Raytracers in Rust

This repository contains a few very simple raytracer implementations written in Rust. They are listed here in increasing order of complexity:

1. raytracer_2d.rs: The simplest possible (?) raytracer that produces a 2D image with orthographic projection.

   

2. raytracer_pinhole.rs: Similar to raytracer_2d.rs but now we use a pinhole camera model for capturing the image. Also added a light source and implemented simple phong shading.

   

3. raytracer_pinhole_path.rs Implements path-based ray tracing by recursively following rays up until a maximum depth of 4. Rays are sampled randomly using a monte-carlo based approach.

The code is inspired by the book Realistic Ray Tracing (2nd Edition) by Peter Shirley and R. Keith Morley and the smallpt project.
