typedef unspecified_type | Construct_point_d |
constructor object used to construct either the center of the smallest enclosing sphere or annulus, or the points realizing the distance between the two polytopes. | |
Special types | |
The following two number types are only needed for | |
typedef unspecified_type | ET |
exact number type used to do the exact computations in the underlying solver for linear programs. More... | |

Construct_point_d | construct_point_d_object () const |
exact number type used to do the exact computations in the underlying solver for linear programs.
It has to to be a model for RingNumberType
. There must be an implicit conversion from RT
to ET
available.
number type used to return either the squared radius of the smallest enclosing sphere or annulus, or the squared distance of the polytopes.
FT
has to be either RT
or CGAL::
Quotient<RT>
if the input points have Cartesian or homogeneous representation, respectively (cf. Rep_tag
).
fast (possibly inexact) number type used to speed up the pricing step in the underlying solver for linear programs.
It has to be a model for RingNumberType
. There must be implicit conversions from RT
to NT
and from NT
to ET
available.
number type used to represent the coordinates of the input points.
