gl-mat4-esm

gl-mat4 ported to ES modules, so that you can do this sort of thing...

``js
import * as mat4 from 'gl-mat4-esm';

const view = mat4.lookAt(...);
`

...and take advantage of tree-shaking via Rollup and Webpack 2, rather than having to have a separate require statement for each module.

----

gl-mat4 ![stable](http://github.com/badges/stability-badges)

Part of a fork of @toji's
gl-matrix split into smaller pieces: this
package contains glMatrix.mat4.

Usage

![NPM](https://nodei.co/npm/gl-mat4/)

$3

Will load all of the module's functionality and expose it on a single
object. Note that any of the methods may also be required directly
from their files.

For example, the following are equivalent:

` javascript
var scale = require('gl-mat4').scale
var scale = require('gl-mat4/scale')
`

adjoint(out:mat4, a:mat4)

Calculates the adjugate of a mat4

clone(a:mat4)

Creates a new mat4 initialized with values from an existing matrix

copy(out:mat4, a:mat4)

Copy the values from one mat4 to another

create()

Creates a new identity mat4

determinant(a:mat4)

Calculates the determinant of a mat4

fromQuat(out:mat4, q:quat4)

Creates a matrix from a quaternion rotation.

fromRotationTranslation(out:mat4, q:quat4, v:vec3)

Creates a matrix from a quaternion rotation and vector translation
This is equivalent to (but much faster than):

`js
mat4.identity(dest);
mat4.translate(dest, vec);
var quatMat = mat4.create();
quat4.toMat4(quat, quatMat);
mat4.multiply(dest, quatMat);
``
