CGAL::points_on_cube_grid_3

Definition

The function points_on_cube_grid_3 generates a given number of points on a cubic grid whose size is determined by the number of points to be generated.

#include <CGAL/point_generators_3.h>

template <class OutputIterator, Creator creator>
OutputIterator	points_on_cube_grid_3 ( double a, std::size_t n, OutputIterator o, Creator creator = Creator_uniform_3<Kernel_traits<P>::Kernel::RT,P>)
		creates the first $$n points on the regular $$ n1/3 × n1/3 × n1/3 grid within the cube $$[-a,a] × [-a,a] × [-a, a]. Returns the value of $$o after inserting the $$n points.

Requirements

• Creator must be a function object accepting three double values $$x, $$y, and $$z and returning an initialized point (x,y,z) of type P. Predefined implementations for these creators like the default can be found in Section 59.7.
• The OutputIterator must accept values of type P. If the OutputIterator has a value_type the default initializer of the creator can be used. P is set to the value_type in this case.
