miniRT

miniRT is a simple and small ray tracer created for my studies at the 42 school codam in Amsterdam.

Usage

Just clone the repository and type make :D You will find a executable called miniRT. To showcase rendered images just run the program with one of my existing scenes.

make
./miniRT scenes/cube.rt

You can also add a --save option to save the output as a .bmp file.

./miniRT scenes/cube.rt --save

If a scene has more than one you can swap the camera in your rendered image with the right arrow key.

Scene Files

My miniRT takes a scene file as a first argument with the.rt extension. The scene file contains all the information my mini ray tracer needs to render a full image. Each element first’s information is the type identifier, followed by all specific information for each object in a strict order.

  • Resolution R
  • Ambient lightning A
  • Camera c
  • Light l
  • Sphere sp
  • Plane pl
  • Square sq
  • Cylinder cyl
  • Triangle tr

Mandatory elements are: Resolution, Ambient Light and atleast one Camera.

You find a detailed explanation of the scene file here :)
