This module is useful to get vertices for a "full-screen quad". This is typically used for full-screen fragment shaders. You can pass the number of dimensions ( 2 - 4 ) that you wish to be outputted ( different use-cases may prefer different dimensionality ).
import FullScreenQuad from 'full-screen-quad'
const fsq = FullScreenQuad(2)
// output is a float32array of 2d vertices for your full-screen quad
