This is a Rust implementation of the Ray Tracing in a Weekend book series by Peter Shirley. The original book series is written in C++.
The goal of this project is to demonstrate how to write idiomatic Rust code, Rust's memory management, framework, tools, how to work with parallelism in Rust, futures, and async/await.
People with C++ background will find this project useful to learn Rust as they can compare the C++ code from the book series with the Rust code.
There are probably a plethora of attempts to implement this book series in Rust available on the internet, but I wanted to do it myself from scratch to avoid being spoiled by other implementations.
In the code you will find comments that explain some of the Rust concepts
that I have found interesting to pay attention to. All of them are marked
with the // LEARN comment.
Some parts of the code are intentionally done in not the most simple way, as the goal is to demonstrate different ways of doing things in Rust.
It takes a while to render the image at a high resolution, even to play with positionable camera to have a meaningful image it takes a lot of time. So the next steps would be to implement parallel execution of the ray tracer to use all available CPU cores to speed up the rendering process.
P.S.
I wish I would check the website of the book before I tried it. Because I used some buggy PDF version of it I found over the internet =)
