Matrix Transformer


The Matrix Transformer is a small composable library of functions that can be used to easily manipulate x,y,z coordinates in 3-D space.

#### The Concept
Manipulated 3-D coordinates is ultimately a series of mathematical operations on the original coordinates.
These operations can be combined easily using matrix multiplication. By using the functions in this library one
can transformations can be treated as a pipeline, where the data moves through the chained together functions
and comes out the other side in with the correct scale, rotation, and translation.

Getting Started

``
npm install matrix_transformer
`

Once installed import the Matrix constructor

Using es2015:
`
import Matrix from 'matrix_transformer';
`

Using pre es2015:
`
var Matrix = require('matrix_transformer');
`

Usage


Initialize a new instance of a Matrix module passing in an object with starting x, y, z coordinates:
`
let coords = new Matrix({x: 1, y: 2, z: 3});
`
##### Manipulating Individual Axes
The lowest level of manipulations can be performed on each individual axis for all three translation, scale and rotation

* Translate Axis (translateX, translateY, translateZ) takes an offset value which will be added to the coordinate

* Scale Axis (scaleX, scaleY, scaleZ) takes a scalar value which will be multiplied by that coordinate

* Rotate Axis (rotateX, rotateY, rotateZ takes a degree of rotation and applies it to that coordate.
Positive rotation is always in the counter clockwise direction.

>NOTE: order of operations MATTERS!

###### Example of individual axis manipulation:
``
let result = coords.translateX(10).scaleY(2).rotateZ(90);
console.log(result.toObject()) // output -> {x: -4, y: 11, z: 3}
``
