Instead of checks like:

if (value === null) {
  throw new Error("missing value")
}
doSomethingThatNeedsValue(value)

texture loading

A utility for loading texture in ThreeJS. Will upload to GPU as soon as the texture is loaded, ensuring that it won't cause jank later in your application.

Example:

const loadTexture = require('./loadTexture');

// Returns a THREE.Texture object

const SimplexNoise = require('simplex-noise');
const simplex = new SimplexNoise();

module.exports = curlNoise;
function curlNoise (x, y, z, out = new THREE.Vector3()) {
  const eps = 1.0;
  let n1, n2, a, b;

  n1 = simplex.noise3D(x, y + eps, z);
  n2 = simplex.noise3D(x, y - eps, z);
