title: Three.js: What Is The Exact Difference Between Lambert and Phong?
body: <p>I understand the difference between Lambert and Phong in general computer graphics. I also understand how we can change and create our own materials using three.js. But I cannot work out the difference between MeshLambertMaterial and MeshPhongMaterial in their default states.</p>
  
  <p>I have tried switching them on a scene with one directional light source and 125 spheres, I cannot see any differences whatsoever. Three.js is being used in a chapter of my book and so I need to make sure all information is accurate and precise.</p>
  
  <p>Thanks,
  Shane</p>
