Generate planet surfaces

This package provides methods to procedurally generate a gas or terrestrial planet texture using sampling Perlin noise from the surface of a sphere. The generator class can be seeded to be able to generate the same pattern multiple times.

Output is a Uint8Array that contains the RGBA data that can be used for example to map to a sphere's supface with Three.js:

textureGenerator = new TextureGenerator(...); //set initial values
let noiseBuffer = this.textureGenerator.generateGasPlanetTexture(n,m); //pass size of texture
const sphereGeometry = new THREE.SphereGeometry(2, 320, 160); //example sphere
var texture = new THREE.DataTexture(noiseBuffer, n/2+1, m+1, THREE.RGBAFormat);
texture.needsUpdate = true;

const material = new THREE.MeshPhongMaterial({
    map: texture,
    blending: THREE.NormalBlending,
    shininess: 10 
});  // example material for sphere surface

const sphere = new THREE.Mesh( sphereGeometry, material );
