A quick reminder on how to use openframeworks without XCode (macOS)

Using OpenFrameworks with Visual Studio Code (macOS)

  1. First, install the cpptools extension in studio code

  2. Then add the include paths in the c_cpp_properties.json file.

    If a small light bulb icon (💡) appears near the include statements on any of your source file, just click it in order to access the c_c_pp_properties.json file.

    If there's no 💡 icon, then in the project directory create a hidden folder called vscode:

// Everything is like before, we have only modified these 2 methods
// 1. Method for generating a mitchell best candidate. v2 : NOW WITH DIFFERENT RADII INCLUDED!
// PackedCircle is just a wrapper for a 2d point with a radius and the methods for drawing it
PackedCircle ofApp::getMitchellBestCandidate(){
// The more time has past, the more I want to pick smaller radii
float maxRunTime = 30 * 1000; // time in ms
float randomMin = maxRunTime / ofGetElapsedTimeMillis() / 2;
// If anything goes below 4, clamp it to 4
