A **raster signed distance field** generator

---

This project is an implementation of the technique outlined in

[Chlumsky's MSDF thesis][chlumsky-paper], which is an improvement on

[Valve's technique][valve-paper].

[chlumsky-paper]: https://github.com/Chlumsky/msdfgen/files/3050967/thesis.pdf "Shape Decomposition for Multi-channel Distance Field"

---

### Status

Currently the `rsdf_core` crate is capable of decomposing shapes made of

lines, quadratic/cubic bezier curves, and elliptical arcs,  however there is

still work to do to make it into a useful tool.

The logo above was rendered from the following multichannel SDF image, which

was generated using this codebase:

### Future work

- [ ] implement additional primitives

  - [x] elliptic & circular arcs

  - [ ] b-splines

- [ ] implement front-end asset processors (svg, fonts)

- [ ] try to parallelise the core with rustgpu
