Raytracer

A multithreaded raytracer implemented in rust

Running the raytracer

As every projects in rust, run with:

cargo run --release

Configuration

Everything happens in the src/main.rs file.

Resolution

Edit the HEIGHT and WIDTH constants at the beginning of the file:

const WIDTH: usize = 1920;
const HEIGHT: usize = 1080;

Scene

Objects and lights are created in the init_scene function. Add or remove them according to your needs.

For example:

let cylinder = Cylinder::new(
    Vector3::new(0.0, 5.0, 0.0),                // Position
    Vector3::new(1.0, 0.0, 1.0).normalize(),    // Direction vector *NEEDS TO BE NORMALIZED*
    0.5,                                        // Width of the cylinder
    Vector3::new(0.5, 0.5, 0.8),                // Color scaled from 0 to 1 in RGB
    0.5,                                        // Reflection index
    0.0                                         // Refraction index
);
scene.objects.push(Box::new(cylinder));         // Add the cylinder to the scene
