## Installation

```bash

npm install path-tangents

```

## Usage

```js

import pathTangents from "path-tangents";

// const path = ...

const closed = true;

const tangents = pathTangents(path, closed);

```

## API

## Functions





pathTangents(path, [closed]) ⇒ TypedArray | Array | Array.<vec3>





Compute tangents for a path of 3D points.





## Typedefs





vec3 : Array.<number>









## pathTangents(path, [closed]) ⇒ TypedArray \| Array \| [Array.<vec3>](#vec3)

Compute tangents for a path of 3D points.

**Kind**: global function

| Param    | Type                                                                                      | Default            | Description                                                                                                                                                        |

| -------- | ----------------------------------------------------------------------------------------- | ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ |

| path     | TypedArray \| Array \| [Array.<vec3>](#vec3) |                    | Simplicial complex geometry positions (eg. `new Float32Array([x, y, z, x, y, z, ...])/new Array(x, y, z, x, y, z, ...)` or `new Array([x, y, z], [x, y, z], ...)`) |

| [closed] | boolean                                                                      | false | Specify if the path is closed. If so the last tangent will point to the first point. Otherwise it will follow the previous point.                                  |
