Ray Tracer Mini

A simple ray tracer written in Rust following the Ray Tracing in One Weekend book series by Peter Shirley.

The ray tracer generates a random scene filled with spheres and leverages Rayon to deliver parallel computations.

An image with the following configurations renders in ~382 seconds in a Core i7-12700H spawning ~20 threads:

• W x H: 1200 x 800
• Samples per pixel: 500
• Recursion depth: 50
• Shapes: 486

Motion Blur and Checkered Textures:

• W x H: 800 x 450
• Samples per pixel: 400
• Recursion depth: 70
• Shapes: 486
• Render time: 21 minutes

Usage:

1. Build project: cargo build --release.
2. Configure ray tracer:
   • Edit config.toml to set image width, image height, recursion depth, samples per pixel and scene to be rendered.
   • Copy config.toml to target directory target/release.
3. Render image: ./target/release/app.
4. View image: ./target/release/image.ppm.
