# Toy ray-tracer

JS/canvas version in top directory, Rust version in `ray` sub-directory.

Supports:

* spheres and triangles

* anti-aliasing

* point lights (hard shadows)

* sphere lights (soft shadows)

* reflections

* attenuation of lighting

The Rust version has been a bit of a playground for optimisation, check the commit log for the various things I've tried out. Blog post coming soon.

To run the Rust version:

```

cargo run --release -- out.png

```

To run the JS/canvas version - open `ray.html` in your browser (and wait, or tweak the settings so it renders in a reasonable amount of time).
