Hi there,

 

Another quick question for you guys.  In Section 18.5.1 in the documentation where a Extended_homogeneous<Gmpz> kernel is used to demonstrate construction of Nef_polyhedron_3 using a half-plane definition, I tried the same with Extended_cartesian<Gmpq> but this did not work – compiler errors resulted.  This documentation is found here:

 

http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Nef_3/Chapter_main.html#Subsection_18.5.1

 

It is also note worthy to mention that in the reference to Nef_polyhedron_3, there is a reference to a Extended_homogeneous_3 (presumably 3D version of the Extended homogeneous) and Extended_cartesian_3, but none of these two kernels seem to actually exist.  In the example of 18.5.1, the Extended_homogeneous (w/o “_3”)  is used to initialize a 3D plane in Nef_polyhedron_3 with success.  What am I not doing correctly to obtain the same results with Extended_cartesian<Gmpq>?

 

Thanks,

 

Stephen
