Hi!

I am currently trying to figure out the difference between the
Lazy_exact<Simple_Cartesian<Gmpq> > > kernel and the           
Filtered_kernel<Simple_Cartesian<Gmpq> > > .

The Lazy_exact uses Interval Arithmetic which is some kind of dynamic
filtering - true?

The Filtered_kernel uses then what..? If compiled without
"NO_STATIC_FILTERS" it uses static filtering, and otherwise..? Please
elaborate a bit on this topic :-) I did not find anything in the 2D and
3D Geometry Kernel manual except class definitions etc. I also already
read the paper about Interval Arithmetic.  

What is the expected performance difference between those two kernel
types?

Thank you in advance!

Yours,
