FlintTracer

This is my ray tracer that I wrote while following The Ray Tracer Challenge!

This project didn't use any external library/crate, everything was done from scratch! With a high test coverge too :D

Brace yourself for a fun challenge: build a photorealistic 3D renderer from scratch!

It’s easier than you think. In just a couple of weeks, build a ray tracer that renders beautiful scenes with shadows, reflections, brilliant refraction effects, and subjects composed of various graphics primitives: spheres, cubes, cylinders, triangles, and more.

Example Scenes:

The scene used in the book cover!

How to use

To run it, do:

cargo run --bin {scene-name} | feh -

where the scene is one of

    circle
    clock
    cover
    cube
    projectile
    raytracer
    scene
    transperant

Supported Features

Objects

Cube
Cylinder
Cone
Planes
Sphere

Materials

Any material can be formed with the following combination

     color: Color,
    /// Value between 0 and 1, default: 0.1
     ambient: f64
    /// Value between 0 and 1, default: 0.9
     diffuse: f64
    /// Value between 0 and 1, default: 0.9
     specular: f64
    /// Value between 10 and 200 work best,default: 200.0
    /// no limits apart from `f64`
     shininess: f64
    /// Value Between 0 and 1.
    /// 0 is non-reflective, 1 is a perfect mirror
     reflective: f64
    /// Transparency, 0 is opaque, 1 is (perfectly) transparent
     transparency: f64
    /// Refreactive Index
     refractive_index: f64
    /// Pattern
     pattern: Pattern,

Where Pattern can be any of:

    /// Zebra like stripes
    Stripped
    /// Gradient with two colors
    Gradient
    /// Circlur Stripes
    Ring
    /// Checkers, like Chess, but in 3D space too
    Checker
    /// The Color is the Point
    NoPattern

Full fledged math library

Yep, no external crates at all!
