Plot, an immediate mode (IM) procedural 2D drawing package for Unity, is released under the standard MIT license – however, it depends on the following third party code that happens to have other licenses:
- Earcut.net by Thomas Oberbichler, for triangulation (ISC license).
- Chroma.js by Gregor Aisch, for JCh color conversion (BSD license).
In practice, this means you need to:
- Include all licenses below in your code projects.
- Include the Chroma.js BSD lincese with your products/builds/apps.
