Create a sphere made of particles with Three.js

particle-sphere.js

var distance = 100;
var geometry = new THREE.Geometry();

for (var i = 0; i < 1000; i++) {

  var vertex = new THREE.Vector3();

  var theta = THREE.Math.randFloatSpread(360);
  var phi = THREE.Math.randFloatSpread(360);

  vertex.x = distance * Math.sin(theta) * Math.cos(phi);
  vertex.y = distance * Math.sin(theta) * Math.sin(phi);
  vertex.z = distance * Math.cos(theta);

  geometry.vertices.push(vertex);
}
var particles = new THREE.PointCloud(geometry, new THREE.PointCloudMaterial({
  color: 0xffffff
}));
particles.boundingSphere = 50;

scene.add(particles);
