MiniRT is a C-based mini raytracer that utilizes a minimal graphics library.
A raytracer is a computer graphics technique used to create highly realistic images by simulating the behavior of light in a virtual 3D environment. In ray tracing, the fundamental concept revolves around tracing the path of light rays as they interact with objects and surfaces within a scene.
