This is the basic architecture for the Ray Tracing Teaching Tool (RT3) Project.
Most of the class are incomplete. For instance, there is no Vector3f class.
There is only an alias using Vector3f = std::array<float,3>; just to compile the project.
Replace that with your own math library.
The main.cpp calls the api.cpp, which, in turn, calls various API functions that create the objects, such as camera, integrator, scene, film.
The information to create these classes are stored in the RenderOptions struct, while the scene is being parsed.
When the parser finds the tag world_end it creates all the objects (film, camera, scene, integrator) and calls the render() method.
This method corresponds to the "main loop" of the rendering process.
