Ray Tracing

Overview

This is my take on Peter Shirley's Ray Tracing in One Weekend book.

This project uses the Rust programming language to achieve high performance and memory efficiency while providing many benefits such as memory- and thread-safety.

Build & Run this project

  1. Install Rust

  2. Clone the repository

  3. Build the project

    cargo build --release

  4. Run the executable

    ./target/release/rust-ray-tracing

    Display command line options

    ./target/release/rust-ray-tracing --help

Performance

I've already implemented Peter Shirley's ray tracing in various programming languages running on CPU & GPU and compared their performance.

The performance was measured on the same scene (see image above) with the same amount of objects, the same recursive depth, the same resolution (1920 x 1080). The measured times are averaged over multiple runs.
