# points_on_curve 〰️ 📌

This crate is a rustlang port of points-on-curve npm package written by @pshihn.

This package exposes functions to sample points on a bezier curve with certain tolerance. There is also a utility funtion to simplify the shape to use fewer points. This can really be useful when estimating lines/polygons for curves in WebGL or for Hit/Collision detections. Reverse of this operation is also supported meaning given some points generate bezier curve points passing through this points

## 📦 Cargo.toml

`[``dependencies``]`
`points_on_curve ``=` `"`0.1`"`

## 🔧 Example

`use` `euclid``::``{`default`,` point2`}``;`
`use` `points_on_curve``::`points_on_bezier_curves`;`
`let` input `=` `vec!``[`
`point2``(``70.``0``,` `240.``0``)``,`
`point2``(``145.``0``,` `60.``0``)``,`
`point2``(``275.``0``,` `90.``0``)``,`
`point2``(``300.``0``,` `230.``0``)``,`
`]``;`
`let` result_015 `=` `points_on_bezier_curves``(``&`input`,` `0.``2``,` `Some``(``0.``15``)``)``;`

## 🖨️ Output

This picture shows computed points with 4 different distance values 0.15, 0.75, 1.5 and 3.0 with tolerance 2.0.
