The RayTracer repository is made for Lut99's ray tracing renderer. The first version is simple, but trust me, it gets complicated rather fast.
The first version is made using this tutorial and its follow up.
Right now, the Scene Creator is nothing more than using the C++ compiler to create a program that transforms hardcoded objects into the JSON files that the RayTracers reads. However, to improve upon this, conventional rendering could be used to make a realtime and therefore editable 3D scene, which can then be rendered into something pretty with the RayTracer. This might be a cool project to do once some basic features of the RayTracer are up and running (like optimisation and mesh loading).
