Ray tracer written in Rust

Ray tracer

Ray tracer written on Rust, based on the book "The Ray Tracer Challenge" by Jamis Buck.

What can the ray tracer do currently?

For now it can render scene using virtual "world" and camera into .ppm image format. World can hold one light source and any number of graphic primitives.

You can apply various transformations and material settings to the object. All of these factors will affect the final pixel color in the final picture.

Available graphic primitives

• Sphere
• Plane
• Cube
• Cylinder
• Cone

Examples of rendered scenes

Getting started

You can customize the scene in src/main.rs file and then render an image using cargo run, image file will be named scene.png.

cargo run --release

open scene.png

Ideas

• Scene loader from yaml config file
• Compile into WASM and run in the Web
• CLI
• Make rendering multithreaded
• Performance improvements and refactoring
