Sample code

 var scene = new THREE.Scene();
			var camera = new THREE.PerspectiveCamera(75, window.innerWidth/window.innerHeight, 0.1, 1000);

			var renderer = new THREE.WebGLRenderer();
			renderer.setSize(window.innerWidth, window.innerHeight);
			document.body.appendChild(renderer.domElement);

			var geometry = new THREE.BoxGeometry(1,1,1);
			var material = new THREE.MeshBasicMaterial({color: 0x00ff00});
			

SAMPLE CODE (2)

 var cube = new THREE.Mesh(geometry, material);			scene.add(cube);

			camera.position.z = 5;

			var render = function () {
				requestAnimationFrame(render);

				cube.rotation.x += 0.1;
				cube.rotation.y += 0.1;

				renderer.render(scene, camera);
			};

			render();
