[![Coverage](https://codecov.io/gh/donmccurdy/three-to-cannon/branch/main/graph/badge.svg?token=S30LCC3L04)](https://codecov.io/gh/donmccurdy/three-to-cannon)

Convert a [THREE.Mesh](https://threejs.org/docs/?q=mesh#api/en/objects/Mesh) or [THREE.Object3D](https://threejs.org/docs/?q=object3d#api/en/core/Object3D) to a [CANNON.Shape](https://pmndrs.github.io/cannon-es/docs/classes/Shape.html), with optimizations to simplified bounding shapes (AABB, sphere, etc.).

## API

Installation:

```js

npm install --save three-to-cannon

```

Use:

```js

/****************************************

 * Import:

 */

// ES6

import { threeToCannon, ShapeType } from 'three-to-cannon';

// CommonJS

const { threeToCannon, ShapeType } = require('three-to-cannon');

/****************************************

 * Generate a CANNON.Shape:

 */

// Automatic (Usually an AABB, except obvious cases like THREE.SphereGeometry).

const result = threeToCannon(object3D);

// Bounding box (AABB).

const result = threeToCannon(object3D, {type: ShapeType.BOX});

// Bounding sphere.

const result = threeToCannon(object3D, {type: ShapeType.SPHERE});

// Cylinder.

const result = threeToCannon(object3D, {type: ShapeType.CYLINDER});

// Convex hull. 

const result = threeToCannon(object3D, {type: ShapeType.HULL});

// Mesh (Not recommended — limitations: https://github.com/pmndrs/cannon-es/issues/21).

const result = threeToCannon(object3D, {type: ShapeType.MESH});

/****************************************

 * Using the result:

 */

// Result object includes a CANNON.Shape instance, and (optional)

// an offset or quaternion for that shape.

const {shape, offset, orientation} = result;

// Add the shape to a CANNON.Body.

body.addShape(shape, offset, orientation);

```
