Raytracing

subject

This project is an introduction to the beautiful world of Raytracing. It allows to render simple Computer-Generated-Images.

The goal of this 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.

binary

• minirt [file] [--save]

Receives a file containing the informations relative to a specific scenes.

The program displays the scene in a window or saves it in a bmp file with the --save flag.
