A project on Ray-Tracing and rendering three-dimensional computer-generated images. Using MiniLibX, the 42 graphical library.
Caution

MiniRT is a project that introduces the basics of Ray tracing, focusing on 3D computer-generated images from a configuration file. It includes ambient light, lights, camera, and three geometrical figures (Plane, Sphere, Cylinder). The bonus part introduces multiple lights, cones as a geometrical figure, and additional elements.
- Makefile will compile your source files. It must include 'all' and 'bonus' rules for the Mandatory and Bonus parts, respectively. It should not relink.
- You are required to use MiniLibX for this project.
- The program should be compiled using the following commands:
> ./miniRT <filename>.rt
> ./miniRT_bonus <filename>.rtWarning
Maps must have the .rt extension
Configuration file has three mandatory elements: Camera, Light and Ambient Light. And three optional geomtrical figures: Plane, Sphere, Cylinder. Each element has the following identifier:
| Name | Identifier | Name | Identifier |
|---|---|---|---|
| Ambient Light | A | Plane | pl |
| Camera | C | Sphere | sp |
| Light | L | Cylinder | cy |
