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 :)

Examples

./miniRT scenes/7-wolfie.rt 

./minirt scenes/cube.rt
