Ray Tracing in Rust

Simple path tracer made in Rust based on Peter Shirley's book Ray Tracing in One Weekend.

To-do:

• Ray Tracing in One Weekend (actually in more than one weekend...)
• Refactor the code
• Command line arguments
• Progress bar
• Parallelism (multithreading)
• Save to a better image format (BMP)
• Load .obj files

Usage

As stated in the ./.cargo/config.toml file, this package use the rustc flag -Ctarget-cpu=native (which can be seen as equivalent to gcc/clang's -march=native flag). Thus for better performance, the produced binary should be run on the same machine on which it has been compiled.

$ cargo build --release
$ ./target/release/raytracing_in_rust --help
Raytracing in Rust 0.1.0
