THREE.meshphongmaterial Not Working - Giving Black Color

Question

I am trying to use THREE.meshphongmaterial from this tutorial: http://solutiondesign.com/webgl-and-three-js-texture-mapping/

But it is not working and givi

Answer 1

Turns out it is necessary to add light. Without light, meshphongmaterial gives black color.

So I had to add something like this:

var light = new THREE.DirectionalLight( 0xffffff );
light.position.set( 0, 1, 1 ).normalize();
scene.add(light);

Got it from this link: https://github.com/mrdoob/three.js/issues/2766
