# blackbody

[![Crates.io](https://img.shields.io/crates/v/blackbody.svg)](https://crates.io/crates/blackbody)

Blackbody simply provides functions that convert temperature into color.

Codes are ported from [pbrt-v3](https://github.com/mmp/pbrt-v3).

```rust

use blackbody::{temperature_to_rgb, temperature_to_xyz};

fn main() {

    // Convert temperatue (Kelvin) into RGB color whose components are [0.0, 1.0].

    dbg!(temperature_to_rgb(3000.0));

    // Convert temperatue (Kelvin) into XYZ color whose components are [0.0, 1.0].

    dbg!(temperature_to_xyz(3000.0));

}

```

```text

[examples\example.rs:4] temperature_to_rgb(3000.0) = [

    0.73506474,

    0.3504873,

    0.112983376,

]

[examples\example.rs:5] temperature_to_xyz(3000.0) = [

    0.44889182,

    0.4151354,

    0.16

]

```
