Description

Summary: This project is an introduction to the beautiful world of Raytracing. The "miniRT" is my ray tracing engine coded in entirely in C using only the minilibx library (for providing for creating windows and drawing pixels) adhering to norminette.

Raytracing

Ray tracing is a rendering technique that can produce incredibly realistic lighting effects. Essentially, an algorithm can trace the path of light, and then simulate the way that the light interacts with the virtual objects it ultimately hits in the computer-generated world.

To pull files ↙️

git clone git@github.com:fredch16/miniRT.git

To compile the program ↙️

$ make

To load you have to launch the program with a valid .rt scene file as a parameter 🗺️

$ ./miniRT ./scenes/scene.rt

There are some scenes in the scenes folder that showcase miniRT's capabilities.
