simple_generator.hpp

Generate the Fibonacci sequence:

SimpleGenerator<int> fibs(int max) {
  int a{1}, b{1}, n{0};
  for (int i = 0; i < max; i++) {
    co_yield a;
    n = a + b;
    a = b;
    b = n;
  }
}

int main() {
    // Create a generator for Fibonacci numbers
    auto generator = fibs(10);
 
    // Use the generator with a range-based for loop
    for (int value : generator) {
        std::cout << value << " ";
    }
    std::cout << std::endl;
 
    return 0;
}

Generate a sequence of vertices in a clockwise order around a vertex:

#include "meshbrane/simple_generator.hpp"
#include <meshbrane/half_edge_mesh.hpp>
 
using Vert = meshbrane::HalfEdgeVertexBase;
SimpleGenerator<Vert> *CCW_vertex_cycle(Vert &v) {
 auto h = v.h_out_;
auto h_start = h;
do {...} while (h != h_start);
