> Convert a 4x4 column major matrix from left handed to right handed coordinate system
Blender exports bone matrices in using a handed coordinate system, but WebGL uses a left handed coordinate system.
I used to know change coordinate systems by changing my final gl_Position's coordinates, but I now need to manipulate
coordinates before I get to my vertex shader (to find the location and rotation of a bone so that I can render something
on top of it).
This module helps me with converting everything to left handed during compile time, so that I don't need to do any
coordinate system conversion during runtime.
``sh`
$ npm install --save change-mat4-coordinate-system
`js
var changeMat4Coords = require('change-mat4-coordinate-system')
// Don't worry, both rotations and translations will be converted.
// It's just easier to demonstrate translations here.
var rightHandedMatrix = [1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 5, 1, 1]
var leftHandedMatrix = changeMat4Coords.rightToLeft(rightHandedMatrix)
console.log(leftHandedMatrix)
// [1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 1, -5, 1]
