## Thanks and references
The original three.js bindings were made by [Lars Ivar Hatledal](https://github.com/markaren), but the project is discontinued right now.
All other libraries are explicitly shown as dependencies. We would like to express specific thanks to JetBrains Kotlin-JS team for consulting us during the work.
