# LngLatToLocaleCartesian

Convert coordinates to locale cartesian to use with webgl or others. This assume that you are using coordinates to draw polygons on a map (building or something else) and that you wish to use those points somewhere else (Three.js / D3, etc.)

## Installation

```sh

# yarn

$ yarn add converter-locale-cartesian

# npm

$ npm i converter-locale-cartesian

```

## Usage

```js

const center = [15.434, 19.0933]

const geometry = [{

  "lat": 22.31759647466327,

  "lng": 113.93006706496337

},

{

  "lat": 22.317262482317403,

  "lng": 113.93019349413271

},

{

  "lat": 22.317159427034767,

  "lng": 113.93023250571464

},

{

  "lat": 22.316962246238706,

  "lng": 113.93030714497549

},]

const lngLatToLocaleCartesian = LngLatToLocaleCartesian(center)

const points = geometry.map(({ lat, lng }) => {

  const converted = lngLatToLocaleCartesian.converter(lng, lat);

  return [converted.x, converted.y, converted.z]

}))

```
