Thansk for this useful project, it's helpful for learning ray tracing.
I know the ball_pyramid is used for generatng the scene file (json), and render is used for rendering.

Sorry for the late response...
It converts the JSON-format object file (e.g. https://github.com/equation314/3DRender/blob/master/scenes/glass.json) to the standard OBJ-format file, you can use other mesh software to show and debug the model.
