Ray tracing in one weekend, in Rust

This is an implementation in Rust of Peter Shirley's "Ray Tracing In One Weekend" book. This is the first of the series:

• Ray tracing in one weekend, in Rust
• Ray tracing: the next week, in Rust
• Ray tracing: the rest of your life, in Rust

Every tagged commit is the code that generates a specific image. In this way it's easy to follow the progress in the book. First git clone this project. Then you can checkout a tag to retrieve the implementation at a specific chapter in the book. For example, with git checkout tags/chapter_08.2 you get the implementation for the second image of chapter 8. With git checkout master you go back to the latest version.

Instead of implementing my own vec3, I preferred using Vector3 from nalgebra crate. For random numbers I used rand.

Hence dependencies are:

• nalgebra
• rand

What next

You can go on with my Rust implementation for the second book, "Ray tracing: the next week, in Rust".

Improvements

• I easily made the main loop parallel with the rayon crate. Just make sure that Traits are marked Sync and then it's just a matter of using an into_par_iter() iterator.
