Mini RayTracer

aladin room using raytracing

Introduction

The miniRT is a basic program that generates 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, each with its own lighting system.

Features

The program can render the following objects:

  • Sphere
  • Cylinder
  • Plane

For the light part:

  • One light source
  • Ambient light

Instalation

Compilation Mac OS :

$> gcl https://github.com/pho8os/miniRaytracer.git

Please refer to #Compilation On MacOS

Compilation On Linux :

$> gcl https://github.com/pho8os/miniRaytracer.git

Please refer to #Compilation On Linux

Usage

$> ./miniRT maps/choose_a_map.rt

You can change the camera's coordinates, light color, sphere diameter, and other parameters.
