I am trying to build a range which produces infinite random points in a triangle. To do that, I am using CGAL, which already provides the functionality to generate the random points in a triangle.
Triangle coarseTriangle = {v[0], v[1], v[2]};
CGAL::Random_points_in_triangle_2<Point> randomSamplesGenerator(coarseTriangle);
However, CGAL::Random_points_in_triangle_2
returns an iterator. In order to produce a range, I need a sentinel which always return false. Is there any sentinel like that already in range-v3 or do I have to code one myself?
You can use std::unreachable_sentinel
(Or ranges::unreachable
from <range/v3/iterator/unreachable_sentinel.hpp>
):
ranges::subrange randomSamplesRange(randomSamplesGenerator, ranges::unreachable);
