The goal of the program is to generate images using the Raytracing protocol. Those computer-generated images will each represent a scene, as seen from a specific angle and position, defined by simple geometric objects, and each with its own lighting system.

For graphical display management and window manipulation, this project utilizes the minilibX graphics library. This library, specifically developed for students at École 42, offers a straightforward interface for creating graphic windows and managing keyboard/mouse events.

Scenes examples are located in scenes/

If you want to change the ratio, you can change the WIDTH and HEIGHT values in includes/miniRT.h

If you want to create your own scene, here are the specifications:

• Each type of element can be separated by one or more line break(s).

• Each type of information from an element can be separated by one or more space(s).

• Each type of element can be set in any order in the file.

• Lights, Spheres, Cylinders and Planes can be multiple.

• Each element first’s information is the type identifier (composed by one or two character(s)), followed by all specific information for each object in a strict order such as:
