.

My intuition is that the creation of the CGAL::Random object seeds the 
random-number generator.
So you're getting the same thing over and over.
