# Ray Tracing in Rust

Simple path tracer made in Rust based on Peter Shirley's book

[_Ray Tracing in One Weekend_](https://raytracing.github.io/books/RayTracingInOneWeekend.html).

To-do:

- [x] _Ray Tracing in One Weekend_ (actually in more than one weekend...)

- [x] Refactor the code

- [x] Command line arguments

- [x] Progress bar

- [x] Parallelism (multithreading)

- [x] 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

USAGE:

    raytracing_in_rust [FLAGS] [OPTIONS] 

FLAGS:

    -d, --debug       Print debug information

    -h, --help        Prints help information

    -p, --parallel    Use multithreading for rendering

    -V, --version     Prints version information

OPTIONS:

    -j         Number of threads to spawn. Default is number of logical cores

ARGS:
