// set up the sphere vars
// lower 'segment' and 'ring' values will increase performance
var radius = 5,
segments = 6,
rings = 6;

// create the sphere's material
var sphereMaterial =
new THREE.MeshLambertMaterial(
{
color: 0xD43001
});

// Create a ball with sphere geometry
var ball = new THREE.Mesh(
    new THREE.SphereGeometry(radius,
    segments,
    rings),
    sphereMaterial));

// add the sphere to the scene
scene.add(ball);
