This chapter presents an overview of the three-dimensional kernel of CGAL.
The kernel consists of elementary 3D objects (such as points, lines, planes,
etc.) and of
predicates on these objects (such as coordinate comparison, orientation,
etc.). We also provide affine transformations on these objects.
These classes are all templated by the
representation class R, which is currently either
CGAL_Cartesian<FT> or CGAL_Homogeneous<RT> for a so-called
field type FT, and ring type RT, see Chapter .
