Vivaldi: A Decentralized Network Coordinate System. Originaly description [here](https://www.cs.umd.edu/class/spring2007/cmsc711/papers/vivaldi.pdf).This package based on source code of [Vuze](https://vuze.com/) and required nodejs >= 4.

## API

##### `create(data: Float32Array): VivaldiPosition`

Create `VivaldiPosition` instance from raw coordinates. Argument `data` should have length == 4.

##### `create(data: HeightCoordinates): VivaldiPosition`

Create `VivaldiPosition` instance from `HeightCoordinates` instance.

##### `create([error: Number]): VivaldiPosition`

Create new empty `VivaldiPosition` instance. Argument `error` is optional.

##### `update(rtt: Number, p1: VivaldiPosition, p2: VivaldiPosition|HeightCoordinates): bool`

Update position `p1` with other position `p2` and time `rtt`.

##### `distance(p1: VivaldiPosition, p2: VivaldiPosition|HeightCoordinates): number`

Calculate distace between `p1` and `p2`.

##### `equals(p1, p2): bool`

Check to equals `p1` and `p2`.

## Example

```js

const vivaldi = require('vivaldi-coordinates');

var local_pos = vivaldi.create();	// create new empty pos;

var remote_pos;	// position from some remote host

var rtt = 7;	  // ping time to remote host

vivaldi.update(rtt, local_pos, remote_pos);	// update local position

```
