Fun with Stateless API

Leadwerks 5 / Turbo makes extensive use of multithreading. Consequently, the API is stateless and more explicit. There is no such thing as a "current" world or context. Instead, you explicitly pass these variables to the appropriate commands.
One interesting aspect of this design is code like that below works perfectly fine. See if you can work through it and understand what's going on:
int main(int argc, const char *argv[]) { //Create a model ;) auto box = CreateBox(nullptr); //Create the world auto world = CreateWorld(); //Create a camera auto camera = CreateCamera(world); camera->Move(0,0,-5); //Create an instance of the model in the new world auto model = box->Instance(world); //Create a window auto window = CreateWindow(); //Create a rendering context auto context = CreateContext(window); while (not window->Closed()) { if (window->KeyDown(KEY_ESCAPE)) window->Close(); world->Update(); world->Render(context); } return 0; }
