Rust Ray Tracer

This is a simple ray tracer written in Rust, inspired by the "Ray Tracing in One Weekend" series.

Building

cargo build --release

Running

To generate an image and save it to a file:

cargo run --release > image.ppm

• The output will be a PPM image file (image.ppm) in the project root.

Project Structure

• src/main.rs - Entry point, scene setup, and render loop
• src/camera.rs - Camera and ray generation
• src/hittable.rs - Hittable trait and hit record
• src/hittable_list.rs - List of hittable objects
• src/sphere.rs - Sphere implementation
• src/material.rs - Material trait and implementations (Lambertian, Metal, Dielectric)
• src/vec3.rs - 3D vector math
• src/color.rs - Color output and gamma correction
• src/interval.rs - Utility for value clamping
• src/rtweekend.rs - Math utilities and random number helpers

Notes

• Materials and objects are shared using Rc for efficient memory usage.
• The code is structured to be as close as possible to the C++ "Ray Tracing in One Weekend" book, but idiomatic to Rust.
