Browse Source 
* pre-rebase

* broken wasm

* hull lines

* update rust lib description

* update comments, handle match statement better, pass Point type to vue

* cleanup

* add linear case

* More idiomatic code

* Further simplifications to the algorithm and removal of more heap allocations

* Rename to de_casteljau_points and use colors for the iterations

* Small comment changes

* Improve colors
