MiniRT is a basic Raytracer developed as part of the 42 curriculum. The goal was to render 3D scenes by simulating the physical behavior of light. It calculates the path of light rays, their intersections with geometric objects, and the resulting shadows and lighting effects using the Phong reflection model.
Built from scratch in C, this project utilizes the MiniLibX graphical library to handle window management and pixel rendering.
Speaking of pixels, each one's color is calculated one at a time, which corresponds to 2,073,600 pixels for 1080p. This is the ultimate project for every fan of micro-optimization, just like we are.
