## Operations

A model of this concept must provide:

Kernel::Point_3 operator() (const Kernel::Segment_3 &s, int i)
returns source or target of s: fo(s,0) returns the source of s, fo(s,1) returns the target of s. More...

Kernel::Point_3 operator() (const Kernel::Iso_cuboid_3 &c, int i)
returns the i'th vertex of c, as indicated in the figure below. More...

Kernel::Point_3 operator() (const Kernel::Triangle_3 &t, int i)
returns the i'th vertex of t. More...

Kernel::Point_3 operator() (const Kernel::Tetrahedron_3 &t, int i)
returns the i'th vertex of t. More...

## ◆ operator()() [1/4]

 Kernel::Point_3 Kernel::ConstructVertex_3::operator() ( const Kernel::Segment_3 & s, int i )

returns source or target of s: fo(s,0) returns the source of s, fo(s,1) returns the target of s.

The parameter i is taken modulo 2.

## ◆ operator()() [2/4]

 Kernel::Point_3 Kernel::ConstructVertex_3::operator() ( const Kernel::Iso_cuboid_3 & c, int i )

returns the i'th vertex of c, as indicated in the figure below.

The parameter i is taken modulo 8.

## ◆ operator()() [3/4]

 Kernel::Point_3 Kernel::ConstructVertex_3::operator() ( const Kernel::Triangle_3 & t, int i )

returns the i'th vertex of t.

The parameter i is taken modulo 3.

## ◆ operator()() [4/4]

 Kernel::Point_3 Kernel::ConstructVertex_3::operator() ( const Kernel::Tetrahedron_3 & t, int i )

returns the i'th vertex of t.

The parameter i is taken modulo 4.
