CxxRandomLogo

Port AtelierArith/RandomLogos.jl written in Julia to C++.

Requirements

• CMake
• Julia
  • See https://github.com/JuliaLang/juliaup to install Julia

Setup

$ git clone https://github.com/AtelierArith/CxxRandomLogo.git
$ cd CxxRandomLogo
$ make

How to use

C++ Application

Our C++ implementation provides point generation features that can be accessed from generate_points.

// main.cpp
#include <iostream>
#include <random>
#include "point_generation.hpp"

int main() {
  // 100000 points
  auto xy = generate_points();
  auto xs = xy.first; // x coordinates
  auto ys = xy.second; // y coordinates
  // header
  std::cout << "x,y" << std::endl;
  // contents
  for (int i = 0; i < xs.size(); i++) {
    auto x = xs[i];
    auto y = ys[i];
    std::cout << x << "," << y << std::endl;
  }
  return 0;
};

To build our C++ code, just run make.

$ make

We'll see that ./build/bin is generated and the executable file CxxRandomLogo corresponds to main.cpp is generated. To store results as a CSV file, just run the following command:

$ ./build/bin/CxxRandomLogo > out.csv
$ head out.csv
x,y
0,0
-0.380685,0.692171
-1.09698,0.779349
-1.61693,0.45568
0.489574,-0.189705
-0.893767,-0.739919
-0.0128572,-1.12225
-0.594527,-1.4382
-0.226511,-1.66354

We can visalize the result using Julia script named vis.jl.

$ julia vis.jl # out.png

This generates out.png
