# Light2D

Realtime 2D Raytracing in [Unity](https://unity3d.com/) using Signed Distance Fields

## Screenshots

   

## Features

- Realtime raytracing on average GPUs!

- Optimized with Jump Flood Voronoi algorithm for distance field calculation in O(log n)

- Screen space effect - supports all kinds of models/sprites/other effects

- Individual objects/layers can be in- or excluded

- Easy to set up & includes examples

### WIP! Documentation coming soon... (maybe)

## ToDo

- Allow blending RenderTextures and Light2D output

- Enable variable light texture resolutions to improve performance

- Implement nonemissive objects that still contribute to GI

- Implement subsurface scattering

- Implement Light bounces
