Linework: Outlines and Edge Detection

With Linework you can easily render outlines and fill effects.

5+ years in the making, Linework is the culmination of years of experimentation that I have done with outline rendering in Unity. Made with love ❤️.

✅ Multiple techniques.

There is no one-size-fits-all solution for outlines. Linework includes multiple techniques, balancing visual fidelity and performance.

✅ Performant.

Leveraging the power of the SRP batcher and the Unity 6 Render Graph, Linework is able to render multiple outlines within a single batch.

✅ Easy to use.

A considerable amount of development time has gone into finetuning the user experience for Linework so that it is as user-friendly as possible while still being flexible.
