mat4-css-parse

Takes a transform string from an element's computed style, and returns a mat4 representation of the 3D matrix. Useful alongside mat4-css-stringify.

Cases:

• matrix3d() string
• matrix() string (returns 3D representation of the 2D matrix)
• none which results in an identity matrix

Simple example:

var parse = require('mat4-css-parse')

var mat4 = parse(computedStyle.tranfsorm)
//... now we can do some matrix operations 

Usage

matrix = parse(str[, out])

Converts the transform CSS string into a 16-float array representing a 4x4 matrix. 2D matrices will be stored in the upper left of a 4x4 identity matrix.

You can specify an out matrix parameter, otherwise it will create a new 16-length array.
